Evaluación de la eficacia del fotosint en 3 dosis de aplicación sobre el rendimiento en el cultivo de Brócoli (Brassica oleracea l. Var Italica CV.Avenger) en la comunidad de Gatazo Zambrano.

Abstract

The purpose of the present research is to evaluate the efficacy of fotosint in 3 doses on the performance of broccoli crop (Brassica oleracea L. var Italica cv. Avenger) in the “comunidad de Gatazo Zambrano” by using the experimental design, of Random Complete Blocks (DBCA), with four treatments, including a control and three replicates. The treatments resulted applying three doses: low (1cm3/l), medium (2cm3/l), high (3cm3/l) of Fotosint product and the control Bioplus (2cm3/l), with a frequency of every two weeks. On the other hand, under the environmental conditions of the research area; there were differences between the doses used in the height, days to the appearance of pellet, days before harvest, pellet weight, equatorial diameter and yield. The best performance presented the treatment T3 (Fotosint in a dose of 3cm3/l) with 20661, 11 kg /ha, exceeding from 9.25% to 25.3% to the treatment, in which applied 1cm3/l (T1). The best benefit-cost relation presented the treatment after applying the organic foliar Fotosint in a dose of 3cm3/l with values of 150,90 % and 2,51. It is recommended to apply 10, 5 l/ha of Fotosint including 399g N-367,50g P2O5 -241, 50 g K2O -8,27g CaO to obtain a better performance and quality of the final product, and to carry out studies on fractioning times, being a determining factor in the performance.
