  Due to slow growth and weakness of the first development of chickpea (Cicer arietinum L.) plant could not combatted with weeds and easily get caught up by Ascochyta blight (Ascochyta rabiei (Pass) Labr.) disease; esp. under the late sowing and semi-arid conditions, due to effect of biotic and abiotic stress factors, significant yield losses could be arised. To be able to avoid from them is only possible to accelerate the first development of this crop. So, one of the best solutions is to use of “soil conditioner” chemical compounds such as HA at optimum dose. With this aim, it was established in order to find out the optimum dose range of HA. Three doses (D0 = 0 g, D1 = 100 g and D2 = 200 g), four varieties (V1 = Er–99, V2 = Gökçe, V3 = ILC-482 and V4 = Australia) and five yield components (Plant Height (PH), First pod height (FPH), Number of Branches per Plant (NBP), Number of Pods per Plant (NPP) and Number of seeds per pod (NSP) were investigated. Obtained results are: Recommended (Optimum) HA doses and interactions were ranged and found as (V4>V2=V3>V1); (D2>D0=D1); (D1xV4) for the PH and FPH, (D2xV3) for the NBP and (D1xV3) for the NPP, respectively. It was concluded that when the recommended HA dose applied, it was seen that the first development has been clearly accelerated and increased under the semi-arid conditions in terms of investigated traits and cultivars.

  Due to the slowness growth and weakness of the first developments of chickpea (Cicer arietinum L.), it could not combated with weeds and easiliy caught up by Ascochyta blight (Ascochyta rabiei (Pass) Labr.) disease. Additionally, due to biotic and abiotic stress factors, esp. at the late sowing, important seed yield losses could be happened. To be able to avoid from them is only possible to accelerate of its first development as possible as. So, one of the best solutions to is to use chemical compounds such as Humic Acid (HA) known soil regulator under the semi-arid conditions. With this aim this research was performed in a Randomized Complete Block Design (RCBD) with four replications under semi-arid field conditions during (2008/2009) and (2009/2010) in Turkiye. Two cultivars (V1 = Gokce and V2 = Ispanyol) and four seed imbibition methods (A0 = 0, A1 = Tap Water, A2 = ½ Tap Water + ½ Humic acid (HA), A3 = Full HA, as w/w) and seven yield components Plant Height (PH), Number of Branches per Plant (NBP), Number of Pods per Plant (NPP), First Pod Height (NFP), Number of Seeds per Pod (NSP), Seed Weight per Plant (SWP) and 100-Seed weight (HSW) were investigated. The PH and FPH were affected the A0, the NBP, NPP and NSP were affected the A2 and the SWP and HSW were given the varied but not clear responses according to varieties for all the parameters in A1. The A0 and A1 were encouraged the germination and top soil of the plant but, the A2 to A3 were encouraged root system’s development. It was concluded that the A2 is a promising method which makes the maximum and positive effect to the first development of the chickpea agronomy under the semi-arid conditions.
