Abstract:
A field experiment was conducted at the College Farm, Navsari Agricultural University, Navsari (Gujarat) during rabi seasons of 2019-20 and 2020-21. There were nine treatments of integrated nutrient management viz., T₁-25% N through FYM + 75% RDN through inorganic fertilizer, T₂-FYM 5 t/ha + 100% RDN through inorganic fertilizer, T₃-25% N through Biocompost + 75% RDN through inorganic fertilizer, T₄-Biocompost 5 t/ha + 100% RDN through inorganic fertilizer, T₅-25% N through Vermicompost + 75% RDN through inorganic fertilizer, T₆-Vermicompost 5 t/ha + 100% RDN through inorganic fertilizer, T₇-FYM 5 t/ha, T₈-Biocompost 5 t/ha and T₉-Vermicompost 5 t/ha, were applied to coriander crop in rabi season (30kg P2O5 were applied as basal dose in treatments T₁ to T₆) and replicated three times in randomized block design. Almost all the growth attributes, yield attributes and yield were significantly improved due to combination of organic manures and inorganics. Significantly higher seed yield and stover yield were observed under the treatment of Vermicompost 5 t/ha + 100% RDN through inorganic fertilizer (T₆) which remained at par with treatment of Biocompost 5 t/ha + 100% RDN through inorganic fertilizer (T₄). The highest net return ₹ 56157/ha with B:C ratio of 1.85 were recorded under the treatment of Biocompost 5 t/ha + 100% RDN through inorganic fertilizer (T₄) followed by 25% N through Biocompost + 75% RDN through inorganic fertilizer (T₃) and 25% N through Vermicompost + 75% RDN through inorganic fertilizer (T₅).
