For the tomato crop on sandy soils the insurance with nutrients is one of the most important links in the technology. The tomatoes can be grown in open field direct at the ground or with polyethylene mulch. For the fertilization were used 4 types of fertilizers with different concentrations of soluble nutrients elememte (9-45-15, 26-15-12, 20-20-20 and 15-15-30). The fertilizers were applied during the growing season depending on the requirements of plants. Were used 2 agrofunds in the NPK using the 15-15-15 complex chemical fertilizer. Tomatoes in culture with polyethylene mulch uses the chemical fertilizers more effectively than culture direct at the ground, in all variants of fertilization the largest production was obtained in the crop with mulch. At the culture without mulch highest production was achieved in the variant fertilized with soluble fertilizer dose of 50 kg/ha on the agrofond N 100 P2O5 100 K2O 100 (38.1 t/ha) and culture with mulch recommend fertilizing with 25 kg/ha soluble fertilizer on the same agrofond (38.3 t/ha). Increasing doses of soluble fertilizers at crop with mulch is not justified in terms of yields achieved. [ABSTRACT FROM AUTHOR] |
