Agronomic response of kangkung plants typical of Lombok Island with a hydroponic system treated with Trichoderma bionutrients

Abstract

Abstract The kangkung (Ipomoea aquatica Forsk) is water spinach typical of Lombok Island, Indonesia with a crunchy texture and distinctive taste. It is very easy to be cultivated in the home garden organically in soil media, also to be planted hydroponically and aquaponically. Hydroponic system cultivation is the cultivation of plants by utilizing water without using soil with an emphasis on meeting the nutritional needs of plants. One of the nutrients that has good prospects is the Trichoderma bionutrient which is made from a mixture of bioactivator and biourin. The purpose of this study was to determine the agronomic response of water spinach plants typical of Lombok Island with a hydroponic system treated with Trichoderma bionutrients. The study used an experimental method carried out in a plastic house with a hydroponic system. The study used a completely randomized design with hydroponic nutrition treatment consisting of 6 levels, namely: without bionutrients, with bioactivator bionutrients, with biourin bionutrients, with a mixture of bioactivator and biourin, with AB mix nutrition, with a mixture of Trichoderma bionutrients and Ab mix nutrients. Each treatment was repeated 4 times so that there were 24 experimental units. The results showed that the treatment with a mixture of bionutrients with a mixture of bioactivators and Trichoderma biourin was as good as AB mix nutrition in promoting growth and wet weight of kangkung typical of Lombok Island.
