ABSTRACT A pot experiment was carried out from 15th December, 2014 to 20th June, 2015 at the University of Ghana Forest and Horticultural Crop Research Centre (FOHCREC), Okumaning under greenhouse conditions in a randomized complete block design to investigate the influence of grafting on growth, yield, quality and shelf life of tomato grafted onto three solanum species. Two tomato varieties ‘Fadeεbege’, and ‘Nkansah HT’ were used as scions and three solanum specie ‘Gboma’, ‘Bl...

Effect Of Type Of Initiation And Growing Media On Growth And Nutrient Uptake Of Plantain (Musa Aab) At The Nursery Stage

ABSTRACT Plantain (Musa spp) is one of the most important food crops. A limiting factor to large-scale production and or expansion of existing plantation is the difficulty in obtaining adequate planting materials. Although the tissue culture technique provides a higher multiplication rate, facilities are non-existent, and if available, the cost will be expensive and unavailable to most farmers in developing countries such as Ghana. The split-corm technique is a cheaper method for raising plan...

THE USE OF BIOPESTICIDES TO CONTROL INSECT PESTS OF PAWPAW

ABSTRACT Laboratory and field experiments were carried out between June 1997 and Januaiy 1999 at Paradise farm near Nsawam in the Eastern Region of Ghana to determine the major insect pests of papaya, Carica papaya and to evaluate the effectiveness of Bacillus thuringiensis and neem seed extract for controlling the insect pests of papaya. Methanolic and aqueous neem seed extracts were tested at the following concentrations 0 , 50, 75 and 100 g/1. Bacillus thuringiensis was applied at the rate...

Ihtjit Setting, Imheritance Of Nut Colour, Germination And Early Seedling Growth Op Kola (Cola Nitida (Vent.) Schott And Endl

A B S T R A C T In a diallel cross involving six kola trees, two from each of the cultivars Laboshie white ex Nigeria, Kumasi white and Kade pink, a self compatible tree of the Kade pink cultivar was found to be the most efficient female but the least efficient male parent for fruit set. The frequency of red, white and pink nuts that segregated in the progeny of the various crosses suggests that a single locus with multiple alleles controls the inheritance of kolanut colour. At physiological ...

Diversity Of Cotton (Gossypium Spp.) Genotypes From The Guinea Savanna Zone Of Ghana

ABSTRACT The sustenance and progress of any breeding program and conservation of its germplasm is hinged on the ability to estimate the degree of genetic diversity in a given gene pool for maintaining crop production. Therefore, data on the genetic diversity and relationships among plant genotypes is vital to identifying the complexity of the gene pool, to ascertain breaches in genotype collections in order to develop effective conservation and management strategies. This study was conducted ...
