Effect of Nano Phosphorus Fertilizer Levels and Seed Rates on Barley Growth under Different Tillage Equipment

The major benefits of using tillage technology to agriculture are mainly in soil management and fertilizer application. These can help attack major problems such as soil degradation and increase agricultural productivity. The effect both of nutrients and of the quantity of seed have a major effect on the barley growth and the yield. Nanofertilizers can improve the uptake of nutrients and crop performance.

A field experiment was conducted in Al-Qurna District aimed at determining the growth characteristics and yield of barley. Two different tillage systems (Chisel and Moldboard plow) and quantities of seed (40, 60 and 80 Kg/ha) (Sr1, Sr2 and Sr3) were compared under the influence of three levels of the nano-phosphorus fertilizer (0, 1.25 and 2.5 ml/litter) (Nf1, Nf2 and Nf3).

The chisel plow outperformed the moldboard plow in terms of flag leaf area, number of spikes per square meter and grain yield. The moldboard plow outperformed in terms of plant height and biological yield. SR2 achieved the highest average number of spikes per square meter, grain yield and biological yield. As for nano-phosphorus fertilizer levels, the Nf3 outperformed in terms of plant height, flag leaf area, number of spikes per square meter, grain yield and biological yield.
