Effect of amount of sugarcane compost and nitrogen on quantitative and qualitative yield of corn (Zea mays L.)

Considering the production of sugarcane compost in some sugarcane companies and the need for using these products as organic fertilizers to reduce the application of chemical fertilizers, this experiment was conducted to investigate the effect of different amounts of sugarcane compost and nitrogen fertilizer on quantitative and qualitative yield of corn. In this study, split plots were used in a randomized complete block design with three replications. The treatments consisted of different amounts of sugarcane compost at three levels of 0, 15, and 30 ton/ha as main plots and nitrogen fertilizer from urea source at three levels of 80, 160, and 240 kg/ha nitrogen as sub plots. Results showed that the effect of sugarcane compost and nitrogen on number of rows per ear, number of seeds per ear, 1000 grain weight, grain yield, and protein yield were significant but the effect of interaction between treatments on all traits were not significant. The maximum grain yield and protein yield were obtaied under 30 ton/ha sugar cane compost and 240 kg/ha nitrogen and the minimum grain yield and protein yield were in non-consuming sugarcane compost and 80 kg/ha nitrogen. In general, the results of experiment showed that increasing the application of sugarcane compost and nitrogen up to 30 ton/ha and 240 kg/ha, had a significant effect on quantitative and qualitative yield of corn and can be considered by farmers and researchers.
