“…Finger millet (Eleusine coracana L.) is a widely grown cereal crop in some arid and semiarid areas in Africa, such as Ethiopia. Field assays in which ringer millet was intercropped with three vetch species, including V. sativa, concluded a general improving of the total dry matter yield and the quality of the intercrops [ 71 , 72 , 73 ]. Although the most well-characterized intercropped systems are those of legume cereal, other systems have been documented as intercropping with rapeseed ( Brassica napus L.), which require higher levels of N fertilizers [ 73 ].…”

Common vetch (Vicia sativa L.) is a grain legume used in animal feeding, rich in protein content, fatty acid, and mineral composition that makes for a very adequate component to enrich feedstuff. In addition, relevant pharmacological properties have been reported in humans. The common vetch, similar to other legumes, can fix atmospheric nitrogen, a crucial feature for sustainable agricultural systems. These properties enhance the use of vetch as a cover crop and its sowing in intercropping systems. Moreover, several studies have recently pointed out the potential of vetch in the phytoremediation of contaminated soils. These characteristics make vetch a relevant crop, which different potential improvements target. Varieties with different yields, flowering times, shattering resistance, nutritional composition, rhizobacteria associations, drought tolerance, nitrogen fixation capacity, and other agronomic-relevant traits have been identified when different vetch accessions are compared. Recently, the analysis of genomic and transcriptomic data has allowed the development of different molecular markers to be used for assisted breeding purposes, promoting crop improvement. Here, we review the potential of using the variability of V. sativa genetic resources and new biotechnological and molecular tools for selecting varieties with improved traits to be used in sustainable agriculture systems.

Compatible production of forage grasses and legumes through intercropping is one of the best options to achieve higher biomass yield and forage quality for animal production in areas where land and other resources are scarce. This study was conducted in 2017 and 2018 with the aim of evaluating the best-match level of seeding rate of silverleaf desmodium (SLD) intercropped with desho grass (Pennisetum pedicellatum) in a randomized complete block design with three replications. The treatment consists of three levels of seeding rate of SLD (2, 4, and 6 kg ha−1) and one pure plot of each species. The result of this study showed that the intercropping of 6 kg ha−1 SLD with 100% of desho’s recommended plant population (50,000 plants ha−1) produced the highest forage dry matter yield and maximum plant height. The total dry matter yield (TDMY) of the intercrops was also significantly varied for the tested treatments. Accordingly, 6 kg ha−1 of SLD intercropped with 100% recommended seed rate of desho ha−1 gave the highest forage TDMY, which surpasses both the grass and legume yields in monoculture. The total land equivalent ratio (LER), which shows system productivity, was also different among the treatments. About 6 kg ha−1 of SLD intercropped with 100% recommended seed rate of desho also produced the highest LER (1.51). Thus, in Bako and similar agro-climatic conditions, where arable land is heavily covered with food crops, desho grass intercropping with SLD can be used as one of the best strategic options for producing feeds of energy and protein sources simultaneously on the same area of land.

Post planting seedling management activities are important factors that determinegrowth and survivalof tree species. A study was conducted to evaluate the effect of management regimes on growth and survival ofCordia africana, Croton macrostachyus, Vachelliaabyssinica, and Grevillea robustatree species. The management regimes (treatments)were with and without application of fertilizer, irrigation and weeding. Management regimeswere arranged in split-split-split plot design replicated three times with tree species as main plot factor and other treatments randomized totheir assigned sub plots. Plant height, root collar diameter and survivaldata were collectedfor statistical analysis. The nonparametrictestKaplan-Meierwas used to estimatesurvival probabilities. Besides, multivariate analysis and Tukey HSD for post hoc testswereemployed for assessing management effects on growth parameters of the tree species. Accordingly, time and management regimes significantly affected growth and survival of tree species. Seedlings with one and four months after planting had better survival and growth rates than twenty months after planting. Apart from main effects fertilizer and weeding, management regimes revealed no interaction effects.Vachelliaabyssinica and Cordia africanahadhigher survival rates, whileVachelliaabyssinica revealed least in growth rate. Height and diameter of Cordia africana and Croton macrostachyushad significant and strong correlations with fertilizerand so does weeding withGrevillea robusta.Generally, management regimes improved growth and survival of the tree species. However, effect of irrigation and fertilizer rates on growth and survival of agroforestry tree speciesrequires further systematic study for packaging management recommendation.
