THE EFFECT OF PHOSPHORUS APPLICATIONS ON CHANGES IN THE SOIL CONTENT OF P AND YIELDS OF BARLEY BIOMASS

Abstract Balanced nutrition and fertilisation is essential for soil fertility and a prerequisite for achieving adequate yields and quality of production. (65 -90 -116 mg/kg). Dry matter yields of the aboveground biomass were the lowest in the control treatment not fertilised with P (63.3 g per pot) and increased significantly with the P rate applied (66.7 -68.6 -70.7 g per pot)
