Item EFFECT OF APPLICATION OF FERTILIZERS THROUGH DRIP IRRIGATION ON YIELD OF OIL PALM(2015-10) Maheswarappa, H.P.; Gawankar, M.S.; Haldankar, P.M.; Malshe, K.V.; Salvi, B.R.; Mahadkar, U.M.; Arul Raj, S.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.Item 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.Item Fertigation schedule for the cultivation of Tenera oil palm in Konkan Coastal Region of Maharashtra(2018) Gawankar, M.S.; Haldankar, P.M.; Malshe, K.V.; Arulraj, S.; Maheswarappa, H.P.Item Initial performance of ten oil palm cross combinations under three agro-climatic conditions in India(2016) Sanjeevraddi G. Reddi; Gawankar, M.S.; Maheswarappa, H.P.; Madhavi Latha, P.; Mathur, R.K.yielding new oil palm cross combinations, a field experiment was conducted in different agro-climatic regions of India viz., Zone No-10 Southern Plateau and Hills (Gangavathi, Karnataka), Zone No-12 Western Coastal Plains and Ghats (Mulde, Maharashtra) and Zone No-11 Eastern Coastal Plains and Hills (Vijayarai, Andhra Pradesh) involving ten cross combinations of tenera oil palm (NRCOP 1-10). The data from three locations over two years indicated that, significantly higher annual rate of leaf production per palm was recorded in NRCOP-6 (21.7) compared to NRCOP-3 and it was on par with other hybrid combinations. Significantly higher sex ratio was recorded with NRCOP-4 (63.1%) compared to NRCOP-1 (54.6%) and NRCOP-6 (54.8%) and was on par with other hybrid combinations.The hybrid cross combination, NRCOP-4 recorded significantly higher fresh fruit bunches (FFBs) yield 12.5 t ha-1 compared to NRCOP-1, NRCOP-3, NRCOP-7 and NRCOP-9 and it was on par with remaining hybrids and a similar result in bunch weight and number of bunches per palm was recorded. Pooled data on FFB yield for 2013-15 indicated that the hybrid combination NRCOP-4 which recorded higher FFB yield (12.6 t ha-1) at Gangavathi and at Vijayarai (22.6 t ha-1) have better prospects for adaptation under Tungabhadra command area and coastal region of Andhra Pradesh. For Konkan region of Maharashtra, the hybrid NRCOP-8 recorded the highest FFB yield.Item Intercropping in Young Oil Palm Plantation under Konkan Region of Maharastra, India(2018) Gawankar, M.S.; Haldankar, P.M.; Salvi, B.R.; Haldavanekar, P.C.; Malshe, K.V.; Maheswarappa, H.P.Item Nutritional requirement of oil palm in Konkan region(2010) Gawankar, M.S.; Gajbhiye, R.C.; Arulraj, S.A field investigation was undertaken under All India Coordinated Research Project on Palms at Agricultural Research Station, Mulde in Sindhudurg district of Maharashtra since 1989 to assess the feasibility of growing oil palm in Konkan region and to assess the fertilizer and irrigation requirement. Five years pooled data from 12th to 16th year after planting revealed that oil palm showed high degree of response to fertilizer and irrigation. Irrigation by drip system with a discharge of 70 l of water per day during post monsoon season and by giving NPK fertilizer @ 1200:600:2700 g per palm par year secured the total returns of Rs. 75,775 (with the FFB rate of Rs. 3,500/ t) with a benefit cost ratio of 1.86 over rain fed condition. In the present study, cultivation of oil palm with basin irrigation at 560 l of water at an interval of four days from cessation of monsoon along with NPK at 1200:600:2700 g per palm par year recorded total returns of Rs. 69,615 with benefit cost ratio of 1.74 over rainfed crop. Cultivation of oil palm under rainfed condition along with same fertilizer level earned total returns of Rs. 44,450 with benefit cost ratio of 1.0 and cultivation of oil palm as rainfed crop without fertilizer was not a profitable proposition. Based on the study, it is recommended that cultivation of oil palm under irrigation (either by drip or through basin) along with a fertilizer dose of 1200:600:2700 g per palm per year is beneficial under Konkan conditions.Item Trends in weather and yield changes in past in coconut growing areas in India(2009-06) Naresh Kumar, S.; Rajeev, M.S.; Vinayan; Nagvekar, D.D.; Venkitaswamy, R.; Raghava Rao, D.V.; Boraiah, B.; Gawankar, M.S.; Dhanapal, R.; Patil, D.V.; Kasturi Bai, K.V.Item Utilization of oil palm wastes for vermicomposting(2019) Gawankar, M.S.; Haldankar, P.M.; Maheswarappa, H.P.; Naik, N. M.; Salvi, B.R.; Nalage, N.A.
