THE EFFECT OF POTASSIUM SULFATE FERTILIZER ON POTASSIUM AND SULFUR CONTENT IN SOIL AND CORN YIELD (Zea mays L.) IN INCEPTISOL JATINANGOR
Abstract
Sulfur and potassium are two crucial elements that plants need. Sulfur is crucial for boosting the quality and quantity of agricultural harvests, whereas potassium is important for the process of plant growth. The research aimed to determine the effect of applying K2SO4 fertilizer on the K and S content in the soil and corn crop yields on Inceptisol.A Randomized Completely Design was used in the experiment at the Laboratory of Soil Chemistry and Plant Nutrition. Seven different potassium sulfate dose combinations were used, along with one dose of standard NPK, and one dose of control treatment for comparison. Each treatment was carried out three times.The parameters in this experiment were the content of potassium and sulfur also the yield of corn components. The results showed that, in comparison to the control and other treatments, applying one and a quarter-dose of potassium sulfate fertilizer had the greatest outcomes for the soil's potassium and sulfur content as well as corn yield. The maximum weight of corn cobs per hectare in comparison to the control and other treatments was 8,959 kg ha-1.
