Abstract Future rice systems will need to produce more grain while minimizing the environmental impact. A key question is how to orient agricultural research & development (R&D) programs at national to global scales to maximize the return on investment. Here we assess yield gap and resource-use efficiency (including water, pesticides, nitrogen, labor, and energy) across 32 rice cropping systems, together accounting for 88% of global rice production. We show that achieving high yields and high resource-use efficiencies are not conflicting goals. Most cropping systems have room for increasing yield, resource-use efficiency, or both. In aggregate, current total rice production of these systems can be increased by 36%, and excess nitrogen almost eliminated, by focusing on a relatively small number of cropping systems with large yield gaps and/or poor resource-use efficiencies. This study provides essential strategic insight for prioritizing national and global agricultural R&D investments to ensure adequate rice supply while minimizing negative environmental impact in coming decades.

This study examined the resource-use efficiency of smallholder rice production farmers in Federal Capital Territory, Nigeria. The problem of resource use among small-scale rice production farmers is preponderance in the country. Hence, the study investigated the drivers of the problem in the Federal Capital Territory of Nigeria. Specifically, the study was designed to determine the factors influencing the resource-use efficiency of the respondents. A multi-stage sampling technique was used to select a total sample size of one hundred and seventy-five (175) rice farmers in Federal Capital Territory, Nigeria. Seven estimators such as age, household size, farming experience, educational level, extension services, access to credit, and off-farm income in the Probit model were found statistically significant. Results show that the probability of resource use efficiency of inputs used by the farmers increases with age, farm size, household size, educational level, extension services, experiences in farming, access to credits, but decreases where they have off-farm income. Mc Fadden Pseudo-R2 gives 0.6772, and the Probit model explains a significant proportion of the variations in smallholder farmers' resource use. The study concluded that the socio-economic variables in the model play an important role in influencing resource use efficiency. The study recommends that government agencies and donors should provide simplified, accessible and obtainable credits and grants to existing and prospective rice farmers in order to sustain the current giant stride in rice production in the country.

This study evaluated resources–use efficiency among rice farmers in Katcha Local Government Area (LGA) of Niger State, Nigeria. The specific objectives are to; describe socio-economic characteristics of the rice farmers, determine the production inputs influencing rice output, resource–use efficiency in rice production and identify constraints associated with rice production. Two-stage sampling procedure was used for selection of 88 rice farmers on which questionnaire was administered. Data collected was analyzed using descriptive statistics, multiple regression model and resource – use efficiency ratio. Results of the analysis revealed that 76.2% of the respondents were males, while 93.2% were married. The mean age, farming experience and household size of the respondents was 46 years, 23 years and 11 people, respectively. The multiple regression analysis result showed that double-log with R2 value of 0.9571 was chosen as lead equation and farmland (4.83, p<0.01), labour (2.34, p<0.05), seeds (4.04, p<0.01) and fertilizer (3.46, p<0.01) had positive coefficients and statistically significant. The efficiency ratio of resources-use in rice production showed that farm size (15.71) was under-utilized, while labour (0.001), seeds (0.554) and fertilizer (0.056) were over-utilized. Major constraints of rice production identified were inadequate training on resources usage (94.3%), followed by problem of pest and diseases (84.1%) and problem of storage facilities (81.8%). These problems ranked 1st, 2nd and 3rd, respectively. In conclusion, the production inputs were not efficiently utilized by the rice farmers. It was therefore recommended that, extension agents should educate farmers about relevant farm management skills in order to optimally utilize resources in rice production.

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.
