Response of corn plants (Zea mays L.) to application of zeolite coated urea as nitrogen slow release fertilizer

Abstract

This research aims to determine the growth response of corn plants (Zea mays) given zeolite coated urea fertilizer as a nitrogen slow-release fertilizer. This research uses Randomized Group Design (RGD) with 3 repeats. The observation parameters are. Corn plant growth including corn cob weight (grams), corn cob length (cm) and corn kernel weight (grams) which are measured after harvest. The research results showed that there was interaction between zeolite coated urea fertilizer and the corn plant growth results with different results than other treatments namely negative control (only Mono Potassium Phosphate fertilizer) and tending to be better than positive control (urea fertilizer and Mono Potassium Phosphate).
