Performance of shallot (Allium cepa var. ascalonicum) derived from true seed under a dry condition area

Abstract

To reduce the dependence of bulbs as planting material, the innovation technology of shallot (Allium cepa var. ascalonicum) cultivation with using true shallot seed (TSS) as planting material was tried. Four cultivars namely Bima Brebes, Trisula, Tuk Tuk, and Sanren were planted at Laleten Village, Malaka District, from April to December 2018. TSS seedlings were raised with a 10x15cm planting spacing or 2,000 plants/30m−2. The aim of this research was to evaluate the using TSS at the shallot cultivation in the areas where the farmers have never carried out such technology. The vegetative growth of all varieties is not significantly different. The productive plants are range from 70 to 75% of population, which the highest was Trisula. The bulbs number/plant highest in Bima Brebes. The number and fresh bulbs weight/bed were 2,293 – 4,601 bulbs and 19.8 – 31.5kgs, respectively. Bulbs weight loss during storage was about 48-65%, which the driest bulbs was Tuk Tuk. The estimated of fresh production was only 5.28 to 8.41 tons/ha. It means that in dry conditions with farmers have not mastered yet on shallot cultivation by using TSS as planting material, the productivity only reaches 20-40% of the production capacity.

Growth and yield response of shallot (Allium ascalonicum L. var. Tuktuk) from different source materials applied with liquid biofertilizers

“…This adds to the production costs for maintaining plants, even though the lower yields as shown by the results of this study. The growth of seed origin plants is slower than the origin of the bulbs because the bulbs have nutrient reserves that can be absorbed by plants in their initial growth, while seedlings of seed origin plants do not have food reserves so they must look for themselves from the surrounding environment (Devy et al 2020;Hantari et al 2020).

The Effect of True Shallot Seed (TSS) Varieties and Population on Growth and Bulb Yield

“…The research was conducted at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. This area is located at an altitude of 55 m above sea The Effect of True Shallot Seed (TSS) Varieties and Population on Growth and Bulb Yield level and has a monthly rainfall of 0 to1,435 mm, an average temperature of 24-34C and a dry tropical climate (Devy et al 2020).…”

“…Nevertheless, its productivity is still low (about 8 tons/ha). In dry area of Laleten, Malaka District, the estimated productivity of fresh bulbs per hectare for Tuk Tuk, Sanren, Bima Brebes and Trisula varieties of TSS were 5.28, 6.05, 8.41 and 7.97 tons, respectively (Devy et al 2020). Therefore, implementation of innovation technology such as a superior variety, optimal nutrition, control of pests and diseases optimally and increasing the density of plants are required (Awas et al 2010;Biru 2015;Shimeles 2014).…”

Pengaruh Lama dan Ruang Simpan terhadap Perkecambahan Benih True Shallot Seed (TSS)

“…S. P. Rahayu et al, 2019). Petani kini mulai banyak yang menggunakan TSS sebagai benih baik di pulau Jawa (Makhziah et al, 2019;Pratiwi et al, 2018;Roessali et al, 2019) atau di luar Jawa antara lain Sulawesi (Maintang et al, 2019;, Nusa Tenggara Timur (Devy et al, 2020) dengan teknis budidaya yang sesuai dengan lingkungan setempat atau yang dimodifikasi.…”
