مطالعه تاثیر کاربرد کود فسفات آمونیوم، باکتری های تسهیل کننده جذب فسفر و اسید هیومیک بر عملکرد ذرت سینگل کراس 704

In order to investigate the application of ammonium phosphate fertilizers, phosphorous solubilizing
bacteria and humic acid on morphological characteristics of SC 704 corn this study was conduct in
1390 at the experimental farm of College of Agriculture and Natural Resources, Tehran University,
Karaj, in a randomized complete block design with three replications. In this experiment, grain yield,
plant height and number of leaves were studied. The results showed that the treated plants whit 100%
phosphorus and humic acid and bacteria maximum plant height were combined. According to the
chart, the highest grain yield of 100 % phosphorus, and the combined interaction of Pseudomonas
6785 kg per hectare. Increasing phosphorus intake, an increasing trend was observed for plant height.
Most treatments use 100% of the dry matter yield and phosphorus fertilizers combined humic acid
and Pseudomonas belonged.
