Study the impact of spraying different concentrations of zinc on the vegetative growth characteristics and biological yield components of wheat plant (Triticum aestivum L.) variety Abu Ghraib

Abstract

The trial was focused on the purpose of enhancing growth and yield of wheat crop by spraying zinc solution. studies showed that zinc spray in specific concentration was lowered not plant’s height but an increased harvest index which indicates high conversion rate of assorted photosynthetic products into grains. The remedies, in addition to productivity, reflected a strong improvement in wheat yields, number of spikes per plant and 1000 grain weights. The research is emphasizing that zinc serves a purpose in promoting wheat growth, elevating the grain quality, and increasing the content of the wheat in nutrient value. Besides using zinc for leaves spraying for a desired plant physiological outcome, zinc can also be used in other ways so as to improve soil fertility and overall crop production which in turn will contribute to the sustainability of agricultural systems. The plant height as well as the harvest indices presented highly significant differences between these control and Zinc addition rates i.e. 0.4 tons and 0.8 tons per hectare, decrease wheat plant height which was -4.25% and -7.53% respectively compared to the control treatment. Nevertheless, the harvest index markedly improved in those all trials while the standard treatment remained constant. When the treatment for zinc that use a rate of 0.8 tons for each hectare is sprayed, harvest indices reaches the highest effectiveness than other treatments. Application zinc at the range of 0.4 kg/ha produced a statistically significant wheat yield that was an increase by 55.6% compared to decreased rate which was maximized at the level of 0.8 kg/ha of spraying. The treatment results were unaffected in terms of the number of spikes per plant or the weight of 1000 grains compared to the results when looking at the yield. When compared to individual leaves (foliar application), the observation that the concentration of zinc on the plant increased, in return, affected the wheat plant yield positively on a dry matter, grains and grain count level.
