RESPONSES OF FENUGREEK PLANT TO PHOSPHORUS AND POTASSIUM FERTILIZATION

The present work was conducted during two seasons1990/1991 , 1991/1992 . At the farm of Medicinal and Aromatic Plant Section in Dokki 'and Sed Research Stations. The aim of this research was to study the effect of three levels of calcium supper phosphate ( 15.5% P₂0₅) (100,15 and 200kg/fd.) and two levels of potassium sulphate (48% 1(₂0₅)_, (150 and 100 kg/fd.) on the vegetative growth, yield and fixed oil of fenugreek plant. Generally data cleared that plant treated with 200 kg. calcium super phosphate and 100kg potassium sulphate gave the highest values of plant height, number of pods, fresh and dry weights of plant in both locations. In Dokki location the treatment with 200 kg calcium super phos­phate and 50kg potassium sulphate gave the highest results in branch number, seed yield, oil percentage and oil yield, but in Seds location the highest values were obtained by using 200 kg calcium super phosphate, 1004 potassium sulphate.
