“…The results confirm high yielding attribute of improved pigeon peas (Kwena et al, 2018;Olubayo et al, 2007). Early harvests helps households' get through the hunger period before harvest when the previous year's grain supplies have been exhausted.…”

“…About 94 percent of adopters and 70 percent of non-adopters perceived that improved peas had drought tolerance, 92 percent adopters and 75percent non-adopters perceived early maturing attribute, 80 percent and 54 percent perceived that the peas had pest and disease tolerance. The increase in atmospheric temperature with reduced, variable rainfall causes both biotic and abiotic stress to pigeon peas in semi-arid Kenya (Kwena et al, 2018) and perception and /or potentials to avert the adverse effects through production of improved crop varieties fosters adoption to increase productivity. The results confirms effort of agricultural researcher to mitigate effects of climate change to increase productivity within a finite natural resource basis and maintain food security in the face of population growth and climate change (Miriti et al, 2012) About 12percent of the households sampled had grown KARI mbaazi1 on average acreage 0.91 acres (std.…”

“…Soil and water conservation was practiced in 74 percent and 67 percent in the two groups correspondingly. Surprisingly less than 5 percent of the farmers used manure on farm indicating limited application of soil fertility enhancing practices in pigeon pea production despite high levels of soil degradation in Machakos County (Kwena et al, 2018).…”

“…Kwena et al, (2018) reports that improved pigeon pea have potential to yield of 3 tons per ha per year relative to the indigenous that yield just a third portraying its suitability for enhancing smallholder farming resilience to the shocks of climate change. As droughts become common and dry lands expand due to climate change, pigeon pea remains an important crop for food and nutritional security and a source of income in semi-arid Kenya (Cheboi et al, 2016;Gok, 2016;Kwena et al, 2018). The peas are protein rich which are crucial for nutrition security especially because about 55% of the rural population in SEK are poor and unlikely to afford sufficient animal proteins (GoK, 2015).…”

“…The roots of the crop fix nitrogen into the soil and release soil-bound phosphorus, thus ameliorating the nitrogen and phosphorus deficiencies that typify most soils in the dry areas in Kenya (Kwena et al, 2019;Odeny, 2007). The crop's tolerance to both biotic and abiotic stress makes it adaptable to semi-arid areas that are perennially water stressed (Kwena et al, 2018). The growing demand for the crop in both local and export market provides a source of food and income to the majority smallholder producers (Makelo et al, 2013).…”

Purpose: Improved pigeon pea varieties were promoted in semi-arid areas of Kenya to improve smallholder pigeon pea production systems resilience to climate change. However, the impact of adoption is unknown. This study was carried out to evaluate the impact of adoption on farming households’ net farm returns in semi-arid South Eastern Kenya in the context of adaptation to climate change. The objectives were to (i)describe farmer’s perceptions on production of improved varieties of pigeon peas as an adaptation strategy to climate change, (ii) evaluate the impact of the adoption on household’s net returns. Propensity score matching approach was used to assess the impact of the adoption. Methodology: The study used cross sectional data gathered through household survey to evaluate the impact of adoption on farming households’ net farm returns in semi-arid South Eastern Kenya in the context of adaptation to climate change.. The study was conducted in semi-arid zones of Machakos County in South Eastern Kenya (SEK) namely Masinga, Mavoko and Mwala Wards. The areas were purposively selected for semi-arid semi-arid climatic conditions and dominant pigeon pea production.The study adopts the counterfactual approach and propensity score matching method to evaluate the impact of adopting improved pigeon peas on household net farm income. Data was analyzed using STATA 13.0 statistical package. Findings: The results showed that 33 percent of the sampled households had adopted production of improved pigeon peas and they perceived adoption of the technology as an adaptation strategy to climate change viewed through tolerance to drought, pest and diseases, increased crop yield and shortened crop growth period. Improved pigeon peas significantly increased farmers’ net income, the adopter got a net farm income of KES 30,710 per acre per year that was KES 18, 631 more than non-adopting households. Unique contribution to theory, practice and policy: The study recommends that County Governments facilitate farmers to produce pigeon pea seeds through improved access to seed and linkage to reliable market for their farm produce to increase their farm income.

Background: Sweet potato producers in Kenya practice either sole cropping of or relay cropping and rarely do intercropping which aims at maximizing on time and space. Objective. To assess the relative performance of sweet potato under various cropping systems. Methodology: This study was conducted in Katumani, Kenya for two seasons; 2018/2019 and 2019/2020. The treatments comprised of sole cropping of Kabode, sole cropping of Bungoma, Kabode + common bean, Bungoma + common bean, and sole cropping of common beans (Mwezi mbili) were laid out in a randomized complete block design (RCBD) in 3 replications. Monocropped sweet potato and beans served as the control treatment. Weather data, leaf area, leaf area index, vine length, and percent canopy cover were collected throughout the cropping period. The data were analysed by a two-way ANOVA at 0.05% significance level followed by a Pearson’s correlation analysis on the extent to which length of vines, percent canopy cover, leaf area index, and weather parameters; ETo, aridity index, and rainfall influenced the attained tuber yields. Results: Intercropping significantly (p < 0.05) reduced sweet potato yields of Kabode and Bungoma varieties by 19.3% and 44%, respectively. Monocropped Kabode yielded 31.4 t ha-1, significantly (p< 0.05) higher than monocropped Bungoma with 23.9 t ha-1 whereas their common bean intercrops yielded 26.2 t ha-1 and 18.1 t ha-1,respectively. Correlation analysis showed that rainfall, ETo, LAI, vine length, and percent canopy cover negatively affected tuber yields. Implication: Land equivalent ratio revealed that intercropping sweet potato varieties with common beans was biologically efficient and that the percentage of the land saved averagely ranged from 8% to 33%. More studies should be conducted to determine the extent of sweet potato allelopathy on companion crops and nutrient use under intercropping systems. Conclusion: Yield stability analysis showed that orange-fleshed Kabode was the most stable variety across seasons to be grown in Katumani.
