The objective of this study was to evaluate the performance of cotton fertigation with nitrogen via drip irrigation. The study was carried out in the experimental area of the Graduate Program in Agricultural Engineering of the Federal University of Mato Grosso, University Campus of Rondonópolis, from June to November 2017 and May to October 2018. The experimental design was in a randomized complete block design with four replications, in a 3 x 3 factorial scheme based on the central compound with 9 treatments, with three levels of irrigation (50, 100 and 150% ETc) via drip irrigation and three levels of nitrogen fertilization (20, 110 and 200% of 155 kg ha-1 ) via fertigation. The analyzed variables were phytometric, productive characteristics and quality of the cotton plume. The variables were submitted to statistical analysis on the response surface using software R, up to the 5% probability level. Not meeting the selection criteria of the response surface model, we studied the isolated effects and interaction of the factors through the polynomial regression analysis. In the year 2017, no significant difference was observed for the surface response model for plant height at 67.82 and 97 DAE, SPAD chlorophyll index at 67.82, 112, 127 and 142 DAE, cotton yield at cotton seed yield and fiber yield. Nitrogen fertilization of 200% N (310 kg ha-1 ) provided higher plant height (53.63 cm) at 67 DAE, SPAD chlorophyll index (54.06) at 97 DAE, cotton yield at (514.14 kg ha-1 ), cotton yield in feather (241.13 kg ha-1 ) and water use efficiency (2.30 kg ha-1 mm -1 ). The irrigation of 110% ETc provided higher cotton seed yield (469.34 kg ha-1 ) and feather (234.00 kg ha-1 ). In the year 2018, all variables were adjusted to the surface model of responses, except stem diameter at 55 DAE, SPAD chlorophyll index at 70 DAE and fiber yield in the two years of cultivation. Nitrogen fertilization and irrigation have a positive influence on herbaceous cotton production with significant gains in its production.

The use of wood ash as an alternative fertilizer is a way to reduce the costs of recovery systems in addition to targeting the solid waste. The objective of this study was to evaluate the productive, phytometric and chlorophyll index of Marandu grass in recovery with doses of wood ash and forms of application of the residue in pasture grown in Typic Quartzipsamment. The experiment was conducted on field in an area cultivated with Marandu grass, at the Instituto Mato-Grossense do Algodão (IMA). The experiment was conducted in the rainy season for two consecutive years (2015 and 2016). Six doses of wood ash (0, 3, 6, 9, 12 and 15 t ha-1 ) were applied with two forms of application, not incorporated and incorporated into the soil with light offset disk harrow. The experimental design was a randomized complete block design, with four replications. The main experimental units (8x30m) received the doses of wood ash, while the application form was allocated to the subplots (8x15m). Nitrogen fertilization was 100 kg ha-1 using as urea source, carried out in two years. Four cuttings of the plant material were carried out, with 30 days intervals, the first one being carried out after 30 days of the application of the wood ash. The cuts were performed using a base rectangle in the dimensions of 1.00X0.25 m, with a height of 5 cm, cast in the useful area of each subplot. The variables analyzed were: chlorophyll index, plant height, number of leaves and tillers, shoot dry mass, leaves and stems + sheaths and dry mass accumulation in the two years of pasture recovery. The data were submitted to analysis of variance and when significant the doses of wood ash were submitted regression analysis and the form of application of the residue to Tukey test, both up to 5% of probability, through the statistical program SISVAR. The productive characteristics of pasture in recovery were positively influenced by the fertilization with wood ash at doses above 15 t ha-1 when incorporated into the soil in the production of dry mass of the aerial part and for dry mass of leaves the management that stood out was the not incorporated. The phytometric characteristics obtained better results in the doses of wood ash above 9.86 t ha-1 in the handling incorporated for the height of plants and not incorporated for number of tillers, the other variables were influenced in the doses of wood ash up to 15 t ha -1 . The doses and the forms of application of vegetal ash influenced the development of the forage grass in the two years of evaluations of the experiment.
