Foliar application effect of Some Bio, Nano Fertilizers and Bio Stimulants on Some Growth Traits, Yield and Active Substances of Wheat

Abstract

In one of the private nurseries in Al-Qadisiyah Governorate, specifically in the Al-Shafeieyah district, Iraq, a field study was conducted to test the impact of selected bio, nano fertilizers and biostimulants on the agronomic traits and quality of grain. The design of the experiment was according to a Randomized Complete Blocks Design with four replications in a simple one-way experiment. The experiment has involved  foliar application of eight treatments namely distilled water as a control treatment, Zn+B+N Nano-fertilizer, Nano amino acids, K+Fe+Zn+Mn Nano- fertilizer, Nano- NPK+ μN, Nano- specific liquid fertilizer, Fertigrain bio-stimulants and foliar application of EM liquid biofertilizer. Using the least significant difference to measure the difference between treatments at 0.05 probability level. Quality and quantity characteristics of some agronomic traits were measured. Results indicated that the EM gave the highest biological and grain yield were (30.60, 10.50) Meg ha^-1, respectively, and the highest % of oleic acid 2.93%. The biostimulants were characterized by obtaining  highest harvest index and agronomic efficiency Which amounted  (41.19%  ,2696), respectively, and did not differ significantly from EM in obtaining the highest grain yield and oleic acid percentage. The highest Linoleic acid percentage was 2.84% obtained by using Nano-specific liquid. The highest Palmitic acid percentage was obtained (5.07%, 5.23%), respectively,  when using Nano amino acids and Nano- NPK+ μN, and they did not differ significantly from each other. Most of the investigated treatments had no effect  on the percentage of stearic acid, while the effect of biostimulants and EM was negative.
