Abstract: A field experiment was conducted during 2017-18 and 2018-19 at ICAR- CPRI-RS, Gwalior M.P. during kharif and rabi to judge the “effect of different cropping systems and fertility levels on quality and physiological parameters of potato”. The experiment was laid out in split-plot design with three replications. In main plots three cropping systems viz. M₁: Cowpea – Potato, M₂: Maize + Cowpea – Potato, M₃: Maize – Potato with five sub plots of fertility levels viz. F₁: 150% RDF, F₂: 125% RDF, F₃: 100% RDF, F₄: 75% RDF + 25% organic and F₅: 50% RDF + 50% organic replicate three times. Cowpea – potato based cropping system recorded maximum protein content in tuber viz. 7.55% on pooled basis, respectively as compare to other cropping systems. Maximum protein content in tuber 7.61% recorded by 75% RDF + 25% N through FYM. Cowpea – potato based cropping system recorded maximum starch content in tuber viz. 12.93% on pooled basis, respectively as compare to other cropping systems. Maximum starch content in tuber 13.62% recorded by 50% RDF + 50% N through FYM. Maize + Cowpea – potato based cropping system recorded maximum water content in tuber viz. 21.11% on pooled basis, respectively as compare to other cropping systems. Maximum water content in tuber 20.58% recorded by 100% RDF. At stage 0-30 DAP, 30-60 DAP and 60 to maturity stage absolute growth rate, crop growth rate, leaf area index and leaf area duration significantly were recorded higher under the cowpea-potato based cropping system. At 60 to maturity stage, 75% RDF + 25% N through FYM significant result of absolute growth rate, crop growth rate and leaf area index was found during both the years which was at par with 125% RDF. At 30, 60 and maturity stage cowpea-potato based cropping system recorded highest value of LAD at all the stages of crop growth, highest LAD was registered under (125% RDF).
