Title : Effects of Various Transplanting Dates and Genotypes on Growth and Yield of Basmati Rice (Oryza sativa L.) in Trans-Gangetic Plains of India

Abstract :

It is expected that environmental changes influence the growth and development of crop, and with this hypothesis, a field experiment was laid to investigate the impact of different dates of transplanting on various genotypes of basmati rice. Three genotypes of basmati rice i.e. CSR 30, Pusa Basmati (PB) 1121 and Haryana Basmati (HB) 2 were sown with three transplanting dates (June 25, July 10 and July 25) in the kharif season of 2015 and 2016 using. The experiment was designed in a split-plot layout with four replications, where dates of transplanting were allocated to the main plots and the genotypes to the subplots. The ANOVA table showed that the main effects of the dates of transplanting and the genotype are significant for nearly all the assessed characters. Significant interaction between the date of transplantation and the genotype were observed for number of effective tillers (NET), harvest index (HI) and straw yield (SY). The grain yield (GY) on first date of transplanting (25th June) showed significant incrememt by ~2.5 and ~17% relative to the second (10th July) and third date of transplanting (25th July), respectively. The findings of this study revealed that early transplanting enhanced positive effects on assessed characters of basmati rice. Further, correlation study has exhibited the positive and significant correlation (p≤0.05) of GY with NET, number of grains per panicle (NGPP), panicle length (PL), 1000-grain weight (GW) and HI.
