摘要

Two successive experiments were carried out during 2009 and 2010 summer seasons at Desert ResearchCenter farm, Ras Sudr, South Sinai. The aim of the experiments was to investigate the effect of mineral acidsand growth amendments on growth, yield and its components and mineral composition of eggplant. Fourtreatments of mineral acids were applied through drip irrigation system which were, control, 50 L + 10 L, 75 L+ 15 L and 100 L + 20 L of HNO3 + H3P2O5, respectively. The investigated amendments were control, 4 kghumic acid, 75 kg magnetite and 1 L amino acids / fed. in addition to a mixture of previous treatments. Humicacid and magnetite were applied as soil addition while amino acids were foliar sprayed. Split plot design wasused where main plots was assigned for mineral acids and sub plots for amendments. Results showed thatmineral acids increased plant growth and yield and its components. The effect was increased as mineral acidsquantity was increased. Mineral acids, also, increased potassium and phosphorus content of fruits while nitratecontent was decreased. The highest values of P and K were obtained, in general, with 75 L HNO3 + 15 LH3P2O5 and the lowest values of NO3 in fruits were obtained with 100L + 20L and 75 L + 15 L of HNO3 +H3P2O5, respectively. As for growth amendments, results indicated that its application increased growth andyield and its components; the highest values were obtained with mixture application treatment (humic acid +magnetite + amino acids). Results also indicated that application either of magnetite or humic acids increased Pand K and decreased NO3. Amino acids application increased NO3 and P but decreased K content. As for theinteraction between mineral acids and growth amendments, the best growth and highest yield and itscomponents were obtained with the highest quantity of mineral acids (100L HNO3+ 20L H3P2O5 /fed.)combined with the mixture of amendments (humic acid + magnetite + amino acids). Also, phosphorus andpotassium content was increased; the highest values were obtained with amendments mixture combined withany quantity of mineral acids. On the other hand, nitrate content was decreased and the lowest values wereobtained with any mineral acids quantity combined with the application of humic acids or magnetite.
