ABSTRACT

The present study was conducted 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), were observed in I2 (RDI at 100 % Ep) during both the seasons.The maximum total sugars (16.75% and 17.18%) was found with I6 (PRD at 75% Ep) maximum reducing sugars (5.57% and 5.81%) was noticed in I5 (PRD at 50% Ep) and the highest non reducing sugars (11.9%) (11.42%) noticed with I1 and I6 in 2013-14 and 2014-15 seasons respectively. The highest relative water content (74.95% to 54.04%) was noticed with I2 throughout the irrigation period whereas the lowest relative water content was found with I1 (45.86% to 26.76%). The maximum chlorophyll contents were recorded with I2.

Key words: Mango yield, PRD and RDI
