Role of Different Fertilization on Growth, Yield and Quality Evaluation in Maize (Zea mays L.) and Cowpea (Vigna unguiculata L.) Intercropping

Abstract

A field experiment had conducted during Zaid season 2022-2023. The experiment was conducted in split plot design and replicated thrice. The treatment in main plot consisted of three intercropping and in sub plots five different organic manures and different levels of fertilizers. Soil of the experiment field was clayey in texture had soil slightly alkaline, medium organic carbon (0.71%), low in available nitrogen (246.64 kg ha-1), medium in available phosphorous (21.6 kg ha-1) and high in available potassium (282 kg ha-1). A keen observation of data revealed that application of organic manures and different levels of fertilizers with intercropping both significantly influenced the growth parameters, yield parameters and yield, economic attributes like gross return, net return and B:C ratio was significantly maximum at IC2 maize + cowpea (2:1) with different organic manures and levels of fertilizers application F5 (50% RDF + 5 t FYM ha-1 + 2 t VC ha-1 + 2 t PM ha-1).
