Impact of different irrigation techniques and nitrogen regimes on quality parameters of potato (Solanum tuberosum L.)

The present study was conducted at Research Cum Instructional Farm, College of Agriculture, IGKV, Raipur (C.G.) during rabi season 2022-23 and 2023-24. The experiment was conducted using variety Kufri Khyati under split plot design with three replications, keeping five irrigation levels i.e. I₁: 75% CPE with drip, I₂: 100% CPE with drip, I₃: 125% CPE with drip, I₄: 150% CPE with drip and I₅: Furrow irrigation as a main plot and four nitrogen doses i.e. N₁: 90 kg N ha^-1, N₂: 120 kg N ha^-1, N₃: 150 kg N ha^-1 and N₄: 180 kg N ha^-1 as sub plot. The quality parameters like maximum tuber dry matter content (20.82% and 21.09%), haulm dry matter content (18.35% and 19.27%) and total soluble solid (7.23% and 6.86%) were observed higher under treatment I₄N₄ (150% CPE with drip + 180 kg N ha^-1) as comparison to other treatments. However minimum quality attributes was recorded under combination of furrow irrigation and lowest regimes of nitrogen.
