A field experiment was conducted at IGKV, Raipur (C.G) during rabi 2010–11 and 2011–12, to evaluate the suitable irrigation schedule, weed management and nutrient management. 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 minimum total weed density and total weed dry weight was found under drip irrigation (100% of OPE) at all stages during both the years and on mean basis, yield attributes and total tuber yield of potato crop was significantly maximum under drip irrigation (125% of OPE) as compared to furrow irrigation. The herbicide Metribuzin (500 g a.i. ha⁻¹PE) proved better among other weed management practices recorded minimum total weed density and total weed dry weight was found at all stages and the maximum yield attributes and total tuber yield of potato crop. Application of 75% N inorganic fertilizer + 25% N organic (Poultry manure) + PSB + Azotobactor was found non significant to weed control while produced significantly highest yield attributes and total tuber yield.
