Abstract: The present investigation were conducted during Kharif 2015 and 2016 at Student Instructional Farm and lab experiments were carried out in Seed Testing Laboratory of Seed Technology Section, N. D. University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) India with objective of the study was to optimization of seed technological parameters and micronutrients supplementation on yield contributing characters, seed recovery and quality in rice (Oryza sativa L.) for yield contributing traits and seed quality parameters i.e. days to 50% flowering, no of tillers per plant, productive tillers per hill, Plant height (cm), panicle length, Days to maturity, spikelet fertility, harvest index, seed recovery, seed yield (q/ha), 1000 seed weight (g), germination (%), vigour index and electrical conductivity. The experiment was laid out in Split Plot Design with three replications keeping two methods of transplanting viz. C1 (Normal method) and C2 (SRI method) in the main plot and three foliar spray of micronutrient doses viz. M1 (Zn, Fe and Mn @0.25%, 0.50%&0.25%), M2 (Zn, Fe and Mn @0.50%, 1.00%&0.50%) and M3 (Zn, Fe and Mn @0.75%, 1.50%&0.75%) in sub plot. The two transplanting spacing viz. S1 (15×20 cm) and (25×25 cm) were also applied in the sub plots with three genotype viz. NDR 97, NDR359 and BPT 5204. The result revealed that inoculation of transplanting method, spacing and foliar spray of micronutrients doses significantly improved days to 50% flowering, no. of tillers per plant, productive tillers per hill, Plant height (cm), panicle length, Days to maturity, spikelet fertility, harvest index, seed recovery, seed yield (q/ha), 1000 seed weight (g), germination (%), vigour index and reduce electrical conductivity. Overall the treatment of findings revealed that rice crop should be transplanted on 25×25 cm under SRI method with the foliar spray application of Zn, Fe and Mn @0.75%, 1.50%&0.75%, for obtaining high seed yield potential of the variety producing good quality seeds.
