Effect of hydroponic crop set system powered by various types of energy on the growth of green oak lettuce

A major problem in the hydroponic crop set system is the power supply. Generally, it runs from conventional electric energy and it should continue to run all the time. This research attempted to investigate the potential and efficiency of the hydroponic crop set system powered by various types of energy. The design and construction was proposed to response the needs to reduce energy consumption and finding the cheap renewable sources of energy. The experiments were laid out in completely randomized design (CRD). There are three types of energy supply for hydroponic crop set system: 1) conventional electrical energy; 2) solar energy with battery; 3) solar energy without battery. The overall sizes of a hydroponic crop set system are 1 m width and 4 m length. The growth of green oak lettuce on hydroponic crop set system which are powered by various types of energy supply was tested for potential and efficiency by sowing the seed of green oak lettuce for 7 days and then transferring the stems of green oak to a hydroponic crop set system and observe the growth of green oak for 43 days. Green oak was collected to determine the canopy width, root length, fresh weight and dry weight of each stem. It was found that the highest canopy widths of green oak were achieved from hydroponic crop set system powered by solar energy with battery. The highest root lengths and stem fresh weight of green oak were achieved from hydroponic crop set system powered by conventional electrical energy. The highest root fresh weights of green oak were achieved from hydroponic crop set system powered by solar energy with battery. The highest stem dry weights of green oak were achieved from hydroponic crop set system powered by conventional electrical energy. The highest root dry weights of green oak were achieved from hydroponic crop set system powered by solar energy with battery.
