| Abstract | ||
| A factorial experiment was carried out in the Directorate of Sarchnar Nursery in Sulaymani / Kurdistan Region-Iraq, using a randomized complete block design (RCBD) with three replications to study the effect of using root stimulator (Rootex) at three levels were (0 )mgL-1, (670)mgL-1 and (1.34) gmL-1 and foliar application with organic nutrients (Siapton 10L) with three concentration on 1st October 2021 as well, which were (0, 1and 2) mlL-1 and there interactions on Cupressus arizonika’s seedlings growth. The data were analyzed using XLSTAT software, and averages were compared according to Duncan Multiple Range. The results showed the superiority of Rootex treatment at the level 1.34 gmL-1 on the studies characteristics (plant height, percentage of N, P, K in the leaves, chlorophyll content in the leaves, Zink and Iron concentration in the leaves, root length, shoot fresh and dry weight, shoot dry matter and root fresh and dry weight). Treating seedlings’ foliar with (Siapton 10L) at the concentration 2mlL-1 showed the superiority in the studies characteristics (plant height, percentage of N, P, and K in leaves, chlorophyll content in the leaves, Zink and Iron concentration in the leaves, root length, shoot fresh and dry weight, shoot dry matter, root fresh and dry weight and root dry matter). The dual interaction of 1.34 gmL-1 of Rootex with 2mlL-1 (Siapton 10L) showed the superiority in the studies characteristics of (plant height, percentage of N, P, and K in leaves, chlorophyll content in the leaves, Zink and Iron’s concentration in leaves, root length, shoot fresh and dry weight, and root fresh and dry weight. | ||
