Abstract

  A field experiment was conducted at Ghazala farm to study the effect of indol acetic acid  (IAA) and indol butric acid (IBA) on the yield and some biochemical constituents in corn grains. The results of this study can be summarized as following:- All treatments increased the grain yield of corn, but using a mixture of both hormones is more effective than the use of a single one. Spraying IAA or IBA had  an increase on non-soluble  nitrogen fraction, but the soluble nitrogen was decreased. The highest increase of total and insoluble carbohydrates were recorded at 50 and 100 ppm IBA. All treatments decreased the percentage of oil in corn grains  when was the mixture of 50 ppm IAA and IBA. The total free amino acids were slightly decreased by the used IBA treatments, whereas, the second level of IAA and a mixture of 50 ppm IAA. +50  IBA caused an increase of total amino acids in corn grains. Both IAA or IBA decreased the P and K content of corn grains, especially when,  IBA applied.    In conclusion, spraying corn plants with a mixture of (IAA) and (IBA) increase the yield, soluble ,insoluble nitrogen and slightly increase the total contents of amino acids, but decrease total content of carbohydrate, the percentage of oil contents. Also the net result recorded that spraying corn plants with 50, 100 ppm (IAA) increased    yield, total  nitrogen  content, total carbohydrate content, total amino acid content in case of spray[ng by100 ppm ,but decease the  total content of oils,  while in case  spraying by of 50 ,100 ppm ( IBA) will increase yield, nitrogen contents, total carbohydrates, but decrease the total amino, and oil contents. All treatment application decreased (P) and (k) contents.
