The system of rice intensification has come as a great boon to farmers who would apply lesser water to the water intensive crops and get better yields. Rice yields increase in the range of 7 to 15 tones per hectare, depending upon the region. The system is now being practiced in limited areas of a few states in India. It is likely to gain wider acceptances. The system of rice intensification achieves improvements in yields and factor productivity by changing some of the plant, soil, water and nutrient management practices. It promotes greater root growth that is easily verifiable and more soil biological activity. Interestingly, the system of rice intensification does not depend upon purchased externals like chemical fertilizers and pesticides. Instead, it increases the productivity of the land, labour, water and capital devoted to irrigated rice production by capitalizing
on existing genetic potential by biological process, particularly the soil.
Quality of land is a significant factor in the effectiveness of rice intensification process.
