ABSTRACT

This study aimed to determine the best substrate and nutrition as well as their interaction on the growth and yield ofchilies. Hydroponic substrate is a modern farming system using media aside soil such as husk, broken tiles, broken bricks, palm fiber, sand, and steamed rice husk. Standard nutrition as a main source of nutrients in a hydroponic substrate, the addition of NPK nutrients used to support the standard nutrient for growth and yield of chili. This study aims to determine the best substrate and nutrition as well as their interaction on growth and yield of chili. Research conducted at screen house Faculty of Agriculture, Sebelas Maret University using a completely randomized design with 2 factors, substrates and nutrients. The data analysis used F test level of 5% and if it’s significant continued with DMRT (Duncan Multiple Range Test) level of 5%. The results showed that treatment sand substrate and nutrients AB mix with the addition of NPK showed the best results and were able to increase plant height, number of leaves, number of flower, fruit weight and number of fruit.

Key words: husk, broken tiles, broken bricks, palm fiber, sand, NPK
