EFFECT OF SPRAYING WITH A NUTRIENT SOLUTION AND ADDING COMPOST ON SOME INDICATORS OF GROWTH AND YIELD OF WHEAT TRITICUM AESTIVUM L.

A field experiment was conducted to grow the wheat crop, Triticum aestivum L., in one of the fields located in the Abu Gharak district of Babylon province, in the Sayed Ismail region, at the coordinates (44.3754175, 32.5268050), during the season 2021-2022.The effect of spraying with a nutrient solution (which contains a mixture of micronutrients) and adding compost on some indicators of growth and yield of wheat in a mixed soil, where the experiment included two factors and symbol it respectivelyS0, S1, S2.The second factor is the ground addition of co mpost fertilizer at three levels 0, 5 and 10 tons H-1 andwhich is symblois by C0, C1, C2, the experiment was implemented as a factorial experiment according to the randomized complete block design (R.C.B.D), at maturity the plant height, chlorophyll index and the number of branches were measured and the flag leaf area , and at the time of harvest, the biological yield and grain yield were measured.The results of the study indicated that there was a significant effect of the S2C2 bi-interaction treatment in all study indicators represented by vegetative growth traits and yield traits, as it was significantly excelled and it gave the highest values of the vegetative growth traits represented by plant height, chlorophyll index, flag leaf area and number of branching, which values were 112.57 cm, 55.73 spad unit, 54.97 cm2, and 8, respectively. It also excelled significantly and gave the highest values of yield traits represented by grain yield and biological yield, which were 5.258 tons ha-1 and 15.49 tons ha-1, respectively.
