Cumulative and residual effect of <em>kharif</em> maize fertility treatments on growth & nutritional quality of vegetable onion

Abstract

A field experiment is conducted to study the direct, cumulative and residual effect of fertility treatments on vegetable onion. The results revealed that the highest dry matter, N, P, K & S and micro nutrient content and uptake both in leaf and bulb under fertilized cumulative field condition. Vegetable onion grown on preceding maize fertility treatments shown significant variation in growth and nutrient content among the direct, cumulative and residual strips. Vegetable onion responded well under integrated use of organic and inorganic source of nutrients and biofertilizer treatments of preceding maize both under cumulative and residual treatments over other inorganic sources of nutrients to preceding maize crop.
