Effect of Kappaphycus alvarezii sap (seaweed) on growth and yield of tomato was studied in field during kharif season of 2006-07. K. alvarezii sap, applied as a foliar spray (5.0%), increased yield of tomato fruit (60.89%) as comapred to control plants sprayed with water, attributed to increase in number of fruits per plant and size of fruit. With application of sap, fruit quality and also macro (13.24-67.50%) and micro (23.84-42.61%) elements content increase over control. Nutrient uptake by fruit and stoot was improved with foliar application of K. alvarezii sap. Plants receiving foliar applications showed resistance to leaf curl, bacerial wilt and fruit borer.
