Abstract

Air temperature and lighting time are considered main elements in sprouting and growth biosystems environment. High and low temperature stresses have dangerous effects on quality and quantity of plants. Long and short time of lighting cause disturbance in photosynthesis processes. Importing automatic systems for controlling the environmental elements is very expensive. To determine the suitable conditions inside the biosystem, three levels of temperature, three levels of daily lighting time, and two varieties of barley were studied through complete randomized trial. Giza 126 and Giza 128 varieties were studied as models for six and two-row barley. Electric control system for adjusting air temperature and managing lighting time inside sprouted chamber was locally designed and fabricated. Water use efficiency, percentages of dry matter, ash, crude protein, ether extract, crude fiber and nitrogen free extract were used as criteria of sprouted production quality. Statistically, fixing the sprouted green barley chamber on 20oC and 12h per day is considered the best condition for the six and two-row barley under the soilless hydroponics conditions. To evaluate the quality of the produced green fodder, growth experiment on four groups of lambs was carried out. The results showed that using rations containing sprouted green barley gave higher values of final body weight, total gain and average daily gain.
