The Economic Effect of the Fertilization of the Increment of the Production and on the Amelioration of the Quality of the Tobacco

Abstract

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 N40P60K40-60. Tobacco reacts toward soil fertility and the fertilization by assimilating nutrient elements, which are in them to complete its biological indispensable requirements. It has been determinate that 1 kv tobacco product should assimilate 4.1 kg N,1.6 kg P and 7.0 kg K. The augmentation of the production quality is very important in the tobacco cultivation because on this depends its use value, to be as much aromatic as possible, testily and as little as possible harmful for the consumer. In this study was proved the combination of doses of nitrogen, phosphate and potassium fertilization in each other’s background, in determined proportion among them. The doses of nitrogen fertilization from 40kg/ha to 90kg/ha active nitrogen were studied in the background of 60kg/ha phosphor, 60kg/ha background of 40kg/ha active nitrogen and 60kg/ha active potassium; phosphor doses of 40-90kg/ha are also studied in details, while the effects of potassium fertilization was determinate in the background N40 P60kg/ha.
