“…Root growth simulation studies have not only confirmed the importance of deeper root systems and root proliferation on grain yield across several years and environments in USA (Sinclair 1994) but also on chickpea under Iranian conditions (Soltani et al 1999). The chickpea simulation studies have also showed that early maturity, increasing drought avoidance through deep and profuse root system and higher transpiration efficiency were the traits most likely to result in higher yield under terminal DS (Soltani et al 2000).…”

Abstract. Chickpeas are often grown under receding soil moisture and suffer~50% yield losses due to drought stress. The timing of soil water use is considered critical for the efficient use of water under drought and to reduce yield losses. Therefore the root growth and the soil water uptake of 12 chickpea genotypes known for contrasts in drought and rooting response were monitored throughout the growth period both under drought and optimal irrigation. Root distribution reduced in the surface and increased in the deep soil layers below 30 cm in response to drought. Soil water uptake was the maximum at 45-60 cm soil depth under drought whereas it was the maximum at shallower (15-30 and 30-45 cm) soil depths when irrigated. The total water uptake under drought was 1-fold less than optimal irrigation. The amount of water left unused remained the same across watering regimes. All the drought sensitive chickpea genotypes were inferior in root distribution and soil water uptake but the timing of water uptake varied among drought tolerant genotypes. Superiority in water uptake in most stages and the total water use determined the best adaptation. The water use at 15-30 cm soil depth ensured greater uptake from lower depths and the soil water use from 90-120 cm soil was critical for best drought adaptation. Root length density and the soil water uptake across soil depths were closely associated except at the surface or the ultimate soil depths of root presence.

“…Water use/conservation and water capture are composed of several 'pieces', and the effects of these pieces are more easily modelled than assessed. For example, using a robust crop model for chickpea, Soltani et al (1999) showed that an early decline in leaf expansion and transpiration upon soil drying led to yield improvement under water stress conditions, although the yield improvements obtained were <5%. Although these two traits were discussed in earlier sections as potential key water saving traits, this example illustrates that under the geographical conditions in which the model was used, these traits had only limited interest, and making an investment in breeding them was not a priority.…”

Abstract. Water deficit is the main yield-limiting factor across the Asian and African semiarid tropics and a basic consideration when developing crop cultivars for water-limited conditions is to ensure that crop water demand matches season water supply. Conventional breeding has contributed to the development of varieties that are better adapted to water stress, such as early maturing cultivars that match water supply and demand and then escape terminal water stress. However, an optimisation of this match is possible. Also, further progress in breeding varieties that cope with water stress is hampered by the typically large genotype Â environment interactions in most field studies. Therefore, a more comprehensive approach is required to revitalise the development of materials that are adapted to water stress. In the past two decades, transgenic and candidate gene approaches have been proposed for improving crop productivity under water stress, but have had limited real success. The major drawback of these approaches has been their failure to consider realistic water limitations and their link to yield when designing biotechnological experiments. Although the genes are many, the plant traits contributing to crop adaptation to water limitation are few and revolve around the critical need to match water supply and demand. We focus here on the genetic aspects of this, although we acknowledge that crop management options also have a role to play. These traits are related in part to increased, better or more conservative uses of soil water. However, the traits themselves are highly dynamic during crop development: they interact with each other and with the environment. Hence, success in breeding cultivars that are more resilient under water stress requires an understanding of plant traits affecting yield under water deficit as well as an understanding of their mutual and environmental interactions. Given that the phenotypic evaluation of germplasm/breeding material is limited by the number of locations and years of testing, crop simulation modelling then becomes a powerful tool for navigating the complexity of biological systems, for predicting the effects on yield and for determining the probability of success of specific traits or trait combinations across water stress scenarios.

“…Chickpea yield is the ultimate consequence of the amount of dry matter produced during the growing season being partitioned into seed (Soltani et al 1999). Lopez-Bellido et al (2004) demonstrated that both BM and HI were closely related to chickpea seed yield in the Mediterranean region.…”

, T. 2006. Biomass and yield performance of kabuli chickpea cultivars with the fern or unifoliate leaf trait in the Northern Great Plains. Can. J. Plant Sci. 86: 1089-1097. Chickpea (Cicer arietinum L.) has two kinds of leaf, the fern and unifoliate. The best leaf type to use for biomass production and yield in the short growing season of the Northern Great Plains, which has a semiarid environment with end of season rainfall, is not yet known. The objectives of this research were to determine the relationships between leaf type and crop growth rate, maximum above-ground biomass, harvest index and yield under moderate and high plant population densities. The study was conducted in the field at Saskatoon and Swift Current, Saskatchewan, in 2003 and. The experimental treatments consisted of a factorial combination of six commercial kabuli chickpea cultivars representing the two leaf types and two plant population densities: 45 and 85 plants m -2 . There were no cultivar and plant population interactions for crop growth rate, maximum above-ground biomass, harvest index and seed yield. Dry matter production was higher in the 2004 season, which had above-average rainfall and a longer duration of reproductive growth. Although high plant population exhibited higher maximum above-ground biomass in 3 location-years, plant population did not affect the crop growth rate. The 45 plants m -2 treatment had a higher harvest index than the 85 plants m -2 treatment in 2 location-years, but both population treatments were similar in the other two environments. Yield of chickpea was increased by higher plant population in 1 location-year, but was not affected by plant population in the other location-years. The fern leaf cultivars had a higher crop growth rate over the unifoliate leaf cultivars in 2 location-years and no significant difference in the other environment. Fern-leaf cultivars partitioned more dry matter to seed growth compared with unifoliate cultivars while sustaining similar biomass production as unifoliate cultivars. The use of fern-leaf cultivars in the Northern Great Plains appears to be an opportunity for increasing chickpea yield by its superior harvest index compared with unifoliate leaf cultivars. ) a deux sortes de feuillage : les feuilles de fougère et les feuilles simples. On ignore lequel se prête le mieux à la production de biomasse et au rendement dans le nord des grandes plaines, région qui se caractérise par une brève période végétative et un milieu mi-aride avec des précipitations en fin de saison. La présente étude devait préciser les relations entre la sorte de feuille et le taux de croissance de la culture, la biomasse maximale des organes aériens, l'indice messianique et le rendement à un peuplement de densité moyenne ou élevée. L'expérience s'est déroulée sur le terrain, à Saskatoon et à Swift Current, en Saskatchewan, et a duré deux ans (2003 et 2004).
