Abstract:

Due to the high importance of using organic fertilizers in sustainable agriculture, the present research was carried out as a factorial experiment based on randomized complete block design in Agricultural and Natural Resources Research Station in Khoy during growth season of 2015-2016. The first factor included foliar application time at three stages of six leafy, stemming and pre-flowering of sorghum, and the second factor included the foliar application of seaweed (seaweed extract 40%, N 8%, K 22%, P 18%, amino acid, Alginic, cytokinin 5cc/lit), HB-101(growth stimulus 1cc/lit), macro (NPK (20, 20, 20) 2cc/lit), water, and control. Through applying foliar at all three stages, the amounts of crude fiber, soluble fiber in acidic, and neutral detergents decreased, while digestibility increased. Compared to foliar application of water and control in all three stages, the foliar application with seaweed and Hb-101 increased digestibility (14%) and soluble sugar (105%) during the stemming. Seaweed foliar application (16/48) had the highest amount of crude protein during stemming. Foliar application of liquid fertilizers had the highest amount of leaf level index during six leafy and stemming stages in comparison with foliar application with water and control at all three stages, there was a 34% rise. During stemming, foliar application with seaweed and Hb-101 resulted in 54% and 46% increase in function, respectively, which was the highest statistical group. Apart from improving the quality and profitability of the farming, the use of organic fertilizers is an important step towards the realization sustainable agriculture and are recommended.
