The Effect of Bulb Seed Diameters and KCl Fertilizer Dosage on Growth and Productivity of Bima Varieties of Shallot (Allium ascalonicum L.)

—Shallot is one of valuable horticulture commodities that planted almost in Indonesia. One of the advantages in shallot cultivation is decreasing of shallot productivity although fertilizer was given in shallot cultivation. The purpose of this research was to determine the effect of diameter of bulb shallot (bulb size) and KCL fertilizer dosage on growth and productivity of shallot Bima cultivars. This research was conducted in Mei to July 2019 at Widasari district, Indramayu regency, West Java. Randomized block design with two factors, diameter of shallot bulbs and KCL fertilizer dosage was used to arrange the treatment in field. The result showed that the utilization of large seed bulb of shallot has highest number in growth and yield response including plant height, number of leaves, number of tiller, wet and dry yield bulb.
