effect of water-stress on the mineral nutrition of fruit plantations

Besides agro-techniques the climatic conditions pla y an important role in agricultural production. Wea ther extremes are significant hazards to many horticultural regions a ll over the word. It has a profound influence on th e growth, development and yields of a crop, incidence of pests and diseases, water needs and fertilizer requirements in terms of differences in nutrient mobilization due to water stresses. Nowadays, the weather extremes cause more and more problems and significant hazards to many horticultural regions in Hungary. The aim of this study is to explore the problems of nutrient uptake followed from climatic anomalies a nd response it. In this study we focus on water supply problems (water-stress). Reviewing the effects and nutrient disorders caused by climatic anomalies, the following statements ca n be taken: • Nutrient demand of trees can be supplied only under ev n worse conditions. • The most effective weapon against damage of climati c anomalies is preventative action. • Proper choice of cultivars, species and cultivation should provide further possibilities to avoid and moderate the effects of climatic anomalies. • Fruit growing technologies especially nutrition sho uld be corrected and adjusted to the climatic event s as modifier factors. • The role of foliar spraying, mulching and fertigati on/irrigation is increasing continuously. • Urgent task of the near future is to correct and ad just the tested technologies of fruit growing accor ding to these climatic events as modifier factors.
