The Genotype and Crop Age Effect on Nutritive Value of Corn Forage

Abstract

Background: The Corn crop (Zea mays) was one type of feed crop which is a good source of crude fiber for ruminant. Corn crops had several types of genotypes and each genotype had its advantages in terms of productivity and nutritional content. Methods: The study was conducted from January to May 2018, at the Agricultural Research and Development Research Studio located at Arjasari Village, Arjasari District, Bandung Regency, West Java, in Indonesia. The purpose of this study was to determine the effect of various genotypes and crop ages on crude protein, crude fiber, crude fat, energy and Nitrogen free extract of Corn forage. This research was designed with an experimental method using a Completely Randomized Design. The treatments in this study were the genotype of Corn crop and the crop age.Result: The results of the statistical analysis showed that the interaction of genotype and age gave different results on Nitrogen free extract and crude fiber at 5% significant level test. Genotype and age interaction did not give different results on Energy, Crude Fat and Crude Protein at 5% significant level test.
