Yield of Corn Hybrids in Western Bahia and Southwest Goiania in the Agricultural Year 2017/2018

The objective of this study was to evaluate the yield of corn hybrids in west Bahia and south-west Goias in the agricultural year of 2017/2018. The study was carried out in the municipalities of Luís Eduardo Magalhães in west Bahia - BA and Mineiros in south-west Goias – GO, Brasil. The experimental design was a randomized complete block design, the treatments being corn hybrids, 12 in west of Bahia and 23 in south-west of Goias. Each experimental unit was composed of 6 lines of 8 m in length spaced every 0.5 m and population of 70.000 ha-1 plants in 4 replications. The applications of pesticides were carried out in the morning, and the control of weeds, insects and diseases were carried out whenever necessary respecting the good practices of integrated pest management. After the harvest the yield was determined, correcting the grain moisture to 14%. Statistical analyzes were carried out at the Rbio and R interface. The analysis of variance analysis revealed that corn hybrids in the regions of west Bahia and south-west Goias were significant. The cultivation of the DKB390, MG711, DKB290 and 30F53 corn hybrids is recommended for west Bahia and the P3707 hybrid that has obtained yields above 170 sc ha-1 in south-west Goias. For both regions it was evidenced that the UPGMA grouping method using the generalized distance of Mahalanobis was efficient.
