Abstract

The research was conducted at AL-Husseinia village, north Deir Ezzor governorate, during 2018/2019 growing season, to study the effect of sowing date and addition of humic acids on growth and yield of chickpea under conditions of Deir Ezzor governorate. The studied factors in this experiment were: sowing dates (25/12) and (25/1), and the second factor was the addition method of humic acids as follow: – control without humic acids, – foliar spraying with humic acids, – and adding humic acids with irrigation. The organic fertilizer Humax ( commercial product) was used as source of humic acids. Experimental design was RCBD with arranging treatments in split-plot design with three replications. Results showed that sowing date in 25/12 significantly surpassed 25/1 sowing date in most of studied traits at harvest. The productivity of 25/12 sowing date reached to 2822.3 kg/ha, while it was 2114.7 kg/ha in 25/1 sowing date. Generally the addition of humic acids resulted an increasing in growth and productivity of chickpea. Foliar application of humic acids, gave the highest values of number of branches/plants, 100 seed weight, number of fully pods/plant and seed yield per unit area as compared with adding with irrigation and control treatments. However, the differences between the two addition methods (foliar and adding with irrigation), weren’t significant, for plant dry weight and plant height at harvest. The highest productivity of seed (3050 kg/ha) was obtained from sowing chickpea on 25/12 with foliar application of organic fertilizer.

Keywords: Chickpea, Sowing date, Humic acids, Organic fertilizer, Growth traits, Yield.
