ABSTRACT
This experiment was carried out during 2013-14 and 2014-15 seasons on Banganpalli mango trees at Amarachintha village as adoptive on farm trail of CRIDA. The irrigation water requirement is determined by using average season wise pan evaporation data for that area. Different irrigation treatments viz.,T1 – No irrigation; T2 - RDI at 100 % Ep; T3 - RDI at 75 % Ep; T4 - RDI at 50 % Ep;T5 – PRD at 50 % Ep; T6 – PRD at 75 % Ep. among all treatments, The maximum fruit number (139.5 and 129.0), yield per plant (52.9kg and 50.0kg), fruit weight (379.0g and 360.0g), pulp weight (288.27g and 274.0g), per cent pulp (79.38%), pulp to seed ratio (6.74 and 6.85) and least per centage of stone (11.80% and 11.45%) were observed in I2 (RDI at 100 % Ep) during both the seasons. The maximum total soluble solids (18.5 0Brix and 19.0 0Brix) and less acidity (0.38% and 0.36%) was noticed with I4 (RDI 50 % Ep).
Key words :
Mango, PRZ and RDI drying, Yield & quality attributes.
