Advance Agro- Techniques for Yield Efficiency and Economics of Potato (Solanum tuberosum) Crop for Chhattisgarh Plains

The experiment has been conducted on the experimental field of Indira Gandhi Krishi Vishwavidyalaya, Raipur under split-split plot design along with three replications in the year 2010-11 and 2011-12 during the Rabi season in potato crops (Solanum tuberosum). Irrigation (three treatments) as a main plot, weed management (four treatments) as a sub plot and Integrated Nutrient Management (INM) (four treatments) has been taken as sub-sub plot in the spacing of 60x20cm on the variety Chipsona-2. Total combined plots were 3x4x4x3=144. The parameters have been taken: growth parameter i.e. CGR, tuberization efficiency, weed parameters: weed index, weed control efficiency, nutrient uptake, yield and yield Attributes i.e. No. of Stolen/plant, no. of tubers/plants, tuber yield/ha and economics. The result revealed that the significantly higher CGR, tuberization efficiency, nutrient uptake by plants, yield has been found under the 75% N (inorganic) + 25% N (poultry manure) + PSB + Azotobactor in sub-sub plot, the herbicide metribuzin found most efficient and effective than the other herbicide i.e. under sub plot. Drip irrigation has been found significant than other method of Irrigation; on the different parameter of growth, yield and yield attributes as well. The recommendation of the study is potato crop performed better under drip irrigation100 and 125 % of OPE, 75% N (inorganic) + 25% N (poultry manure) + PSB + Azotobactor with application of metribuzin (500g a.i ha-1) herbicide with the spacing of 60x20 cm for the plains of Chhattisgarh.
