Increasing Shallot Production in Marginal Land Using Mulches and Coconut Husk Fertilizer

Abstract

The study aimed to obtain the type of mulch and the doses of liquid organic fertilizer proper waste coconut husks in modifying microclimate around crops to obtain the maximum yield of shallot in the dryland. The research was used a factorial randomized complete block design consisting of two factors. The first factor consisting mulches, M1 = silver-black plastic mulch and M2 = straw mulch. The dose of liquid organic fertilizer from coconut husks was the second factor. It is consisting of S0 = without fertilizer, S1 = 500 L ha-1, S2 = 750 L ha-1 and S3 = 1000 L ha-1. The results showed that the application of a combination of mulch and liquid organic fertilizer coconut husk waste significantly affected plant height, number of leaves per plant, number of tillers, and the bulb yield. Straw mulch with coconut husks waste dose of 1000 L ha-1 resulted in plant height, number of leaves per plant, number of tillers and highest bulb yield compared with other treatments. The highest bulb yield was obtained with 9.63 t ha-1.
