Abstract :

A cocoa-tood crop intercropping trial was set up in 1988 at the Cocoa Research Institute of Ghana, Tafo. The effects of plantain, cassava, and maize as intercrops with cocoa only and in their various combinations on the establ ishment, growth of the cocoa, and the profitability of the food crops were studied in a randomized block experiment with five replicates. Mixed hybrid cocoa seedlings we ...

Abstract :

Studies were conducted at the Cocoa Research Institute of Ghana, Tafo and its sub-station at Bunso, from 1994 to 1997 to re-appraise the success of cocoa etablishment from seeds sown at stake at specified times of the year before the onset of the dry season. The treatments consisted of four times within the year when seeds waesown at stake, namely April, June, and September. Seedlings raised i ...

Abstract :

The presence in cocoa (Theobroma cacao L.) of cocoa swollen shoot virus inhibitors, the effect of pre-germination of cocoa beans on infection with the virulent strain A of this virus, and the kinetics of symptom development in cocoa seedlings were studied by manual inoculation of germinated and ungerminated cocoa beans with partially purified virus preparations and by inoculation with virulife ...

Abstract :

The prospects for using Flemingia macrophylla and Mucuna prllriens in combination with manual weeding during the establishment of young cocoa was investigated. The following treatments were compared: Clean weeding three times/annum + F. macrophylla planted in the interrows of cocoa and biomass used as mulch; clean weeding of cocoa lines (1 m wide) three times/annum + Mucuna cover crop; and cle ...

Abstract :

A comparative growth analysis and N, P and K contents of six cocoa varieties grown in two cocoa-growing soils of different fertility status under greenhouse conditions were carried out over a period of 12 months. The cocoa varieties studied were inter amazon crosses, namely: T851 799 x Amel, T79/501 x T851799, T851799 x Pa7/808, APA 5 x Pa7/808, T60/887 x Pd 15, and T79/501 x ALPHA B 36. The e ...

Abstract :

Mature oil palms (Elaeis guineensis) at the Oil Palm Research Institute at Kusi, Ghana, were underplanted with cocoa (Theobroma cacao) to study the feasibility of mixed cropping of the two crops under West African conditions. The oil palm trees used in this trial were planted in 1970 and had achieved maximum canopy formation. Three triangular spacings of the oil palms were selected - 8.7, 9.9 ...

Abstract :

A severe black pod disease of cocoa in Ghana caused by Phytophthora megakarya was first reported in 1985, even though there is evidence that the fungus might have existed earlier. Until then. only Phytophlhora palmivora which' causes a less severe black pod disease was known in Ghana. P. megakarya has changed the status of black pod disease in Ghana, causing serious crop losses and great conce ...

Abstract :

Exportable cocoa beans are graded routinely at the port prior to shipment. There was no record of any analysis of the data collected. The present investigation sets out to assess the quality of cocoa beans season and to ascertain whether mouldiness significantly contributed to the defect observed in exportable cocoa. Sample of cocoa beans from consignments brought to the port for shipment were ...

Abstract :

Cocoa cultivation in Ghana is carried out in selectively thinned forest, with a number of forest trees left after clearing to provide permanent shade. Large amounts of forest land have become degraded during this process, and to prevent further exploitation of virgin forest land, strategies are needed for rehabilitating the degraded areas. These could involve manipulating native tree successio ...

Abstract :

The hexane-acetone method was used to measure the phospholipid P content of some cocoa soils. The values which ranged from 1_75µg P g-l soil to 12.93 µg P g-l are more in line with European levels than North American levels. Soil-extract dilution plates revealed 16 x 108 - 81 X 108 bacteria per gram in the 0-15 cm layer. Even though plant residues contributed significantly to the phospholipid ...
