    Safflower (Carthamus tinctorius L.) is a species cultivated for more than two millennia and has been cultivated on all continents. This crop is an alternative for the production of oil, and for use in food and industry. The seeds of this species have oil contents that can vary from 35 to 50%. In view of this scenario, the objective of this study was to evaluate the different safflower genotypes sown in the harvest and offseason, in the municipality of Rondonópolis-MT. The experimental design was a randomized complete block design, in a plot plot subdivided 7 x 2, corresponding to: (a) the experimental design was a randomized complete block design in the experimental area of the Institute of Agrarian and Technological Sciences of the Federal University of Mato Grosso, Campus of Rondonópolis. Genotypes (PI- 237538; PI-248385; PI-250196; PI-305205; PI-306596; PI-306603; PI-613366) and sowing times (harvest and off season). Each treatment contained three replicates and each plot consisted of 5 lines of 4 m length spaced apart by 0.45 m. The data were submitted to analysis of variance, Tukey test, correlation, adaptability and stability. The genotypes PI-306596 and PI-237538 were expressed the highest potential. The sowing done in (December) provides the highest productivity yield of safflower grains. Safflower production was influenced by variables, height of flowering plants, number of chapters per plant, dry mass of chapters, mass of a thousand grains. Genotypes PI-306603, PI-613366 showed high adaptability and stability in all the methodologies studied.

    Sistemas de semeadura e manejo do solo no desenvolvimento da cultura da soja
    (Universidade Federal de Mato Grosso, 2013-12-11) Ormond, Antonio Tassio Santana; Mion, Renildo Luiz; 034.525.757-05; http://lattes.cnpq.br/8030830142710133; Polizel, Analy Castilho; 038.896.476-69; http://lattes.cnpq.br/0565510253501855; Polizel, Analy Castilho; 038.896.476-69; http://lattes.cnpq.br/0565510253501855; Mion, Renildo Luiz; 034.525.757-05; http://lattes.cnpq.br/8030830142710133; Guimarães, Geovane Lima; 684.690.805-63; http://lattes.cnpq.br/6882737457949719
    The manipulation the line spacing and plant density, aims to establish the most adequate arrangement to obtain greater productivity and adaptation to mechanized harvest. The present study aimed to evaluate the agronomic characteristics, and the operational performance of agricultural machines in the different systems soil tillage systems and soybean sowing. The experiment was conducted in field conditions in OXISOL. It was used three systems soil tillage (conventional tillage, reduced and no-tillage) and three sowing systems for soybean (conventional sowing, cross-sowing and dense sowing). The parameters evaluated were: Severity and number of pustules cm-2 of Asian rust, number of days to maturity, plant height at flowering maturation and insertion of first pod; plant population, grain yield; weight of 100 grains; chlorophyll index, stomatal density and bulk density; energetic demand of agricultural machinery. After the statistical analysis it was verified that the variables: plant height at flowering, plant population and grain yield obtained the highest performance using reduced tillage with dense sowing system. For variables insertion heights of first pod, stomatal density and number of pustule cm-2 the satisfactory results were observed with the interaction of reduced tillage of soil x cross sowing. For the severity of Asian rust and plant height at maturity interaction tillage x dense sowing showed the best results. The no-tillage system obtained the lowest energy demand and lower fuel consumption.
