Response Surface Models in High Density Mango Under Fertigation

Field experiments were carried out at the Horticultural Experiment Station, Bangalore, India, during 2004-2006, to study the response of mango to irrigation and fertigation levels. Fruit number and fruit yields were higher with 50% Evaporation Replenishment rate (ER) as compared to 25% ER. The yield differences between 100% Recommended Dose of Fertilizer (RDF) and 75% RDF were not significant. The response surface models fitted to the yield data indicated an optimum ER of 42% and RDF of 62%.
