Evaluation of the Effect of Various Amounts of Humic Acid on Yield, Yield Components and Protein of Chickpea Cultivars (Cicer Arietinum L.)

Objective: In addition to the role of organic matter in plant nutrition, this material improves soil quality, physical structure, ventilation and water supply, and ease of penetration and expansion is rooted deep in the soil surface. Effects of organic matter due to climatic factors, soil characteristics may vary from region to region, resulting in organic materials management must be given to all factors affecting. Methods: Effect of various amounts of Humic acid on yield, Yield Components and Protein of Chickpea Cultivar s an experimental was conducted on farms of Raan Agricultural Company in spring 2013 at the city of Firouzkouh in a factorial based on randomized complete block design format with three replication In this test, Humic acid was studied in four levels of nil (control), 1.5, 3 and 4.5 kg in each ha on three species of chickpea named ILC482 , Hashem and Arman . Humic acid solution spraying was conducted at three stages of 2-4 leaves, 6-8 leaves and early flowering stage. Results: The Delete results showed that use of Humic acid has had significant effect on most of studied traits and at the level of 1% and 5% probability. Use of 3 kg of Humic acid in each hectare showed more effect in most studied traits. The maximum percentage of protein was obtained in use of 3 kg of Humic acid in each hectare as much as 20.48 percent while the minimum amount (11.41 percent) related to the control group. The results showed that significant difference was observed between species of chickpea in terms of studied traits. The chickpea species ILC482 stood at superior rank than the others species in terms of yield, Yield production with its yield rate of 2,386 kg in each hectare
