effects of hydro and hormonal priming on yield and yield components of chickpea (cicer arietinum l.) in irrigated and rain-fed conditions

چکیده
in arid and semi arid, seedling emergence and establishment are key stages for final plant density in chickpea production. drought stress, especially at the end of the growing season, is one of the factors which decrease a main part of chickpea grain yield in these areas. therefore the aims of this study were assess to the effects of hydro priming and hormonal priming by gibberellin and abscisic acid on some growth indicators and yield of chickpea under rain-fed and irrigated conditions. seeds primed with 0 (hydro priming), 50, 100 and 150 ppm of each phytohormones. non-primed seeds also were sowed. examined chickpea cultivar was flip 93-93 (known as azad cultivar). rain-fed conditions shortened the plant life cycle and decreased time to flowering and podding. quantity of yield and yield components were less in the rain-fed conditions than irrigated conditions. irrigation increased grain and biologic yields so grain yield was 439.88 and 689.48 kg/ha for rain-fed and irrigated conditions respectively. hydro-priming could increased the number of secondary lateral branches, lai, grain yield, and harvest index in comparison to the other priming treatments and control (non-primed). gibberellin priming delayed days to flowering and podding about eight days. the highest correlation of grain yield obtained with biological yield (r=0.92), hi (r=0.84), 100-seed weight (r=0.39) and number of pods per plant (r=0.36).
