Evaluation of Seed Yield and Quality under Different Planting Systems in Rice (Oryza sativa. L)

Abstract

Out of different planting systems available in rice, various factors such as local conditions, water resources and labour availability decides the choice of planting. To study whether the large scale seed production can be taken under different popular planting systems without any compromise on seed quality is the need of the hour. The present experiment was conducted to understand the influence of different planting methods on seed yield and quality in rice. The experiment was carried out Kharif, 2022 with two rice varieties namely RNR 15048 and KNM 118. Each variety was sown separately in five different planting systems i.e., T1-Transplanting (Control), T2-Dry direct seeded rice, T3-Direct wet seeded rice, T4-Aerobic rice, T5-Drum seeded rice with three replications in the factorial randomised block design. The maximum seed yield of 7.6 t/ha was in aerobic planting system and the influence of seed quality parameters in different planting methods like germination, seedling vigour index-I and II, physical purity, field emergence, accelerated ageing test showed that aerobic system of planting has shown good quality with germination value of 97%, seedling vigour index-I of 2357.04, seedling vigour index-II of 1339.51, physical purity of 99.04%, seed reserve utilization with efficiency of 15.15, field emergence of 93.5% and when subjected to accelerated ageing under required conditions till 5th day the aerobic rice has shown 96% of germination. Among all the planting systems, aerobic rice has shown superior performance representing it’s role in the development of quality seed parameters.
