| Abstract | ||||
| Two field experiments were carried out the two successive summer seasons of 2002 and 2003 to investigate the performance of Jew’s mallow plant (Corchorus olitorus L.) cv. Balady in relation to some different nitrogen sources (ammonium sulphate, urea, calcium nitrate and ammonium nitrate) and potassium sources (potassium chloride and potassium sulphate) on the vegetative growth characters, foliage yield and its some chemical properties. The important results could be summarized as follows: Fertilization with ammonium nitrate (33.5% N) gave the best values of vegetative growth characters expressed as plant length, leaves number/plant , leaves area/plant, fresh and dry weights of leaves weights/plant and whole plant as well as total foliage yield and N, P. and K contents in leaves tissues compared with other nitrogen sources. On the other hand, addition of ammonium sulphate (20.6% N) gave the lowest values of the above mentioned plant growth characters. Addition of potassium sulphate enhanced vegetative growth characters as well as total foliage yield compared to potassium chloride. The vigor vegetative plant growth and the heaviest total foliage yield were associated with application of ammonium nitrate (33.5% N) and potassium sulphate (48%K2O). | ||||
