Effect of critical limit of saline water irrigation in suitable rice (Oryza sativa L.) varieties

The pot experiments were conducted in Complete Randomized Design (CRD) with five replications at Wire net house, Department of Crop Physiology CSAUAT Kanpur, during Kharif seasons in the year 2022-23 and 2023-24. The objective of investigation way to study the effect of Salinity water irrigation with various levels (Five level of Saline T0. (Control), T1. ECiw 3(dSm-1), T2. ECiw 6(dSm-1), T3. ECiw 9(dSm-1), T4. ECiw 12(dSm-1), and Five variety on Pant-24, Pusa Basmati-1509, Sampurna (KP)-108, Narendra-2065, CSR- 46 plants traits i.e. physiological, phenological biochemical, yield and its components of Rice. The results indicated that application of recorded higher value of plant height, dry matter accumulation (g), number of panicle plant-1, number of grain plant-1, biological yield, 1000 seeds weight (g) and ultimately higher grain yield (g) plant-1 as compared to all other corresponding tested treatments. Further, these treatment ECiw 3(dSm-1) significantly maximum days for their phenological stages i.e., days of heading, anthesis and 75% flowering and days of physiological maturity as compared to all other treatments. Based on overall relative performance proved to be more beneficial with ECiw 3(dSm-1) it was concluded that were found to be better perform with respect of grain yield and other studied traits as compared to other treatment.
