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.

Economics of Bt. cotton-groundnut cropping sequence as influenced by integrated nutrient management

“…Higher level of biomass accrual and efficient translocation to reproductive parts due to supply of adequate nutrients through integrated nutrient management for different cotton treatment might be responsible for the production of elevated yield attributes, yield which resulted in higher net returns and BCR. Similar results were also reported by Radha Kumar and Reddy (2010) [10] , Shanwad et al, (2010) [13] , Mahapatra et al, (2018) [17] , Sathiya et al, (2020) [11] and Makwana and Bhanvadia (2023) [8] .…”
