“…The length of reproductive growth (from anthesis to maturity) was included in the logic, based on previous findings (Gan et al 2002) that a prolonged reproductive phase in chickpea increases heat unit accumulation for pod setting and seed formation. Early pod set through shortening the reproductive period or early flowering in chickpea has been recognized as a prime strategy for avoiding drought stress in semiarid environments prone to end-of-season moisture stress (Kumar and Abbo 2001).…”

Chickpea (Cicer arietinum L.) seed yield can be increased by identifying and managing the key yield components. A field study was conducted in southwestern Saskatchewan in 1999 and 2000 to determine the direct and indirect effects of various yield components on chickpea seed yield . Both desi- and kabuli-chickpea were planted at the target plant populations of 20, 30, 40, and 50 plants m-2 on conventional summerfallow (CS) and no-till wheat stubble (NT). Path coefficient analyses revealed that seed yield for both chickpea classes largely depended upon pods m-2 and seed weight, with the kabuli crop having higher coefficient values than the desi. These relationships were stronger when the pulses were grown on CS than on NT. Seeds pod-1 had a negative effect on seed yield for the kabuli crop, but this negative effect was counterbalanced by a strong, positive effect of seed weight on seed yield. The total pod production of the desi crop depended on plants m-2 more than on pods plant-1, whereas the pod production of the kabuli crop relied equally on plants m-2 and pods plant-1. For both chickpea classes, mean seed weight decreased with prolonged vegetative growth period regardless of tillage environment. Seed weight was positively related to the length of reproductive growth and seeds pod-1 only when the pulses were grown on CS. Seed yield potential of desi chickpea would be increased by increasing plant population to produce more pods per unit area, whereas the seed yield potential of kabuli chickpea would be increased by shortening the period of vegetative growth, promoting the number of pods per plant, and increasing mean seed weight.

. 2003. Optimum plant population density for chickpea and dry pea in a semiarid environment. Can. J. Plant Sci. 83: 1-9. Chickpea (Cicer arietinum L.), an annual grain legume, is being broadly included in cereal-based cropping systems throughout the semiarid Canadian prairies, but information on optimum plant population density (PPD) has not been developed for this region. This study, which was conducted from 1998 to 2000 in southwestern Saskatchewan, determined the effect of PPD on field emergence, seed yield and quality, and harvestability of kabuli and desi chickpea compared with dry pea (Pisum sativum L.). Seed yields of all legumes increased with increasing PPD when the crops were grown on conventional summerfallow. The PPD that produced the highest seed yields ranged from 40 to 45 plants m -2 for kabuli chickpea, from 45 to 50 plants m -2 for desi chickpea, and from 75 to 80 plants m -2 for dry pea. When the legumes were grown on wheat stubble, the PPD that gained optimum seed yield ranged from 35 to 40 plants m -2 for kabuli chickpea, from 40 to 45 plants m -2 for desi chickpea, and from 65 to 70 plants m -2 for dry pea. The proportion of large-sized (>9-mm diameter) seed in the harvested seed was >70% when the kabuli chickpea was grown on summerfallow regardless of PPD, whereas the large-seed proportion decreased with increasing PPD when the crop was grown on wheat stubble. Increases in PPD advanced plant maturity by 1.5 to 3.0 d and increased the height of the lowest pods from the soil surface by 1.4 to 2.0 cm (or 5 to 10%), with desi chickpea receiving the greatest benefits from increased PPD. The percentage of plants established from viable seeds per unit area decreased substantially as PPD increased, with kabuli chickpea emergence decreasing from 90% at PPD = 20 plants m -2 to 72% at PPD = 50 plants m -2 , from 81 to 69% for desi type, and from 83 to 59% for dry pea. The reason for the low field emergence with increased PPD is unknown, but methods which lead to improved field emergence represent a great opportunity to increase seed yield and reduce production costs for both chickpea and dry pea in this semiarid region. Quand on cultive le pois chiche kabuli sur une jachère d'été, la proportion de grosses semences (> 9 mm de diamètre) dépasse 70 %, peu importe la DPO, mais un relèvement de cette dernière diminue la proportion de grosses semences quand la culture pousse sur du chaume de blé. Une hausse de la DPO permet aux plants de parvenir à maturité de 1,5 à 3,0 jours plus tôt et les gousses les plus basses dépassent le sol de 1,4 à 2,0 cm de plus (soit 5 à 10 %). C'est le pois chiche desi qui bénéficie le plus d'un relèvement de la DPO. La proportion de plants issus de semences viables par unité de surface diminue sensiblement avec l'augmentation de la DPO. Ainsi, le pourcentage de levée du pois chiche kabuli tombe de 90 à 72 % quand la DPO passe de 20 à 50 plants au m 2 , alors qu'il tombe de 81 à 69 % pour le pois chiche desi et de 83 à 59 % pour le pois de grande culture.

“…About 90% of world's chickpea is grown under rainfed conditions (Kumar and Abbo 2001), where the crop grows and matures on a progressively depleting soil moisture profile and generally experiences terminal drought stress (DS). Drought causes substantial annual yield losses up to 50% in chickpea, which equals to a loss of US $ 900 million, and the productivity remained constant for the past six decades (Ryan 1997;Ahmad et al 2005;Bantilan et al 2014).…”

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.
