Quantity and Quality of Shallot (^{Allium ascalonicum} L.) as Influenced by Water Hyacinth Compost on Fluventic Eutrudepts

Abstract

One of the problems with Fluventic Eutrudepts is that it has a low level of soil fertility because the soil surface is effortless to wash. The solution to this problem is the addition of one or more available nutrients to optimize soil fertility so that it can increase quantity and quality plant. This experiment aims to find the best dosage of water hyacinth compost and N, P, K, S fertilizer against changes in sulfur, quantity and quality of Batu Ijo Variety of shallots. This experiment was carried out at the Laboratory of Soil Chemistry and Plant Nutrition Experimental Garden, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, Sumedang from February to August 2020. The research approach used was a randomized block design (RBD) consisting of seven treatments and repeated four times, namely: control; N, P, K, S recommendations (¾, 1); dosage of fertilizer N, P, K, S (¾, 1); and the dosage of water hyacinth compost (½, 1, 1½). The results showed that the treatment dose of 25 t/ha of water hyacinth compost and 150 kg/ha Urea, 225 kg/ha SP-36, 150 kg/ha KCl, 375 kg/ha ZA was able to provide the best effect in increasing sulfur content, quantity, and the quality of shallots at Fluventic Eutrudepts.
