Effect of adding perlite and nitrogen level on the growth and yield of wheat (Triticm aestivum L.)

This study was conducted at Al-Majd area in Al-Muthanna Governorate (Away from the city center about 5 km to the north), to study the effect of perlite and N level on growth and yield of wheat (Triticum eastvum L.). A factorial field experiment, according to a Randomized Complete Block Design (RCBD) with three replicates. The experiment included two factors, the first one is the addition of perlite with three levels (0, 1.5 and 3)% symbolized by B0, B1 and B2 respectively, while the second factor is N at five levels (0, 50, 100, 150 and 200) kg N ha-1 has the symbol N0, N1, N2, N3 and N4 respectively. The seeds of wheat (Bohooth 22 cultivar) were sown on 11/11/2021. The results indicated the significant effect of adding perlite at a level of 3% by volume to the soil in increasing plant growth traits, including plant height, chlorophyll, biological yield, grain yield, N and P concentration in the plant. The effect of adding N fertilizer to the soil at a level of 200 kg N ha-1 in improving plant growth characteristics, including plant height, chlorophyll and K concentration in the plant, while there was no significant difference with the level of 150 kg N ha-1 for each of the N concentration in the plant and t The biological yield and grain yield.
