“…ICHEC predicted an increase of rainfall of 25% under RCP8.5. Similar small magnitude of variation in RCP4.5 and higher magnitude of variation in RCP8.5 were also obtained for mean annual rainfall which is predicted to increase in the Sudanian Savanna by about 1.7% and 1.9% in 2030s and by 4.4% and 16.1% in 2030s under the respective scenarios RCP4.5 and RCP8.5 (Mohammed et al 2016). With reference to CMIP5 (Coupled Model Intercomparison Project Phase 5), the majority of the climate model outputs we used seem to be contrary to the positive precipitation trend which is predicted by 50% of the models in CMIP5 model ensemble.…”

“…Later on, on-farm studies in major growing areas indicated that mid-August to early September is the ideal period for chickpea planting under rainfed condition (Bejiga and Tullu 1982). More recently, a simulationbased sowing time study conducted in two sites of the northeastern region using CROPGRO model (Hoogenboom et al 2010) indicated that mid-August sowing had significant yield advantage over the traditional late (September) sowing (Mohammed et al 2017). Most of these and earlier studies reported that any delay from this time window can cause up to 50% yield reduction (Fig.…”

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.

“…Chickpea is being grown in more than fifty countries across the globe (Upadhyaya et al, 2011 ; Gaur et al, 2012b ). It is the most important food legume crop, grown in tropical, subtropical, and temperate regions (Mohammed et al, 2017 ). Chickpea is cultivated mostly in the rainfed condition (Kumar and Abbo, 2001 ) and drought is a major constraint for chickpea production (Toker et al, 2007 ).…”

Chickpea (Cicer arietinum L.) is an economically important food legume grown in arid and semi-arid regions of the world. Chickpea is cultivated mainly in the rainfed, residual moisture, and restricted irrigation condition. The crop is always prone to drought stress which is resulting in flower drop, unfilled pods, and is a major yield reducer in many parts of the world. The present study elucidates the association between candidate gene and morpho-physiological traits for the screening of drought tolerance in chickpea. Abiotic stress-responsive gene Dehydrin (DHN) was identified in some of the chickpea genotypes based on the sequence similarity approach to play a major role in drought tolerance. Analysis of variance revealed a significant effect of drought on relative water content, membrane stability index, plant height, and yield traits. The genotypes Pusa1103, Pusa362, and ICC4958 were found most promising genotypes for drought tolerance as they maintained the higher value of osmotic regulations and yield characters. The results were further supported by a sequence similarity approach for the dehydrin gene when analyzed for the presence of single nucleotide polymorphisms (SNPs) and indels. Homozygous indels and single nucleotide polymorphisms were found after the sequencing in some of the selected genotypes.
