Organic Fertilization: Answer in the Sugarcane Development (Saccharum officinarum L.)

The influence of different doses of organic and chemical fertilizers can provide better efficiency in nutrient availability to plants and reduce the application in large quantities. The objective of this study was to analyze the influence of different levels of organic manure and chemical fertilization on the development of plant cane plants. The experiment was conducted in a randomized block design with four replications, each block had 7 treatments (T1 Fertilizing organic 15 t ha-1 of cattle manure; T2 Organic Fertilization 30 t ha-1 of cattle manure; T3- organic manure 45 t ha-1 of cattle manure, fertilizer T4 Chemistry 50% according to the soil soil analysis, fertilizer T5- Chemistry 100% according to the soil analysis, fertilizer T6- Chemistry 150% according to soil analysis and T7- unfertilized control and evaluated on different days after planting. The results showed that the treatments corresponding to organic fertilization (T1, T2 and T3), allowed greater plant growth parameters for height, stem diameter, number of tillers and sugarcane leaves. The organic fertilization in different proportions, following the recommendations according to soil analysis, allows further development of sugarcane plants in sandy soil texture of the Piauí compared to chemical fertilizer.
