Cím:	Effect of Climate Change and Crop-Year on the Yield and Nitrogen Fertilizer Efficiency in Winter Wheat (Triticum aestivum L.) Production / Peter Pepó
Dátum:	2020
Megjegyzések:	Abstract Winter wheat has a decisive role in Hungarian crop production. The sowing area of wheat varies between 1.0 and 1.2 million ha. The national average yield of wheat was 5.0?5.5 t ha?1 in the 1980s but nowadays the country average one varies between 3.0 and 5.0 t ha?1 depending on the climatic factors of crop-year. The total Hungarian Nitrogen (N), Phosphorus (P) and Potassium (K) fertilizer usage was 250?300 kg ha?1 in the 1980s, but it has decreased to 80?100 kg ha?1 presently. Results of our long-term experiments on chernozem soil proved that the crop-year and the climatic factors (mainly the water supply: quantity of rainfall XE "rainfall" and its distribution) have strong effects on the natural nutrient utilization, yield surpluses of N-fertilization, the maximum yield and the optimum N(+PK) fertilizer doses of different winter wheat genotypes. The nutrient (mainly nitrogen) utilization of winter wheat was modified by abiotic (climatic factors) and biotic (leaf-, stemand spike-diseases) stresses. In the optimum crop-year and agro-technical models, the maximum yields of winter wheat varied between 7 and 9 t ha?1. In unfavourable climatic and agronomic conditions, the yields of winter wheat dropped to 3/6 t ha
