Abstract

The research objective was to examine the utilization of bio gas slurry and bio gasslurry enriched with goat’s urine fermented on Indigofera zollingeriana. The experiment wasconducted at the Goat Farm Research Station Sei Putih, Galang, North Sumatera, from Marchuntil August 2015 using 24 plants of Indigofera zollingeriana. Design experiment was usedsplit plot design where main plots were different dosages of fertilizer, i.e. R1 (75), R2 (150)and R3 (225) ml/plot with four replications. The sub plots were types of fertilizer, i.e. slurry(P1) and slurry and goat’s urine fermented (P2). The research parameters were plant height,leaf production and chemical compositions (rough fat, NDF and ADF).The results showed that dosage fertilizer application of gas slurry and bio gas slurry enrichedwith goat urine fermented was not significantly different to plant height, leaf production andcrude lipid. There was no significantly different on plant height between types of fertilizer, i.e.bio gas slurry and bio gas slurry enriched with goat’s urine fermented. There weresignificantly different (P<0,05) between types of fertilizer, i.e. bio gas slurry and bio gas slurryenriched with goat’s urine fermented on leaf production and chemical compositions. It isconclude that utilization of bio gas slurry enriched with goat’s urine fermented increaseproductivity of Indigofera zolingeriana

Highlights

Indigofera zollingeriana is a leguminous plant, trees for animal fodder which gives better nutrients especially protein, phosphor, and Calcium (Tarigan and Ginting, 2011)
Indigo is categorized as a tolerant plant toward severe drought (Herdiawan, 2013)
Indigofera is commonly used as cover crops in plantations area like coffee, as green fertilizer, dyeing cloth, and herbal medicine (Herdiawan and Krisnan, 2014)

Summary

Introduction

Indigofera zollingeriana is a leguminous plant, trees for animal fodder which gives better nutrients especially protein, phosphor, and Calcium (Tarigan and Ginting, 2011). Indigofera can be used as basal fed goats in replacement of grass This thing benefits farmer especially in extreme climate followed by flood phenomenon cause farmer getting trouble to cut the grass. Indigos research can be used by farmer these days, for helping a good animal growth needed cheap fed resources, easy to get and have nutrient content especially good protein. Animal such as milking goat, i.e. Peranakan Etawah needs such fed. Indonesia is very susceptible with the climate change impact like flood and drought that leads agriculture land become parched, cultivating season happened and outbreak from OPT (Plant Pest Organisms). The government launches Regional Action Plan (RAD) Greenhouse Gases and RAD GRK in North Sumatera decide a policy for doing livestock feces cultivation turned to gas bio as well as compost (Ginting, 2012)
