“…These results are in agreement with findings of Nayak et al, (1998) and Barison (2002). Maximum grain yield achieved in SRI was due to higher leaf area index (LAI) and light interception at wider spacing between plants gained from open plant structure.…”

“…An additional important benefit of aerobic soil conditions is the development of larger root systems, as reported by Barison and Uphoff (2011), Mishra and Salokhe (2011) and Thakur et al (2011). This gives rice plants larger exploitable root zones in the soil, which under anaerobic conditions are further restricted by the hard pan needed to hold water for maintaining flooding.…”

Much of the focus of agricultural improvement efforts in recent decades has been on modifying crops' genetic potential more than on improving cropping practices and production systems. Certainly, this genocentric approach has made significant contributions to food production in certain parts of the world under the banner of ''the Green Revolution.'' Yields have been raised substantially through varietal improvements and the increased use of inputs, including energy, agrochemicals, and delivering more water to crops through irrigation technology. In the past two decades, however, gains from this strategy have decelerated, with increasing economic and environmental costs of this input-dependent approach. Accordingly, there is reason to consider what can be accomplished by making optimizing changes in crops' growing environments both above ground and, especially, below ground. The System of Rice Intensification (SRI) developed in Madagascar has been showing that, by modifying crop, soil, water and nutrient management, it can under most of the circumstances evaluated thus far raise of the productivity of land, water, seeds, capital, and labor used for irrigated rice production. This article summarizes and reflects on the evidence provided in the preceding articles in this special issue. It draws on the scientific evaluations and field experience from Asia, Africa, and Latin America to offer some conclusions about the methodology known as SRI. Since this methodology is still evolving, no final assessment is possible. Much more research and evaluation remain to be done, and there will be further modifications and refinements since making adaptations to local conditions is regarded as intrinsic to the methodology. Further improvements in SRI will come from both researchers and farmers, with the latter considered as partners rather than simply adopters. This is consistent with SRI's representing a paradigm shift more than a fixed technology. The article identifies a number of areas for additional research that can probably improve factor productivity still further.

“…Similarly, planting younger seedlings at wider spacing might have resulted in more root growth which might have penetrated deep into the soil to exploit more nutrients and water resulting in increased number of tillers, shoot and dry matter production. Higher shoot dry matter production with transplanting of younger seedlings was also reported by [16][17][18][19] Increase in number of tillers per unit area by planting younger seedlings was observed by a number of researchers [20-22]. There were far more tillers in non-flooded plots than flooded plots [23].…”

Different fertilizer treatments were applied to local rice varieties under SRI (system of rice intensification) against conventional management practices at ARI Mingora Swat during 2010-2011 using RCBD with split plot arrangement. The results show that under the SRI practices, rice varieties performed well and the plant parameters such as number of panicles plant -1 , number of tillers plant -1 , plant height, panicle length, grains panicle -1, biological yield, grain yield, harvest index, 1000-grain weight and plant dry weight were significantly improved under the SRI method as compared to traditional method. Combined fertilizers (NPK and Zn) enhanced rice yield significantly, which can be attributed to positive effect on yield components. Rice variety, Fakhre Malakand out performed under SRI management practices with combined application of fertilizers. It was concluded that SRI is the best management practice for rice cultivation as water availability is most likely to be a major constraint in the immediate future.
