The word hydroponics has been derived from the Greek word, “Hydros” meaning ‘water’ and “Ponic” meaning ‘working’. Hydroponics is a technique in which growing of plants/crops in water without any soil, generally in controlled conditions/environment. Water and plant nutrients are essential for plant growth which is incorporated.
For the production of hydroponics fodder, seeds are soaked in normal water for 4-24 hours, depending upon the type of seeds followed by draining and placing it in the individual greenhouse trays for growing inside the greenhouse. For maize, 4 hours soaking in normal water is sufficient. The seed rate (quantity of seeds loaded per unit surface area) also affects the yield of the hydroponics fodder, which varies with the type of seeds. Hydroponics maize fodder can be well produced with seed rate of 6.4-7.6 kg/m2 [8]. If seed density is high, there is more chance of microbial contamination in the root mat, which affects the growth of the fodder. The starting of germination and visibility of roots varies with the type of seeds. In case of maize and cowpea seeds, germination start on about 2nd and 1st day and the roots were clearly visible from 3rd and 2nd day onwards, respectively. Maintenance of clean and hygiene is very much important in the production of hydroponics fodder as greenhouse is highly susceptible to microbial contamination, particularly of mould growth due to high humidity. Inside the greenhouse, generally the grains are allowed to sprout for seven days and on day eight, these are fed to the dairy animals.
