Abstract

Fertilization is one of the most delicate cultural practices which has direct implications on tobacco yield and quality. Only by controlled application of mineral fertilizers, a high quality and quan- tity of tobacco, suitable for the world market, can be obtained. Fertility of soils is not a constant value. It changes in accordance with cultural practices applied and, therefore, its permanent monitoring and controlling is necessary. For this aim, in the Autumn 2003, 104 soil samples were taken from the region of Radovis to estimate the following elements: humus, carbonates, soil solution pH, total nitrogen, available phos- phorus, available potassium and the content of physical clay. According to the humus and nitrogen supply, these soils are suitable for growing aromatic tobaccos of the type Yaka. The supply of phosphorus is extremely low to low and that of potassium is good, while Ph reaction is neutral, moderately acid to low acid. Based on these data, for production of good quality tobacco in this region we can recommend the application of mineral fertilizer NPK 8:22:20, in a rate of 300-400 kg/ha, depending on soil fertility. In soils with high potassium supply, fertilization with potassium can be escaped for a few years and complex fertilizer N:P 16:32 can be applied, in a rate of 150 -250 kg/ha.
