“…In the SRI practice, rice production was significantly higher with reduced inputs (Sato and Uphoff, 2007). Increased family labor increased the yield of SRI (Nguyen and Hung, 2022). Commercial rice production in Nepal is thought to have begun about 500 years ago (Agrama et al, 2010).…”

System of Rice Intensification (SRI technology) increases rice yields while requiring less water and other inputs. It involves the use of specific management strategies that, when used together, provide rice plants with better-growing conditions than those grown using traditional methods, especially in the root zone. An SRI experiment was conducted from February 27, 2022, to July 11, 2022, in rice farmers' fields in Buddhabhumi Municipality, Nepal, using different spacing and seedlings. Spring rice was grown using the SRI with a variety of seeding and plant spacing. The experiment consisted of three plant spacings: 20 × 20, 30 × 30, and 40 × 40 cm, and two seeding groups: regular seeding and pregerminated seedlings. Characteristics were counted, including the number of tillers per mound, leaves, plant height, tillers per square meter, grain yield, and 1000 kernel weight. The result shows that the 20 cm × 20 cm spacing increased tillers per square meter. The spacing also resulted in much higher grain production of 4.29337 Mt/ha. The 30 × 30 cm plot had the tallest plants at 78.10 cm, much higher than the other plots. Similar crops produced significantly more tillers per mound (22.5) when planted at 40 × 40 cm spacing. Since the crops were planted at 40 × 40 cm, the spacing produced significantly more tillers per mound (22.57) and leaves per mound (73.54). Spacing did not affect test weight, nor did the type of seedlings used.

Rice cultivation plays a vital role in the Southeast Asian (SEA) economy, but it poses environmental challenges and contributes a significant amount of greenhouse gas emissions. To address these concerns, sustainable agricultural practices (SAPs) for rice production have been introduced to mitigate the environmental impact of rice production while fostering economic and social sustainability. However, the adoption of these practices remains limited, highlighting the need for a critical review of existing literature to gain deeper insights into the factors influencing farmers’ adoption of these practices in SEA countries. This review analyzed 39 manuscripts to assess the current state of SAPs for rice cultivation in SEA. We found that socio-demographic variables and farm management variables were frequently examined in these studies, with varying levels of significance. Economic and institutional variables were moderately studied and tended to have more significant findings. There is a noticeable research gap regarding behavioral factors, emphasizing the need for further investigation in SEA. Furthermore, the findings underscore the importance of conducting additional research to develop effective monetary and non-monetary incentives and explore methodologies to address the gaps in understanding farmers’ trade-offs and preferences among different SAPs. These efforts are crucial for promoting the widespread adoption of SAPs in rice cultivation.
