“…The findings of this study are congruent with an earlier work (37), who found that raising the legume planting ratio lowered the grain yield of the main crop due to plant growth resource competition between component crops. Furthermore, the current findings are consistent with an earlier report in which it was found that cereal grain yields fell as the seed rate of legume crops increased (14). It was also showed that competition between component crops for nutrient usage is more pronounced in the intercropping system (38).…”

“…It is one of the most efficient land use systems in tropical places where farmers have limited access to agricultural inputs (10). Intercropping increases crop productivity (11), boosts the land usage ratio (12), considerable reduction in greenhouse gas emissions (13), allows for a wellbalanced diet, reduces labor peaks, reduces crop failure (14), helps to keep soil from eroding, improves yield stability and enhances profits (15) compared to the sole cropping system. It was stated that intercropping is vital for optimal space and physical resource utilization (16).…”

Food production on continuously declining agricultural land to feed the ever-increasing population is a severe issue in Ethiopia. The present study was therefore initiated to evaluate inter and intra-row spacing on yield performance, land-use efficiency and competition in bread wheat-sweet lupine additive series intercropping system. Field experiments were conducted for 2 years in Adet and Debre Tabor experimental sites. The treatments consisted of three inter-rows spacing and 3 intra-rows spacing of sweet lupine. Moreover, the sole crop of wheat and lupine were also included as controls. The experiments were laid out in a factorial randomized complete block design with three replications. The results showed that the combination of 20 cm inter-row spacing with 10 cm intra-row spacing of sweet lupine in bread wheat-sweet lupine intercropping system gave the highest total yield of 4.36 t ha-1 and 4.75 t ha-1 at Adet and Debre Tabor respectively; the land equivalent ratio of 1.43 and 1.57 at Adet and Debre Tabor respectively. System productivity index of 4.96 and 5.88 at Adet and Debre Tabor respectively. Gross monetary value of 2511.26 and 2752.19 USD ha-1 at Adet and Debre Tabor experimental sites respectively. Gross monetary value was generally higher for intercrops than sole cropping systems in both locations; it is linked to intercropping yield and economic benefits compared to sole cropping. Farmers in the study area and areas with similar agroecology are recommended to intercrop sweet lupine with bread wheat at 20 cm inter-row spacing with 10 cm intra-row spacing of sweet lupine.

“…growth whilst suppressing the growth of the understorey legume crop (Yu et al 2015). When cowpea is severely suppressed and cereal growth is increased, LER values become lower due to reduced cowpea yields (Mead and Willey 1980;Bedoussac and Justes 2011;Bitew et al 2019). In such cases legume yield becomes a main determinant of LER; therefore, LER values become lower (Ofori and Stern 1987).…”

Intercropping is a common practice among farmers in sub-Saharan Africa, regarded as a sustainable way of improving land productivity to meet food and nutritional requirements for a growing population, especially in marginal areas. Cowpea (Vigna unguiculata L. Walp) is often intercropped with major cereal crops, maize (Zea mays L.), sorghum (Sorghum bicolor L. Moench) and pearl millet (Pennisetum glaucum L.R.Br). Here we conducted a systematic literature review on cowpea intercropped with maize, sorghum or pearl millet reported in sub-Saharan Africa with the objectives (i) to determine yield and productivity of component crops and (ii) to quantify biological N 2 -fixation in sole or intercrops. We retrieved 60 unique publications combining 1196, 998 and 25 observations of yields, land productivity and N 2 -fixation, respectively, for crops grown as intercrops and monocrops. The major results are as follows: (1) land productivity of cowpea intercropped with maize, sorghum and pearl millet is favourable, with average land equivalent ratios of 1.42 ± 0.47, 1.26 ± 0.35 and 1.30 ± 0.32, respectively; (2) no significant differences between the proportion of nitrogen derived from the atmosphere (%Ndfa) for sole or intercropped cowpea were found, with average values of 56.00 ± 4.89 and 46.62 ± 7.05, respectively; (3) however, the total amount of fixed nitrogen was higher in cowpea monocropping systems due to higher biomass production; nitrogen fixation was 57 kg N ha −1 and 36 kg N ha −1 in monocrops and intercrops respectively. We conclude that cereal-cowpea intercropping is a pathway for intensification for the low nutrient input systems of smallholder farmers in sub-Saharan Africa. Our review also suggests potential for improvement of these systems, based on the choice of the associated varieties, planting patterns and sowing time, cowpea leaf harvesting as a vegetable, and fertilization.

“…This is a precarious threat that continually subjects smallholders to unwarranted poverty traps within their farming activities. In a broad view, it implies that a rational management of the risks would provide a pathway for smallholders to incessantly contribute towards food security, which is consistent with the attainment of the United Nation's Sustainable development goal of ending poverty and hunger (Bitew, Alemayehu, Adego, & Assefa, 2019;United Nations, 2015).…”

The study examined how multiple factors influence participation of farmers in Weather Index Insurance WII in Embu County, Kenya. Data wer e collected from a sample of 401 smallholders following multi stage sampling technique The study employed the Cragg ’s Double Hurdle model in determining factors that influence participation and extent of participation in WII. Results revealed th at short rain season, household size, land size, perception of the household head on WII , owners h ip of a mobile phone a nd location of the farm were important factors in explaining participation in WII. The distance to a registered agro veterinary products outlet, insurance premium , group membership, the weather station in Runyenjes station and distan c e to the local weather station influenced probability to participate negatively. Similarly, ownership of mobile phone had a positive influence on the extent of participation in WII while the size of the household, distance to a registered agro veterinary p roducts outlet and land size were significant with a negative influence. The findings of this study highlight the importance of shaping farmers’ perceptions to wards WII, promotion of policies that allow for access and use of information and communication t echnologies ( such as mobile phones by the farming households as a pathway to providing smart so lutions to smallholder farmers in dealing with weather rela ted risks . Further, the research recommends for development of policies that would ensure modest WII insurance premiums that are aligned to the unique need s of the smallholder farmers.
