Effect Of Nano-Fertilization On Growth And Yield Of Three Varieties Of Wheat Bread (Triticum Aestivum L.)

The field experiment was carried out in one of the Agricultural fields during the 2018/2019 agricultural season of Al-Rumaitha district 25 km north of Al-Muthanna Governorate, to study the effect of spraying with a mixture of humic and nanoparticle herbal extract on growth and yield of wheat. The experiment was applied according to the arrangement of the split plot design, as the humic mixture and the nanoparticle extract were placed in the main plot with three concentrations (zero, 2, 4) g.liter(-1) and symbolized by the symbol (B-0, B-1, B-2) on the sequence, while the Varieties of wheat were placed in the sub plot, which are (research 22, Ebaa 99, Iraq) symbolized by the symbol (V-1, V-2, V-3) on the sequence and using the design of the complete random sectors (RCBD) with three replicates. Soil servicing operations were performed by plowing, smoothing and leveling and then dividing the field according to design used then seeds were planted on (15.11.2018) [Al-Asil et al. (2018)] with a seed quantity of 120 kg.ha(-1) [Al-Muaini and Mohsen (2016)] and cultivation was done on lines along of 2 m and the distance between each line and another is 20 cm and the experimental unit is a board (2 x 2 = 4 m(2)). Nitrogen fertilization was carried out in the form of urea fertilizer 46% N according to fertilizer recommendation in amount of 120 kg N. ha(-1) by two batches the first one after 15 days of cultivation and the second after 45 days from the first batch, while phosphorus was added in the amount of 80 kg.ha(-1) P2O5 in the form of super fertilizer Triple phosphate (46% P) [Al-Abedi (2011)]. The following results were obtained at plant height, V-3 scored 82.04 cm, B-2 scored 82.87 cm and in chlorophyll gave B-2, 36.95 and spike length V-3, scored 13.84 cm, number of spikes outperformed B-2, which gave 539.40 spike.m(2), the number of grains in the spike exceeded V-3 and scored 64.80 grains.spike(-1), the grain yield exceeded V-3 and scored 6697 kg.ha(-1) and the biological yield V-3 gave 13921 kg.ha(-1) and B-2 13690 kg.ha(-1).
