Abstract:
A field experiment on Effect of different Nitrogen levels on the growth, yield and quality of potato (Solanum tuberosum L.) Varieties was conducted during rabi season 2022 at the Poly house, School of Agriculture, ITM University Gwalior (M.P.). The experiment was laid out in a Factorial randomized block design with 12 treatment combinations, which includes four Nitrogen Levels (viz., N₁-0 kg N ha^-1, N₂-100 kg N ha^-1, N₃-140 kg N ha^-1 and N₄-180 kg N ha^-1), three different varieties (viz., V₁-Kufri Pushkar, V₂-Kufri Jyoti V₃-Pushkar) and each treatment were replicated thrice. The soil of the experimental field was Sandy loam in texture with a medium in available Nitrogen (198.6), low in available Phosphorous (15.85) and High in available Potassium (229.6) and low in Organic Carbon (0.44). The result of the experiment revealed that an increase in the application of Nitrogen and varieties had significantly increased the growth, yield and economics of viz., plant population, plant height (cm), No. of leaves per plant, No. of haulms, Fresh weight of haulms (g), Dry weight of haulms, Tuber yield, Grade wise number of tubers (small, medium and large), and economics of potato, the application of 180 kg N ha^-1 with Pushkar varieties was at par on application of 140 kg N ha^-1 with Kufri Jyoti and application of 0 kg N ha^-1 and with Kufri Pushkar were found significant with this treatment. Economics viz., Total cost of cultivation, Gross return, Net return and B:C Ratio were significantly higher with nitrogen (140 kg ha^-1) with Kufri Jyoti.
