title: Agronomic importance of first development of chickpea (Cicer arietinum L.) under semi-arid conditions: II. Seed imbibition.
abstract: Due to the slowness growth and weakness of the first developments of chickpea (Cicer arietinum L.), it could not combated with weeds and easily 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 = 1/2 Tap Water + 1/2 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.
