Abstract
Murdannia bracteata is one of potential forages for ruminant that has not been studied yet. This forage contents high mineral and it can be as fungtional feed. The aim of this study was to evaluate the growth and productivity, chlorophyll and minerals content of Murdannia bracteata caused by magnesium foliar application. The experiment was arranged in randomized complete design with five treatments and 4 replications. The application of magnesium level was arranged into: 0 ppm, 2000 ppm, 4000 ppm, 8000 ppm, and 12000 ppm. The study was conducted in a greenhouse, field laboratory of Agrostology, Faculty of Animal Science , Bogor Agricultural University . The result showed that growth, productivity, and chlorophyll content were not significantly (P>0.05) affected by increasing magnesium level. Increasing magnesium dossage resulted in decreasing calsium, potassium, and zink content (P 0,05). In conclusion, increasing magnesium dossage up to 12000 ppm did not significantly affect growth, productivity, and chlorophyll content. However, increasing magnesium level decreased calsium, potassium, and zink content.
Highlights
Murdannia bracteata is one of forage has not been widely studied
Administration of organic fertilizer by 10 ton ha-1 and 37% shading affect the height of level of calcium (Ca), magnesium (Mg), calium (K), and zink (Zn)
Administration of foliar fertilizer was carried out to determine capability of that M. bacterata in increasing magnesium content without disturbing the growth, productivity, and its quality planted on lasotol dramaga soil
Summary
Murdannia bracteata is one of forage has not been widely studied. This potential forage as ruminant’s functional feed included into class Commelinales, family Commelinanceae, genus Murdannia and species M. bracteata Administration of organic fertilizer by 10 ton ha-1 and 37% shading affect the height of level of calcium (Ca), magnesium (Mg), calium (K), and zink (Zn) Content of those Ca, Mg, K, and Zn is. 16847 ppm, 4566 ppm, 29323 ppm, dan 44 ppm, respectively Those minerals content were higher compared to other forages such as Brachiaria humidicola and Indigofera sp. Magnesium content in the darmaga latosol soil was only 0.06% (Utami 2015) That liquid fertilizer entered the leaves by penetration process to cuticle tissue through stomata pathway (Aghtape et al 2011). Administration of foliar fertilizer was carried out to determine capability of that M. bacterata in increasing magnesium content without disturbing the growth, productivity, and its quality planted on lasotol dramaga soil
