Pengaruh Pemberian Jenis Pupuk terhadap Pertumbuhan Vegetatif Tanaman Jagung (Zea mays L.) Hibrida

Abstract

One of the main commodities that Indonesia strategically uses to support its economy and growth is maize. This commodity is promising as a food alternative to rice, which is a valuable commodity with a high market value and is often used as the main raw material for animal feed. Plants that lack N, P, and K will experience nutrient deficits in corn plants, resulting in suboptimal growth characterized by stunting and even death. When the needs of N, P, and K are met, plants will develop optimally. The research was conducted from December 2022 to January 2023 in the Greenhouse of Seed Production Engineering of Jember State Polytechnic, this research used a non-factorial Randomized Group Design (RGD) design with one factor repeated 3 times. If there is a significant difference between treatments, further test will be conducted using DMRT (Duncan Multiple Range Test). The results showed that the treatment of N, P and K fertilizer deficiency did not experience a significant effect or not significantly different from the vegetative growth of age (30 DAP) in hybrid corn plants.
