Abstract The present investigation aims to study the chemical treatment of water hyacinth (Nile rose) to produce different organic fertilizers. The effect of the prepared organic fertilizers on the growth, quality and chemical composition of corn crops and their effects on some soil properties at harvest were evaluated in field experiment at Ismailia Research Station, Ismailia Governorate, Egypt. Organic fertilizers were prepared by acid hydrolysis of water hyacinth to obtain water hyacinth leaf fertilizers (WHLF). A germination experiment was done on a laboratory scale to determine the best treatments for application in field experiment. The best treatments were: 0.04% WHLF + NPK; 0.06% WHLF + NPK; 0.08% WHLF + NPK; 0.02% WHLF +NK; 0.04% WHLF +NK; 0.06% WHLF +NK; 0.06% WHLF +NPK+M and 0.06% WHLF +NPK+M. The field experiment was duplicated in two seasons of 2013 and 2014. The effects of the different fertilizers on growth quality parameters of corn (Zea mays) and also their effects on some soil properties were determined. The data showed that all fertilizer treatments exceeded that of unfertilized control in plant height (cm).The statistical analysis revealed that the treatment type, cultivation duration and their interaction had significant effect on corn height. The number of cobs during the first and second cultivation seasons did not show any significant differences for all treatments whereas the weight of the cobs (g) was significantly higher in all fertilized groups compared to the control (unfertilized treatment) |
