The main object of this book is to provide the knowledge to the poor marginal Rice growing farmers of West Bengal as Rice is the most important cereal crop in this state. But increasing in cost of cultivation in terms of fertilizer, pesticide as well as agriculture-labour the net profit gain of the poor rice growers are gradually decreasing. This book is providing the information regarding System of Rice Intensification (SRI) as an new alternative source of rice cultivation with increasing productivity and profit and minimizing the environmental hazard.

One of the major constraints in achieving high productivity goals is low fertility of Indian soils due to the poor management under so called intensive cultivation practices. In both agriculturally- advanced irrigation ecosystem as well as the less endowed rainfed region, nutrient replenishment through fertilizers and manures remains far below the crop removal, thus causing the mining of native nutrient reserve over years. Wide spread deficiencies of N, P, K, S, Zn and B have emerged in intensively cultivated areas and significant crop responses to application of these nutrients are reported....
