Cocoa contributes more than USD 700 million to its economy and continues to main tain its prestige through had dedvalue in the national and international market. It is necessary to indicate that, in the case of crops, the circumstance of high nutrient extraction is not compensated naturally, so itisnecessarytoreturnthenutrientstothesoilthroughedaphicfertilization. The objective of paying a crop is too tain high yields and quality in the harvested. Additionally, fertilization muster present a positive cost-benefit ratio, that is to say that the amounts in vested in fertilization are returned by the profits obtained in the in crease in production and / or quality. It is necessary to develop a soil analysis and by studying the soil, to carry out a fertilization program with the correct doses, nutrient swith a high percentage of efficiency and at the same time to present a positive cost-benefit ratio. Thefertility of thesoil and the dynamics of the elements are related to nutritional absorption, which can vary basedon the phonological state of th cocoa plant. In the San José farmthey explained that cocoa in the nurse rystage needs more potassium, phosphorus, nitrogen and calcium and in its production stage it is essential to incorporate elementssuch as manganese and sulfur. In the same way, in every crop, symptoms of nutritional deficiency in the crop can be presented, either due to losses of nutrient duet oleaching, untimely fertilization, low doses with respect to the nutritional requirement of cocoa and can influence competition of the crop. It is necessary to evaluate the physiological behavior of the cocoa plantation based on different doses of fertilizers in order to determine they ield and susceptibility to Monilla and witch broom diseases. Carry out studies on the dynamics of absorption in cocoa crop sunder irrigation and dry conditions, to determine the use of macro and microelement savailable in the soil. |
