“…Ammonium sulfate is a nitrogen fertilizer that contains sulfur (21%) (Berhe et al, 2019). Elwan and Elhamahmy (2015) reported that combination of UreaZA fertilizers had a positive interaction effect on plant growth. UreaZA fertilizers contain N nutrient needed for plant growth and photosynthesis.…”

Basil is a plant that can be cultivated in Psamment (coastal sandy soil). Basil requires nitrogen (N) and sulfur (S), so the N-S balance is needed to obtain optimal results. Psamment contains low colloid, causing nutrients to be barely bound and easily lost. Zeolite and biochar can be a solution. This study aimed to determine the composition and frequency of fertilization, as well as the use of soil amendment for basil growth. This research consisted of two interrelated studies arranged in a Randomized Complete Block Design. The research was conducted in Bugel, Panjatan, Kulon Progo, and the analysis was performed at the Soil Department Laboratory, Faculty of Agriculture, Universitas Gadjah Mada. The first study consisted of two factors, namely Urea-ZA composition (0:0, 60:40, 70:30, 80:20, 90:10, and 100:0) and frequency of fertilization (every 1 and 2 weeks). The application of Urea-ZA (80:20) gave the best fresh-dry weight, N-S content, and N-S uptake of basil, and this result was used as the reference for the second study. The second study consisted of two factors, namely Urea-ZA fertilizer doses (50%, 75%, and 100%), and types and doses of soil amendment (without amendment, zeolite 7.5 t/ha, zeolite 15 t/ha; biochar 7.5 t/ha, and biochar 15 t/ha). It can be concluded that soil amendments application improved the chemical properties of psamment, fresh-dry weight, N-S content, and N-S uptake of basil. Furthermore, biochar and zeolite could increase the effectiveness of fertilization, so the dose of Urea-ZA fertilizer could be reduced until 50%.

to study the effect of nitrogen forms (ammonium nitrate and urea) and sulfur treatments (0, 5, 10 and 15 mM) from two sources (potassium sulphate and calcium sulphate) on garlic yield, chlorophyll, carbohydrates, phenols, nitrate and elements content. Results revealed that ammonium nitrate-fertilized plants had the highest nitrate content in the absence of sulfur treatments. However, plant growth, yield, chlorophyll, phenols, NPK, Ca and S reached the maximum values and nitrate content decreased when plants were sprayed with potassium sulphate at 10 mM. Potassium sulphate was more favorable than calcium sulphate for improving the plant growth, yield and other bulb quality such as phenols and S content. Urea-fertilized plants showed less bulb yield and nitrate content than ammonium nitrate-fertilized plants, but higher than un-fertilized plants. Chlorophyll, nitrogen, phenols and S content were lower and the carbohydrates content was higher in plants grown with un-fertilized than in well fertilized with nitrogen. The results showed that N and S nutrition during the growth and bulb production are strongly coupled. Their interactions are synergistic at suitable form of nitrogen (ammonium nitrate) as well as at optimum rate of potassium sulphate (10 mM). However, excessive level of potassium sulphate (15 mM) seems to be antagonistic. Together, the results indicate that S spraying is required to improve N-use efficiency and thus increasing the bulb yield with high minerals nutrient such S and N content which are very important for S-containing bioactive compounds in garlic.
