Mulching Effect on Growth and Yield of Garlic at Rurukan Village, Tomohon City

Abstract

Abstract Garlic production in Indonesia is still not able to supply the public needs, therefor as much as 99 percent of the needs are met from imports. Several cultivation technology innovations which can increase production to help meet domestic consumption targets include the use of local varieties, site-specific fertilization, and the use of plastic mulch. The purpose of this study was to determine the effect of mulching on the growth and yield of two varieties of garlic (Allium sativum L). The research was conducted in Rurukan Village, East Tomohon District, Tomohon City, with an altitude of 700 m above sea level from April to December 2018. The study used a Randomized Completely Block Design (RCBD) with 4 treatments and 5 replications, namely A (without mulch, Lumbu Hijau) variety; B (without mulch, Lumbuh Kuning variety); C (Plastic Silver Mulch, Lumbuh Hijau variety) and D (Plastic Silver Mulch Lumbuh Kuning variety). The data were analyzed using analysis of variance (ANOVA). If it had a significant effect, then it will be continued with the Ducan Multiple Range Test (DMRT) at 5% level. The results showed that the response of garlic to the variables of plant height (cm), the diameter of tuber/plant (cm), dry weight of bulb (g), and yield (tons/ha) showed different responses, while the number of leaves (strands) of garlic is not significant. Treatment D (Plastic Silver Mulch Lumbuh Kuning variety) was the best treatment for the growth and yield of garlic.
