Abstract

The experiment was conducted during 2018 and 2019 in Oshnavieh city as factorial based on a randomized complete blocks design with three replications. The main factor was included of the application of biological and chemical fertilizers: control (no fertilizer), Phosphate2 as a biological fertilizer, ammonium phosphate as a chemical fertilizer, 50% chemical fertilizer+50% biological fertilizer and 100% chemical fertilizer + 100% biological fertilizer and secondary factor was included as foliar spraying of seaweed extract in three levels of control, application before flowering and application after flowering. The results showed that application of seaweed extract before flowering or after flowering caused a significant increase in the number of pods per plant and the one handred grain weights. The highest grain yield in the first year (133.7 g.m-2) was obtained under the combined treatment of biological and chemical fertilizers (50:50) with the use of seaweed extract before flowering stage and in the second year (149.0 g.m-2) under combined treatment of biological and chemical fertilizers (100:100) with the application of seaweed extract after flowering stage, the amount of soluble sugar was obtained with the combined use of biofertilizer and chemical fertilizers under foliar spraying of seaweed extract before or after flowering stages. The percentage of chickpea grain protein showed a significant increase in the first year with separate or combined application of biological and chemical fertilizers compared to the control, and in the second year it showed the highest increase with the application of chemical or combined fertilizers.
