<![CDATA[Utilization of Lamtoro Leaf Green Manure (Leucaena Leucocephala) and Banana Weevil Liquid Organic Fertilizer on Growth and Production of Long Beans (Vigna Sinensis L). Under the guidance of Mr. Ir.H.Gusmiezal,MP as chairman and Mr. Ir .H.Abdul Rahman, MS as a member. The study was conducted in the experimental garden of the Faculty of Agriculture, University of Medan Area. Percut Sei Tuan District, Deli Serdang Regency, North Sumatra in July-October 2021.

Parameters observed were: Plant height (cm), Stem diameter (cm). Flowering age (days). Production per plant (g). Production per plot (kg). The results showed that the green manure of lamtoro leaves showed significant results in the L3 treatment with a dose of 30 tons/ha (4.32 kg/plot) and for the application of liquid organic fertilizer the Banana Bonggol gave significant results in the P3 treatment with a concentration of 15%. For the combination of the 2 treatments, the real treatment was L1P3 (Lamtoro application with Banana weevil POC).]]>
