Respons growth and production of shallot (Allium ascalonicum L.) on Complementary Liquid Fertilizer (CLF) dosage and interval of application time

Abstract

Shallot is one of the agricultural commodities whose production needs to be increased in the national food security program framework. One effort to increase yield is by conducting cultivation techniques including, fertilization. The study was objective at determining the dose of complementary liquid fertilizers (LCF) and interval application time and their interactions to increase the growth and yield of shallots. The study was conducted in Lampoko Village, Barebbo District, Bone Regency, in April-June 2018. The experiment used a factorial randomized block design with two factors. The first factor was the CLF dose at three levels (1,0, 2,0, and 3,0 ml L−1) and the second factor was an interval of application time at three levels (every 5,7, and 9 days). The results showed that the treatment of CLF dose significantly affected plant height and number of leaves. The treatment of the interval of application time significantly involves the number of bulbs, bulbs’ diameter, fresh bulbs weight, and dry bulbs weight. In general, the best growth and production of shallots were obtained in the treatment of LCF with a dose of 2,0 ml L−1 at an interval of 5 days for once application.
