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.
Highlights
Inceptisols from Jatinangor is included in the Udepts suborder, the Eutrudepts great group and the Fluventic Eutrudepts sub-group
Continuous application of inorganic fertilizers can result in decreased land productivity, one way to overcome the other impacts that will arise from the use of inorganic fertilizers is through compost
The advantage of compost made from water hyacinth is that the American Journal of Biological and Environmental Statistics 2020; 6(3): 50-57 elemental content of sulfur is higher than compost with a variety of raw materials [11, 27, 36]
Summary
Inceptisols from Jatinangor is included in the Udepts suborder, the Eutrudepts great group and the Fluventic Eutrudepts sub-group. Based on the results of the preliminary soil analysis on Inceptisols, the chemical properties are less fertile Several chemical properties which are indicators of soil fertility include slightly acidic pH content of H2O (6.48), low total N (0.19%), medium available P (10.72 mg/kg) and medium K-potential (31.54 mg/100 g), SO42- very low (5.11 mg/kg), low Corganic (1.83%), and medium Cation Exchange Capacity (CEC) (21.96 mmol/kg). It is necessary to add one or more available nutrients to optimize soil fertility so that it can increase quantity and quality plant. The nutrient content of water hyacinth compost is relatively high, namely N of 1.68%, P of 3.69%, K of 2.50%, organic-C 31.92%, C/N ratio of 19, and S of 900. The advantage of compost made from water hyacinth is that the American Journal of Biological and Environmental Statistics 2020; 6(3): 50-57 elemental content of sulfur is higher than compost with a variety of raw materials [11, 27, 36]
