“…Whilst solar radiation is of course essential for photosynthesis, the oil palm's requirements, in terms of sunshine hours or photosynthetic active radiation (PAR) are poorly defined (Corley and Tinker, 2003;Paramananthan, 2003). Physiological models can be used to assess the effect of solar radiation on crop production (e.g., Hoffmann et al, 2014). Chan (1991) showed a decrease in yield of 4.8 t FB ha −1 year −1 with a decrease in solar radiation of 1 GJ m −2 year −1 for Malaysia.…”

a b s t r a c tIn the past decade, oil palm (Elaeis guineensis Jacq.) has become the world's most important oil crop. The large demand for palm oil has resulted in a rapid expansion of oil palm cultivation across the globe. Because of the dwindling availability of land in Southeast Asia, most expansion of the industry is expected in Central and South America and sub-Saharan Africa, where land with suitable agro-ecological conditions is available. Using Ghana as a case study, a method for evaluating areas that are both suitable and available for oil palm production is presented. Our assessment used spatial data and GIS techniques, and showed that areas with suitable climatic conditions (annual average water deficit <400 mm) is about 20% greater than was previously identified. The observed differences are the result of using different methods to determine suitability, and climate change. A major climatic factor limiting suitability for oil palm production in Ghana is the annual water deficit, with the most suitable areas located in the rainforest and semi-deciduous forest zones with higher rainfall in southern Ghana. Opportunities for large-scale oil palm plantation development is limited, however, because of the lack of availability of large and contiguous tracts of land that are required for commercial plantation oil palm development. A feasible strategy for oil palm expansion is therefore smallholder production, which can make use of smaller parcels of land. Alternatively, oil palm production in Ghana can be increased by yield intensification on land already planted to oil palm. This can also reduce the requirement for further land clearance for new plantations to meet the growing demand for palm oil. Such assessments will be essential for guiding government policy makers and investors considering investments in oil palm development.

“…Modeling efforts to simulate OP behaviour and development also exist but they are mostly focused on agronomic variables (e.g. carbon allocation, yield, fertilization) and neglect carbon/water relations and surface energy fluxes (van Kraalingen et al 1989, Combres et al 2013, Huth et al 2014, Hoffmann et al 2014, Fan et al 2015, Okoro et al 2017, Pardon et al 2017. Only recently, Meijide et al (2017) employed a land surface model adapted to OP (CLM-Palm (Fan et al 2015)) to simulate water/energy fluxes at two OP plantations but changes with comparison to native forests were disregarded.…”

Given their ability to provide food, raw material and alleviate poverty, oil palm (OP) plantations are driving significant losses of biodiversity-rich tropical forests, fuelling a heated debate on ecosystem degradation and conservation. However, while OP-induced carbon emissions and biodiversity losses have received significant attention, OP water requirements have been marginalized and little is known on the ecohydrological changes (water and surface energy fluxes) occurring from forest clearing to plantation maturity. Numerical simulations supported by field observations from seven sites in Southeast Asia (five OP plantations and two tropical forests) are used here to illustrate the temporal evolution of OP actual evapotranspiration (ET), infiltration/runoff, gross primary productivity (GPP) and surface temperature as well as their changes relative to tropical forests. Model results from large-scale commercial plantations show that young OP plantations decrease ecosystem ET, causing hotter and drier climatic conditions, but mature plantations (age > 8−9 yr) have higher GPP and transpire more water (up to +7.7%) than the forests they have replaced. This is the result of physiological constraints on water use efficiency and the extremely high yield of OP (six to ten times higher than other oil crops). Hence, the land use efficiency of mature OP, i.e. the high productivity per unit of land area, comes at the expense of water consumption in a trade of water for carbon that may jeopardize local water resources. Sequential replanting and herbaceous ground cover can reduce the severity of such ecohydrological changes and support local water/climate regulation.

ABSTRAKKeberadaan gulma di areal budidaya tanaman dapat memengaruhi pertumbuhan dan perkembangan tanaman utama, begitu juga pada tanaman kelapa sawit. Pemanfaatan bioherbisida dari limbah gulma saliara dapat menjadi metode alternatif untuk mengendalikan gulma tanpa merusak lingkungan, serta meningkatkan pertumbuhan dan perkembangan tanaman. Penelitian ini bertujuan untuk mendapatkan metode alternatif pengendalian gulma menggunakan bioherbisida, mengetahui pengaruh aplikasi bioherbisida terhadap populasi gulma serta pertumbuhan dan perkembangan tanaman kelapa sawit, dan mengetahui kandungan senyawa alelokimia pada bioherbisida saliara (Lantana camara). Penelitian dilaksanakan di Kebun Percobaan 2 Politeknik Kelapa Sawit Citra Widya Edukasi Bekasi, mulai bulan Juni 2017 sampai Juni 2018. Penelitian ini disusun dalam rancanganacak lengkap (RAL) non faktorialyang terdiri dari tiga perlakuan yaitu : A1 (tanpa aplikasi, kontrol), A2 (aplikasi herbisida Glifosat 1%), dan A3 (Bioherbisida Saliara 5%). Setiap kombinasi perlakuan diulang sebanyak 5 kali dan satu sampel sehingga terdapat 15 unit percobaan. Data dianalisis menggunakan ANOVA dan apabila berpengaruh nyata pada taraf 5% dilanjutkan dengan uji lanjut BNT (Beda Nyata Terkecil). Hasil percobaan menunjukkan bahwa aplikasi bioherbisida saliara dapat dijadikan metode alternatif pengendalian gulma di perkebunan kelapa sawit dan berpengaruh nyata terhadap daya tumbuh gulma pada 4 minggu setelah aplikasi. Berdasarkan pengamatan fisik, pertumbuhan dan perkembangan tanaman kelapa sawit dengan aplikasi bioherbisida secara umum menunjukkan hasil yang lebih tinggi dibandingkan perlakuan kontrol dan Glifosat. Kandungan senyawa kimia pada bioherbisida saliara adalah 2,63% Saponin, 5,73% Tanin, dan 0,17% Flavonoid. ABSTRACTThe existence of weed in plantation area could affect plant growth and development, as well as palm oil.The utilization of bioherbicide from saliara could be an alternative method for controlling weed without damaging the environment, and also increasing plant growth and development. The objectives of this experiment were to obtain the alternative method with using bioherbicide, to know the effect of bioherbicide application toweed population and also growth and development of immature oil palm, and to know allelochemicals content in bioherbicide saliara. This research conducted at Teaching Farm 2 Citra Widya Education Oil Palm Polytechnic Bekasi, from Juni 2017 until Juni 2018. This research was arranged in a factorial random block design with three treatmens, consist of A1 (without application, control), A2 (Glifosat 1%), dan A3 (Bioherbicide Saliara 5%). Each treatment repeated five times and one sample, so that there were 15 experimental units. The data was analysis of variance. If the analysis variance test result was significant at 5%, then it continued by Least Significance Different(LSD).The result showed that bioherbicide saliara could be as alternative method for controlling weed in palm oil plantation and has significant effect to weed growth at fo...
