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.

Evaluation of Rice Varieties under Different Systems of Cultivation for Central Telangana Zone

“…Lower grain yield might be due to lower dry matter production, number of tillers, test weight, panicle weight, number of filled grains panicle -1 and panicle length. The results are in conformity with the findings of Kumhar et al [23], Harish et al [15], Chandrika et al [18], Dileep et al [25], Sharath Chandra et al [32], Anil and Siddi [19], Mangaraj et al [26].…”

“…The difference in number of effective tillers among the genotypes might be due to their genetic potential, number of tillers, uptake of nutrients by varieties and crop weed competition ability of variety at all crop growth stages. The results are in close conformity by Kumhar et al [23], Chowhan et al [24], Dileep et al [25], and Mangaraj et al [26].…”

“…Higher straw yield might be due to adequate supply of resources which results higher dry matter production, more number of tillers, maximum leaf area and better portioning of photosynthates resulting maximum straw yield. The results are in line with the findings of Kumhar et al [16], Harish et al [34], Chandrika et al [18], Dileep et al [25], Sharath Chandra et al [32], Anil and Siddi [19] and Mangaraj et al [26].…”

Efficacy of Drought Tolerant Rice Variety Swarna Shreya in North-eastern Ghat Zone of Odisha through Frontline Demonstration

“…Along with improvement in yield and net return farmers preferenece or adoption of this variety has increased by 53 times (Table 5.) over initial year of demonstration both within and outside the village [17]. This might be due to high yield and the incent price farmer getting during drought condition and upland area.…”

Performance of Climate Smart Rice Varieties in Dibrugarh District of Assam, India

“…Besides flood sometimes the state facing drought like situation during this time. Dibrugarh is one of the districtof Assam which is affected by flood in most of the times and also facing drought to some extent [5,6]. Mostly long duration local varieties of winter rice are grown in Assam as well as in Dibrugarh district and only 10-15 percent area is devoted to high yielding varieties (HYV), as a result, the productivity of rice becomes low.…”
