Description Climate change induced higher temperatures will increase crops’ water requirements. Every 10°C increase
in mean temperature, results in 7% decline in the yield of rice crop. Hence, there is a need to develop water
saving technologies in rice which consumes more than 50% of the total irrigation water in agriculture. System
of Rice Intensification (SRI) is one such water saving rice production technology. Experiments were conducted
at different locations in India including research farm of Directorate of Rice Research (DRR), Hyderabad, during
2005-10 to assess the potential of SRI in comparison to normal transplanting/Standard Planting (NTP/SP) under
flooded condition. SRI recorded higher grain yield (6 to 65% over NTP) at majority of locations. Long term studies
clearly indicated that grain yield was significantly higher (12-23% and 4-35% over NTP in Kharif and Rabi seasons,
respectively) in SRI (with organic+inorganic fertilizers) while the SRI (with100% organic manures), recorded higher
yield (4-34%) over NTP only in the Rabi seasons. Even though, SRI resulted in higher productivity, the available
nutrient status in soil was marginally higher (10, 42 and 13% over NTP for N, P and K, respectively) at the end of
four seasons. There was a reduction in the incidence of pests in SRI and the relative abundance of plant parasitic
nematodes was low in SRI as compared to the NTP. About 31% and 37% saving in irrigation water was observed
during Kharif and Rabi seasons, respectively in both methods of SRI cultivation over NTP. SRI performed well and
consistently reduced requirement of inputs such as seed and water in different soil conditions. SRI method, using
less water for rice production can help in overcoming water shortage in future and it can also make water available
for growing other crops thus promoting crop diversification
