Abstract:
A field experiment was carried out during rabi season of 2020-21 and 2021-22 at the Rajendrapur Farm, Hill Millet Research Station, NAU, Waghai (Dangs), Gujarat to find out residual effect of INM in finger millet on growth, yield and economics of chickpea under finger millet-chickpea cropping sequence. The treatments consisted of different integrated nutrient management viz., T₁: 100% RDF + Azospirillum + PSB (2 lit/ha root dipping at TP), T₂:100% RDF + NPK bio-consortium (2 lit/ha root dipping at TP), T₃: 100% RDF + Banana pseudo stem sap 1% at tillering and panicle initiation stage, T₄:75% RDF + Azospirillum + PSB (2 lit/ha root dipping at TP), T₅:75% RDF + NPK bio-consortium (2 lit/ha root dipping at TP), T₆:75% RDF + Banana pseudo stem sap 1% at tillering and panicle initiation stage, T₇:50% RDF + Azospirillum + PSB (2 lit/ha root dipping at TP), T₈:50% RDF + NPK bio-consortium (2 lit/ha root dipping at TP) and T₉:50% RDF + Banana pseudo stem sap 1% at tillering and panicle initiation stage to finger millet in kharif season as main plot treatments replicated four times in randomized block design. In rabi season each main plot treatment was split into two sub plot treatments with two levels of recommended dose of fertilizers viz., F₁-100% RDF and F₂ -50% RDF to chickpea resulting in eighteen treatment combinations. The treatment 100% RDF + Banana pseudo stem sap 1% at tillering and panicle initiation stage applied to finger millet recorded the significantly higher residual effect on growth, yields and economics of succeeding chickpea crop followed by treatments 100% RDF + Azospirillum + PSB (2 lit/ha root dipping at TP), 100% RDF + NPK bio-consortium (2 lit/ha root dipping at TP) and 75% RDF + Banana pseudo stem sap 1% at tillering and panicle initiation stage.
