Effect of Water Management, Weed and Integrated Nutrient Management on Yieldof Potato (Solanum tuberosum)

A field experiment was conducted at IGKV, Raipur (C.G) during rabi 2010–11 and 2011–12. The soil of experimental site was clayloam in texture, neutral in soil reaction. The climate of the region is sub humid with an average annual rainfall of 12001400 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, tuberizationefficiency) 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 potatocrop. 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.
