The soil of the experimental field was sandy loam, normal in pH and electrical conductivity, while low in organic carbon and available N, medium in available P and low in available K. In the experiment sowing of two genotypes was kept in the main plots, each main plot was divided into 7 sub plots to allocate the intercropping system along with sole planting of spring groundnut with skip row geometric configuration and the component crops (sown at skip row between spring groundnut) to calculate the different intercropping indices. This experiment was laid out in a split plot design with three replications. The results showed that growing of TAG 37A genotype of spring groundnut sole as well as intercropping system gave higher yield, spring groundnut equivalent yield, system productivity and economic returns as compared to SG 99 genotype. Yield of intercrops was not influenced by genotypes. Among different intercropping systems, spring groundnut + maize (fodder) recorded significantly higher spring groundnut equivalent yield, system productivity, LER and the economic returns as compared to sole spring groundnut and all other intercropping systems. This system was also found to be most effective to achieve the best land utilization, maximum productivity, monetary as well as intercropping advantage.ennullThesis
