“…The shoot count in this study was in agreement with Yoseph and Sorsa (2014) who reported counts of 3, 2.8, and 2.7 for three improved sorghum varieties at flowering growth stage. There was a significant accretion in number of shoots from PS2 to PS3 with no significant accretion thereafter.…”

Mwangi PG, Gachuiri CK, Mbugua PN. 2017. Effect of growth stage on fodder yield and quality of dual purpose sorghum. Trop Drylands 1: 100-104. Improved Dual Purpose Sorghum (IDPS) (Sorghum bicolor-Var Ikinyaruka) were yielded at six physiological growth stages to evaluate the impact of growth stage on crop and feed quality. Six treatments based on sorghum growth’s physiological stage were randomly administered to the plot in a block and replicated three times. The treatments were IDPS yielded at bloom stage (PS1), soft dough stage (PS2), hard dough stage (PS3), physiological maturity stage (stalks with grains), (PS4), physiological maturity stage (stalks without grains) (PS5), and 1 month post grain reap (PS6). The parameters monitored were Dry Matter (DM) crop, Crude Protein (CP), Neutral Detergent fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL), In vitro Dry Matter Digestibility (IVDMD) and shoot count. The highest DM crop (18.0 ton/ha) was achieved at PS4 secernated with 8.69, 12.75, 16.27 17.04 and 13.04 ton/ha for PS1, PS2, PS3, PS5 and PS6, respectively. CP reduced with maturity from 8.6 at PS1 to 7.98, 7.96, 7.61, and 6.77 to 6.72 at PS2, PS3, PS4, PS5 and PS6 respectively. NDF and ADF at PS1, PS2, PS3, PS4, PS5 and PS6 were 54.4, 60.8, 65.71, 65.93, 66.73 70.3 and 27.93, 35.96, 41.98, 41.97, 42.04, 46.05 respectively. ADL was 3.44, 5.03, 7.38, 7.39, 7.42, and 8.3 for PS1, PS2, PS3, PS4, PS5 and PS6 respectively. Highest fodder IVDMD of 60.72 was at PS1 secernated with 60.12, 54.73, 53.82, 53.56 and 45.75 achieved at PS2, PS3, PS4, PS5 and PS6 respectively. The PS3 growth stage yielded in fodder material with highest nutritive value while highest fodder yields were achieved at PS4. Reaping at PS5 supplied both fodder and grains for livestock and human consumption respectively. It was proven that crop and quality of IDPS were affected by age at reaping time.

“…This was confirmed by the existing correlation between growing season rainfall and annual actual yield of the region for the period 2003-17. The increase in actual yield could be the result of change in the adoption of improved agronomic measures in the region during the stated period although it is found at its early stage (Shiferaw and Yoseph, 2014;Yoseph and Sorsa, 2014). Higher inter-annual variability of Melkam and Teshale Y w was observed at Benatsemay than Jinka for both models and this could be attributed to differences in edaphic and climatic conditions of the area.…”

Model-based yield gap analysis and constraints of rainfed sorghum production in Southwest Ethiopia

et al. 2020

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.

“…In response to this Jinka agricultural research center has conducted sorghum varieties and agronomic management experiments at Nyangatom and Dasenech woreda of the south Omo zone (2019 and 2020) cropping seasons and Melkam sorghum variety and its agronomic management which gave higher yield (3.3 t•ha -1 to 5.4 t•ha -1 ) were recommended for further production in the area. And other previous works by different scholars (Tekle and Zemach [4] ; Fuad et al [5] ; Abebe et al, [6] ; Melese [7] ) focused on performance evaluation of sorghum varieties in arid and semiarid areas to enhance productivity. However, less emphasis has been given to commercializing sorghum production as compared to other cash crops like cotton and banana.…”

Cluster-based improved sorghum (Melkam variety) production and commercialization was demonstrated in Nyanghtom Woreda of the South Omo Zone for one year (2021) to improve agro-pastoralists’ awareness, enhance the adaptation of full-package production technologies, and increase the economic visibility of improved sorghum cultivation. The production was started in a single kebele with a 7-hectare area of coverage. Twenty-five purposively selected direct beneficiaries and twenty-five randomly selected indirect beneficiaries from a neighbor were involved in the production. Direct beneficiaries cultivated sorghum on 0.28 hectares of land. At various stages of crop growth, monitoring, evaluation, and fieldwork were done by both beneficiaries and indirect beneficiaries. Face-to-face interviews with sorghum producers and non-producers were undertaken. Simple descriptive statistics were used to examine quantitative data, like grain yield, whereas the Likert scale was used for qualitative data such as agro-pastoralists perceptions. The result revealed that 30 quintal sorghum grain yield per hectare was obtained from improved sorghum (Melkam variety). The average return obtained from the sale of sorghum grain per hectare was 120,144 ETB. Agropastoralists’ perception result revealed that the “Melkam” variety is a higher yielder, and early matured as compared to local. Therefore, cluster-based sorghum production should be promoted for local sorghum growers in order to improve sorghum production sustainability and also seed system should take into account the provision of improved Melkam variety seed.
