Assessment of Stress Tolerant Rice Varieties under Rain Fed Condition in North Eastern Ghat of Odisha

Abstract

A field experiment was conducted during kharif 2019 at NICRA villages viz. Nada, Chikili and Chopara of Krishi Vigyan Kendra, Ganjam1 through technology demonstration to analyse the performance of stress tolerant rice varieties under rainfed condition. Three different drought tolerant rice varieties i.e. MTU-1010, Sahabhagidhan and Swarna Shreya with ten replications were taken in random block design with improved package of practices compared to farmers’ practice. The results of technology demonstration revealed that growing of Swarna Shreya recorded higher growth parameters compared to other treatments with ten days delayed maturity. Improved practice of Swarna Shreya (T3) recorded higher number of filled grains panicle-1 (135.4±5.41), spikelet fertility (95.0±0.33 %), panicle length (24.8±1.45 cm) and 1000 grain weight (25.7±0.52 g) compared to other two treatments. Significantly higher grain yield (3588±169.5 kg   ha-1) and straw yield (7591±236.9 kg ha-1) were recorded compared to farmers’ practice (2632±125.1 kg ha-1 and 5934±366.4 kg ha-1, respectively). Swarna Shreya recorded higher gross return (Rs 67037±2980.2 ha-1), net return (Rs 37037±2980.2 ha-1), B: C ratio (2.23±0.20) and profitability (Rs. 101.5±8.16 ha-1 days) with as compared to farmers’ practice of growing MTU 1010.
