Abstract

A field experiment was conducted during kharif and rabi seasons of 2016–17 and 2017–18 at Rajendrapur Farm, Krishi Vigyan Kendra, Navsari Agricultural University, Waghai (Dist. Dangs), Gujarat to study the residual effect of integrated nutrient management in little millet on production potential of succeeding greengram crop under little millet greengram cropping system. The treatment consisted of integrated nutrient management viz., T1–100% RDF, T2–50% RDN through chemical fertilizer+50% RDN through biocompost, T3–50% RDN through chemical fertilizer+50% RDN through vermicompost, T4–75% RDN through chemical fertilizer+25% RDN through biocompost, T5–75% RDN through chemical fertilizer+25% RDN through vermicompost and Azotobacter and PSB applied each 2 l/ha for all treatments to little millet in kharif season as main plot treatments replicated four times in randomized block design. During rabi season each main plot treatment was split into four sub-plot treatments with four levels of recommended dose of fertilizers viz., S1– Control, S2–50% RDF, S3–75% RDF and S4–100% RDF to greengram resulting in 20 treatment combinations replicated four times in split plot design. The experiment was conducted on same site without changing the randomization of the treatment for the successive year. The application of RDF i. e. 40 kg nitrogen through 100% RDF or 75% RDN through chemical fertilizer+25% RDN through vermicompost along with recommended dose of 20 kg P2O5 reported promising effect on nutrient content and uptake, quality and yield of little millet in little millet-greengram cropping sequence under south Gujarat condition.
