The Safflower (Cartamos tinctorius L.), can be an alternative source for renewable energy production that generates less impact to the environment as well as being a culture that can be used in human and animal food. There are few studies in the literature brasilian, about the potential of this culture. This study aimed to evaluate different conditions of harvest, treatment and storage of safflower seeds as to the physical, physiological and sanitary attributes. The experiment was conduted in Soil and Crop Production and bromatology Laboratories of the Federal University of Mato Grosso, Campus Rondonópolis. The Safflower seeds used were haversted in July 2014 in Primavera do Leste- MT. The experimental design was completely randomized design (CRD) were performed, with five replications in factorial scheme 5x2 (temperatures and packaging), 2x2 (crop rotations and cultivars) and 5x5 (doses of fungicide and storage period). The following tests were performed for evaluation of the physical attributes of the seeds: water content in the seed, weight of a thousand seeds and hectoliter weight. To evaluate the physiological attributes were performed germination, tetrazolium, accelerated aging, seedling length and electrical conductivity of the seed. To evaluate the sanitary attribute was performed "Blotter" test. Analysis of variance were made using F test and the averages were compared using Tukey test at 5% probability. The paper packaging, at the temperature of 20° C, provided greater conservation of the seed. The rotation of 692 rpm resulted in higher mechanical damage to the seeds.

The objective was to evaluate the inoculation of associative diazotrophs bacteria with Brachiaria brizantha cv. Xaraés in the first cultivation in the Cerrado Oxisol. The experiment was conducted in a greenhouse at the University Campus RondonópolisMT. The experimental design was completely randomized factorial consisting of 7x3, corresponding to seven treatments: three strains of associative diazotrophs bacteria (MTAz8, MTH2 and Y2), a combination of strains MTAz8 and MTH2, nitrogen fertilization (with nitrogen, phosphorus and potassium), witness (free of inoculation and nitrogen, but with phosphorus and potassium) here called control (no N) and absolute control (without inoculation and fertilization), and three cuts(30, 60 and 90 days) in five replications. The inoculation was performed by inserting an aliquot of 5 ml of the bacterial broth containing 108 ml-1 cells in the soil near the root zone of each plant. After each cut, was made the re-inoculation of bacteria, as well as nitrogen and potassium fertilization. There was a significant interaction effect between inoculation and cuts for most variables, the bacteria that stood out were the strains Y2 and MTH2, with increases in total dry mass of the aerial part of (8,66 and 7,27%) when compared to control without inoculation and nitrogen, even not among them. The higher nitrogen accumulation was observed in N fertilization growing over the cuts, while the inoculated treatments and control (no N) did not differ, and decreased over the cuts. Therefore, it is concluded that the nutritional characteristics, crude protein and nitrogen concentration and accumulation in Xaraés grass declined with cuts were carried to the sixty and ninety days of cultivation. The dry matter production of Xaraés grass inoculated showed an average increase of 11,32% compared treatments inoculated control without nitrogen and inoculation. The bacterial strains studied showed low competition with the microorganisms in the soil and among the bacteria studied the Y2 and MTH2 strains showed potential for FBN in association with the xaraés grass at first crop in the Cerrado Oxisol.

The vegetable ash is one alternative of fertilizant and corrective of soil positively influencing the production of marandu grass. The objective was to evaluate the response of Brachiaria brizanta cv. Marandu to the application of vegetable ash in two class of soils (Oxisol and Ultisol). The experiment was conducted in a greenhouse in the period December 2012 to May 2013. The experimental design was completely randomized in a 2x6 factorial, corresponding to two classes of soils (Oxisol and Ultisol) and six doses of vegetable ash (0; 3; 6; 9; 12 and 15 g dm-3) and six replications. We used pots with soil volume of 5 dm3 with five plants. Were made three cuts in shoot of the plants in an interval of 30 days and by occasion of each cutting was evaluated height plant, number of leaves and of tillers; shoot dry mass of leaves, stems and root (only in the third and last cut); leafs/stems ratio; SPAD reading; pH of the soil by occasion of planting and of cuts marandu grass. The results were submitted to analysis of variance by F test and when significant, the qualitative factors (soil classes) submitted to the Tukey test and the quantitative factors (doses of vegetable ash) submitted to regression analysis, both 5% probability, using the Statistical Program SISVAR. The marandu grass, in general, presented greater results in development, growth and yield when grown in Ultisol fertilized with the dose of 15 g dm-3 of vegetable ash, whereas in Oxisol were obtained in the interval of doses of vegetable ash of 9-15 g dm-3.

