LETTUCE PLANT-GROWTH WITH THE USE OF SOIL CONDITIONER AND SLOW-RELEASE FERTILIZERS

In two pot experiments, lettuce plant growth under different soil-water conditions was examined. In the first experiment, the effect of soil conditioner in combination with slow-release and water-soluble fertilizers was considered. In the second experiment, lettuce plant resistance in moisture stress with the use of a soil conditioner was evaluated. The first experiment showed that the use of soil conditioner with slow-release fertilizers gives greater yield than the use of water-soluble fertilizers alone. The second experiment showed that there is no difference on the yield and quality of lettuce plants between the trials until the irrigation time of twenty days.
