Abstract: The present investigation was carried out on eighteen years old oil palm plantation at ICAR-Indian Institute of Oil Palm Research, Pedavegi, Andhra Pradesh with different methods and levels of irrigation water using crop factors to find out their influence on the physiological responses in relation to yield of fresh fruit bunches. The result obtained has indicated significantly highest relative water content (97.44%), photosynthetic rate (16.46µmol m-2 s-1) and stomatal conductance (0.307mol m-2 s-1) with micro-jet method of irrigation, whereas, significantly highest membrane stability index (25.26%) and chlorophyll content index (112.64) were observed with drip method of irrigation. Among the levels of irrigation water using crop factor 0.7 has recorded significantly highest photosynthetic rate (16.56 µmol m-2 s-1) and stomatal conductance (0.295mol m-2 s-1), whereas, relative water content (95.51%), membrane stability index (27.11%) and chlorophyll content index (126.25) were found significantly highest with crop factor 0.8. Among the interaction effects, significantly highest photosynthetic rate (18.73µmol m-2 s-1) and stomatal conductance (0.322mol m-2 s-1) were observed with micro-jet method of irrigation using crop factor 0.7, while the relative water content (98.00%), membrane stability index (28.85%), chlorophyll content index (127.96) and fresh fruit bunch yield were found significantly highest with drip method of irrigation using crop factor 0.8.
