Effect of Several Types and Doses of Organic Fertilizer on The Growth and Production of Pakcoy Plant (Brassica chinensis)

Abstract Pakcoy is one of the Brassicaceae family’s vegetable plants which is currently highly very popular with the public. Pakcoy production in West Sumatra continues to decline due to the continuous use of inorganic fertilizers. Chicken manure is a particular kind of organic fertilizer alternative that can replace inorganic fertilisers. This study’s objective is to ascertain the impact of various organic fertilizer types with different bio activators and doses on development and plant production. Experiment was compiled utilizing a factorial pattern set up in a Randomized Block Design (RBD) with the first treatment of organic fertilizer varieties, namely: Chicken manure (CM), Chicken manure with N21 bio activator (CMN), and Chicken manure with banana weevil LMO bio activator (CMM). The second treatment of doses of organic fertilizers: 5, 10, 15, and 20 t.ha −1 . The treatment combined was repeated 3 times, for a total of 36 experimental units and each experimental unit had 9 clumps of plants. The measured value was examined using the STAT program and followed by the DMRT test. The findings indicated that the application of chicken manure + banana weevil LMO gave the best results toward leaf length, leaf width, canopy width, number of leaves, wet weight, and dry weight pakcoy plant
