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 types of fertilizers (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 treated according to the experimental design; each treatment was replicated three times. The results showed that there was an interaction between type of fertilizers and soil moisture in affecting fruit sugar content and fruit diameter. Sugar content of tomatoes harvested from plant treated with AB Mix and grew under 30% soil moisture level was not significantly different from tomatoes 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. Tomato plants treated with LOF and grew under 30% soil moisture level significantly produced smaller fruits 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. The percentage of tomatoes infested by fruit rot was not significantly affected by type of fertilizers and but affected by soil moisture. The lowest fruit rot intensity occurred on plant grew under 30% soil moisture level. Keywords: inorganic fertilizer, liquid organic fertilizer, quality, soil moisture, tomato
