Sowing period of forage sorghum in two places of the state of Minas Gerais

Abstract

The objective of this work was to evaluate the effect of sowing of sorghum cultivars in two locations in the State of Minas Gerais in the severity of Colletotrichum graminicola and yield of dry matter. The experiments were conducted in a randomized block design in a factorial 5 x 5 x 2, with four replications and five cultivars, five sowing dates and two locations. The first plantings were made ​​early in the second half of October, the second, third, fourth and fifth were 15, 30, 45 and 60 days after the first. The cultivars SHS500 and Volumax show greater tolerance to anthracnose regardless and city of Francisco Sá, MG and Jaíba, MG. The delay in sowing date increases the severity of Colletotrichum graminicola of sorghum, depending on the cultivar and location. The dry matter yield of sorghum is affected by sowing date and city of Francisco Sá, MG and Jaíba, MG.
