A field experiment for drip irrigation regimes and fertigation levels in mango in four-year-old trees of ‘Alphonso’ mango was conducted. There were three irrigation regimes in main plots namely I1 (16 L day-1 plant-1), I2 (20 L day-1 plant-1) and I3 (24 L day-1 plant-1) and four fertigation levels in subplots viz., F1 (50% RDF), F2 (75% RDF), F3 (100% RDF) and F4 (125% RDF) replicated three times in a split plot design. The results of the experiment revealed that among the irrigation treatments I3 – 24 L day-1 plant-1 – recorded the highest percentage of fruit set, fruit weight, number of fruits per tree, fruit yield per tree and quality characters like, TSS, ascorbic acid, sugar, carotenoids were also the highest in the same treatment.
On comparison of sub plot treatments, percentage of fruit set, fruit weight, number of fruits per tree, fruit yield per tree were recorded by the application of 100% RDF (F3) through fertigation. In the interaction effect, application of 100% recommended dose of fertilizers (120:75:100 g NPK/tree/year) along with 24 L day-1 plant-1 has resulted in the improvement of all beneficial parameters leading to enhanced yield and quality of mango cultivar ‘Alphonso’ under ultra high density planting.
