- Abstract
The study included two experiments, the first laboratory and the second field experiment, for the period from 1/ 2/2018 to 1/11/2018. The laboratory experiment was performed in the laboratories of the College of Education for the Pure Sciences, University of Diyala, where ZnO have been prepared by using sol-gel method. the field experiment was conducted in the Agricultural Department of Diyala, inside the plastic house covered with polyethylene. The Capsicum frutescens plant was rotated into the pot Hydroponic system containing the medium of the perlite and the concentrations of 0, 25 and 75 mg/l were added of Nano zinc oxide to the nutrient solution of Capsicum frutescens plant. the experiment was designed in a completely randomized design (CRD) with three replication for each treatment and three samples for each treatment, this experiment included four different treatment, control treatment (without zinc), Cooper solution (with zinc) 25 and 75 mg/l ZnO. The comparison between the mean of the treatment was done using Duncan at 0.05 level of significance. The results showed that zinc oxide granular size of 2872. nm, as it was diagnosed using the technique of diffraction X-Ray and the use of the Debye – Scherrer equation. as well as that the prepared material of ZnO is pure material has been diagnosed using the Energy Dispersive X-ray Spectroscopy (EDX). Use of ZnO at 25 mg/l concentration caused significantly influenced in the leaves content of chlorophyll and at a rate of 112.7 SPAD unit compared with the control treatment, which gave a rate of 92.0 SPAD unit and the same treatment caused an increase in the percentage of nutrient concentrations in leaves at a rate of 3.19% for nitrogen, 0.41% for phosphorus, 1.21% for zinc and 19.9% for protein, while the control treatment gave a percentage of 2.0% for nitrogen, 0.38% for phosphorus, 0.88% for zinc and 12.7%, for protein, the same treatment showed an increased in the fruits content of vitamin C and increased the leaves content of Auxin at a rate of 36.0 mg/ml and 14.5 mg/kg, respectively, compared with the control treatment, which gave rate of 23.0 mg/ml and 9.4 mg/kg, respectively.