- ItemCultivo de crisântemo sob adubação mineral, cinza vegetal e organomineral associado à calagem(Universidade Federal de Mato Grosso, 2022-02-18) Meneghetti, Luana Aparecida Menegaz; Silva, Edna Maria Bonfim da; 960.432.454-34; http://lattes.cnpq.br/8660058048761423; Silva, Edna Maria Bonfim da; 960.432.454-34; http://lattes.cnpq.br/8660058048761423; Duarte, Thiago Franco; 011.291.431.47; http://lattes.cnpq.br/7076042826792327; Silva, Tonny José Araújo da; 781.203.064-49; http://lattes.cnpq.br/0651075688988405; Pinheiro, Everton Alves Rodrigues; 021.810.303-40; http://lattes.cnpq.br/2790021654126083The production of ornamental flowers in Brazil is an activity of great economic importance in the country. For the vigorous development of flowers, it’s necessary to properly manage soil fertility. The objective was to evaluate different types of fertilization under two levels of liming in the development and production of potted chrysanthemum in Oxisol, cultivated in a greenhouse. The experiment was carried out at the Federal University of Rondonópolis, in a greenhouse of the Postgraduate Program in Agricultural Engineering. The experimental design was in randomized blocks, with a 5x2 factorial scheme, with five types of fertilization (incubated wood ash, non-incubated wood ash, organomineral (50% mineral fertilizer and 50% wood ash), mineral fertilizer and control) and two types of liming (with liming and without liming), with five replicates, totaling 50 experimental units (UEs). The soil used in the experiment was the Oxisol and the chrysanthemum cultivar used was the white Singelo. The variables analyzed are plant height, number of leaves, leaf area, root volume, dry mass of roots, chlorophyll index, water use efficiency, total water consumption and soil chemical characteristics (pH, macronutrients and micronutrients). The data were submitted to analysis of variance by the F test, and when significant they were submitted to the Tukey test at 5% probability. The SISVAR software was used to perform the statistical analysis. The productive and phytometric variables were significant only for fertilization in isolation, except for plant height, which was significant for factor liming and fertilization in isolation. There was interaction between the factors in pH. All chemical characteristics and macronutrients were statistically significant for the types of fertilization and liming, except for sulfur, which was significant only for types of fertilization. There was interaction between the factors in the variables aluminum (Al), magnesium (Mg) and base saturation (V%). Regarding micronutrients, except for iron, treatments with liming and fertilizers with wood ash in their composition provided a higher content of these nutrients in the soil. Wood ash reduces the dependence on liming and mineral fertilizer in potted chrysanthemum plants. Organomineral fertilizer is an alternative for reducing the volume of wood ash and the use of mineral fertilizer. Wood ash is an alternative fertilizer for growing potted chrysanthemum.
- ItemParametrização do modelo AquaCrop e simulação da transpiração e produtividade do algodoeiro sob lâminas de irrigação e nitrogênio(Universidade Federal de Mato Grosso, 2021-08-31) Fernandes, Werlen de Souza; Duarte, Thiago Franco; 011.291.431.47; http://lattes.cnpq.br/7076042826792327; Duarte, Thiago Franco; 011.291.431.47; http://lattes.cnpq.br/7076042826792327; Silva, Tonny José Araújo da; 781.203.064-49; http://lattes.cnpq.br/0651075688988405; Fenner, William; 029.533.101-18; http://lattes.cnpq.br/2509207331637862The cotton plant Gossypium L. is an agricultural species of great economic and social importance for Brazil, whose demand for technologies that enhance productivity combined with sustainability, should be constantly sought. Productivity simulation models, such as AquaCrop, allow the determination of the response of the crop as a function of variation in water availability and nitrogen fertilization. Thus, this work aimed to parameterize the AquaCrop model to evaluate the yield of cotton as a function of water and nitrogen levels. The experiment was conducted in the experimental area of the Federal University of Rondonópolis. The soil is classified as dystrophic Red Latosol and the cultivar used was the IMA5801B2RF. Irrigation was by drip system with irrigation rates of 30%, 90%, and 150% of crop evapotranspiration. Nitrogen was applied via fertigation at doses of 20, 110, and 200% of the recommended dose for cotton. The model input parameters determined locally were soil physical parameters: field capacity (10 kPa), permanent wilting point (1500 kPa), saturated hydraulic conductivity (constant load permeameter); vegetative parameters: canopy cover (%); duration of phenological stages (days); maximum depth of the root system (m); meteorological parameters: maximum and minimum air temperature (ºC), relative humidity (%), wind speed (m s-1 ), global solar radiation (MJ m2 d -1 ). After parameterization, the model was calibrated to simulate the effect of nutrient (N) stress. Seed cotton yields were 3495 kg ha-1 (ET90N110), 2027 kg ha-1 (ET90N20), and 2075 kg ha-1 (ET30N110). Regarding the simulation, it was observed that the simulation of the productive variables, biomass, and seed cotton, by the AquaCrop model were higher than the measured data. In general, the largest errors occur for the simulation of treatments with water or nutrient stress. Despite this, the statistical parameters R2 , d and c, were greater than 0.90, which classifies the model performance as "optimal".
