Abstract : Growth, total chlorophylls, N, P and K in the leaves, yield and fruit quality of Keitte mango trees in response to foliar application of three organic manures tea (farmyard manure, compost and chicken manure), seaweed extract each at 10% and Royal jelly at 0.05%, singly or in combinations were investigated during 2013 and 2014 seasons. The trees received three sprays from these biostimulants at growth start, just after fruit setting and at one month later. Single and combined applications of all organic manure tea, seaweed extract and Royal jelly was very effective in stimulating all parameters comparing with the control treatment. The best organic manure tea in this connection was chicken manure, followed by compost and farmyard manure, in descending order. Combined application of any one of organic manure tea either applied with seaweed extract at 10% or with royal jelly at 0.05% was preferable than using organic manures tea alone in this respect. The best results with regard to yield and fruit quality of Keitte mango trees were obtained due to treating the trees three times with a mixture of chicken manure tea at 10% plus spraying Royal jelly at 0.05%.
