Abstract
A pot experiment was carried out in a plastic house during the two successive seasons of 2013/2014 and 2014/2015 at the Ornamental farm of the Horticulture Department, Faculty of Agriculture, Ain shams University, Shoubra El-Kheima, Kaliobia Governerate. This research study was carried out to investigate the effect of amino acids (as a commercial compound Amino Zeid) applied at the rate of 250, 500 and 1000 ppm using two methods of application as soil drench and foliar spray in addition to two controls,i.e. tap water without amino acids for each application method. The obtained results showed that using amino acids in general increased plant height, number of leaves/plant, number of branches/plant, stem diameter, vegetative fresh and dry weight in the two studied seasons. Amino acids at 1000 ppm as soil drench gave the highest results in the above mentioned vegetative parameters followed by the same concentration as foliar spray then followed by 500 ppm amino acids as soil drench or foliar spray. On the contrary, amino acids at 250 ppm and the two controls gave the lowest results in almost all cases. Root growth (root fresh and dry weight and root length) was improved in plants treated with amino acids compared to the controls of both seasons. Nitrogen and potassium accumulation was significantly increased by the different concentrations of amino acids application compared to the control. Whereas, phosphorous and total carbohydrate level increased by the lower concentration (250 ppm) compared with the other treatments. These aquired results on Schefflera actinophylla suggest that there is a definite positive effect of amino acids on both vegetative parameters andnutrient uptake and assimilation. This, in turn, leads to the idea to confortably recommend the application of amino acids (as Amino Zeid) at the rate of 1000 ppm preferably by foliar spray to promote growth and quality of Schefflera actinophylla bearing in mind that amino acids are natural substances and safe to the environment.
