धान की सीधे बीज (डायरेक्ट सीडेड) से बुआई: पानी की खपत और श्रम को कम करने के लिए एक दृष्टिकोण In India, rice field covers an area of 43.94 million hectares (mha) with production of 106.54 mt and has the share of 21% in global rice production during 2013-14. Of the total rice area, 49.5% (22 mha) is irrigated, 13.5% (6 mha) is upland, and 32.4% (14.4 mha) is rainfed lowland. In Asia, 90% of fresh water has been exploited by agriculture and more than 50% is utilized to irrigate rice. More than 75% of the rice supply comes from 79 mha of irrigated land. Therefore, food security is challenged and threatened by declining water availability. By the end of 2025, 2 mha of dry season rice and 13 mha of wet season rice would suffer from “physical water scarcity” in Asia. On the other hand, 22 mha of irrigated dry season rice in South and Southeast Asia already experiencing “economic water scarcity”. Therefore, agriculture scientists looking for different approaches to reduce water use and increase the water use efficiency for rice production. An alternative approach to reduce water consumption and labour drudgery in rice cultivation is the concern. Direct seeded rice (DSR), helps farmers to earn more carbon credits than transplanted rice (TPR)...

चावल के सतत उत्पादन के लिए संसाधन संरक्षण प्रौद्योगिकियों Rice (Oryza sativa L.) is one of the most important staple food crops in the world. In Asia, more than two billion people are getting 60-70 percent of their energy requirement from rice and its derived products. In India, rice occupies an area of 44 million hectares with an average production of 90 million tonnes at productivity of 2.0 tonnes per hectare. It is estimated that 140 million tones of rice would require by 2025 in India. Therefore to sustain present food self-sufficiency and to meet future food requirement, India has to increase its rice productivity by 3 per cent per annum.   The present production trend showed decline in productivity, mostly because of imbalanced use of fertilizers and pesticides, over-exploitation of the natural resources, particularly water, deterioration in physical conditions of the soil and emergence of new bio-types of pests and diseases. These led to yield stagnation, causing concern about the future potential for productivity growth and long-term sustainability. Thus the major challenge before the researcher is to innovate appropriate technologies to produce more food from diminished land resources for the burgeoning population pressure and to improve as well as conserve the natural resources of small and marginal farmers who contribute the greatest in this...
