Estudio de dos niveles de N, tres de CaO y aplicaciones adicionales de S, Ca+ Zn+B+ Mn, en el rendimiento y calidad de fruto en el cultivo de plátano Musa paradisiaca L.

Abstract:

Investigation came true in a plantation established of hybrid Dominican banana of three elderly years, once The Forest Flower was located in the enclosure marked off by definite limits, parish church Roberto Astudillo, canton Milagro, province of the Guayas. Objectives were: a) Evaluating the agronomic behavior of the cultivation of banana, in response to the different doses of fertilization; b) determining the optimum dose of N, CaO and applications of S and microcomputer elements in banana; and, c) making an economic analysis of the proposed treatments. The studied factors were two nitrogenous levels 150 and 300 kg the N is; three levels of calcium 40, 80 and 120 kg Ca Or /ha; with two additional treatments and an absolute witness. The design of blocks was used completely at random (2 x 3 + 3), in total he analyzed eleven agronomic variables himself, and your averages were analyzed by means of the proof and Tukey to 5 % of probability. Himself I conclude a) All the averages of the measured variables presented the bigger average with the dose of 300 kg N/ha as compared with the 150 kg N/ha; b) racimos/ha's bigger heavy performance caught up with the treatment with 80 and 120 kg of CaO/ha; c) The interaction of N x CaO that he presented racimos/ha's bigger heavy average was the combination of 300 kgN/ha + 80 kg CaO/ha; d) The averages of the factorial surpassed to the one of the witnesses in most of the variables with the exception of diameter of the fruit and in-house height; e) In the determination of the Optimum Dose of nitrogen based in three points ( 0, 150 and 300 kg/ha ), he observed a linear positive tendency, which is why cultivation can from the point of sight agronomic keeping on answering to the application of this element; f) The Physiological Optimum Dose ( DOF ) for CaO belonged to 86 kg/ha and the Cost-Reducing Optimum Dose ( DOE ) of 48 kg/ha; g) According To the methodology of partial budgets with the treatment 2 ( 150 kgN/ha + 80 kg CaO/ha ) obtained the highest pullback marginal rate themselves.
