Written by: Devotha B. Mosha, Gilead Mlay, Colin Poulton and Amrita Saha
This paper discusses System of Rice Intensification (SRI) interventions and its potential effects on paddy yield and commercialisation in Mngeta division, Kilombero district in Morogoro region, Tanzania. SRI is an innovative agroecological methodology that aims to improve yields and farmers’ profits by creating the most suitable environment for the rice plant to grow. It comprises the precise set of cultivation practices specifically required for careful management of biophysical needs of the rice plant for producing high yields. To assess the effects, we compare between trained and non-trained farmers, as well as between farmers who are members of SRI associations and non-SRI members, on aspects of adoption of SRI interventions, paddy productivity and yields. In turn, the effects of SRI is evaluated in terms of its influence on rice yield per hectare and commercialisation at household level.
