Production Technique of Paddy’s Value-Added Product Puffed Rice (Murmura / Murra) धान (ओराइजा सताइवा एल) सबसे महत्वपूर्ण खाद्य  प्रधान फसलों में से एक है जो दुनिया के कई हिस्सों में पोषक तत्वों का एक प्रमुख स्रोत है धान दूसरी सबसे बड़ी अनाज की फसल है यह घास परिवार (ग्रैमिनेसी) का सदस्य है, जो स्टार्चयुक्त बीज का उत्पादन करता है। चावल इन्सान की दैनिक भोजन में अपनी कुल कलोरी का ६०-७०% और प्रोटीन का एक तिहाई हिस्से की पूर्ति करने में योगदान करता है, चावल हमारे दैनिक भोजन में न केवल आहार के रूप में लिया जाया है बल्कि इसके अलवा चावल का प्रयोग नाश्ते के रूप में खाद्य पदार्थो में जैसे की मुर्रा, पोहा, चिवडा, लाइ इत्यादि के रूप में भी करते आ रहे है मुख्य भोजन के रूप में यह भारत की अर्थव्यवस्था में एक महत्वपूर्ण भूमिका निभाता है इसलिए कृषि नीति बनाने में एक केंद्रीय स्थान रखता है तथा  धान कई तरह के औद्योगिक उत्पाद जैसे कि चावल, राइस ब्रान ऑयल, मुर्रा, पोहा, लाइ  इत्यादि जैसी खाद्य पदार्थों की पूर्ति के लिए भी एक महत्वपूर्ण स्त्रोत है | चावल के मूल्य वर्धित उत्पाद: पफ्ड राईस (मुरमुरा / मुर्रा) पफ्ड राईस जिसे कुरमुरा, मुरमुरा, मुर्रा / मूरी के नाम से भी जाना जाता है, खाने में बहुत हल्का वजन और कुरकुरा होता है। खाने में...

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...

धान के ब्रीडर सीड या प्रजनक बीज का उत्पादन Breeder seed is seed or vegetative propagating material directly controlled by the originating or sponsoring plant breeder of the breeding programme or institution and / or seed whose production is personally supervised by a qualified plant breeder and which provides the source for the initial and recurring increase of Foundation seed.  Concept of breeder seed The breeder seed is the first stage seed in the generation system of seed production. The breeder seed provides the source of the first and the subsequent increase of foundation seeds. This seed is produced by or under the direct control of the sponsoring plant breeder. Production techniques of breeder seed of paddy 1.    Land selection: The breeder seed should be grown in such a field where earlier no rice crop was grown or if grown same variety and same class should be grown to avoid volunteer plants. 2.    Land preparation: The field should be prepared well with proper puddling, perfect levelling for uniform growth and maturity. 3.    Seed Source: Clean, healthy, and treated seeds are sown in seed beds 4.    Seed Rate: 10-15 Kg seed is sufficient for one acre based on seed type and test weight. 5.    Spacing:  15 x 20 or 15 x 15 cm2 (row x plant), depending on the season and variety. Keep 40 cm spacing after every 8 rows/...

पूर्वी भारत के असि‍ंचि‍त क्षेत्रों में सूखा प्रवृत्त ईकोसि‍स्‍टम के लिए चावल की किस्में। Rice (Oryza sativa L.) , the staple food of more than three billion people in the world, is cultivated under diverse ecosystems ranging from irrigated to rainfed upland to rainfed lowland to deep water. In India, the total area under rainfed lowland and upland rice is 14.4 and 6.3 million ha, respectively. The frequent occurrence of abiotic stresses such as drought has been identified as the key to the low productivity of rice in rainfed ecosystems, particularly in eastern region of India. The eastern region comprises of Bihar, Eastern Uttar Pradesh, Odisha, West Bengal Jharkhand, Chhattisgarh and plains of Assam, represents 21.85% geographical area of the country and supports to 33.64% of country production. Most of the current high-yielding varieties of rice grown in rainfed areas are varieties bred for irrigated ecosystems and they are highly susceptible to water scarcity (drought) condition. Keeping this fact in view, there is urgent need to disseminate and adoption of high yielding drought tolerant varieties to achieve food self sufficiency at national level from eastern region. Water requirement of puddled irrigated and rainfed upland rice Studies across the country indicate that puddled irrigated rice requires about 900-2250 mm of water (average 1500 mm) depending on the...
