Evaluation of agronomic characteristics of five varieties of corn in integrated crop-livestock-forest system

Abstract Text: This research aimend to evaluate the agronomic characteristics of five cultivars of maize intercropped with Brachiaria brizanthacv. Marandu. The experimental design was a randomized block with three replications and five treatments. Maize cultivars used were: EMGOPA 501, AL Bandeirantes, BRS Caimbé, PL 6880, BRS 1060. To assess the agronomic characteristics were estimated: plant height, ear height, ear number per plant and number of plants per meter. Corn EMGOPA 501 showed higher plant height, since the height of the spike was equal to cultivars EMGOPA 501 and PL 6880. The number of spike was higher in cultivars EMGOPA 501, Al Bandeirantes and BRS 1060. BRS 1060 showed fewer plants per linear meter. Considering the whole plant corn, all cultivars showed agronomic traits suitable for silage production, highlighting the variety EMGOPA 501 for plant height and ear height hence.
