Production aspects of soybean cultivars in Machado region, south of Minas Gerais, Brazil
Due to its productive potential and importance in human and animal nutrition, soybeans occupya prominent position in Brazilian economy. Its cultivation in the south of Minas Gerais has beenincreasing compared to other crops; however, availability of adapted cultivars still low. Therefore,the present research was developed with the aim of evaluating different soybean cultivars productiveaspects in Machado region, Minas Gerais, in order to identify cultivars that can be recommended forcultivation in this region. The experimental design consisted of randomized complete block designwith four replications and six soybean cultivar treatments (5D6215 IPRO, 5D634 RR, NS 7709IPRO, NS 7300 IPRO, NS 7667 IPRO and NS 7200 RR). Seeding was conducted in the second weekof November/2015. It was verified that Machado region was suitable for soybean cultivation, since allcultivars presented plant height and the first legume height of insertion was favorable to mechanizedharvest. Cultivars 5D634 RR, NS 7200 RR and NS 7709 IPRO obtained the best grain yield resultswith 3.676,62, 3.612,45 and 3.377,90 kg ha⁻¹, respectively. Cultivars 5D6215 IPRO, 5D634RR, NS 7709 IPRO and NS 7200 RR are within the acceptable levels of lodging for mechanizedharvesting. On the other hand, cultivars 5D6215 IPRO and NS 7200 RR demonstrate an emergencyspeed higher than the other studied cultivars.Keywords: Glycine max (L.) Merrill. Grains Yield. Adaptability.
