Abstract:
A field experiment was conducted during the Rabi season of the year 2018-19 at Research farm of Tirhut college of Agriculture Dhoil, Muzaffarpur (Bihar), to study the “Response of Potato (Solanum tuberosum L.) to Integrated Nutrient Management” with variety Kufri Ashoka. Treatments consisted of five levels of RDF (0, 75, 100, 125, 150%) and two sources of organic manures (farm yard manure @ 20.0 t/ha and spent mushroom substrate @ 4.0 t/ha). The results revealed that there was a significant difference in various plant growth and yield parameters like plant height, number of shoots, number of leaves per plant, dry matter accumulation, bulking rate of tubers, yield attributes and fresh yield of tubers due to various treatment applied in the experimentation. The outcome of the research trial revealed that treatments T5-100% RDF (150: 90: 100 N, P2O5 K2O kg/ha) + FYM 20.0 t/ha and T6-100% RDF (150: 90: 100 N, P2O5 K2O kg/ha) + SMS 4.0 t/ha gave (252.11 q/ha) and (248.15 q/ha) yield of tubers, respectively, which was found statistically at par to treatments T7-125% RDF + FYM 20.0 t/ha, T8-125% RDF + SMS 4.0 t/ha, T9-150% RDF + FYM 20.0 t/ha and T10-150% RDF + SMS 4.0 t/ha. A similar result was observed with respect to other crop growth attributes, dry matter accumulation, and yield attributes of potato. Keeping the fact of sustainable crop production as well as improving soil fertility status, the application of 100% RDF + 20 t/ha farm yard manure or 100% RDF + 4.0 t/ha spent mushroom substrate is recommended for potato cultivation.
