Productivity, Profitability and Nutrient Status of Soil as Influenced by Integrated Nutrient Management in Chickpea-fodder Maize Cropping Sequence

Abstract

Background: Cropping system approach has gained importance in agriculture and relative enterprises. In agriculture, management practices are usually formulated for individual crops. However, farmers are cultivating different crops in different seasons based on their adaptability to a particular season, domestic needs and profitability, therefore production technologies should be developed keeping in view of crops grown in a sequence in a year or more than one year depending on the crop duration. The current study aims in application of biofertilizers and inorganic fertilizers which are essential to raise the crop yield. Rhizobium has an enormous potential to fix atmospheric nitrogen. PSB solubilize the unavailable bound phosphates of the soil and make them available to plants which increase overall plant growth resulting in 10 to 15% increase in yield. Methods: A field experiment was conducted during rabi and summer seasons of 2017-18 and 2018-19 at College Farm, Navsari Agricultural University, Navsari. The treatment consisted of five treatment of integrated nutrient management to chickpea in rabi season as main plot treatments replicated four times in randomized block design. During summer season each main plot treatment was split into four sub plot treatments with different levels of RDF to fodder maize resulting in twenty treatment combinations replicated four times in split plot design. Result: Application of 100% RDF+Rhizobium+PSB (T3) to chickpea recorded significantly higher almost all the growth attributes, yield attributes and yield, nutrient uptake, protein content and yield as well as available nutrient status in soil being remained at par with 100% RDF (T1) and 75% RDF+Rhizobium+PSB (T4). while economics was remarkably improved due to inorganic fertilizers as well as combination of inorganic fertilizers with Rhizobium+PSB to chickpea and 100% RDF (S1) to summer fodder maize significantly highest all growth and yield attributes, available nutrient status of soil and economics.