The vegetable ash appears as an option for owning fertilizer nutrients needed by plants that can optimize the productivity and quality of grasslands. The objective was to evaluate the production characteristics, structural and nutritional Brachiaria brizantha cultivars Marandu and Xaraés in response to doses of vegetable ash. The experiment was conducted in a greenhouse at the Federal University of Mato Grosso, Campus Rondonopolis, MT. In the period from August to December 2011. The completely randomized design, consisting of a 6x2 factorial design, plant gray doses: 0, 3, 6, 9, 12 and 15 g dm-3 and two grasses with six replications. We used pots with a capacity of 7 dm-3 of soil. Soil moisture was maintained by the gravimetric method while maintaining the ability to 60% of maximum capacity. We carried out three sections of the shoots of Brachiaria brizantha at intervals of 30 days. The SPAD readings were taken every 30 days from the seeding of Brachiaria with the use of portable meter of chlorophyll content ClorofiLOG 1030. The structural productive characteristics were evaluated and nutritional: plant height, leaf number, tiller number, leaf dry, culm dry, shoot dry, root dry, relation leaf culm relation of shoot and root dry; SPAD readings, soil pH, efficient use of vegetable ash concentrations of macro and micronutrients in shoots and roots of grasses and Marandu Xaraés. All results were submitted to ANOVA and regression Tukey mean test at 5% probability, using the statistical program Sisvar. Thus, doses of vegetable ash that provided the maximum production of shoots are between 7 and 15 g dm- 3 in the three periods. Considering the whole evaluation period, there was an increase in soil pH units from 4.36 to 6.26. There is a more efficient use of the vegetable ash to produce aerial of grasses evaluated The highest concentrations of macro and micronutrients in shoots and roots of grasses are among Marandu and Xaraés are among vegetable ash levels 4 and12 g dm-3 for evaluated in three cut. However, the vegetable ash has a positive12 influence on the yield characteristics, structural and nutritional grasses and Marandu Xaraés.

The industrial development after the population growth caused several concerns, one of which was the use of substances with heavy metals. These have xenophobic characteristics and represent a huge concern for human life, since they originate several diseases and cause the death of several biological beings. Several techniques are used to contain the contaminating power of metals. These include the use of biological materials as restraining agents or the reduction of harmful effects on biotic beings. The present work studied the influence of the Moringa extract on the reduction of heavy metals effects on the germinative process and the development of lettuce seedlings. The seeds were submitted to the twinning test with concentrations of heavy metals in mg L-1, these being Arsenic, Cadmium and Lead. For the phytotoxicity test of the extract in the germinative process, six concentrations of the extraction were used, with four replicates of each treatment. There was a significant difference among the heavy metals, the 0.9 and the 2.7 mg L-1 concentrations being the ones with the highest effects on the reduction of the seedling weight in the toxicology test. The second test showed a significant effect on germination, expressed by the concentration of 75 mg L-1 for the three metals, and also a reduction behavior in the variables of seedling and radicle sizes. The phytotoxicity test of the extract showed the power to inhibit the development of seedlings for all analyzed variables, the seedling size being the variable with greater interference in the highest concentrations of the moringa extract. The concentration 0.25 mg L, proved to be efficient in inhibiting the contaminating power of Arsenic and Cadmium.

