Effect of adding Humic acid and Foliar Application with Nano NPK on some growth and yield characteristics of Apple trees
This study was carried out in one of the private orchards, which is 20 km away from Kirkuk governorate in the Altun Kobri area and affiliated to Dibs district for the spring season 2021, for the purpose of studying the effect of fertilizing with humic acid at three levels (40-20-0) g. tree-1.

| description | This study was carried out in one of the private orchards, which is 20 km away from Kirkuk governorate in the Altun Kobri area and affiliated to Dibs district for the spring season 2021, for the purpose of studying the effect of fertilizing with humic acid at three levels (40-20-0) g. tree-1. With four levels of nano NPK (3.5-2.5-1.5-0) mg. L-1 in some traits, growth and yield of apple trees of the local cultivar Ibrahimi. The experiment was designed according to a randomized complete block design (RCBD) a global experiment that included three levels of humic acid and four concentrations of NPK nano compound fertilizer And with three repetitions and one tree for each experimental unit, so the number of observations becomes 36, the number of transactions in each sector (12) treatments, and the number of trees involved in the experiment is 36 trees.The transactions were randomly distributed to the experimental units. Where it was noticed that when adding 40 g.l-1 of humic acid led to a significant increase in the following traits (fruit weight, fruit size, vitamin C). The following characteristics (fruit weight, fruit size, total soluble solids percentage, vitamin C). Among the results of the interaction between 40 g. tree-1 and 3500 mg.L-1 of nano-NPK, it was superior in the following characteristics (fruit weight, fruit size , percentage of total soluble solids, vitamin C). |
