THE USE OF BLACK SILVER PLASTIC MULCH AND TRICHOCOMPOST ON THE GROWTH AND PRODUCTION OF LONG BEANS (Vigna sinesis L.)

Abstract

Long beans (Vigna sinesis L.) are ranked eighth out of 20 vegetable varieties consumed in Indonesia. One of the advantages is a good source of vitamins and minerals. The study aims to determine the effect of black plastic mulch and trichocompost on long bean production. The study was conducted in the experimental field of the Faculty of Agriculture, Batu Plat Village, Kupang City from September to October 2024. The research design used a Randomized Block Design (RAK) factorially consisting of 2 factors, namely factor 1 = Mulch (M), M0 = Control, M1 = Silver Plastic Mulch, Factor II = Trichocompost (T), TO = Control T1 = Trichocompost 10 tons / ha or equivalent to 3 kg plot-1, T2 = Trichocompost 20 tons / ha or equivalent to 6 kg plot-1, T3 = Trichocompost 15 tons / ha or equivalent to 9 kg plot-1. Results: The length of long bean plants was greatly influenced by the application of trichocompost and black plastic mulch. Trichocompost dose of 25 tons/ha, or 9 kg plot-1, and plastic mulch (T3M1) produced a plant length of 167.83 cm, 168.53 leaves, 23.4 pods, pod weight of 162.13 grams, and plant stump weight of 182.53 grams. The best results for long bean production were obtained when trichocompost of 25 tons/ha, or equivalent to 9 kg plot-1, was combined with plastic mulch.
