Adoption of the cocoa (Theobroma cacao) production technologies recommended to farmers by Cocoa Research Institute Ghana (CRIG) had been low, leading yield and levels below potential. To investigate this issue, a formal socio-economic sample survey 300 selected randomly, multi-stage sampling technique, from all growing regions was conducted with structured questionnaire for individual interviews. The adoption rates CRIG-recommended such as control capsids insecticides, black pod disease...

Descriptive inferential analyses survey data performed. Regression analysis employed...

The cacao swollen shoot virus disease (CSSVD) is among the most economically damaging diseases of trees and accounts for almost 15–50% harvest losses in Ghana. This transmitted by several species mealybugs (Pseudococcidae, Homoptera) when they feed on plants. One mitigation strategies CSSVD investigated at Cocoa Research Institute Ghana (CRIG) use mild-strain cross-protection against effects severe strains. In this study, simple deterministic, delay, stochastic ordinary differential...

Cocoa swollen shoot virus disease (CSSVD) is a major of cacao (Theobroma L.) in Ghana and other West African countries that grow the crop. Attempts to develop resistant varieties since discovery 1936 have yielded little success. Recently, planting materials are tolerant been recommended for areas with high CSSVD prevalence. However, effect on yield component traits most clones including has not well studied. To investigate impact these traits, reduction bean weight (BW), number beans per pod...

Broad sense heritabilities were estimated in three long-term cocoa clone trials Ghana, with 20, 18 and 15 entries. They 0.15, 0.05 0.15 for yield pods per plant, 0.26, 0.19 0.40 incidence of ‘bad’ pods, mostly due to black pod disease, caused by infection Phytophthora spp. The low heritability single plant yield, which has been known 80 years, widely overlooked research extension, compromising the success selection programmes. disease is high enough justify mass where family level data are...

A field trial was conducted at the Cocoa Research Institute of Ghana from 1992 to 2004 investigate prospects using Cacao swollen shoot virus (CSSV)-immune crops as a barrier prevent spread existing outbreaks into newly established cacao plantings. The treatments consisted four crops-citrus (Citrus spp.), oil palm (Elaeis guineensis Jacq.), kola (Cola nitida Vent.), and (Theobroma L.)-planted between trees serving test plants on one side source CSSV strain 1A infection other. Over 7-year...

Farmers' knowledge of major insect pests and their occurrence in cocoa plantations Ghana as well common practices farmers to control these were assessed. It was found that 52%, 41%, 74% the respondents could not recognize mirid bug (Sahlbergella singularis), stink (Bathycoelia thalassina), coreid (Pseudotheraptus devastans), respectively, when they saw insects pictures. Also, over 50% describe damage symptoms bugs. Farmers who accurately identified mostly observed a peak presence bugs...

Performance of Aqueous Neem Seed Extract (ANSE) at 75 g/L water (22.5 kg/ha) was evaluated on Legon I variety local garden egg in the field. The effect ANSE compared with a registered Bacillus thuringiensis Berl. (Biobit), synthetic insecticide (Karate 2.5 EC) and an untreated control (water only). Karate Biobit were applied rate ml/L (800 ml/ha) 0.8 (0.24 kg/ha), respectively. each treatment insect abundance, defoliators, shoot, bud fruit borers determined. Water traps used to monitor three...

Cocoa Swollen Shoot Virus Disease (CSSVD) has been of great threat to the Ghanaian cocoa industry since 1936. Eradication by cutting out and replanting affected farms main method controlling disease in Ghana. Also, considerable research efforts have yielded several recommendations that farmers are expected implement limit spread disease. However, keeps spreading new areas at an increasing rate. This study is first assess depth extent farmers' adoption recommended preventive treatment...

Increasing soil acidity is one of the major factors limiting crop production in Ghana. Hence, identifying cocoa varieties that are well adapted to acidic soils and better extractors important nutrients viz phosphorus (P) potassium (K) a suitable way optimize use improve production. A 4 × 12 factorial completely randomized design with four replications was used evaluate grown for following traits: height, stem diameter, root length volume, dry matter ,and nutrient uptake. No significant...

The growth response of mistletoe, Tapinanthus bangwensis (Engl. and Krause) Danser to different temperatures photoperiods on hormone-free culture media in vitro were assessed. Cultural procedure with plant sap extracts field infestations used study the mistletoe interaction Gliricidia sepium, Mangifera indica, Coffee robusta Theobroma cacao. In laboratory, responded positively a temperature range 25-30 °C 16-24 hr photoperiod. seedling stages germination, holdfast haustorium development leaf...

Cashew cultivation in Ghana has been seriously hampered by high cost of production. This necessitated investigation into practices that will reduce establishment and improve field performance cashew transplants. An experiment was conducted at Cocoa Research Institute Ghana’s (CRIG) substation Bole (9° 01' N, 2° 29' W, altitude 309 m a s l) for optimizing the size polybag to volume top soil required nursing seedling, ease seedling conveyance also plant establishment. seeds were sown polybags...

SUMMARY Data from three cocoa ( Theobroma cacao ) clonal selection trials are used to investigate the genetic and environmental components of variation in yield percentage total pods affected by black pod disease Phytophtora rot). Simulations based on these estimated then discuss best choice future numbers clones, replicates years harvest maximise advances traits measured. The main conclusions need increase number clones at expense each clone, diminishing returns additional harvesting...

Urea or sulphate of ammonia fertilizer application on cacao ( Theobroma L.) in Ghana has either caused no changes a decrease yields. In Ghana, soil diagnosis shown low N cacao‐growing areas, which could be limiting production. Alleviating the to increase yields without negative effects requires use an appropriate source and dose fertilizer. A study was conducted determine suitability calcium nitrate as right that will ensure yield. randomized complete block design with three replications...

Abstract Attempts to develop high yielding varieties in Ghana have mostly relied on the introduction of new clones broaden range planting materials for yield improvement.
