Abstract

Background and Objective: In modern agriculture, the use of plant growth stimulants is one of the ways to increase the yield of strategic plants,
Materials and methods: In order to evaluate and investigate the effect of plant growth stimulants on some quantitative and qualitative characteristics of wheat, this research was conducted in the form of a randomized complete block design with 15 treatments and 4 replications in the crop year of 2019 in the research farm of the Faculty of Agriculture of Mohaghegh Ardabili University, Ardabili. The test treatments include different seed coating treatments at 6 levels (3, 6 and 9 gr kg-1 of humic acid and seaweed extract) and seed priming at 3 levels (priming with 6 mg l-1 of humic acid and extract seaweed and hydropriming (control hydroprime) and spraying with a concentration of 200 and 300 mlgr l-1 of humic acid and seaweed extract, pure water spraying and treatment without pretreatment and without spraying (control).
Results: The results showed that different methods of using plant growth stimulants with seaweed extract and humic acid had a significant effect in increasing the number of claws per plant, the number of spikes per square meter, the length of the spike, the number of seeds per spike and the weight of 1000 seeds compared to the control. Under spraying with a concentration of 300 mlgr l-1 of humic acid, the highest grain yield and biological yield of wheat were obtained with 7694.10 and 19074.90 kg ha-1, respectively.
