What is SRI?
The System of Rice Intensification (SRI) was developed as a set of insights and practices that change the management of plants, soil, water and nutrients used in growing irrigated rice. These concepts and practices can be adapted for growing rice that is unirrigated or rainfed as well as other crops. SRI methods, by promoting growth of more productive and robust plants: Give higher yield — more tons of rice per hectare or per acre, Require less seed and less water — because plant populations are reduced, and paddy fields are not kept continuously flooded, Do not require purchase of external inputs – – since chemical fertilizer or agrochemical protection are not necessary, although they can be used with the other practices, and Do not require the purchase of new seeds – – since practically all rice varieties give higher yield with these methods, though some high-yielding varieties respond better than others. SRI methods are particularly accessible to and beneficial for the poor, who n
