CLOROFILA a E b DE TOMATEIRO TRATADO COM SILICATO DE POTÁSSIO E FUNGICIDA.

This work to evaluate the effect of foliar application of Potassium Silicate (K2SiO3) and the number of fungicide applications on the content of chlorophyll and the tomato. The experiment was performed in Uberlândia, Minas Gerais, with a randomized blocks in a factorial 4 x 2 with four doses of Potassium Silicate (K2SiO3 - 12.2% Si, 15% K2O), (0, 0, 2, 0.4 and 0.6 mL 100L-1 sauce) and two managements fungicide (two three weekly applications) with four blocks. The potassium silicate was applied weekly from transplanting to the date of the last harvest, totaling 15 applications. We evaluated the levels of chlorophyll a, b and a / b ratio in the upper and lower third of the plant; the development of production and productivity and fruit classification. The K2SiO3 doses provided increases in the chlorophyll content; the contents of chlorophyll b and a / b ratio did not show significant variation; with three weekly fungicide applications were better classification of fruit, but with two weekly applications it had increased productivity; K2SiO3 doses gave productivity increases with the dose of 0.38 U 100L-1 gave the highest production of fruits and G 100L-dose 0.33 1 Total fruits.
