Effect of foliar fertilizers on the performance of the purple corn variety improved pmv -581 (Zea mays l.) in conditions edafoclimaticas de Cayhuayna – 2017

Abstract

The investigation was carried out in the IIFO-EAP grounds. Agronomy-Cayhuayna. The analyzed variables: foliar fertilizers: Biol and Effective Microorganisms in levels of (1, 1,5 and 2 liters / backpack), which make a total of 7 treatments. The objective was to evaluate the effect of foliar fertilizer levels on the performance of purple maize in edaphoclimatic cond itions of Cayhuayna. The Randomized Complete Block design was used and Duncan's significance test was used to compare averages. The data was processed using the statistical program InfoStat. It is concluded 1. There is a significant effect of the levels of foliar fertilizers, on the size, diameter of ears, and yield per hectare in the cultivation of the purple maize variety PMV-581, with the tr eatments B / 2 and EM / 2 with 14.33 and 13.33 cm long; with 4.49 and 4.73 cm in diameter and yields per hectare of 7 500 kg and 6 846 kg / ha respectively, demonstrating that as the dose of foliar fertilizer is increased, higher yields are obtained. There is also a significant effect with respect to the concentration of anthocyanin with the B / 1 treatment with 2.14 mg of cyanidin-3-glucoside mg / 100 g under the conditions of the test; Foliar applications are recommended in the doses of 2 l / backpack every 14 days, replacing chemical fertilization to improve yields and concentration of anthocyanin.
