Pengaruh Konsentrasi AB Mix Pada Media Tanam Campuran Arang Sekam Dan Cocopeat Terhadap Tanaman Selada (Lactuca sativa L.)

Abstract

Lettuce (Lactuca sativa L.) is a horticultural commodity with promising commercial prospects due to its short harvest period, wide market, and stable prices. BPS data shows that the demand for lettuce continues to rise, surpassing market supply. Nutritional support, particularly through AB Mix, plays a crucial role in enhancing lettuce production. AB Mix contains essential nutrients that promote optimal growth and development in lettuce. This study aims to identify the best AB Mix concentration for lettuce grown on a mixture of roasted husk and cocopeat. The research used a non-factorial Randomized Group Design with five treatments: A (750 ppm AB Mix), B (1,250 ppm), C (1,500 ppm), D (1,750 ppm), and E (2,000 ppm), each repeated five times, totaling 25 treatment units. Data were analyzed using ANOVA and further tested with the 5% DMRT test. The results showed significant differences in plant height, leaf length, leaf width, crown width, root volume, wet weight, and dry weight across treatments. The optimal concentration for the efficient growth of lettuce was found to be 1,500 ppm.
