Abstract

. Water hyacinth (Eichhornia crassipes) is a source of organic matter that can be used as compost to improve the soil quality and productivity of shallots. Shallots are horticultural commodities that have various benefits. Inceptisol soils dominate Indonesia, with an area of 37.5% of Indonesia's land area but have low soil fertility. Soil fertility can be increased by optimal fertilization. This experiment aimed to determine the dose of water hyacinth compost and nitrogen (N), phosphor (P), potassium (K), sulfur (S) fertilizer which gave the best effect on increasing available S, S uptake, protein content, and yield of shallots. The experiment was conducted from July to October 2021 at the Experimental Garden of the Laboratory of Soil Chemistry and Plant Nutrition, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor. The experiment used a Randomized Block Design, consisting of seven treatments repeated four times. The recommended fertilizer doses used are 200 kg Urea, 500 kg ZA, 300 kg SP-36, and 200 kg KCl. The compost used was water hyacinth compost at a 25 t/ha dose. The results of this experiment showed that the treatment of ¾ compost + ¾ doses of N, P, K, and S was the best in increasing available S (26.79 mg kg-1), S uptake (7.03 mg/plant), protein content (0.95%), colors and shallot yield (number of tubers, fresh weight, and dry weight) on Inceptisols from Jatinangor.

Abstract

Sustainable rice farming is increasingly threatened by declining soil fertility, excessive reliance on chemical fertilizers, and environmental degradation from intensive agricultural practices. There is an urgent need for innovative organic fertilizer products that combine organic materials with macro and micronutrient enhancements to restore soil health effectively. This research aimed to evaluate the effect of organic plus fertilizer (OPF) as a sustainable soil amendment to improve soil nutrient status, increase paddy productivity, and enhance overall soil health. The experiment was conducted using a Randomized Block Design (RBD) with nine treatments: one recommended OPF dose, six combinations of NPK (75 – 100%) and OPF (75 – 150%), one recommended conventional NPK dose, and one control. Variables observed included plant growth, yield, and yield components, total soil nitrogen, and plant uptake of N, P, and K. Results indicated that OPF combined with NPK significantly increased plant height (29.13 – 31.38%) and number of panicles (57.89%) compared to the control. Nutrient uptake improved for nitrogen (23.68%) and potassium (15.96 – 21.28%), although no significant improvement was observed for phosphorus. Yield parameters showed an 81.97%–118.50% increase over the control. The combinations of 75% NPK + 150% OPF, 100% NPK + 75% OPF, and 100% NPK + 100% OPF produced taller plants, higher yields, greater nutrient uptake, and lower residual nitrogen in the soil. For optimal rice yield and soil health, integrated application of OPF with either a full or 75% NPK dose is recommended.
