Residual Effect of Integrated Nutrient Management to Preceding Maize on Yield of Succeeding Groundnut under Maize-groundnut Cropping Sequence

Abstract

A field experiment was conducted at Krishi Vigyan Kendra, Anand Agricultural University, Dahod during the years 2020-21 and 2021-22 to study the effect of integrated nutrient  management in maize-groundnut cropping sequence. The residual effect of INM treatment applied to preceding rabi maize crop was beneficial for increasing growth and yield attributing characters of succeeding summer groundnut crop viz., plant height and number of branches per plant, number of pods per plant, pod yield and haulm yield per hectare as influenced by different treatments. The residual effect of combination of organic and inorganic to preceding   rabi maize crop, application of 75% RDN through inorganic fertilizer + 25% RDN through vermicompost + Bio NPK consortium (M5) produced significantly higher pod and haulm yields which was at par with 75% RDN through inorganic fertilizer + 25% RDN through FYM + Bio NPK consortium in two years of pooled data. Among the levels of RDF, directly applied to summer groundnut, significantly higher yield attribute, pod and haulm yield was recorded with the application of 100% RDF (G1) which was at par with 75% RDF + Bio NP consortium (G2) in two years of pooled experiment data.
