Influência da adubação de plantio na produtividade do milho verde

Abstract

This study aimed to evaluate the effects of the fertilizer planting on the yield of green maize. Evaluated were plant height, stem diameter, number of leaves per plant, leaf length and width, length, diameter and weight of ears with husk and without husk. It was used 60.000 plants/hectare plant density. The treatments were 333.33, 444.44 and 666.66 kg of fertilizer. ha (30 g. m-1 , 40 g. m-1 e 60 g. m-1 ) applying 110 kg.ha-1 of NPK 4-30-10. The experiment was arranged in a randomized block with four replications. Were measured 10 consecutive plants / plot in four blocks. Analysis of variance was performed for the data obtained and the means compared by Tukey test at 5% probability. The weight of ears with husk ranged between 335.8 g and 352.3 g / cob of husked ears and between 203.1 g and 218.9 g / cob. We conclude that, under these conditions, increased planting fertilization was not significant for the productive characters. Thus, the producer can use a lower dose of fertilizer at sowing.
