Popis:	Biochemical analysis of betel leaves infected by leaf spot and blight caused byXanthomonas campestris pv.betlicola showed a decrease in moisture, chlorophyll, protein, phenol and total carbohydrate contents as compared with healthy leaves. The decrease in these five parameters was 31-42%, 29-70%, 20-79%, 30-53% and 53-87%, respectively. Application of 100 kg P2O5/ha gave maximum height of vine, number of leaves per vine and fresh weight of 100 leaves, as compared with treatments of 25, 50, 75 and 125 kg P2O5/ha. Except for 25 kg P2O5/ha, all treatments enhanced the keeping quality compared with the control (no P2O5). Incidence of bacterial leaf spot decreased significantly as phosphorus level increased.
