Title : Enhancing quality parameters of sesame and potato through organic and inorganic nutrient management practices in sesame -potato cropping sequence

Abstract :

The current study was conducted at the ICAR - CPRI-RS, Gwalior (M.P.) during the kharif and rabi seasons 2020-21 and 2021-22 on the quality parameters of sesame and potato crops in sesame – potato sequence as influenced by organic nutrient management. The experiment was designed having seven treatments in the Randomized Block Design (RBD) with four replications. The organic treatment comprised of crop residue @ 25 t ha-1 with bio-fertilizer (Azotobacter and PSB), FYM @25 t ha-1, vermicompost @7.5 t ha-1, neem cake @ 5 t ha-1 in different treatments including control, 100% RDF and INM (RDF+FYM). The result revealed that among all the organic manures, RDF and integrated treatments, oil content was non-significant but effect on protein content, protein and oil yields were found significant during both the years. Treatment T7 (100% RDF + FYM @ 25 tha-1) showed best results in quality parameters i.e., oil yield (454 and 427 kg ha-1), protein content (19.1 and 18.8%) and protein yield(180 and 163 kg ha-1)as compare to other treatments in sesame crop during 2020-21 and 2021-22. Application of 100% RDF NPK (inorganic practices) gave higher oil content (48.5 and 49.4%) during 2020-21 and 2021-22. Application of 100% RDF + FYM @ 25 t ha-1recorded higher starch content (14.17 and 14.01%), starch yield (1199.4 and 1257.4 kg ha-1) and protein yield (670.1 and 726.6 kg ha-1) but crop residue @ 25 t ha-1 + bio-fertilizer (Azotobacter + PSB, @ 1 l ha-1each respectively) procured the highest protein content (8.32 and 8.26%) in potato during both the years and other quality parameters i.e., tuber dry matter content, water % and true density % which were observed non-significant during both the years in potato crop.
