Abstract
Intercropping is a sustainable way to achieve the growing demands for food and fodder of expanding population of tropical areas. Combined application of nutrient sources along with inclusion of fodder crops in cropping system will influence soil as well as plant characteristics above ground as well as below it. These sustainable approaches may increase nutrient use efficiency by rhizosphere management at soil and plant level giving better understanding of soil plant atmosphere continuum (SPAC). The present study was conducted to evaluate the effect of nutrient management and seed ratios on dynamics of root nodules of berseem as well as succeeding crop cowpea at Agronomy Research farm, National Dairy Research Institute, Haryana, India. Intensive root studies had been done regarding root parameters in berseem as well as residual succeeding crop cowpea in this research. The study revealed that 100%RDF(Recommended dose of Fertilizer)+PGPR (Plant Growth Promoting Rhizobacteria) had given maximum number of nodules (118.60) and other traits for three cuttings in terms of nutrient management and sole berseem in terms of seed ratios number of nodules (112.92), whereas 50%RDF (Recommended dose of Fertilizer) +50% FYM (Farm Yard Manure)-(62.5) and sole berseem (54.30) at harvest had shown better results in terms of residual activity on roots nodules of succeeding crop cowpea where number of nodules (62.5) and fresh wt. of root nodules (622.1 mg) at harvest in 50%RDF + 50% FYM. This research revealed that employing organic sources of nutrients like FYM (Farm Yard Manure) and biofertilizers like PGPR (Plant Growth Promoting Rhizobacteria) along with inorganics in correct proportions enhances the root traits of leguminous fodder crops and reduce sole dependency on harmful agricultural inputs. Hence, this would fulfill the long-term nutritional requirement of crop and preserve crop status in terms of quality and quantity.
