Abstract:
A field experiment to study the influence of different nutrient sources on growth and yield attributes and yield of mustard (Brassica juncea L.) was conducted during rabi 2020-2021 at Experimental Farm, Agronomy, Oilseeds Research Station, Latur. The objectives of the present study was to study the effect of different nutrient sources on growth and yield of mustard. The soil was clayey in texture, low in available nitrogen, very low in available phosphorus, very high in available potassium and alkaline in reaction. The experiment was laid out in Randomized Block Design with 8 treatments each with three replications. The treatments were T₁ – Control, T₂ - RDF + FYM @ 5 t ha^-1, T₃ - RDF + Vermicompost @ 2.5 t ha^-1, T₄ - RDF + Poultry manure @ 5 t ha^-1, T₅- RDF + Elemental sulphur @ 20 kg ha^-1, T₆ - RDF + ZnSO₄ @ 20 kg ha^-1, T₇- RDF + FeSO₄ @ 20 kg ha^-1 and T₈ - RDF + Gypsum @ 500 kg ha^-1. The gross and net plot size was 5.4 m x 4.5 m and 4.5 m x 3.9 m, respectively. Sowing was done on 12^th November, 2020. The recommended dose of fertilizer was applied as per treatments through Urea, DAP and MOP. The crop was harvested on 23^rd February, 2021. The results of the experiment indicated that combined application of RDF + Vermicompost @ 2.5 t ha^-1 (T₃) observed significantly maximum growth parameters viz., plant height, number of branches, number of leaves, leaf area and dry matter and yield and yield attributes viz., number of silique plant^-1, length of silique (cm), number of seeds silique^-1, seed yield plant^-1 (g), straw yield plant^-1 (g), test weight (g), seed yield (kg ha^-1), straw yield (kg ha^-1) and biological yield (kg ha^-1), but statistically remained at par with RDF + FYM @ 5 t ha^-1 (T₂) and RDF + Gypsum @ 500 kg ha^-1 (T₈).
