    Oil Palm is recognised as the major source ofvegetable oil with an average oil yield level of 4to6tons perhectare.Howeyer,thecrophasheavyIlutrientdemandand highdegree ofsensitivity.. to major nutrients like N, P and K. Nevertheless, considering the importance of this crop as a potential long term source of edible oil, a field inve§tigation was conducted with a view to study the effect ofapplication of major nutdents through d'fi"p irrigation on yield oftenera oil palm in Konkan coastal region ofMaharashtra. Six different dosage offertilizers were followed through drip system by means of venturi and compared with fertilizer dose of 1200: 600: 2700 g NPKI PalmNear through soil application. The experiment was carried out on 18 years old tenera oil palm orchard. The results of the pooled yield for three years by considering first three years after introduction of fertigation as a transition period indicated that fertilizers @ 1200: 600: 1800 g NPKlpalm/year through six equal splits in a year in the form of Urea, Diammonium Phosphate and Muriate of potash through feritgation recorded highest bunch weight (25.0 kg/ bunch), highest number of fresh fruit bunches (5.2 bunches/palm/year) and 18.8 tons of fresh fruit bunch yield.

    EVALUATION OF OIL PALM HYBRIDS FOR PRECOCITY IN KONKAN CONDITIONS OF MAHARASHTRA
    (2016-01) Maheswarappa, H.P.; Gawankar, M.S.; Haldankar, P.M.; Mathur, R.K.; Mahadkar, U.M.; Arul Raj, S.
    Oil palm hybrids of Dura X Pisifera, were evaluated under Konkan conditions of Mahar'ashtra for three year's from 2013 to 2015. Significant var'iation for number of leaves, weight of bunch and yield of fresh fruit bunch (FFB) was recorded. Among the hybrids NRCOP4 and NRCOP-5 registered minimum height (2.4 m) during the year 2015 and maximum sex ratio above 50 percent. The average sex ratio for' population was 49.2 per cent. The hybrid NRCOP-2, NRCOP-8 and NRCOP-5 had more number of female flowers than male flowers. There was significant variation among hybrids for leaf production and for FFB yield. The hybrid NRCOP-2 r'ecorded highest yield during 2015 (12.8 t/ha-I) and average of7.3 tonnes per hectare over the years. Among the r'emaining hybrids NRCOP-l (9.7 t/ha-l), NRCOP-8 (9.6 t/ha-I) and NRCOP-9 (9.5 t/ha-I) were also found promising for FFB yield during 2015, Three years average perfor'mance exhibited that NRCOP-2 was most pr'omising hybr'id followed by NRCOP-8, NRCOP-9, NRCOP-6 and NRCOP-7 under Konkan agro-c1imatic conditions of Maharashtra.
