Fertilización nitrogenada en poda de producción en el cultivo de mora de castilla (Rubus glaucus Benth)

Abstract

The fruits are of great economic interest for its high production and demand in the market; such as blackberry (Rubus glaucus B). therefore they have generated several investigations of fertilization With the objective of increasing the quality and yield of the fruit, However, the lack of efficiency in the use of N is low, the following research aimed to develop a nitrogen fertilization management plan with fractional doses of ammonium nitrate in the test in Castilla mora (Rubus glaucus B). The experiment was performed with 3 treatments and a control, it was used the randomized complete block design, with three replications. They were evaluated the variables Number of vegetative buds, Number of productive buds, Number of new primary branches, Number of production centers, Number of sprouted buds, Number of sprouted flowers, Number of fruit set, the data were subjected to an analysis of variance and examined by Tukey's significance tests at 5% using the Infostat statistical program. The application of T2 nitrogen fertilization treatments with (300kg/ha ammonium nitrate), reported the highest results in the variables proposed in the trial, obtaining better results in the cultivation of blackberry for farmers to dedicate themselves to production. of this crop, using nitrogen fertilization methods. The control according to the corresponding phase of the crop was the one that produced the least results during the investigative trial, since by not applying any fertilizer it does not react properly, preventing the normal development of the crop, producing losses, low production and profitability, therefore, it is necessary to apply a certain amount of nitrogen to the plant.
