Farklı Işık Şiddeti ve Karbondioksit Dozu Uygulamalarının Hidroponik Arpa (Hordeum vulgare L. conv. distichon) Çimi Üzerine Etkileri

Abstract

This research was conducted to determine the effects of different light intensity and CO2 dose treatments on hydroponic barley (Hordeum vulgare L. conv. distichon) grass. In the study were investigated the effects of different light intensity and carbon dioxide dose treatments on green fodder yield and rate, dry matter rate and losses, crude protein gains, plant height, and root lenght, crude nutrient contents, cell wall components, metabolic energy values and mineral elements content. According to the research results, in the different light intensity treatments, the highest green forage yield, crude protein gain, plant height, crude oil, NDF, ADF, metabolic energy and Fe contents, and the lowest dry matter losses were obtained from I2 and I3 treatments, and the highest dry matter rates and losses, crude fiber and P contents were obtained from I1 treatment. In the different carbon dioxide dose treatments, the highest green forage yield, crude protein gain, crude nutrient, metabolic energy and N contents, with the lowest dry matter losses were obtained from D1, D2 and D3 treatments. The highest crude fiber, ADF and Ca values were obtained from D1 and D2 treatments. The highest NDF, ADL, P, K, Mg, Fe, Cu, Mn, Zn, and Na values were obtained from D2 treatment. I2 and I3 light intensity and D1, D2 and D3 carbon dioxide dose treatments can be recommendable in order to produce hydroponic green barley fodder in which having high green fodder yield, crude protein gain and low dry matter losses. When production cost is taken into consideration I2 light intensity and D1 carbon dioxide dose treatments become more important.
