SYSTEMATIC RICE INTENSIFICATION

SRI (systematic rice intensification) is a proven methodology for comprehensively managing resources and changing the way land, seeds, water, nutrients and human labour are used. SRI is not a fixed package of technical specifications, but a system of production with four main components, viz., soil fertility management, planting method, weed control and water (irrigation) management. It is a newer production method that is relatively cost effective and use water more productively. It becomes imperative against the backdrop of the deepening water crisis and dwindling productivity under the inundation method of rice cultivation. In addition to the water shortage, non-availability of labour on time is also increasing the cost of production, forcing farmers to give up rice cultivation citing low productivity and high labour costs as reasons.

SRI emerged in the 1980’s as a synthesis of locally advantageous rice production practices encountered in Madagascar by Fr Henri de Laulanie, a Jesuit Priest who had been working there since 1961. But, it is Dr. Norman Uphoff from Cornell International Institute for Food and Agriculture, Ithaca, USA, who had brought this method to the notice of outside world in the late 1990s. Today SRI is being adopted in many states in India and the response from farmers has been overwhelming seeing the benefits of the method, notwithstanding the constraints.

At present times SRI also has some practical problems. The cono weeder which is an important tool in the cultivation practices is too heavy for pulling in the fields by the farmers. The other problem area is transplanting the seedlings from the nursery to the main field, which is quite labour intensive.
