| Abstract:
It is a well-known fact that processing tomatoes are high-nutrient crops and that one of the bases for successful cultivation is optimal nutrient supply. The aim was to assess the effects of various nutrient supply methods to achieve that was carried out in a two-year field experiment on sandy soil with extremely low humus content. Were involved in the investigation of the yield of marketable tomato fruits and one of the relevant parameter for processors what is soluble solids content. It is considered a traditional nutrient supply and soil improvement process for mixing dairy farm manure with soil during the autumn period, which was supplemented with additional large amounts of fertilizer treatments in the next vegetation season. However, the current situation is that of cow farm manure is inhomogeneous quality, so standard deviation is quite unequal, as well as dispensed many seeds of dangerous weed species and in some cases trash with manure. Because of these negative factors, tomato farmers prefer to use chemical fertilizers that are unfavorable for the soil during the long production period. Therefore, an alternative solution is tested for the precision supply of granulated organic fertilizers in early period of tomato growing season. With this provided natural nutrient base for the tomato seedlings, and then continued to nutrition with chemical fertilizer means for supply same amount of macronutrients. Results suggest that processing tomato production with granulated organic fertilizers nutrient supply method competitive to chemical fertilization on sandy soil. | |
