Abstract

A pot experiment was conducted in the greenhouse of the National Research Centre at Dokki, Cairo, Egypt. This work designed to investigate the effect of nano-fertilizer and potassium citrate on yield and mineral status of wheat plants Gemmaza 12. The main Data were: Spike length and weight, No of spikes/plant and 1000 grain weight (seed index) decreased with the increase in salt stress. Also spike and weight/plants showed approximately the same response. total weight, plant height and yield and yields traits i.e No of spikes , weight, grain weight/spike, seed index (1000 grain weight), spike weight /plant and grains weight /plant increased by both potassium citrate and nano-fertilizers in comparable with the control plants. While grains of spike increased by potassium citrate more than nano-fertilizer but the differences in spikes length did not reach the level of significant. Under fresh water treatment, yield and traits except spike length increased by both chemical treatments but the increment with nano-fertilizer more than that with potassium citrate but on reverse length of spike decreased by both foliar treatments. The increment in grain of spike with potassium citrate was more than that of nano-fertilizers. In the case of grains/plant the increment seemed to be equal. Both sprayed materials improved yield and most of yield attributes under salinity. N and Mg % increased by salinity but K, Mn and Zn % decreased with the increase in salt concentration in water of irrigation. However, Fe percentage decreased only with the 1st level of salinity, and that N and Mg % increased by salinity but K, Mn and Zn % decreased with the increase in salt concentration in water of irrigation. The interaction effects of either nano or potassium citrate fertilizer and salt stress on grains were significant
