Abstract:
A field experiment entitled “Effect of organic manures on Potato yield, nutrientss uptake and soil fertility” was conducted at Main Experiment Station Vegetable Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during rabi season of 2018-19. The soil of the experimental field was silt loam texture, having pH 8.1, EC (dSm-1) 0.23, organic carbon (gkg-1) 3.1, available N 140kg/h, P 15.2kg/h, K 240kg/h, bacterial population 25.5 cfu/g soil and fulgal population 14.7 cfu/g soil. Field trial was laid out in RBD with three replication, having 7 number of treatments viz. T1-Control, T2 FYM 30 t/ha + PSB, T3-Poultry manures 5t/ha + PSB, T4-Vermicompost 7.5 t/ha + PSB, T5-FYM 10 t/ha + Poultry manures 1.7 t/ha + Vermicompost + 2.5 t/ha + PSB, T6-Recommended dose of nitrogen (150 kg) in which 67% N through inorganic and 33% N through FYM + PSB, T7- Farmer practices – FYM 15t/ha + Vermicompost 1t/ha + PSB. Growth and yield of potato and nutrients uptake were found significantly superior inT6 treatment (where organic and inorganic N applied in the ratio of 1:2) over control. Maximum potato tubers yield (38.41 t/ha), nutrients uptake N (184.4 kg/ha), P (34.6 kg/ha) and K (185.2 kg/ha) were recorded in T6 while B:C ratio (2.47) was observed under T3 treatment (where poultry manure 5t/ha + PSB applied). Better soil health recorded with T5 treatment (where FYM 10 t/ha + Poultry manure 1.7 t/ha + Vermicompost 2.5 t/ha + PSB applied).
