Abstract
The present study entitled “Agro-physiological evaluation of chickpea (Cicer arietinum L.) genotypes
under moisture soil stress. ” was conducted at Drought plot area, physiology lab, Agronomy Research
Area, CCSHAU,HISAR during rabi 2017-18 with the objective to study the effect of soil moisture
conditions on growth, yield attributes and yield, nutrient uptake, physiological parameters and
economics of various chickpea genotypes. In the two main plots three replications of six genotypes
were sown. In one plot two irrigations was applied one at pre-flowering stage and other at pod
development stage. The environments and chickpea genotypes show significantdifference in respect of
various phenological events (except emergence) viz. 50 per cent flowering, 50% pod development and
physiological maturity. More number of days was taken in irrigated environment to attain various
phenological stages as compared to rainfed environment. The growth parameters viz. plant height, dry
matter accumulation and leafarea per plant, yield attributing characters [no. of branches, no. of pods per
plant, number of seeds per pod, 100 seed weight, seed yield (kg ha-1), straw yield (kg ha-1) and
biological yield differed significantly among differenttreatments. H 13-36 genotype was significantly
superior in terms of growth and yield and its attributes in comparison to other genotypes. The number
of nodules and dry weight of nodules was significantly higher in case of irrigated environment and
physiological parameters viz. canopy temperature, chlorophyll content, leaf water potential and relative
water content different significantly in both the environments. In irrigated environment higher gross
return (₹97958), net returns (₹45970) and B:C (1.88) as compared to rainfed environment. Soil
moisture content show continuous decrease in rainfed environment. Consumptive use of water and
water use efficiency were higher in case of irrigated environment.
