The demand for rice in Eastern and Southern Africa is rapidly increasing because of changes in consumer preferences and urbanization. However, local rice production lags behind consumption, mainly due to low yield levels. In order to set priorities for research and development aimed at improving rice productivity, there is a need to characterize the rice production environments, to quantify rice yield gaps—that is, the difference between average on‐farm yield and the best farmers’ yield—and to identify causes of yield gaps. Such information will help identifying and targeting technologies to alleviate the main constraints, and consequently to reduce existing yield gaps. Yield gap surveys were conducted on 357 rice farms at eight sites (19–50 farmers per site) across five rice‐producing countries in Eastern and Southern Africa—that is Ethiopia, Madagascar, Rwanda, Tanzania and Uganda—for one or two years (2012–13) to collect both quantitative and qualitative data at field and farm level. Average farm yields measured at the eight sites ranged from 1.8 to 4.3 t/ha and the average yield gap ranged from 0.8 to 3.4 t/ha. Across rice‐growing environments, major causes for yield variability were straw management, weeding frequency, growth duration of the variety, weed cover, fertilizer (mineral and organic) application frequency, levelling and iron toxicity. Land levelling increased the yield by 0.74 t/ha, bird control increased the yield by 1.44 t/ha, and sub‐optimal management of weeds reduced the yield by 3.6 to 4.4 t/ha. There is great potential to reduce the current rice yield gap in ESA, by focusing on improvements of those crop management practices that address the main site‐specific causes for sub‐optimal yields.

“…O arroz é alimento básico para metade da população mundial, pois supre cerca de 20% das necessidades nutricionais, o que o torna essencial para a segurança alimentar e nutricional (PRASAD et al, 2017). O Brasil é responsável por 77,45% da produção de arroz no bloco Mercosul (CONAB, 2019).…”

“…Only China has a 20% paddy-field and 31% of all world rice production. Many studies have been described that among other crops, rice is the most and ancient food source for people as well, [1]. Consequently, each kind of stress to this plant can have a dangerous impact on rice production and ultimately result in huge economic losses.…”

“…While rice is a highly adaptable crop that can as result be grown in a wide variety of environmental and climatic conditions, which is commonly undesirable for the growth of other crops around the globe. Although there has been reported a great increase in rice production during recent years, it still needs to be developed and improved the yielding capacity of its through stress tolerance mechanisms [1,2]. Biochar addition to effectiveness in soil ameliorate and plant productivity, it also by having a great influence on abiotic stresses that can play a key role in adapting (acclimatize) rice crop through the promoting of plant growth regulators roles.…”

Rice as a sensitive crop that usually affected by many harmful environmental stresses. Numerous policies are followed to increase plant growth-tolerance under abiotic-stresses in various plant species. The attempts to improve crop tolerance against abiotic stresses via common breeding method are needed to follow a long-term, and may also be non-affordable, these are due to the existing genetic variability of the plant. Current review analysis existing knowledge gaps, challenges, and opportunities in the biochar application as a beneficial and pyrogenic-C, material. Consequently, a review of the literature with a high focusing on the multiple beneficial effects of using biochar on tolerance and productivity of rice in abiotic stresses is needed. This review provides a summary of those efforts that would be beneficial in reducing inconvenienced abiotic-stresses, and also how using biochar could increase rice tolerance and production through the supporting of plant growth regulator's roles. Accordantly, present review findings showed that biochar is a great amendment and consisting of principally organic rich-C matter, which has multiple benefits on improving soil physicochemical and biological properties as well as increasing rice tolerance and its productivity through enhancing plant hormones roles under abiotic stressed conditions (heat/cold temperature, drought, salinity, heavy metal, and climate change stresses). Nevertheless, it is anticipated that further researches on the benefits of biochar will increase the comprehension of interactions between biochar and plant growth hormones, to accelerate our attempts for improving rice tolerance and productivity, under abiotic-stress conditions.
