This article summarizes the evaluation of a new method for rice cultivation, the System of Rice Intensification (SRI), by a group of 90 rice farmers in Benin. Between August 2009 and June 2012, a series of tests were conducted in two rice ecosystems on 32 plots. This farmer-conducted research focused on the new methodology’s agronomic performance and its labor and seed requirements, also considering what would be the constraints on adoption. The trials showed that SRI methods could increase average yields under farmer conditions by 54 %, while reducing seed requirements by 87 % and shortening the growing season by 14 days. To achieve these benefits required an increase in the amount of labor, by 36 %. Producers participating in this evaluation concluded that SRI offers significant opportunities to increase their rice production, provided its methods are adapted to local conditions

Organic Farming System

Introduction of organic rice-based rice cultivation technology package through demplot is done in Subak Sungi 1 using ciherang variety. The number of farmers participating in demonstration plots in organic cultivation of paddy-based rice cultivation were 5 people, with age of farmers aged greater than 55 years occupying the highest percentage (45.45%), with elementary education level (72.75%), followed by high school education (18.25%), and junior high (9%). The average farmland area is 34.63 acres, with self-owned status (55,94%), status as penyakap 41,18% and rent status 2,88%. The farmers' response to the organic rice-based rice planting assessment is quite high, as evidenced by the evaluation that 100% of farmers participating in demonstration plots know and understand about organic rice system cultivation, and they agree to develop this cultivation system in the future. Demplot research results can increase the yield components and weight of dry grain harvest per hectare. Organic rice-based rice cultivation technology EVAGRO able to increase production of dry grain harvest significantly with a value of 6.8 tons / ha. There is a tendency of dry weight value of ciherang varieties of 6.8 tons / ha giving highest but not significantly different with PGPR organic based technology.

Many efforts are conducted to increase the fertilising efficiency, especially nitrogen in rice cultivation practices. This field experiment was conducted to evaluate the effect of zeolite on growth and production of lowland rice during rainy season in Badung, Bali. The experiment showed that fertilizer mixed with zeolite resulted in the same growth and productivity, although the fertilising doses was reduced. This means that zeolite incread fertilising efficiency in rice cultivation.

There is anecdotal evidence of the effectiveness of Extension and Advisory Service (EAS) agencies for strengthening innovation networks to adapt to extreme events that impact agricultural production and productivity. In Bangladesh, the Department of Agricultural Extension (DAE) is responsible for ensuring sustainable rice farming, which is damaged by flash flooding every year. This study investigates how EAS can strengthen farmers’ innovation networks by examining DAE’s efforts to adapt rice cultivation to flash flooding. Using surveys and interviews from farmers affiliated with DAE (DAE-farmers) and farmers independent of DAE (non-DAE farmers), the effectiveness of innovation networks was examined. One of the key findings of this paper is that DAE’s efforts to strengthen the innovation networks of farmers to adapt rice cultivation to flash flooding focused on the facilitation of the agronomic network development. The organization missed the opportunity to enable the harvesting networks’ efficacy. As the harvesting activities are highly exposed to flash flooding, the absence of adequate support from the DAE and timely updates of local weather and flash flooding information indicates that farmers are still at significant risk. This study also shows the value of including both formal (e.g., EAS agencies, research organizations) and informal actors (e.g., relatives, local input dealers) in the innovation network as a way of ensuring diversity of information access.