This study aimed to evaluate the productive characteristics of cowpea inoculated with rhizobia strains and grown in Oxisol of the Cerrado of Mato Grosso. Two experiments in laboratory and the other in the field were performed. The laboratory experiment consisted of phenotypic analysis of rhizobia which were used as inocula. The experiment was conducted in the experimental farm of the Federal University of Mato Grosso, campus Rondonópolis - MT, in a randomized complete block design with seven treatments, five strains of Rhizobium (four belonging to the culture collection of UFMT, and a commercial strain BR 3267), a witness to nitrogen fertilization (75 kg N ha - 1) and a control (without inoculation or mineral fertilization), with six replicates, totaling forty two experimental units . At 40 days after sowing (DAS ) were collected from six plants of the floor area of each plot to determine the variables plant height, dry weight of shoots and roots, total dry weight, number of nodules, nodule dry mass and SPAD reading and total N of roots and shoots. In corresponding to the seed formation, at 60 DAS, period SPAD reading was performed again. At the end of the cycle relative efficiency of strains of rhizobia, weight of hundred grains, total N of shoots and roots of grain and crude protein were evaluated . Data were subjected to analysis of variance and the means were compared by Tukey test at 5 % probability, using the statistical analysis program SISVAR. The results of the laboratory experiment were acceptable for all five strains tested, all developed well in relation to the parameters analyzed. Regarding the strains used in the field experiment showed that the best results for number of nodules was the C15 strain, for the determination of nitrogen in plant tissue and grain, the strain that obtained the most satisfactory results was the strain RZ23. The commercial strain BR3267 showed greater dry mass of shoots and roots. Already nitrogen control presented higher means for SPAD readings at 40 DAS, plant height of dry mass of shoot and total.14 Inoculation with rhizobia strains contributed to the development of cowpea grown in the Cerrado of Mato Grosso.

The cerrado soil has major limitations in the availability of phosphorus to plants, requiring the management of mineral fertilizers and green manure. Thus, the objective was to: a) evaluate the pigeonpea, fertilized with phosphorus sources, lime and inoculated with rhizobia, as green manure in cerrado Oxisol b) verify the relative agronomic efficiency of reactive natural phosphate with that of triple superphosphate; c) assess the availability of nutrients in the soil, after incubation of biomass of pigeonpea d) to study the residual effect of pigeonpea as green manure in SPAD index and the productive characteristics of corn grown in succession. The study was conducted in a greenhouse in a design was completely randomized in 3x2x2 factorial with six replications. Phosphorus sources were evaluated: triple superphosphate, reactive natural phosphate and treatment without phosphorus, presence and absence of lime, and the presence and absence of inoculation. The seeds of pigeonpea cv. BRS Mandarin were inoculated with mixtures of two strains of Bradyrhizobium japonicum, and cultured for a period of 107 days after sowing. The variables analyzed were: number of leave, SPAD index, nodule number, dry weight of nodule, shoot and root. The land was returned to the vessels of their respective treatments. The plant material was ground, and 5 grams were taken samples of the dry mass of shoot and root portion for the determination of macronutrient (N, P, K, Ca, Mg and S). The other samples were returned to the pots and incubated for 90 days. After this period, samples were taken from 200 g of soil to determination of macronutrient (K, Ca, Mg and S). Then, we performed the seeding of the corn hybrid AG 1051 grown for 60 days after sowing. The variables analyzed were: SPAD index, shoot dry mass and root. The pigeonpea is directly influenced by phosphorus fertilization and liming in cerrado Oxisol. The reactive rock phosphate, compared to superphosphate has good agronomic efficiency. The availability of nutrients in the soil is greater with pigeonpea fertilized with triple superphosphate in the presence of lime and inoculated with rhizobia. Best match of dry matter production of16 maize shoots is obtained with triple superphosphate in the presence and absence of lime. Best match of dry matter production of corn root is obtained with triple superphosphate and reactive phosphate in the presence of lime.

