THE RESPONSE OF SOME WHEAT QUALITY INDICES TO FOLIAR FERTILIZATION

Abstract

A good soil fertility program requires vision and planning. Achieving cost-effective and efficient wheat production involves providing sufficient amounts of plant nutrients when and where the crop needs them. Wheat is a particularly demanding crop for fertilization, which reacts positively to the application of fertilizers. Cereal consumes moderate amounts of nutrients due to the fact that its roots explore a smaller volume of soil. The influence of foliar fertilizers for different crops is diverse and depends on the plant species. Foliar application can guarantee better availability of nutrients to crops and also achieve higher yields. Nutrient concentration and temperature should be optimal to avoid leaf burn, and the fertilizer source should be water soluble to be more effective. The role of macro and microelements is crucial in plant nutrition and in obtaining higher yields. Nitrogen (N), phosphorus (P) and potassium (K), the primary essential macronutrients, are of primary importance in crop nutrition. Nitrogen is the primary constituent of proteins and therefore of enzymes. Phosphorus is involved in almost all biochemical processes as part of energy-carrying compounds. This work follows the evolution of some wheat quality indices under the variation of nitrogen content.
