Abstract

A experiment was conducted on 7–9 year-old bearing Nagpur mandarin (Citrus reticulata Blanco) based on evaporation replenishment (ER) irrigation scheduling to identify the irrigation water requirement through drip irrigation system during 2009–2012 at different stages. The fruit and quality was found significantly influenced under various evaporation replenishment (ER) based drip irrigation scheduling treatments. The highest fruit yield (21.48 tonnes/ha) was observed under irrigation at 80% ER in stages I-V and 30% ER in stage VI. Among the fruit quality irrigation scheduled at 80% ER in stages I-V and 30% ER in stage VI produced higher TSS, juice content and lower acidity. The highest TSS: acid ratio (12.7) was found in the irrigation scheduled with 30% ER in stage VI and 80% ER in stages I-V followed by the drip irrigation scheduled with 80% ER in all I-VI stages (12.2).
