Growth and Yield of Maize by Nitrogen and Potassium Inorganic Fertilizers Application to Fluventic Eutrudepts

Abstract

Maize production requires nutrients so that the soil becomes fertile and makes it easier for plants to grow well. It has been known that potassium nutrient enhances the carbon cycle in plant to maintain the development of plant and so on the yield quantity. This test was carried out from November 2022 to March 2023 on Fluventic Eutrudepts Located in Jatinangor. This test was carried out using a Randomized Block Design (RBD), which consisted of seven combinations of inorganic compound fertilizer nitrogen and potassium (NK) dose treatments. Each treatment was repeated three times. The test results showed that a dose of 1 ¾ NK accompanied by 1 dose of single nitrogen and phosphor (NP) could significantly increase maize yields compared to the control or without the addition of solid inorganic fertilizer NK inorganic fertilizer. The effect of giving solid inorganic fertilizer NK 1 ¾ dose of inorganic fertilizer significantly increase the yield of corn plants compared to the control treatment (without NK).