Along with the expansion of soybean plantation, new problems came up as well, such as diseases caused by phytonematodes. Gall nematodes (Meloidogyne spp.) and (P. brachyurus) constitute two of the most important groups of nematodes for the crop. Due to the importance of these pathogens and the divergence in methodologies for the evaluation of tests to Pratylenchus spp., this paper aimed to evaluate methodologies of assembling and evaluation of tests to P. brachyurus as well as evaluate the reaction of soybean genotypes to P. brachyurus, M. javanica and M. incognita. The experiments were conducted in a greenhouse at Aprosmat, in the municipality of Rondonópolis, State of Mato Grosso, from March to November 2012. For the experiment testing methology, the experimental design was entirely at random, in factorial scheme 5x4, corresponding to five initial population levels of nematodes (0, 300, 600, 900 and 1,200 specimens of P. brachyurus) and four periods of evaluation (60, 75, 90 and 105 days after inoculation), with five repetitions. The soybean cultivars at use were: MG/BR 46 (Conquista), FMT Tabarana and TMG 115 RR. The inoculation followed different population levels. The evaluations occurred according to the period after the inoculations, amounting to the reproduction factor calculus. The second experiment was carried out in a factorial scheme 3x3, corresponding to cultivars (MG/BR 46 (Conquista), FMT Tabarana and TMG 115 RR) and containers (plastic vessels, ceramic vessels and small tubes) with six repetitions. The inoculum level used was of 600 specimens of nematodes per plant with evaluation at 90 days after inoculation. In the third experiment, the soybean genotypes tested were these ones: three lineages (UFUS 17, UFUS 02/Brown and UFUS 02) and twelve cultivars (UFUS Mineira, UFUS Uberlândia, UFUS Richness, UFUS Tikuna, UFUS Guarani, UFUS Carajás, UFUS Guará, UFUS Bahia, BRSMT Pintado (witness of11 susceptibility), MG/BR 46 (Conquista) (witness of resistance), FMT-Tabarana and TMG 115 RR) regarding the reaction to M. javanica, M. incognita and P. brachyurus. The design used was entirely randomized with 15 treatments and six repetitions. The inoculation process occurred about seven days after sowing with initial population of 600 specimens, to P. brachyurus with evaluation at 90 days and 5,000 eggs and juveniles to M. incognita and M. javanica with evaluation at 60 days. During both experiments the following variables were analyzed: SPAD reading, plant height, stem diameter, fresh and dry weight of the aerial part of the plants, root weight and reproduction factor. Every soybean genotype tested was susceptible, with FR varying from 8.33 to 23.18 to M. javanica and 6.16 to 23.0 to M. incognita. Genotypes UFUS 02 Brown and UFUS Tikuna showed FR lower than one to P. brachyurus. The ideal period for evaluation was between 75 to 89 days after inoculation, with 625 to 961 nematodes per plant. The containers used did not matter in the reproduction factor.

The nematodes are among the factors that contribute for decrease in of soybean production mainly in the central region of the country. Although the culture is attacked by various nematodes Heterodera glycines e Pratylenchus brachyurus worth mentioning, by difficulty in finding resistant cultivars P. brachyurus by the various existing physiological races of H. glycines. Faced of this scenario the objective with the present study select soybean genotypes resistant to races 1, 2, 4, 5, 6 and 14 H. glycines and P. brachyurus. The experiments were conducted in a greenhouse in a completely randomized design. The first in a factorial design 18 x 6 corresponding to soybean genotypes and races of soybean cyst nematode and the second with 12 soybean genotypes for resistance to P. brachyurus, both with five replications. The genetic material consisted of promising breeding genetic lineage of soybean, University Federal of Uberlândia program. Were included the differential cultivars Peking, Pickett, PI 88788, PI 90763, Lee Hartwig and 74 were included for characterization of races and Pintado, Conquista and crotalaria as patterns of susceptibility and resistance of P. brachyurus. Each experimental drive has been represented by two plants grown in a vase with a capacity of 1.5 dm3 of soil, containing a mixture of soil and sand in the proportion (2: 1). After seven days after sowing the seedlings were inoculated with their suspensions of 5 mL containing 3000 eggs and juveniles of H. glycines in the first experiment and 600 specimens of P. brachyurus second experiment in the root 2 cm hypocotyl. Were analyzed: plant height, stem diameter, chlorophyll index Falker and dry weight of shoot for H. glycines. After 30 days of inoculation with H. glycines, the roots were carefully removed from the vases for counting females and estimate the resistance index based on females. For P. brachyurus at 90 to days after inoculation the root system was removed for recovery nematode and calculated the reproduction factor calculated for each genotype. The genotypes UFUS 6901 and UFUS Mineira were moderately resistant to race 5 and 6, respectively .In relation to the nematode Genotypes UFUS 119, UFUS Guará, UFUS 6901, UFUS Tapajós, UFUS 8401, UFUS 7401, Villa Rica, UFUS 32 and UFUS 37 were statistically equal to the standard Crotalaria of the nematode resistance, and unfavorable or poorly suited to playing Pratylenchus spp.

The challenge is to increase agricultural production while avoiding the opening of new areas. An alternative is to increase productivity through research and development of new technologies. The spatial arrangement of plants promoted by sowing crossed of soybeans may contribute to this increase. Given the above, we sought to evaluate the performance of soybean sown of crossed shape in tillage systems. The experimental design was a split plot, with the corresponding portions of the systems of tillage and subplots to sowing soybeans types. Each treatment had six replicates. The tillage systems were: conventional tillage, reduced tillage and no-tillage. The soybean sowing was carried out in a conventional manner, with parallel lines, and so crossed, where the sower went twice in the same area in perpendicular directions. The cultivar TMG 123 RR. Evaluations consisted in checking the severity of the rust, agronomic characteristics and operational performance of machines . The lower severity of rust was observed in the no-tillage and conventional tillage with conventional sowing. The sowing crossed of soybeans had higher plant height at flowering, maturation and first pod, grain yield in no-tillage system and demanded higher fuel consumption and energy demand.

