A locally fabricated hydroponic unit, with shade net walls, metal sheet as roof and having manual water sprinkling system was utilised. A 2 x 3 factorial design in five replicates was adopted to assess the influence of soaking (8 or 12 hours) and germination time (24 or 30 or 36 hours) of maize seeds (Zea mays L.) on biomass yield of hydroponic fodder maize. Though, no significant variation (P < 0.05) was observed on the biomass yield of hydroponic fodder maize irrespective of the soaking and germination times numerically higher biomass yield at 12 hours of soaking and 24 hours of germination was observed. A study to determine the influence of seed rate (100, 150, 200 250 and 300 g / sq.ft) on biomass yield of hydroponic fodder on 9th day of growth revealed, highest biomass yield (4.50 ± 0.57kg/ kg of seed) at a seed rate of 250 (g/sq.ft).
