Cím:Evaluation of the interaction between nutrient supply and water management on the basis of a long-term experiment in Debrecen / Nagy János
Megjegyzések:The great variability of the climate is one of the biggest risk factors for production and producers have to continuously consider this factor in modern agriculture. In the last one hundred years, the proportion of droughty and extremely wet years significantly increased. Both have a negative effect on field crop production and its predictability. Barrov et al. (2000) reported a similar tendency throughout Europe on the basis of changes in the quantity of precipitation in the winter (+0.4 to +3.6%) and summer (?0.5 to +3.7%) periods between 1961 and 1990. Berényi (1956) stated that the quantity of precipitation is of significant importance, natural water supplies being responsible for 55?75% of the yield. Láng (1976) and Márton (2002) also proved the significant effect of weather on yield. Many researchers found a close correlation between the year effect, the nutrient supplies to the crops and the yield (Kádár, 1992; Tóth et al., 2002; Nagy, 2008). Berzsenyi and Győrffy (1997) stated that lower fertilisation doses led to higher yield stability in dry years, whereas higher doses resulted in greater stability in wet years.
