Effect of different nutrient solutions on the biomass yield and nutritive value of low cost hydroponic fodder maize

Abstract

The effect of different nutrient solutions on hydroponic maize fodder growth in a low cost unit was studied. The different nutrient solutions were water, 2.5% biogas slurry, 10% diluted cow urine, 0.1% urea and 10% vermiwash solution. The growth parameter for fodder maize after eight days of sprouting was recorded and the fodder was analysed for its proximate principles. The biomass yield of hydroponic fodder maize was higher with water as a nutrient solution 4.55±0.08 kg/kg of seed. The biomass yield in 0.1% urea and 10% diluted cow urine was significantly lower compared to other treatments. Highest crude protein in maize fodder produced was observed when 0.1% urea was nutrient solution. The beta carotene content of hydroponic fodder maize was higher by 47% compared to that of maize seed.
