“…Similarly, early sown chickpea is commonly subjected to the lethal effect of waterlogging, which also exposes the crop to high risk of wilt/root rot disease complex (Agegnehu and Sinebo 2012;Yimer et al 2018). Currently, the damage caused by these two fungal pathogens is increasingly high, which in extreme cases can cause up to 100% crop losses (Yimer et al 2018;Tebkew and Ojiewo 2016).…”

Chickpea (Cicer arietinum L.) production in Ethiopia is exclusively rainfed. The average national yield remains low comparing to the potentially attainable yield because of the common notion among producers that the crop does not need any nutrient inputs. The newly developed high-yielding cultivars have brought significant yield gains. However, their genetic potentials are still hampered by the traditional crop management practices used and the problematic Vertisol growing conditions. Yields of chickpea grown on Vertisols are limited by poor drainage when sown early and by drought when sown late. This calls for optimization of the balance with minimum tradeoffs in key economic traits. Here, we review research progress on chickpea over the past five decades in Ethiopia, with particular emphasis on crop management practices. The paper gives a comprehensive overview of research findings and information generated on the Vertisol cropping systems, where chickpea is the principal rotational crop under cereal-legume cultivation entailing substantial role in cropping system intensification. It has been noted that the productivity of Vertisol-grown chickpea is largely constrained more by lack of the use of best bet crop management practices than the genetics of a given cultivar. For instance, raised-bed method as compared to the conventional flatbed increased grain and biomass yields by about 74% and 58%, respectively. The current average farm yield of chickpea in Ethiopia is about 55% of the yield potential of the crop, suggesting that farmers can still have rooms to substantially increase yield using improved practices. Based on the cumulative evidences, it can be concluded that the yield potentials of genetically elite cultivars may not be realized without synergistic combination of improved management practices and adequate nutrient use. We, therefore, recommend the integrated use of improved crop management strategies, while the soil physical properties still deserve utmost research attention.

Legume crops are very important group of plants that belong to Fabaceae or leguminaceae family and are rich in different essential amino acids. These legumes prove to be the cheapest and most easily accessible source of required proteins. Humans need proper amount of proteins and essential amino acids that are crucial for the proper functioning of the body. In developed countries a large number of diverse diets including meat, fish, protein, drinks and food supplements are readily available but the developing countries having very small income per capita cannot afford all of these commodities. They fulfill their nutritional value by using legume crops. But in developing countries pulses face a number of biotic challenges. They have low production due to less improved varieties. Major damage to the pulse crops is due to the range of bacterial, fungal and viral diseases that drastically reduce the crop production per unit area. Major diseases of pulse crops include chickpea (Blight, Fusarium wilt, root rot), Green and Black gram (Leaf crinckle virus, Mung bean yellow mosaic virus, Mungbean phyllody disease, Cercospora leaf spot, Powdery Mildew), lentil (Ascochyta Blight, Stemphylium Blight, Anthracnose, Botrytis grey mold, Lentil Rust) and soya bean (Charcoal rot, White mold, Louisiana, Root rot, Septoria glycines, Sclerotium rolfsii, Black root rot). These diseases can be controlled by many physical as well as biological methods that have low cost of production and safe to environment. The detailed elaboration of major pulse diseases and their effective control methods have been summarized in this review paper.

“…Chickpea (Cicer arietinum L.) is the world's second most widely grown pulse legume next to common bean (Phaseolus vulgaris), with particular importance in the semi-arid tropics of sub-Saharan Africa. Ethiopia is sub-Saharan Africa's largest producer, consumer and exporter of chickpea [1], and the sixth largest producer globally [2].…”

Identification of Aluminum Tolerance in Ethiopian Chickpea (Cicer arietinum L.) Germplasm

et al. 2022

Aluminum (Al) toxicity is a major abiotic stress that negatively impacts plant growth and crop productivity. Al ions are released into soil solutions as a function of soil pH, which is in turn determined by a combination of factors, including local geology, historic vegetation and land-use patterns. Selection and use of Al-tolerant crops is a preferred method to address the problem of Al toxicity. The present study evaluated a combination of modern cultivars, advanced breeding lines and a local landrace for Al tolerance using a seedling-based hydroponic assay. Two sequential experiments were conducted to score root and shoot traits in the presence of aluminum. Initially, six Al concentrations (0, 50, 100, 120, 150 and 200 µM) were tested on six chickpea genotypes to identify the single Al concentration that best discriminates among genotypes. Subsequently, 31 chickpea genotypes were evaluated at 0 and 120 µM Al. Progressive declines in trait values were observed in all genotypes with increasing Al, although the degree of sensitivity varied significantly among genotypes. Genotypes were evaluated both for total root length under 120 µM Al and for relative root growth compared to a 0 µM Al control treatment. Considering both parameters, we identified four tolerant chickpea genotypes (DZ-2012-CK-0237, Wollega LV, DZ-2012-CK-0233 and Natoli) and two sensitive genotypes (Akaki and Fetenech). Wollega LV is a local landrace obtained from acidic soil regions of Western Ethiopia, presenting the possibility that historical selection during cultivation on acidic soils might underlie its unusual tolerance. The aluminum tolerance traits identified here are candidates for introgression breeding of new Ethiopian chickpea varieties with potential to increase yield and expand the area of cultivation.
