Agronomic Performance of Corn Genotypes in a Consortium with the Bean Variety IAC Alvorada

Abstract

The corn crop is among the most important activities in Brazil, as one of the main export products. The objective of this work was to analyze agronomic performance of maize genotypes in a consortium with the bean variety IAC Alvorada. The experiment was conducted in 2014 in the months from August to December in the experimental area of the Federal University of Alagoas in Rio Largo city, and used a randomized block design in a factorial scheme (4x2) four corn genotypes: Alagoano, Viçosense, Nordestino and BRS 5037 (Cruzeta) in two production systems, plus a complementary treatment. We evaluated the following variables for corn: plant height, stem diameter, the first ear height, weight hundredfold, number of grain row, yield and equivalent production of corn. For beans was evaluated grain yield. The polyculture showed higher equivalent corn yield, 21,270 kg ha. He Viçosense, Nordestino and Alagoano genotypes (4640 kg ha) showed the highest production yields. The consortium did not influence in any of corn agronomic characteristics. The genotypes showed favorable rates of cropping systems. Short Research Article Carvalho et al.; JEAI, 30(3): 1-7, 2019; Article no.JEAI.46624 2
