Effect of foliar application of different sources of nano-fertilizers on growth and yield of wheat

A field experiment was carried out at the extension farm in Al-Shafeieyah to study the effect of foliar application of different sources of nano-fertilizers on growth and yield of wheat. The experiment included di spray application of N, P and K Nano-fertilizer (N+P), (N+K), (P+K) and tri (N+P+K), Super Micro Plus SMP nano-fertilizer, Traditional fertilizer (NPK+TE) (AGRIMEL) and without application as control for comparison with three replicates in a simple one-way experience using RCBD design. A number of growth criteria in plant and yield (quality and quantity) parameters were recorded. Results indicated that significant response was spraying of SMP nano-fertilizer followed by the spraying combined of tri (N+P+K), di (N+P), (N+K) and (P+K) nano-fertilizer compared to control and traditional (NPK+TE) fertilizer treatments respectively in all growth and yield parameters of wheat with an increment of the spray foliar (SMP) of 87.77cm, 12.22cm, 58.22 spad, 3.17%, 0.66% and 2.88% for plant height, length of spike, total chlorophyll, concentration of N, P and K respectively compared to control treatment. The same treatment had grain yield and protein % of 5.996 Mg ha(-1) and 13.69 % compared to the treatment of control and traditional fertilizer, which amounted to (4.060 Mg ha(-1) and 11.94%) and (5.198 Mg ha(-1) and 11.94%) respectively. Harvest index were in the range (from 35.27 to 44.96%) for control and nano SMP fertilizer treatment respectively. The highest fertilizer productivity was achieved when spraying treatments of nano SMP and tri nano mixture of (N+P+K) fertilizers (1936.0 and 1581.0 kg kg(-1)) compared to traditional fertilizer (569.0 kg kg(-1)).
