Abstract: High yielding hybrids play an important role in increasing the yield and oil in the oil palm. With a view to develop and evaluate high yielding new oil palm cross combinations, a field experiment was conducted in AICRP On Palm (Oil Palm), ARS, Gangavathi, UHS, Bagalkot (Karnataka) to evaluate the ten new hybrid cross combinations of oil palm (NRCOP 1 to 10). Hybrids were planted during 2007 in a replicated trial. Managed with recommended package of practice (1200:600:1200 g N, P2O5, K2O per plant per year and irrigation based on potential evapotranspiration). The average data of all five years indicated that, significantly higher annual rate of leaf production recorded with NRCOP-2 &1, 4 (18.10) & (18.02) over NRCOP-7 & 6 (16.76) & (16.86) and it was on par with NRCOP-10(17.88) & NRCOP-3(17.40) hybrid combinations. Numerically higher sex ratio was recorded with NRCOP- 7 (0.66) over other hybrid combinations. With regard to FFB yield (average of all five years) the hybrid cross combination NRCOP- 4 recorded significantly higher FFB yield (14.66 tha-1) over, NRCOP-3 (10.98 tha-1), NRCOP-1(11.22 tha-1) and it was on par with remaining hybrids and similar results in Bunch weight and number of bunches per palm was recorded. Pooled data on FFB yield for 2013-2017 indicated that, the hybrid combination NRCOP - 4 recorded higher FFB yield (14.66 tha-1) at Gangavathi and appeared to have better prospects for adaptation under Tungabhadra command area.
