Organic Fertilizer Libro and Growth Retardant Role in Phenotypic and Biochemical Traits of Bermuda Grass (Cynodon Dactylon L.)

Abstract

The prevailing study aimed to determine the effects of organic fertilizer Libro with four concentrations (0, 1, 2, and 3 ml L-1) and the growth retardant Cultar with three concentrations (0, 0.03, and 0.05 mg L-1) on Bermuda grass (Cynodon dactylon L.) in a randomized complete block design (RCBD), carried out in 2022 at the University of Anbar, Iraq. The results revealed that the treatment of plants with organic fertilizer Libro at a concentration of 3 ml L-1 led to a significant increase in most of the vegetative growth characteristics represented by the plant density rate, nitrogen, phosphorus, color degree, and the degree of trampling tolerance 2.500, respectively. The treatment with a growth retardant represented by Cultar reduced cutting times to 2.000.
