Influence of leaf urea sprays on leaf burn and on leaf, stem and root yields and nitrogen contents of citrus cuttings


Influence of leaf urea sprays on leaf burn and on leaf, stem and root yields and nitrogen contents of citrus cuttings



Spec. Rep. Univ. Calif, Los Angeles, 1, 162-73



Biuret-free urea sprays applied to the leaves of rooted lemon cuttings growing in sand and water cultures resulted in increased N contents in leaves, stems and roots. Urea sprays increased growth when the N supply to the roots was low, but slightly reduced growth when the N supply to the roots was high. The addition of sugar to the sprays reduced both urea absorption and leaf burn.
