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 optimize doses of Zn, Fe and Mn in different combinations and its effect on yield contributing characters, seed recovery and quality in rice (Oryza sativa L.) varieties 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 (%), seedling vigour index and electrical conductivity. The experiment was laid out in the 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%) with three varieties viz. NDR 97, NDR359 and BPT 5204. The result revealed that inoculation of 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 among doses of foliar spray of micronutrient, Zn, Fe and Mn @ 0.75%, 1.50% & 0.75% may be utilized in rice for seed production as it produced higher seed yield, maintained the seed recovery and other yield contributing quality of seeds.
