A field experiment was conducted during kharif 2022, to study the evaluation of rice genotypes under direct seeded condition. The experiment was laid down in randomized block design (RBD) with eleven rice genotypes viz., SYE-68-15-34-31-12-35-13, SYE-930-8-25, SYE-94-32-9-17, SYE-335-4-37-9, SYE-309-39-13-18-5-23-20, SYE-1635-40-15-4-9-44-18, PKV-HMT (CH), PDKV Tilak (CH), PKV Ganesh (CH), PDKV Kisan (CH), Awishkar (CH) and three replications at research farm of Botany Section College of Agriculture, Nagpur. Observations about biochemical parameters like leaf chlorophyll, nitrogen content and amylose content were also estimated. Observations on yield and yield contributing parameters. Significantly enhance biochemical parameters like chlorophyll and Nitrogen content in leaves and amylose content in seed were also enhanced check PKV-Ganesh, PKV-HMT, PDKV Tilak, PDKV Kisan and Awishkar.

Rice, biochemical parameters, yield

The check PKV Ganesh significantly showed significant enhancement in morpho-physiological parameters viz., plant height, number of tillers hill-1, days to flower initiation, days to 50% flowering, days to maturity, leaf area plant-1, leaf area index, total dry weight, RGR and NAR. Similarly biochemical parameters like chlorophyll and Nitrogen content in leaves and amylose content in seed were also enhanced check PKV-Ganesh, PKV-HMT, PDKV Tilak, PDKV Kisan and Awishkar. Yield and yield attributing parameters, grain yield kg/plot and grain yield ha-1 (kg) were also showed significant increment by genotypes SYE-309-39-13-18-5-23-20 and SYE-94-32-9-17.
