Effect of Spraying Stages of Micro-Nano Elements on some Productive and Economical Traits of Wheat Cultivars (Triticum aestivum L.)

Abstract The aim of the research is to study effect stages spraying nano-microelements on some yield characteristics and economic feasibility wheat varieties. Soil with a mixture clay texture using split plank design random complete sectors (R.C.B.D) cultivars coded (Abu Ragheef V1, Baghdad V2, Babil V3, Aba 99 V4) occupied main panels, while (tillering stage S1, booting S2, flowering S3) secondary panels. results showed differences between in studied traits, as father variety was significantly superior number spikes grains per spike amounted 410.7 m 2 82.7 -1 , respectively, characteristic grain 7.354 tons h biological 24.006 total revenue 8,629,944 dinars net profit 6,430,044 Abu excelled weight 1000 grains, amounting 44.19 gm. As for stages, Al-booting gave highest average spikes, which 369.3 Al-Booting 7,406 22,481 t 8,448,561 . overlap micro-nano elements cultivars, combination (Aba 99×S2) 7.788
