PEMANFAATAN LIMBAH AIR KELAPA UNTUK MENINGKATKAN AKUMULASI FOTOSINTAT DAN LUAS DAUN BIBIT KAKAO (Theobroma cacao L.)

Abstract

Indonesia is one of the cocoa producers in the world, but Indonesia's cocoa production is still below the Ivory Coast and Ghana. One of the ways to increase production is by using good seeds. Good seeds can be obtained with optimal maintenance. Through the use of coconut water as waste containing nutrients and growth hormones, it is expected to increase growth components such as dry weight and leaf area. Good seeds when planted in the field will produce well too. The experiment was carried out in April – August 2021, in the Ciparanje experimental garden, Faculty of Agriculture, Padjadjaran University, Jatinangor with an altitude of 725-800 masl. The experiment used a Randomized Block Design (RAK) with ten treatment combinations and was repeated three times, each treatment consisting of four plants. The treatments tested were control, urea 2 g/polybag, administration of coconut water through plants at 100%, 75%, and 50% calibration doses, administration of coconut water through soil 100%, 75%, and 50% dose of field capacity, administration of coconut water. through plants 25% calibration dose + through soil 25% dose field capacity, and giving coconut water through plants 50% calibration dose + through soil 50% dose field capacity. The experimental results showed that the best response on dry weight and leaf area of ​​cocoa seedlings was caused by giving coconut water through plants with 50% calibration dose.
