- Abstract
This experiment was conducted in March 1st, 2018 on in 3 months old Citrus aurantifolia L. seedlings to study the effect foliar spraying with Nano-fertilizer Optimus Plus and Potassium chelate and their interaction in some vegetative growth and plant content of chlorophyll and carbohydrates. The experiment was randomized complete block design (R.C.B.D) with three replicates and two factors, the Nano Fertilizer at four concentration levels (0, 0.5, 1 and 1.5 ml.L-1 and potassium chelate (0, 2, 3 and 4 ml.L-1). Means were compared among treatments using the least significant difference test (L.S.D) at 0.05 probability level. Results showed that all the tested plant growth indicators were significantly affected by treatment of Optimus Plus at 1.5 ml.L-1 which resulted in the highest values in seedlings height, number of branches, stem diameter, number of leaves, leaf area, leaf content of total chlorophyll and dissolved carbohydrates. Similar results were recorded in case of potassium chelate at the highest concentration (4 ml.L-1) which significantly differed from all the other potassium concentrations. However, interaction treatment of 1.5 ml.L-1 Optimus Plus and 4 ml.L-1 potassium chelate was the most effective treatment among all treatments and interactions and resulted in the highest values of all tested parameters. Over the untreated control, seedlings height, number of branches, stem diameter, number of leaves, leaf area, leaf content of total chlorophyll and dissolved carbohydrates were increased by 66.9%, 146.8%, 64.24%, 129.71%, 37.52%, 143.41% and 91.31%, respectively.
