Abstract : A field experiment was conducted at IGKV, Raipur (C.G) during rabi 2010-11. The soil of experimental site was clay loam in texture, neutral in soil reaction. The climate of the region is sub humid with an average annual rainfall of 1200-1400 mm. Results revealed that drip irrigation 100 % or 125 % of OPE proved comparable and gave higher growth parameters, yield attributes (number of stolons plant-1, number of tubers plant-1, fresh weight, dry weight of tubers, tuberization efficiency) and total tuber yield of potato crop as compared to furrow irrigation. The herbicide Metribuzin (500 g a.i. ha-1PE) proved better among other weed management practices recorded the maximum growth parameters, yield attributes (number of stolons plant-1, number of tubers plant-1, fresh weight, dry weight of tubers, tuberization efficiency) and total tuber yield of potato crop. Application of 75% N inorganic fertilizer + 25 % N organic (Poultry manure) + PSB + Azotobactor produced significantly highest growth parameters, yield attributes (number of stolons plant-1, number of tubers plant-1, fresh weight & dry weight of tubers, tuberization efficiency) and total tuber yield.
