Effect of Organic and Inorganic Manure on Yield, Quality Trait and Economics of Potato (Solanum tuberosum L.) under Indo Gangetic Plain of Eastern Uttar Pradesh

A field experiment was conducted during 2018-19 at Main Experiment Station Vegetable Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) with a view to find out the effect of different combination of organic manures on yield, tuber quality and net income of potato. The 7 treatment combinations consisted of T1: Absolute Control, T2: FYM 30t ha-1 + PSB, T3: Poultry manure 5t ha-1 + PSB, T4: Vermicompost 7.5t ha-1 + PSB, T5: FYM 10t ha-1 + Poultry manure 1.7 t ha-1 + Vermicompost 2.5 t ha-1, T6: 67% N through Urea and 33% N through FYM + PSB, T7: Farmer practices FYM 15t ha-1 + Vermicompost 1t ha-1 + PSB were tested in randomized block design with 3 replication on the basis of experiment result it was revealed that treatment T6 shows better tuber yield (38.41 t ha-1),tuber yield grade wise i.e. 0-25g (1.93 t ha-1), 25-50g (11.52 t ha-1), 50-75g (14.58 t ha-1) and >75g (10.37 t ha-1) respectively, grade size of tuber per hill 0-25 (0.300 kg), 25-50 (0.800 kg), 50-75 (1.2 kg) and > 75 (1.2 kg),dry matter (17.63%), protein content of tuber (3.0 %) and protein yield (1152.30 kg ha-1). Higher values of economics viz., gross return (307280 ₹ ha-1), net return (218331 ₹ ha-1)and B:C ratio (2.45) in potato were observed with the application of 67% N through Urea and 33% N through FYM + PSB except cost of cultivation.
