Desempenho de híbridos para a produção de milho verde e armazenamento pós-colheita.

Abstract

Green maize arouses great interest in the farmer due to the fact that it presents demand throughout the year and provides income aggregation to farmers, but little attention has been paid to research on hybrids for the production of green and postharvest maize. In this context, the objective of this work was to evaluate the performance of hybrids for the production of green maize and post-harvest storage. The research was developed in the period from August to November of 2017, in Sítio Boa Vista located in the municipality of São Domingos-PB. The treatments consisted of two maize hybrids (AG 1051 and AG 8677) and two types of storage (environment and modified environment). The experimental design was a randomized block design in a 2 x 2 factorial scheme, with five replications and for the characteristics evaluated in the field, in the comparison only among the hybrids, the randomized block design was used, with fourteen replications. The following variables were evaluated: length of the spiked spindle and shrub, the diameter of the spiked and spiked spindle, the diameter of the cob, weight of spiked ears and marketable debris, weight of the cob, weight of the straw, weight of the grains, number of rows, number of grains in each spike, number of spikes per plant, productivity and weight loss. The modified environment was more effective in reducing weight loss during storage. The marketing of green maize at the producer level is by weight recommended AG 1051 and for ears AG 8677.
