Effect of foliar application of different fertilizers on growth and leaf nutrients content of lime (Citrus aurantifolia L.)‎ plants grown under nursery conditions

الملخص EN

The effect of foliar application of Fetrilon-Combi2, Compound Cryst and Foliar-X fertilizers on growth characteristics and leaf nutrients content of lime plants grown under nursery conditions was investigated.

Foliar fertilizers were sprayed every 15 days during the study period of 7 months.

The growth parameters were evaluated in terms of plant height, stem diameter, number of leaves, leaf size, growth index, and fresh and dry weights of different parts of the plant (leaves, stems and roots).

Leaf N, P, K, Ca, Mg, Fe, Zn, Mn and Cu contents were determined at the termination of the experiment.

The results revealed that all foliar fertilizers gave greater values of all measured growth parameters than the control.

Application of Foliar-X resulted in the highest values of most growth parameters, followed by Compound Cryst and Fetrilon-Combi2 fertilizers, respectively.

Significantly higher leaf- N, P, K, and Ca contents were detected in the plants sprayed with Foliar-X and Compound Cryst compared to the Fetrilon-Combi2-sprayed plants and control.

Higher leaf- Zn, and Mn contents were found in the plants sprayed with Fetrilon- Combi2 than the other two foliar fertilizers tested.

Leaf-Mg, Fe and Cu contents showed no significant differences among the treatments.