- ItemProdução da cultura do morango semi-hidropônico em diferentes sistemas de cultivo(Universidade Federal de Mato Grosso, 2017-02-27) Castro, Hamilton Abraham Weimar; Silva, Tonny José Araújo da; 781.203.064-49; http://lattes.cnpq.br/0651075688988405; Silva, Tonny José Araújo da; 781.203.064-49; http://lattes.cnpq.br/0651075688988405; Duarte, Thiago Franco; 011.291.431.47; http://lattes.cnpq.br/7076042826792327; José, Jefferson Vieira; 315.083.978-56; http://lattes.cnpq.br/0180791633456689; Koetz, Marcio; 892.874.600-00; http://lattes.cnpq.br/8918968565917194Strawberry is a crop of great economic importance in the horticultural sector at national and international level, due to the high demand of labor, generating jobs and consequently improving the quality of life of families. The area of strawberry production grows every year and with this arises the need to develop new production technologies and choices of cultivars appropriate to adapt to the southern region of Mato Grosso. The objective was to evaluate the performance, production and quality of strawberry fruits using three cultivars submitted to different cultivation systems in protected environment. The experiment was conducted at the Federal University of Mato Grosso, Campus of Rondonópolis, under greenhouse conditions. The design was in randomized blocks, in subdivided plots, using three cropping systems as main plot: Zeer pot (ceramic blocks), plastic pots and Slab (plastic bags), and the subplots with three strawberry cultivars: San Andreas, Oso Grande and Albion, with four repetitions, totaling 36 subplots. For the formation of the substrate were mixed soil and commercial substrate. The irrigation system was drip irrigation, using self- compensating drippers (Naan). A nutrient solution was prepared according to the stages of development of the strawberry. Performance characteristics were evaluated as leaf and flower numbers, leaf area, shoot dry mass; the productive part of the plants and the quality of the fruits were also evaluated. The crops systems influenced the performance of strawberry plants in the protected environment in the region of Rondonópolis-MT, except for the fruit qualities that were not influenced by cropping systems. The systems that provided better development of the strawberry cultivars were the plastic pots and Slab, respectively, while the ceramic block system provided the least development of the strawberry plants. The San Andreas and Albion varieties had the greatest plant development.

However, available water and soil fertility are among the main factors affecting productivity. Purpose: To evaluate the products characteristics, fruit quality and use of water of cherry tomato crop under water availability and potassium rates, cultivated in a pot with Oxisol in a protected environment. Material and Method:The experiment was conducted in a greenhouse with a randomized block design in a 5x5 factorial scheme, with five soil water availability (4, 14, 24, 34 and 44 kPa) and five potassium doses (0, 125, 250, 375 And 500 mg dm-3), in a fractional factorial arrangement 5² based on the central compound adapted by Littell & Mott (1975), resulting in 13 treatments (4 - 0; 4 - 250; 4 - 500; 14 - 125; 14 - 375; 24 - 0; 24 - 250; 24 - 500; 34 - 125; 34 - 375; 44 - 0; 44 - 250; 44 - 500) (kPa - mg dm-3). The drip irrigation system with semi-automated irrigation control. As analyzed variables were related as vegetative, productive, fruit quality and cherry tomato water use. Results: As leaf and root dry masses and root volume presented increases of 40 to 54% with increase of potassium fertilization up to a potassium dose of 500 mg dm-3. There was a significant relationship between water availability and potassium doses for dry stem and shoot species, which showed increases in production of 74 and 62%, respectively, with a higher production in the combination of 4 kPa and 500 mg dm-3 of potassium when compared to the treatment of 44 kPa and 0 mg dm-3 of potassium. The mean fruit mass, transverse and longitudinal diameter and pulp thickness of fruits showed reductions from 16 to 44% with increasing soil water tension up to 44 kPa. Soluble solids have a higher potassium dose value of 326 mg dm-3. The highest productivity was observed in the soil water availability of 24 kPa and in the potassium dose of 290 mg dm-3. The highest water use efficiency was observed in soil water tension of 44 kPa and potassium dose of 290 mg dm-3. Conclusion: The water availability and the potassium doses influence in an isolated way the vegetative, productive development, quality of the fruits and water use by cherry tomato cv. BRS Iracema.
