Sažetak
The yield of arable crops may be influenced by many factors such as water, temperature and nutrient deficiency. The winter wheat (variety Zitarka) field trials were set up in the autumn of 2002 on silty loam stagnic luvisol at site Donji Miholjac and loessive pseudogley at site Krizevci in continental Croatia. The results of the triennial experiments show big influence of climate conditions (year) and sites on usage of nutrients from fertilizer and forming of wheat yield. The highest fertilization dosage (N5P2K2) in average almost doubled the total mass yield and wheat grain yield comparing to the control. Fertilization with nitrogen, which according to the phosphorus input in average increased the grain yield 3.5 times and above ground mass yield 10 times, and according to the potassium 4 and 20 times, had the biggest influence on both yields. Non appropriate fertilizer use may result in non sustainable plant nutrition.
