Online published on 15 December, 2016. Abstract 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. Top Keywords Evaporation Replenishment, Photosynthetic rate, transpiration rate and Yield. Top |
