SRI Method Of Paddy Cultivation

System of Rice Intensification (SRI) is under evaluation in 29 countries at present, where it has been shown that yields can be enhanced by suitably modifying certain management practices such as controlled supply of water, planting of younger seedlings and providing wider spacing. This method of cultivation is said to promote greater root growth and higher soil biological activity in the rhizosphere. The benefits of SRI include increased yield (20-25%), a reduction in seed requirement (75%), water saving (45-50%), strong and profuse root system and tillering resulting in lodging resistance, improving soil health, reduction in pests, diseases, grain shattering and unfilled grains. The System of Rice Intensification improves yields with less water, less seed, and less chemical inputs than most conventional methods of rice cultivation. This means that the returns on inputs are higher, making the method potentially more profitable than most of the traditional methods.
