  2. 30/ 11/ 2016 INTRODUCTION  Green house fodder (GHF) or hydroponic fodder is a vertical planting system with hydroponic systems in greenhouses that produce high-quality forage  Used grain, such as: corn, wheat, barley, sorghum, act.  Aspect influence on yield and quality of GHF are:  nutrient solution, seed density, temp, light, watering system, etc.  Bioslurry is effluent that produced from biogas digester containing rich nutrient for plant. O BJECTIVES  T o know the effect of bioslurry from biogas digester as nutrient solution and seed density on production and quality of corn hydroponic fodder. 2

  3. 30/ 11/ 2016 METHODOLOGY  Location:  University Farm’s Green House, Darmaga, Bogor  Green House Fodder (GHF) Production:  Corn GHF was produced in addition different nutrient solutions and seed density.  The nutrient solutions:  0% bioslurry + 100% commercial nutrient solution  25% bioslurry + 75% commercial nutrient solution  50% bioslurry + 50% commercial nutrient solution  Seed density:  350 g/ tray, 450 g/ tray and 500 g/ tray  Corn were grown for 8 days GHF P RODUCTION STEP ACTIVITIES 1. Seed selection 2. Soaking in water for 24 hours 3. Washing with clean water Placed in trays, spraying with 4. nutrient solution for 7-8 times, or used aoutomatic watering system 5. Harvesting after 8 days 3

  4. 30/ 11/ 2016 METHODOLOGY  Parameters:  Fresh and DM biomass yield, plant growth, nutrient content (Ash, CP , CL, CF , NFE), DM in vitro digestibility, total VFA and NH 3 concentration  Experimental design:  A factorial (3 x 3) design  Data analyses using ANOVA GHF P RODUCTION 4
