POTENSI EKSTRAK DAUN KIRINYUH (Chromolaena odorata L.) SEBAGAI BIOSTIMULAN TERHADAP PERKECAMBAHAN KACANG TANAH (Arachis hypogaea L.)

Abstract

Peanut production in West Kalimantan which tends to decline has not been able to keep up with the needs of people. Seed quality is the problem that often faced by peanut farmers. Secondary metabolites especially flavonoids and terpenoids contained in plant extract can be used as biostimulants. This study aims to determine the effect of kirinyuh (C. odorata) extract and to determine the optimal concentration of kirinyuh extract on the quality of peanut germination and growth. This research was conducted from July to August 2022 at the Biology Laboratory and Greenhouse of the Department of Biology, FMIPA, Tanjungpura University, Pontianak. This study used a completely randomized design (CRD) with 11 levels concentration of extract kirinyuh (0; 10; 20; 30; 40; 50; 60; 70; 80; 90; dan 100 mg/L). The results showed that 20 mg/L of extract kirinyuh was the most optimal concentration for germination parameters such as emergence time of epicotyl, emergence time of leave, leaf opening time and 50 mg/L extract kirinyuh was the most optimal concentration for growth parameters such as plant height
