Abstract:
In the years 2019 and 2020, a field experiment was carried out at the College Farm of the Navsari Agricultural University. The soil in the test field had a clayey texture, was low in organic carbon (0.40%), low in available nitrogen (213.42 kg/ha), medium in available phosphorus (37.55 kg/ha), and high in accessible potassium (318.27 kg/ha). The soil had a reaction pH of 7.96, which was mildly alkaline. The treatment consisted of integrated nutrient management viz., T₁ - Absolute control, T₂ - 100% RDF (20-40-00 NPK kg/ha), T₃ - 100% RDF + bio-compost @ 2.5 t/ha, T₄ - 100% RDF + bio-compost @ 2.5 t/ha + PSB (soil application @ 2.5 l/ha), T₅ - 50% RDF + bio-compost @ 2.5 t/ha, T₆ - 50% RDF + bio-compost @ 2.5 t/ha + PSB (soil application @ 2.5 l/ha) to green gram in summer season as main plot treatment, replicated four times in randomized block design. Each main plot treatment during the kharif season was divided into three sub plot treatments with three levels of recommended fertilizer dosage, namely F₁ - 100% RDF + crop residue incorporation (40-20-00 NPK kg/ha), F₂ - 75% RDF + crop residue incorporation, and F₃ - 50% RDF + crop residue incorporation in finger millet. This resulted in eighteen treatment combinations that were replicated four times in split plot design. There was a higher yield in the treatment combination T₄F₁ because, in south Gujarat, the kharif finger millet crop should be fertilized with 100% RDF + crop residue incorporation (40-20-00 N-P₂O₅-K₂O kg/ha) and the summer green gram crop should be nourished with 100% RDF + bio-compost @ 2.5 t/ha + PSB (soil application @ 2.5 l/ha).
