  2. 2. IntroductionThe System of Rice Intensification (SRI) is a “set of insights and practices that change the management of plants, soil, water and nutrients used in growing irrigated rice.” SRI methods, promote the growth of more productive and robust plants.More simply; SRI is a package of practices especially developed to improve the productivity of rice.SRI involves intermittent wetting and drying of paddies as well as specific soil and agronomic management practices.. pdfMachine - is a pdf writer that produces quality PDF files with ease!

  3. 3. Advantages of SRI? Increases rice yield per drop of water, per kg of seed and Why SRI?  Consuption, demand and prices for fertilizers (highest yield 22.4 rice increasing  The shortage of water (climate MT per ha in India). change)  Shortage of land suited for rice Tolerable to flood, lodging and production  The Total of 0.17 million tones grain drought. food deficit as compared to its Very suitable for organic requirement in Nepal.  About 50% farmers have land production. RCT holding less than 0.5 ha.  Farmers and scientist have challenge SRI is based on the local to develop new alternatives to resources, no need to increase the sustainable purchase any extra external productivity, in context of climate inputs, although they can be changing.  SRI would be the best alternatives. used with the other practices. pdfMachine - is a pdf writer that produces quality PDF files with ease!

  11. 11. Conclusions & Recomendations The experiments clearly revealed that younger seedlings transplanted in 8 days old with a plant density of 25 cm × 25 cm with SRI technique resulted into maximum production with good economic returns of rice. Thus the SRI technique can be extended to a larger rice growing area consisting of small landholding farmers and thereby maximizing total production of rice, ultimately contributing to national food security. Our NARS should recognized the technology and endorse the technology by doing test, verification, and making it more suitable to the farmers of wide climate range in Nepal. pdfMachine - is a pdf writer that produces quality PDF files with ease!
