Abstract

This research aimed to study the quality of tomato grew under different fertilizer applications and soil moisture levels. The green house experiment was set in a Randomized Completely Block Design. The treatments were various type of fertilizer (Liquid Organic Fertilizer/LOF, inorganic fertilizer/AB Mix, LOF+AB Mix) and different soil moisture levels (30%, 45%, 60%, 75%). Tomatoes were planted in polybags in a green house and with treatments according to the experimental design, each treatment were repeated three times. There was an interaction between type of fertilizer and soil moisture in affecting fruit diameter and fruit sugar content. The percentage of fruit infested by fruit rot was not significantly affected by type of fertilizer and soil moisture. The results showed that tomato plant treated with LOF and grew under 30% soil moisture level significantly produced smaller fruit than those treated with AB Mix only or AB Mix+LOF grew under 45%, 60% or 75% soil moisture except those treated with AB Mix+LOF grew under 45% soil moisture. Sugar content of tomato fruit harvested from plant treated with AB mix and grew under 30% soil moisture level was not significantly different from tomato grew under 45% soil moisture level and treated with AB Mix or LOF, but the sugar content was significantly higher than those grew under 60% or 75% soil moisture level treated with different type of fertilizer.
