Abstract

A field experiment was carried out at Baloza Research Station of the Desert Research Center, North Sinai, Egypt, to study the effect of applying 50, 75 and 100% of the recommended rates of nano-zeolite phosphorus (20.9% P2O5), zeolite phosphorus (8% P2O5), and the ordinary superphosphate fertilizer (15.5% P2O5) to yield components, nutrients content, uptake by straw, seeds of peanut crop (Giza 6 cultivar), and the level of available nutrients in the sandy soil. Zeolite and nano porous-zeolite measuring a dimension of 730.8 and 90.2 nm, respectively, were used in this study. Application of nano-zeolite phosphorus resulted in the highest values of yield components including 1.89, 3.48, 1.46-ton fed-1 and 53.2 % for pod, straw, seeds crop and oil content, respectively. This study came to the conclusion that the well-organized use of fertilizers can be enhanced through using nano sources, so the pollution hazard can be reduced.
