Enmiendas orgánicas en la producción de col (Brassica oleracea var capitata)

The purpose of this trial was to solve the nutritional requirements of cabbage using organic amendments (Gallinaza and Cuyaza) associated with conventional fertilization. For this, it was proposed to evaluate the organic amendments plus conventional fertilization, defining an experiment with 4 treatments (T1: Gallinaza + Conventional Fertilization; T2: Gallinaza; T3: Cuyaza + Conventional Fertilization; T4: Cuyaza). A Random Block Design was used, in which each treatment was evaluated by means of 5 repetitions which was submitted to the analysis of variance and the Tukey Test with a 5% probability of error. The treatments had a dose of T1: Chicken manure (173.38kg / ha) + Conventional fertilization (117kgN / ha; 654kgP / ha); T2: Gallinaza (173.38kg / ha); T3: Cuyaza (173.39kg / ha) + Conventional fertilization (117kgN / ha; 654kgP / ha) and T4: Cuyaza (173.39kg / ha). Among the variables evaluated were plant height, cabbage diameter, cabbage weight and yield. Significant differences were only observed in the variable diameter of the cabbage, in the treatments where there was interaction between organic amendments and conventional fertilization, T1: 10.92cm and T3: 10.98cm, which presented the best statistical average. In the results in the B / C ratio, it was observed that no treatment is profitable because the net benefit was low.
