The College of Agriculture discussed a master's thesis on a comparative study of the effect of traditional and nano phosphorus fertilizer on the growth and yield of white corn varieties (Sorghum bicolor L), by the student Nisreen Sherzad Khazal, under the supervision of Assistant Professor Dr. Ali Hussein Rahim.
The study aimed to compare the effect of nano phosphorus fertilizer with the traditional one through its effect on the growth and yield of the white corn crop and to know the extent of the response of several varieties of white corn to nano phosphorus in order to determine the best level of nano phosphorus with the best suitable variety of white corn crop for the supporting environmental conditions in the study area.
The study concluded that using the full fertilizer recommendation and half of the fertilizer recommendation for nano phosphorus led to improving most of the growth characteristics, yield and its components compared to traditional phosphorus fertilizer. The results of the study also proved that there was a high response to the growth characteristics, yield and its components for nano phosphorus fertilizer compared to traditional phosphorus fertilizer, and that the full nano fertilizer recommendation of 10 kg significantly improved most of the growth and yield characteristics studied, and the performance of the varieties showed a highly significant effect in all the studied characteristics, and the Giza and Ji varieties outperformed in most of the characteristics.
