Abstract
Climate change leads and increase the food risky because it is hard to predict the timing or severity of its occurrence, and hydroponics is a method to overcome this problem. This research was held in the green house located at Sebelas Maret University, Indonesia, from October 2016 until March 2017. This study aimed to assess the effects of using some substrates on growth and yield of the hot pepper plant. The experiment was arranged in Randomized Complete Design with single factor. The factor was kind of substrates consisted of 6 levels, i.e.: husk charcoal (as control), steamed husk, cocopeat, combination of husk charcoal + zeolite (1:1, v/v), steamed husk + zeolit (1:1, v/v), and cocopeat + zeolite (1:1), v/v). Data were analyzed using Anova and HSD test at α=0.05. The results showed that substrates effected the number of leaves, chlorophyll content, root volume, dry weight, number of fruit and total fruit weight.
