Abstract This paper assesses the relative advantage of drought-tolerant (DT) maize, conditional on drought severity, using an unbalanced panel of 4 years of on-farm yield trials and high-resolution precipitation data (10-day measurements at a 0.05° resolution) in Malawi, Zambia, Mozambique and Zimbabwe. Under rain-fed conditions, DT maize yield exceeds that of other varieties: 7 per cent higher yields on average and 15 per cent higher yields under moderate drought stress. While this contrasts with higher estimates measured in controlled trials, it nonetheless represents an economically significant advantage. This study further measures heterogeneity in the relative advantage conditional using conditional quantile analysis.

Soybean is a drought tolerant crop which can grow from low to medium altitudes. In the lowland areas of North-Western Tigray the growing of leguminous crop is very low. To introduce soybean commodity in North-western Tigray, demonstration of improved soybean varieties were conducted in 2018/19. The trail was conducted at Tahtay Adyabo and Tselemti Districts that have a potential for growing the soybean. It was conducted by selecting three Kebelles from the districts. A total of 35 farmers were involved in the intervention. The necessary training was given to the participant farmers and experts. Following this improved seed of Awassa-95 and Gizo varieties at Tahtay Adyabo Districts, and Wegayen and Gizo seed at Tselemti District were offered to participant farmers. Each farmer have been planted a plot size of 0.02 ha for each of the two varieties. The descriptive result shows, Awassa-95 soybean variety has given significantly higher yield at Tahtay Adyabo as compared to Gizo variety. The variety was gave an average yield of 1067 kg/ha and 570 kg/ha respectively Awassa-95 and Gizo varieties. On the other hand an average yield of 1231 kg/ha and 1052 kg/ha, respectively was obtained for Gizo and Wegayen varieties at Tselemti District. This shows that Tselemti District is more better for the cropping of Gizo variety. Moreover, the improved soybean verities (Gizo at Tselemti district and Awassa-95 at Tahtay Adyabo district) were found to be early maturing and best option to moisture stressed areas for the society protein source. Based on the result it is recommended to be popularize Awassa-95 soybean variety at Tahtay Adyabo District and Gizao soybean varieties at Tselemti District to large farmers. Therefore, the research center and the office of agriculture and rural development of the Districts to be popularized the varieties to large number farmers of the areas.

Majority of the rural households in Kenya depend on agriculture as a source of food and livelihood. Agricultural productivity has been declining due to many factors resulting in increased food insecurity in the country. Consequently, there is a renewed interest in promoting drought-tolerant crops such as sorghum which thrives in the arid and semiarid lands of the developing world. However, performance of sorghum production among the smallholder farmers has still remained low. This study was thus carried out to identify factors that influence technical efficiency of sorghum production among smallholder farmers in Machakos and Makindu districts of the lower eastern Kenya. Collected data on farm and farmer characteristics were analysed by use of descriptive statistics and Tobit model. Result highlights show that technical efficiency was influenced positively by formal education level of the household, experience in sorghum farming, membership in farmers associations, use of hired labour, production advice, and use of manure. Surprisingly household size, meant to enhance labour, had a negative influence. To increase technical efficiency, efforts should focus on improving information flows on agronomic practices. Farmers should also be encouraged to form and actively participate in various farmers associations, which enhance learning and pooling of labour resources, hence improving technical efficiency.

from International Centre for Agricultural Research in the Dry Areas (ICARDA) including some advanced lines from Bangladesh Institute of Nuclear Agriculture in 2006. During Preliminary Yield Trial, the genotype LG-208 produced 18.62% and 29.47% higher seed yield than the check variety BARI Masur-5 at Ishurdi and Magura respectively. Through advanced yield trials, regional yield trials, on-station and on-farm trials from 2010-11 to 2015-16, it was found that exotic germplasm LG-208 showed better performance than check (BARI Masur-5). Genotype LG-208 had significantly highest seed setting and harvest index under 20% polyethylene glycol (PEG) induced drought and considered as the drought tolerant which showed similar performance with field trials in drought-prone areas (Chapainawabganj and Rajshahi). Based on the superior performance of exotic germplasm LG-208 line, BINA has decided with the National Seed Board (NSB) of Bangladesh to register this line as a high yielding drought tolerant lentil variety, named as Binamasur-10 in 2016.

Three varieties of groundnut were used to assess the drought tolerance and high yielding potential. Groundnut (Arachis hypogaea L.) is an important oil seed crop mainly grown under rainfed situation. Erratic rainfall and frequent drought during the crop growth period, groundnut yields are generally low under rainfed conditions. Drought during critical crop growth stages is crucial for loss in yield of groundnut varieties. But tolerant genotypes may give better yield due to maintenance of physiological responses that were triggered during drought. On Farm Trials was conducted by Krishi Vigyan Kendra, Hansroever campus, Perambalur district in Tamilnadu, India to assess suitable drought tolerant and high yielding groundnut variety in terms of yield, acceptability and adoption potential during rabi 2018-19 in Perambalur district, India. Three varieties of groundnut were used to assess the drought tolerance and high yielding potential viz., Dharani, Co7 and TMV 7. The study revealed that Dharani recorded higher pod yield (2402 kg ha-1), higher number of pods plant-1 (26) and optimum plant population (26.3 plants m-2) as compared to farmers practice. The groundnut variety Dharani resulted in the highest shelling percentage (75%), while the lowest was registered with TMV 7. Gross and net returns were ` 115324 and ` 66593 ha-1, respectively by cultivating Dharani as against ` 87523 and ` 41550 ha-1 in the check variety. Dharani and Co7 would be a better option forrainfed cultivation in Perambalur district.

Climate Change Adaptation Strategies

Climate change continues to hamper crop-based systems across sub-Sahara Africa. Adaptation strategies prove to be effective at improving production and enhancing livelihoods of farm households. This study employs Cost-Benefit Analysis (CBA) to assess the perceived economic profitability of adopting various on-farm climate change adaptation strategies among farmers in Zabzugu and South Tongu districts in the north and south of Ghana. A simple random sampling approach was used to select 300 farmers who had previously benefited from climate change projects. Major strategies adopted in both districts were: changing of planting dates, planting early maturing varieties, row planting, seed refilling and planting drought tolerant varieties. Adoption intensity was high in Zabzugu district compared to the South Tongu District. Generally, the adoption of each strategy was perceived to be profitable since the estimated average benefits outweighed the average costs. However, the most profitable strategies were strip cropping, repeated sowing, refilling, zero tillage and row planting. Less profitable strategies included land rotation, mixed farming, early planting, tractor ploughing and “A-frame” contour farming. Among others, drought tolerant varieties of rice, maize and soybeans, as well as zero tillage, repeated sowing and strip cropping, should be promoted and farmers encouraged to adopt these practices for enhanced benefits.
