Growth and Production Response of Five Hybrid Maize Varieties to Application of Different Fertilizer Packages
Respon Pertumbuhan dan Produksi Lima Varietas Jagung Hibrida Terhadap Aplikasi Paket Pemupukan Berbeda
Abstract
This study aims to see the effect or response of five varieties of corn to the package of fertilizer doses observed from the growth and production. The research used a two-factor factorial experimental design in a Randomized Block Design, with 5 hybrid corn varieties as the first factor, namely varieties P21, P22, C9, C7 and Agricon, Urea, ZA, SP-36 and KCl fertilizers. Fertilization Package as the second factor was arranged with a combination of (1) Urea 350 + ZA 100 + SP-36 175 + KCl 75 kg ha-1, (2) Urea 250 + ZA 100 + SP-36 100 + KCl 50 kg ha-1, and (3) Urea 250 + ZA 100 kg ha-1 The results showed that there was an interaction between corn variety C7 and fertilization package 1 (350 urea + 100 ZA + 175 SP-36 + 75 KCl kg ha-1) on the addition of the best number of leaves which was 7,853 strands. Hybrid variety C9 gave the highest yield per hectare of 5.573 tons, and the fertilization package that gave the best results on corn production was fertilization package 3 (250 urea + 100 ZA kg ha-1) with an average grain yield per hectare of 5.07 tons.