The soybean is a crop of high economic importance for the world, being one of the most exported agricultural products from Brazil, and to meet this demand each year the soybean farming has achieved high productivity using technologies such as seed treatment with bioregulators. Therefore, the objective was to evaluate the physiological quality of soybean seeds treated with different formulations containing bioregulators, and to verify how the use of these substances via seed treatment affects the development of soybean seedlings. The experiment was conducted in the city of Rondonópolis-MT in the seed laboratory of the Federal University of Rondonópolis, and in the greenhouse of the company Fast Agro. In the vegetation house the seeds were distributed in sand substrate and the evaluation was performed seven days after sowing, quantifying the germination percentage, emergence speed index and dry matter of the aerial part. In laboratory, the seeds were placed on paper substrate, 3 days after sowing, as normal seedlings, they were evaluated for total length, shoot and root, dry matter of shoot, root and total. The germination parameter was also obtained in percentage. For the experiments the soybean cultivar TMG-2185 IPRO was used and the treatments were organized into 25 formulations of bioregulators, each formulation containing different concentrations of kinetin, gibberellic acid, AIB, and substance S (confidential), a control and a formulation C (confidential). The experimental design entirely randomized with 27 treatments and 4 repetitions. The bioregulator applied via seeds increased the vigor of soybean seedlings showing positive effects on their development and significant increases in the variables seedling length and dry matter for products 9 (0.001 g of kinetin; 0.001 g of gibberellic acid; 0.001 g of IAB; and 0.3 g of substance S), 18 (0.004 g of kinetin; 0.002 g of gibberellic acid; 0.002 g of IAB; and 0.2 g of substance S), 21 (0.002 g of kinetin; 0.002 g of gibberellic acid; 0.00 g of IAB; and 0.2 g of substance S), and 26 (substance C). It was concluded that the tested bioregulators did not interfere in the germination of seeds, product 12 (0.003 g of kinetin, 0.003 g of gibberellic acid, 0.001 g of AIB, and 0.3 g of substance S) presented inhibitory effect on the growth of the root system, treatment 26 composed of formulation C was the bioregulator that most benefited the development of seedlings, product formulation 19 composed of 0, 002 g of kinetin, 0 g of gibberellic acid, 0.002 g of AIB and 0.2 g of substance S reduced the percentage of emergence and the rate of emergence of seedlings, and that the concentration of substance S of 0.3 g in the formulation of products 10, 11, 13, 16 and 0.2 g in products 18, 19, 20, 21, and 22, provided greater root length of soybean seedlings cultivar TMG-2185 IPRO.

The productivity, seed physiological quality and the disease management in soybeans are highly influenced by the production environment. Therefore, the main objective is to measure the effect of seeding systems and the soil preparation on the agronomic characteristics of soybeans, the seed physiological quality and the Asian rust development. The experiment was developed in the experimental area of the Agrarian Sciences and Technologies Institute at Federal University of Mato Grosso State. The experimental design was randomly blocking, arranged in 3x3 lines, corresponded to soil management and seeding systems, with four repetitions. The soil management used was the conventional, reduced tillage and no-till system and the seeding form were dense seeding, conventional and in crossed lines. The variables analyzed were: severity and the number of postulates per cm2 of the Asian rust; plant height at flowering, maturation and first pod insertion; Chlorophyll rate; plant lodging; number of pods per plant and number of seeds per pods; seed size; the weight of a thousand seeds; productivity; percentage of greenish seeds; vigor and viability. The crossed lines and dense seeding favored higher Asian rust development. The soil management systems and seeding influenced plant height during flowering, maturation and first pod insertion, pods number per plant and the percentage of pods with three grains, the percentage of seeds retained by 6,00 mm sieve and greenish seeds, and grain productivity. The no-till farming linked with dense seeding provided to soybean plants desirable characteristics, obtaining a higher productivity. The physiological quality of the seeds was not influenced by the cultivation systems.
