Effect of Different Levels of Stage Wise Evaporation Replenishment on Leaf Gas Exchange Parameters and Yield Characters of Papaya Through Drip Sysyem

Summary: The Field experiment was conducted at College Orchard, HC&RI, Tamil Nadu Agricultural University and Coimbatore. The variety Pusa Dwarf was subjected to various levels of 100, 80, 60, 40 per cent evaporation replenishment at different growth stages of the crop. High content of photosynthetic rate(12.4 μmol CO₂ m⁻² s⁻¹) and transpirtaion rate(10.49 mmol H₂O m⁻² s⁻¹) and yeild characters like First flowering height(81.8 cm), first fruiting height(90.6 cm) and number of fruits(107) and yield(35.5 Kg plant⁻¹) at all stage of the crop.
