Abstract:
The experiment was conducted at Regional Agriculture Research Station, Karjat during kharif -2020, kharif-2021, rabi-20-21 and rabi-21-22 for the studies of morphological and physiological parameters rice genotypes under kharif and different sowing windows during rabi season in Konkan. The experiment was laid out with 40 early duration rice germplasms in Split Plot Design with three replications. The experiment consisted of two factors: Main plot - four date of sowing i.e. S1-24th MW, S2-48th MW, S3-50th MW, S4 - 52th MW and sub plot 40 rice genotypes (V1 to V40). From the data, it is revealed that Hira and OR-1516-1-5-A showed the shortest days to maturity, while Ratnagiri-6 and Ratnagiri-1 required the longest time. Sowing in the 50th meteorological week with Ratnagiri-5 resulted in a longer maturity period, whereas kharif sowing with Hira resulted in a shorter duration. Ratnagiri-5 and Ratnagiri-1 required the most extended time to mature.

Karjat-3 had a higher average growth rate.Sahyadri-2 displayed a higher relative growth rate and Phondaghat-1 demonstrated a higher net assimilation rate. Sowing in the 48th meteorological week with Hira resulted in a higher average growth rate, sowing in the 52th meteorological week with Ratnagiri-7 led to a higher relative growth rate, and sowing in the 50th meteorological week with Karjat-1 yielded a higher net assimilation rate.
Sahyadri-4 recorded significantly maximum grain yield per plant (24.62 g) which was at par with genotypeKarjat-3 (23.93g) over other genotypes. Kharif season (24th MW) with Sahyadri-4 recorded significantly higher grain yield per plant (22.86 g) which was superior over other treatment combinations during pooled mean.
