Abstract
The present study entitled “Production potential of spring groundnut (Arachis hypogaea L.)
based intercropping systems under paired skip row geometric configuration”, was carried out
at Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana,
during spring 2016. 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.
