SRI (System of Rice Intensification) is an improved method of rice cultivation originally developed in Madagascar. SRI principles focus on sustainably producing more with less resources.   SRI may be defined as an improved method of rice cultivation where rice is grown under intermittent aerobic conditions, transplanting younger single seedlings at wider spacing, using more organic matter and less water, thus sustainably achieving higher yields from stronger plants utilizing less resources.

Cono weeder demnstration SRI farm

SRI is a work in progress and  there isn’t a standard package of practices  that is universal to all regions. Farmers need to implement what is known and experiment on how to make it better.

 Experiments conducted with Rice during season I (Kharif 2010):             YIELD DATA

At SriAg Farms, we selected Samba Masuri variety (BPT 5204) for all of our trials. our experimental design included the following treatments:

Treatment 1: Performance of SRI paddy under 25×25 cm spacing vs.  25x 12.5 cm spacing

Treatment 2: Performance of SRI paddy under Organic fertilizers vs. Inorganic fertilizers

Treatment 3: Performance of SRI paddy  in clay loam soils vs.  sandy loam soils

Treatment 4: Performance of paddy under SRI method vs. Traditional method

SRI paddy fields were irrigated following alternate wetting and drying cycles. Traditional paddy fields were flood irrigated. Phenominal Yields were achieved under SRI method compared to traditional method.
