Aplicación foliar de Ascophyllum nodosum y tierra de diatomeas en la producción de frijol chino y maíz

Abstract

Cowpea and corn are important as human food, being the guide cowpea, corn acts as a trellis. In these crops it is important to lookfor environmentally friendly alternatives, focused on increasing agricultural yield. The objective of the study was to determine theeffect of the application of two biostimulants, one of Ascophyllum nodosum and the other based on diatomaceous earth on theproduction of pods and grain in cowpea and corn. Cowpea and corn were planted in association in Apatzingán, Michoacán, México.The treatments consisted of the individual application of A. nodosum (AN) and diatomaceous earth (TD) at 0.5, 1.0 and 1.5 g L⁻¹and AN+TD both at doses of 1 g L⁻¹. A randomized complete block design with four replicates was used. It was found that theindividual foliar supply and in combination of the biostimulants, increased green pod yield up to 57 % and grain yield from 32.5 to42.5 %, and also increased morphological variables and yield components. The application of AN, TD and AN+TD in doses of 1 gL⁻¹, caused the highest pod production in cowpea and grain in corn.
