Residual Effect of Integrated Nutrient Management in Kharif Maize (Zea mays L.) on Growth and Yield of Toria (Brassica campestris L. var. Toria) during Rabi Season in Odisha, India

Abstract

A field experiment was carried out at Regional Research and Technology Transfer Station (OUAT), Semiliguda of Koraput district under Eastern Ghat High Land zone of Odisha in acidic soil during two consecutive rabi seasons of 2016-17 and 2017-18 to study the residual effect of integrated nutrient management in maize on succeeding toria crop. The experiment was laid out in randomized block design with three replications consisting of twelve treatments. The present investigation revealed that application of soil test based fertilizer with green leaf manure (cowpea), FYM @ 5 t ha-1 and biofertilizer (Azotobacter + Azospirillum + PSB @ 4 kg ha-1 each) to maize crop registered maximum residual effect thereby resulted significantly highest seed yield (6.3 q ha-1) and stover yield (11.1 q ha-1) of toria with a net monetary return of Rs. 7025 ha-1 and benefit cost ratio of 1.38.
