RiceSystem of Rice Intensification Introduction
SRI Technology Uses - Less External Inputs In SRI Paddy Cultivation Less Seed (2kg/ac) is required and fewer plants per unit area (25x25cm) whre as in general Paddy Cultivation 20kg seed is required per acre. SRI requires less expenditure on fertilizers and plant protection chemicals. Root Growth In SRI System Rice Crop grows healthy in natural conditions and its root growth can be massive receives nutrients from deeper layers of the soil. 3 hills under conventional method required 28kg of force to be pulled up where as single SRI rice plants required 53kg for uprooting. SRI is initially labour intensive
SRI encourages rice plant to grow healthy with
Tillering is greatly increased
Because no set back due to early transplanting and no die back of roots. Maximum tillering occurs concurrently with panicle initiation. More filled grain per panicle and no lodging of crop.
Six Mechanisms and Processes for SRI
In SRI Cultivation 8 to 12 days old seedlings are planted. So root system grows well and gives 30 to 50 tillers. When all the 6 management practices are followed then per plant 50 to 100 tillers are produced and high yields can be realised. Nursery Management
