The "System of Rice Intensification"(SRI) represents a sustainable alternative to improve household yields and incomes. This study aimed to evaluate the yields and the profitability of the SRI and the Traditional Practices (TP) in Ziguinchor district, Senegal. A directed sampling based on criteria for selecting the system used and the cultivated varieties common to both systems was applied to collect the yield parameters and yields of paddy rice. Thus, 18 producers in the Badiate, Essyl, and Fanda sites were selected, nine per system and four 1 m2 yield squares were installed in each selected producer plot. A total of 72 yield squares, 36 per system, were installed, and an individual questionnaire was randomly administered to 55 producers using at least one of the systems to collect data on rice production and costs. The yield parameters including the number of fertile tillers per m2, the number of spikes, the weight of the 1000 grains are significantly higher (p<0.05) in the SRI including yield compared to the traditional system. Transplanting density and plant duration are higher in TP (26±5.6 plants/m2 and 26 days) than in SRI (16±0.4 plants/m2 and 16 days). The lower the transplanting density, the higher the yield parameters and the yield. The economic profitability, determined based on the benefit/cost ratio, is higher in SRI (1.5) than in TP (1.2). The SRI required a lot of technicality in its implementation and generated more cost of production. However, SRI was more productive and economically more profitable than the traditional system.

Agricultural Innovations

The System of Rice Intensification (SRI). developed in Madagascar some 25 years ago. is gaining increasing credence and momentum as probably 500.000 farmers in more than 20 countries are now using its methods to raise their rice. production -- while also reducing their use of external inputs and production costs. Rather than focus on the innovation itself, this paper will introduce SRI only briefly, focusing instead on the transnational system for innovation that has emerged in response to this agronomic opportunity that can be particularly beneficial for resource-limited households. Within SRI's conceptual and practical framework. farmers have devised many innovations. These are the focus of a parallel paper written for this workshop. That paper considers how farmers have made the original SRI methodology less labor-intensive (even labor-saving). and how they have extended methods devised for irrigated rice production both to unirrigated (rainfed) areas for growing rice and to other crops beyond rice. This paper is concerned with what can be considered as a de facto 'system of innovation' that surrounds and has accelerated the spread of SRI worldwide. SRI has differed from most other agricultural innovations in the extent to which farmers have voluntarily invested their own time and resources in taking SRI to peers as an impressive example of farmer-to-farmer extension. Also. innovative alliances have formed among diverse persons and organizations to disseminate and adjust the methodology. thereby supporting the spread of this innovation even despite resistance from some established institutions.

Use Efficiency

To meet the rising demand for rice, the staple food in Assam, the production of rice has to be increased by many folds. Considering the shrinkage of agricultural lands, productivity increase is the only way out to increase the production. System of Rice Intensification (SRI) is reported to enhance rice yield to considerable extent. However, the acceptability of the method by the tradition rice growers of the state is a matter of concern. Further, the resource use status of SRI is yet to be studied systematically in Assam. The present study on resource use in SRI has shown that the resources used in SRI need to be increased for enhanced rice production the state. Awaring the farmers about SRI and imparting proper training on SRI would certainly help the farmers to increase their rice production to make them rice secured.

The System of Rice Intensification (SRI), assembled in Madagascar over a 20-year period and gaining applicationinternationally since 2000, enables farmers to raise their irrigated rice production substantially just by making changes in theway they manage their plants, soil, water and nutrients, rather than by increasing inputs such as fertilizer, water oragrochemicals. Getting more output with less cost enhances profitability. This result is quite unprecedented, as discussed inpaper accompanying this one. SRI is not considered by its proponents as a technology; and by not presenting it to farmers asa set technology, this opens SRI up to many adaptations and innovations by farmer-users, who often but not always arecollaborating with NGO or government staff in a collaborative manner. This paper reports on a number of the innovations thathave been made in SRI practices, demonstrating bothfarmer capabilities and the advantages of engagingfarmers as partnersin an ongoing process of participatory development. The companion paper which considers SRI as a system for innovationoffers a more 'macro' view of SRI spread that complements this more 'micro' perspective.

Paddy Cultivation

The System of Rice Intensification (SRI) developed in Madagascar in 1980s is a revolutionary new idea for paddycultivation to increase yields with reduced external resources. Basic idea of SRI originally proposed (Basic SRI) is to applycombination of (a) transplanting of young seedlings with wider spacing and (b) intermittent irrigation during vegetativegrowth period Further, application of organic fertilizers without use chemicals has practiced as "Organic SRI" as an idealapproach to improve soil and to produce high quality rice. Over the past fIVe years, a Japan-funded irrigation project inEastern Indonesia executing by the Directorate General of Water Resources, the Ministry of Public Works has introduced SRIand assessed it's potential to reduce demandfor irrigation water while rewardingfarmers with higher production and incomes.This paper reports on on-farm comparative evaluations conducted over 9 seasons between 2002 and 2006 across 8 provincesunder DISIMP. It summarizes the results of 12,133 comparison trials that covered a total area of 9,429 hectares. Averageyield increase was 78% (3.3 tlha) with reductions of 40% in water use, 50% in fertilizer applications, and 20% in the costs ofproduction. As a conclusion, SRI practices can achieve significantly higher output of rice with a reduction in inputs, enhancingsimultaneously the productivity of the resources (land, labor, water and capital) used in irrigated rice production. Theeconomic attractiveness of SRI methods is very great, giving farmers strong incentive to accept water-saving as new norm forirrigated rice production.

Method Of Production

Some studies consider the System of Rice Intensification (SRI) method of rice production as more profitable than the Conventional method. Others, however, claim that there is no significant difference in yields between the two methods. The mixed representation of the economic value of the two methods of rice production by various authorities demands an empirical examination of the profitability of the two methods in Ghana. The study was, therefore, designed to identify which of the two methods of rice production is more profitable in Ghana. Two-stage sampling technique was used to select 220 farmers, comprising 110 farmers under each of the two methods of rice production which are predominant in Ejura-Sekyedumase Municipality and Sekyere East District of the Ashanti Region of Ghana. The data collected from farmers were summarized using descriptive statistics including arithmetic mean, standard deviation, minimum, maximum, frequencies and percentages. Gross margin and gross profit ratio were used to estimate profitability per acre of rice production under each method. The study revealed that, while farmers under the SRI method obtain GH¢60.68 for every GH¢100.00 sale of rice, farmers under the conventional method obtained GH¢44.04 per every GH¢100.00. The study, therefore, concludes that SRI method of rice production, though a little more costly, is more profitable resulting from a higher yield brought on by the adoption of best agronomic practices associated with the method. Based on the empirical results, the study recommends for the promotion of the System of Rice Intensification method of production in Ghana through awareness creation, extension services and training.
