THE ECONOMIC EFFECT OF FERTILIZATION TO INCREASE THE PRODUCTION AND IMPROVE THE QUALITY OF TOBACCO

Combination utilization of nitrogen- phosphates and potassium fertilization in the studied proportions has a direct impact on the production increment and in the amelioration of the quality of the tobaccos. Fertilization maintains a weight proportion between the carbohydrates and proteins, which should be 1.5 ? 2 favouring the carbohydrates. The best proportion is in the variant N40, P60, K40-60. This study conducted gives the possibility of an economic evaluation of the way of use, time and the combination of nutritional chemicals in tobacco plants. Also through these nutritional interventions guaranteed quality of tobacco production.
