Abstract
A field experiment was conducted in experimental farm of Sugarcane Research Institute of Khuzestan province at 2019-2020 growing season, in order to examination of fertilizer type and weed management on sugar cane quantitative and qualitative yield. Experimental design was factorial on randomized complete block design (RCBD) with three replications. The treatments include first factor (fertilizer type) with three levels (Control (Without fertilizer), Foliar application of N, P, K and compost of sugar cane bagass and the second factor was weed management with four levels (Control, weed free, spraying with Allion herbicide, Spraying with Sencor herbicide). In this study, quantitative traits such as stem height, number of stems, stem diameter stem dry weight, sugarcane yield, qualitative traits such as purity percentage, soluble sucrose and sucrose yield were measured.The results showed that complete weed control treatment and compost application (sugarcane bagasse) significantly increased sugarcane yield (84.09 tons per hectare) and sucrose yield (10.09%). Therefore, it can be suggesting that using a complete control treatment and use compost in Ahvaz can be effective and economical. dry weight of stems as well as total dry weight of sugarcane increased with decreasing weed interference time. fertilizer type also had a significant effect on the studied traits. Weed free management and application of Allion herbicide reduced dry and wet weight and density of jungle rice weed in sugarcane. Sucrose yield was increased by application of compost and foliar application of elements. Also, the highest percentage of purity and soluble sucrose was obtained by using compost. According to the results, it can be suggesting that the use of organic fertilizers (bagasse compost) in sugarcane cultivation is one of the solutions that can be used to nourish and improve plant growth and in addition to protecting the environment
