Palm oil is nowadays the first vegetable consumed worldwide. Given world population growth and increasing demand in fat for food fuel, increase palm production expected to continue. It thus important find ways of reducing ecological impact plantations at both agroecosystem mill supply area levels, by improving agricultural practices land uses. This where agroecology can play a very critical role. The present article gathers short stories on agroecological currently taking place South-East...
The rapid growth in oil palm production has raised environmental concerns due to the massive discharge of liquid and solid waste. To address this issue, waste generated need be optimized by composting converting into organic fertilizer. practice pure inorganic fertilization must also discontinued rising cost imported fertilizers their detrimental effect on soil. Furthermore, several studies have established that recycling self-produced as fertilizer is an excellent method achieve...
A range of various different planting distances (from 7.5 to 9.5 m) between oil palms were tested using an equilateral triangle design in a plantation density experiment which was settled palm commercial Nigeria. Climatic conditions quite stable, with two seasons and around 2000 mm annual rainfall. The soil desaturated ferralitic type, sandy on the surface, deep without coarse elements. early impact analysed at eight years after planting. Some signs depressive effect yields found for high...
This article follows on from an earlier one about the same experiment in 2014. A range of various planting distances (from 7.5 to 9.5 metres) between oil palms was tested using equilateral triangle design. The current density set up palm plantation Nigeria. climatic conditions are quite stable, with two seasons and around 2000 mm annual rainfall. soil is desaturated ferralitic type, sandy surface, deep without coarse elements. After twelve years continual monitoring extrapolation results...
Predicting the fertilizer requirements of an oil palm plantation has long been a difficult task. Two main methods have emerged. Leaf analyses (LA) were used for fertilization management as early 1950s. contents are compared to optimum references, making it possible adjust rates applied in each block. Another approach, based on nutrient balance (NB), is evaluate and replace nutrients that exported from field, or immobilized by plant. Plantations must adopt environmentally friendly practices;...
SUMMARY We demonstrated experimentally that coconut husk ash is an excellent mineral fertilizer for immature hybrids on developed peat, providing potassium (K) in particular. Coconut performed as well chloride (KCl) a proportion of 2–2.5 to 1. At four years, 99% palms fertilized with ash, 92% KCl and 26% control were sexually differentiated. The cumulative yield the first two harvesting years more than trebled between (26 nuts per tree) (93 or (105 tree). This important result, given...
SUMMARY Potassium chloride (KCl) is the most widely used fertilizer in oil palm ( Elaeis guineensis ) plantations and rates applied are based on interpretation of leaf K contents. When no positive response contents can be detected, optimum content established whatever yield to KCl rates. We data from 13 fertilization trials conducted several continents study responses K, Cl, Ca as a function soil properties each site. found that abundance exchangeable expressed percent cation exchange...
AbstrakMinyak kelapa sawit adalah minyak nabati yang paling banyak dikonsumsi dunia. Setengah dari produksinya berasal Indonesia, walaupun perluasannya telah dikritik sudut pandang lingkungan. Pengurangan dampak lingkungan perkebunan melalui praktik pengelolaan limbah lebih baik sangat penting untuk mencapai produksi bersih. Dalam konteks ini, penelitian difokuskan pada pengomposan, semakin diterapkan di agroindustri. Penelitian bertujuan menguji pengomposan produk samping pabrik yaitu...
We demonstrated experimentally that Sufetula , a root-mining insect, has depressive effect on coconut yields peat soils. The impact of the pest resulted in shortfall earnings warranted taking control measures. considered methods suitable for rehabilitating infested mature plantings and preserving young plantings. Currently, cultural is only effective method. It involves eliminating all identified shelters adult i.e. fern cover heaps waste (dry fronds husks). aim to achieve totally bare soil,...
The nut yield and fruit composition of mature (30-40 years old) West African Tall coconut palms were evaluated in seven trials during the first three (from June 2000 to May 2003) implementation a five-year fertilization schedule recommended Coconut Sector Development Project (CSDP) for rehabilitation old farms coastal belt Western Region Ghana. are located at Jeway Wharf, Takinta, Ellenda, Nawule, AB Bokazo, Anwia Edwakpole. Three fertilizer treatments applied between 2003. two fertilizers...
We compared four oil palm ( Elaeis guineensis Jacq.) progenies’ morphological growth characteristics to reveal genotypic differences in plant and assess their adaptability Nigeria’s environment response different levels of potassium chloride (KCl) kieserite fertilizer applications. The studied progenies (C1, C2 C3 Deli × La M é origin C4 Yangambi origin) represent a wide genetic diversity have shown among population 116 progenies, contrasting K Mg leaflet concentrations that covered the...
On a large coconut plantation planted on deep peat soil in Sumatra, Indonesia, hybrid yields are stabilizing at values well below their potential, even plots where known production factors have been mastered since the outset: land preparation, water control, and mineral fertilization. To explain this situation, five hypotheses proposed. They were tested one by field trials. The authors demonstrated that main reason for stabilized was Lepidoptera root pest Sufetula spp. conclude considering...
The study of interactions between cacao ( Theobroma ) and coconut Cocos nucifera in Lampung, Indonesia, examined different combinations age, plant lay-out, planting chronology choice material under changing environmental conditions. Four coconut-cacao intercropping trials were used to assess the performance each intercrop limiting or non-limiting In experiments with young trees palms, delayed tree development reduced yields observed. When palms aged five years over, growth satisfactory...
Evaluation of four coconut management options was carried out from May 1999 to 2004 in the belt Western and Central Regions Ghana for replanting plantations devastated by Cape St Paul Wilt Disease Ghana. Coconut hybrid identified MYD x VTT. On fertile soils just intercropping inter-rows with food crops proved appropriate managing successfully. low however, fertilization required addition proper hybrid. Where intercrops were fertilized palms benefited residual effect. While Pueraria...
Copra yield in Papua New Guinea is estimated at 0.6 tonnes per hectare year. Several factors may be responsible for this low productivity compared to other Asia Pacific countries. Amongst these, nutrient deficiency an important limiting factor. In order evaluate coconut nutrition status PNG, leaf sample collection was undertaken by examining 23 sites around the country and from a trial carried out Stewart Research Station of PNG Cocoa & Coconut Institute (PNG-CCRI) Madang Province....
