Abstract
Field experiments were carried out to study the response of passion fruit to irrigation and fertigation levels. Fruit number and yield (22.85 kg/pl) were higher with 50% evaporation replenishment rate (ER) as compared to 25% ER (18.84 kg/pl). The yield differences between 50, 75 and 100% recommended dose of fertilizer (RDF) was not significant (19.68 - 21.68 kg/pl). The response surface models fitted to the yield data indicated an optimum ER of 40 % and RDF 55%. The relative water content and leaf nutrient content was higher with 50% ER and the leaf water potentials recorded lower values with 50% ER. The total water use was 282.5 and 564 mm with 25 and 50% ER and the water use efficiency was 40 and 66 kg/ha-mm. The leaf nutrient content (N, P, K, Ca & Mg) were higher with 50% ER and 100% RDF.
