NITROGÊNIO E CAMA DE FRANGO NA SOQUEIRA DA CANA-DE-AÇÚCAR NO CERRADO

Abstract

Sugarcane culture stands out by its high economic value. This study aimed to evaluate the effect of N-fertilizer and chicken litter rates on sugarcane. The research project was installed at Denusa, in the Cerrado biome in a C production environment. The experimental design was a randomized complete block design (DBC) in a 5 x 5 factorial scheme with 4 replications, 5 nitrogen doses and 5 chicken litternitrogen doses. Chicken bed. Nitrogen rates were: 0, 40, 80, 120 and 160 kg ha-1 using ammonium nitrate as source. The chicken litter doses were: 0, 1, 2, 4 and 8 Mg ha-1. The variables analyzed were: Stem number per meter, Average Stem Diameter, Stem Height in meters, TCH (Tons of Stem per Hectare), TAH (Tons of Sugar per Hectare), ATR, ° Brix, POL and FIBER. Statistical analysis was performed using the regression analysis of variance. Positive impact of treatments was observed in relation to the variables of vegetative development and productivity. For the variables ATR, ° Brix, POL and Fiber (Raw Material Quality Variables) did not fit any of the evaluated statistical models.
