The Engineering Of Planting Media And Ab Mix Nutritional Concentration To Improve Tomato Agronomic Characteristics Hydroponically

Abstract

The decline in tomato production in Indonesia in recent years has become an obstacle in its cultivation. Unstable soil and climate
problems can reduce the quality and quantity of this crop. Efforts to increase production have been made through the
improvement in the hydroponic cultivation system. The study was conducted to determine the effect of planting media and
nutrient concentration of AB Mix to improve the agronomic characteristics of tomatoes by hydroponic wick system. The study used
a factorial completely randomized design (CRD) consisting of 2 treatment factors, namely the planting medium combined with the
nutrient concentration of AB mix. The planting medium consists of: M1 = 50% baglog waste + 50% sand, M2 = 100% baglog waste
and M3 = 100% sand, while the concentration of AB mix nutrients consists of: K1 = 1000ppm, K2 = 2000 ppm and K3 = 3000 ppm.
The research results showed that the best combination of planting media and nutrient concentration of AB mix at plant height
variables was on the planting medium addition of 50% baglog waste + 50% sand with a nutrient concentration of AB mix of 3000
ppm. The addition of 100% sand and 3000 ppm AB mix nutrient concentration each can increase plant growth variables. While the
addition of 1000 ppm AB mix nutrient concentration can increase the number of fruit by 24,89/plant and can increase fruit weight
from around 103g/plant to 648,30 g/plant for 3 harvests.
