“…The sunflower cultivation area has largely expanded in Brazil due to the establishment of achenes processing industries in producing regions, adequate oil yield for food industries, increase in the crop production technology, cultivars with acceptable adaptability and stability in growing conditions, early cycle and satisfactory yield to the producer (Furtado & Chaves, 2018;Dalchiavon, Lorenzon, Perina, Oliveira, & Santos, 2019).…”

Precision in sowing is an important strategy for increasing agricultural yield. The objective of this study was to evaluate the influence of seed distribution mechanisms and sowing speeds on characteristics of sunflower. The experiment was set in March 2015 in São José do Rio Claro, state of Mato Grosso (Brazil). The experimental design was a completely randomized block design, in a 2 × 5 factorial arrangement, with two seed distribution mechanisms (perforated and pneumatic disc) and five sowing speeds (4; 6; 8; 10 and 12 km h -1 ) with four repetitions. The vegetative and reproductive characteristics of the sunflower were evaluated and also the double, faulty and acceptable spacing were evaluated to observe the homogeneity of seed distribution through the sowers. Regardless of the seed distribution mechanism, the rise in the sowing speed caused a reduction in plant population by changing plant height, head height, head mass, achene mass per head, mass of one thousand achenes and head diameter. The perforated disk distribution mechanism showed the best performance in acceptable spacings and the pneumatic one provided a greater guarantee of the desired plant population. The different distribution mechanisms, as well as different sowing speeds, did not influence achenes yield. The farmer should be aware of the speed of sowing adopted in his sunflower crop, as increasing speeds may affect uniform seed distribution as well as plant development.

“…The municipality of Campo Novo do Parecis, in the Cerrado/Savannah of Mato Grosso, grew 40% of all sunflower crop in the state. High sunflower production in the region is mainly due to industrialization and to the region's excellent edaphoclimatic conditions for its culture, such as altitude and well-defined dry season (Birck et al, 2017;Dalchiavon, Marchesini, Kimecz, Machado, & Carvalho, 2018;Dalchiavon, Lorenzon, Perina, Oliveira, & Santos, 2019;Dalchiavon, Marcondes, & Carvalho, 2020). The sunflower's agronomic features, such as tolerance to draught, heat and cold, nutritional and commercial value, plus the fact that agricultural systems have integrated crops for production improvement, favored the cultivation of the sunflower plant in the Cerrado of Mato Grosso as second harvest, with sowing between Diabrotica speciosa; at 37 DAE for the control of Spodoptera frugiperda and at 70 DAE for the control of Chlosyne lacinia saundersii.…”

Helianthus annus L. belongs to the family Asteraceae, with a yearly cycle and high adaptability rate to different climate conditions. Its culture was boosted by the production of animal feed, oil extraction for humans or for biodiesel, ornamentation and bird feed. The agronomic performance of sunflower genotypes in the Mid-Northern region of the State of Mato Grosso, Brazil, was assessed. Data for the production and industrial sectors will be thus provided for the selection of genotypes with the best agronomic traits when cultivated in the region. Current study was performed at the Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso, on the Campus Campo Novo do Parecis MT Brazil, during 2018. Eight genotypes were evaluated in assays with randomized blocks and four replications. Evaluated traits comprised days for initial florescence, plant height, stalk diameter, green and dry mass, days for physiological maturity, mean diameter of the head, mass of head and achenes per head, both necessary to obtain achene:head ratio, mass of one thousand achenes, number of achenes per head and productivity of achenes of the oil. Genotypes with high grain yield tended towards greater size and cycle. Genotypes SYN 045, BRS 323 and MULTISSOL had good grain productivity plus good production of green and dry mass. The first two genotypes had an oil rate above 40%, with good oil productivity.
