Impact Analysis of System of Rice Intensification in Farmers Field

Abstract

Rice (Oryza sativa) is the principal food for more than 50% people and contributes about one-fifth to the total calories consumption of the world. The statistics showed that during the crop year 2016-17 india produced 110.15 million metric tonnes of milled rice from 43.19 million ha area, making the country the world’s second largest producer of rice. To meet the food and nutritional requirement, India alone would need about 156 metric tonne of rice by 2030 at an annual increment of 3 metric tonnes in the current rice production. There are several constraints to achieve desired potential of rice but in SRI methods help increase fields by over 50% while using 40% less water than conventional method. The SRI methods increase yield the productivity of water since yield can double or more with only half as much water, the productivity of water in greatly increased this is especially important in countries or places where water is becoming scarcer.
