THE USE OF NUTRIENT SOLUTIONS IN THE CULTIVATION OF HYDROPONIC GREENS FROM NAKED BARLEY

The article presents research materials on the use of nutrient solutions in the cultivation of hydroponic greens from naked barley with the study of their effect on the growth of green mass. It was found that nutrient solution No. 2 had the greatest positive effect on plant growth parameters in relation to control: on the eighth – 20.1 mm (P > 0.999), on the ninth – 24.9 mm (P > 0.999) and on the tenth day – 27.2 mm (P > 0.999), and in comparison with plants grown with the use of solution No. 1: on the third day – 2.4 mm (P > 0.95), the fourth – 3.8 mm (P > 0.95) and the tenth day – 8.9 mm (P > 0.95).
