“…Such soil texture difference has a significant effect on availability of water and crop yield when water is the yield-limiting factor (Silungwe et al, 2019). Similarly, the Y w of the crop showed some differences with respect to the same yield level of other regions of Ethiopia where the potential yield of the crop was determined based on field experiment (5.15 t/ha) (Kinfe and Tesfaye, 2018) and crop model (2.8-10.2 t/ha) (Van Bussel et al, 2015). Divergence of potential yield from field experiment and crop model is expected since under field conditions maintaining all management practices to their best level and controlling all biotic and abiotic factors throughout the growing season are quite difficult.…”

“…Even though sorghum is one of most important crops in a harsh environment, the adverse weather conditions particularly rainfall during the growing season penalize farmers yield (Singh et al, 2014;Msongaleli et al, 2017;Zewdu et al, 2020). There has been a consistent effort on developing improved varieties in Ethiopia but they do have little adoption by the farmers due to poor extension service, bird attack specially for early maturing varieties, higher post-harvest loss due to pest and lower biomass as compared to the land races (Beshir and Sime, 2013;Kinfe and Tesfaye, 2018). Additionally, economical problem related to lower market prices of grain as compared to other cereals and higher input prices such as chemical fertilizers demotivated farmers to use the improved agronomic practices during sorghum production (Tonitto and Ricker-Gilbert, 2016).…”

For ensuring food demand of the fast growing population in developing countries, quantification of crop yield gaps and exploring production constraints are very crucial. Sorghum is one of the most important climate change resilient crops in the rainfed farming systems of semi-arid tropics. However, there is little information about yield gaps and production constraints. This study aimed at analysing existing yield gaps and exploring major constraints of sorghum production in Southwest Ethiopia. A crop simulation model approach using AquaCrop and DSSAT was used to estimate potential yield and analyse the yield gaps. Model calibration and evaluation was performed using data from field experiments conducted in 2018 and 2019. Sorghum production constraints were assessed using a survey. The actual and water-limited yield of sorghum ranged from 0.58 to 2.51 and 3.6 to 6.47 t/ha, respectively for the period 2003–17. The regional yield gaps of sorghum for the targeted period were 3.02–3.95 t/ha with a mean value of 3.51 t/ha. Majority of respondent farmers considered seasonal rainfall risk (98%), poor soil fertility (86%), lack of improved varieties (78%) and inadequate weed management (56%) as major factors responsible for the existing yield gaps. The mean exploitable yield gap (2.5 t/ha) between water-limited and actual yield showed the level of existing opportunity for improvement in the actual productivity of sorghum. The gaps also call for introduction of proper interventions such as adoption of improved varieties, planting date adjustment, conservation tillage, fertilizer application and on time weed management.

“…While we estimated an average water-limited potential yield for maize of 6.1 t ha −1 , the average maize water-limited potential yield was 6.0 t ha −1 for the 2015/2016 seasons [21]. For sorghum, Kinfe and Tesfaye [67] found an average potential yield of 3.9 t ha −1 in the moist lowlands of the country. The global GAEZ model approach at 5 arc minutes spatial resolution estimated the average maize and sorghum potentials to be 10.6 t ha −1 and 6 t ha −1 respectively for the Gambella region [68].…”

Land Use Scenarios and Their Effect on Potential Crop Production: The Case of Gambella Region, Ethiopia

2019

Agricultural intensification and cropland expansion are the key policies to increase food production in Ethiopia. Gambella is one of the regions in Ethiopia which is highly suitable for agriculture; however, the local people still face food shortages. We therefore investigated the potential for intensification and cropland expansion. In this study, we developed land use scenarios of agricultural intensification and expansion and analysed their effect on potential crop production in the region and estimated the population that could be nourished as a result. We distinguished between different degrees of intensification, ranging from low input rainfed to high input irrigated agriculture and different degrees of expansion, considering the best 30% or 50% of land to be utilized for expansion. While the results reveal that irrigation had almost no effect on potential yields, they also show that the potential calorie production in all scenarios far exceeds the current and possible future caloric requirements of Gambella’s population. For example, for the top 50% expansion scenario, calorie production increased by +428% for the low input and by +1092% for the high input scenarios. Thus, Gambella could nourish up to 21 million people and serve as a bread basket for the entire country, which could improve national food security.

“…Previous studies on sorghum in Ethiopia have much more concentrated on factors affecting adoption of improved sorghum, for example (Hailegebrial & Adane, 2018;Tsfaye, 2013;Mahdi et al, 2012;Kinfe, 2018;Salih et al,. 2018;Beyene et al, .2016) and genetic diversity of sorghum, for example (Olani,2017;Mugambi,2010;Tesfaye,2017).…”

The purpose of this study is to identify market participation of smallholder’s Sorghum producers in Moretna jiru district, central Ethiopia. Primary data was collected from 355 randomly selected smallholder farm households from three randomly selected kebeles in the district. The survey data was analyzed using descriptive statistics and econometrics model with probit and Tobit censored model. Results of the probit model analysis showed that output, farm size, extension contact and ownership of transport positive and significant role in households’ decision to participate in sorghum output sales at 1% level of significance; whereas, household income, off-farm income, access to credit and lack of information negatively at 1% and 10% level of significance. Results of Tobit censored analysis showed; extension contact, farm size, output and membership of farmer group have positive and significant role in the value of sorghum at 1% level of significance; while access to credit was found to have negative significant role at 5% level of significance. Farm size, output, extension contact and membership of farmer group was found to affect both households’ decisions to participate and intensity of participation in sorghum sales at 1% level of significance. Based on the findings there is a need to enhance the interaction between extension export and farmers and distribute trained extension exports in all kebeles by giving different trainings. ; and help the farmers improve land productivity, where possible, by intensifying farm practices through provision of sustainable and timely availability of inputs and management practices so as to generate surplus sorghum output and boost sales.
