Abstract:
A field trial 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 treatment consisted of integrated nutrient management viz., M₁: 100% RDN through inorganic fertilizer (150:40:00 N:P₂O₅:K₂O kg/ha), M₂: 75% RDN through inorganic fertilizer + 25% RDN through FYM, M₃: 75% RDN through inorganic fertilizer + 25% RDN through vermicompost, M₄: 75% RDN through inorganic fertilizer + 25% RDN through FYM + Bio NPK consortium and M₅: 75% RDN through inorganic fertilizer + 25% RDN through vermicompost + Bio NPK consortium to maize in rabi season as main plot treatments replicated four times in randomized block design. The results summarized that significantly higher grain and straw yields were recorded with an application 75% RDN through inorganic fertilizer + 25% RDN through vermicompost + Bio NPK consortium (M₅) but it was at par with (M₄) in two years in pooled data. Same trend was observed in nitrogen, phosphorus and potassium uptake of grain and straw of maize. On the basis of two years average, maximum net returns and BCR was recorded with the treatment 75% RDN through inorganic fertilizer + 25% RDN through vermicompost + Bio NPK consortium (M₅) followed by (M₄), (M₁) and (M₃).
