Özet
<p>Turkey produces 7 million tons of tomatoes in 160 thousand ha of land per year and occupies 7 % of the world production. Of the production, 73% is consumed fresh, 25 % is processed and 2 % is exported. According to the 1998 statistics, 1.011.361 t of total 8.200.000 t tomato produced in Turkey is production under greenhouse conditions. Tomato production with share of 51 % is the first order in the vegetable production. </p><p>The objective of the study was to examine the effect of K fertilization on greenhouse tomato yield and quality parameters. Enhanced levels of K (0-120-240-360 kg K2O ha-1) and required amounts of N (240 kg N ha-1) and P (120 kg P2O5 ha-1) were applied ⅓ as a base and the remaining as side dressing. </p><p>Results showed that the highest dose of K yielded the highest. Similarly the highest K dose was also positively effective on some fruit parameters as average fruit weight, fruit width, ten fruit weight and acidity. On the other hand, 240 K2O ha-1 dose had positive impacts on total soluble solids, Vitamin C and color of fruits.</p>
