ABSTRACT The use of quality seed is a prerequisite for high vegetable productivity. The Ghana Seed Inspection Division conducts seed quality assessment to ensure that seeds meet minimum quality standards before they are certified to be sold to farmers. Poor seed storage practices and repackaging of certified seeds at retailers’ end could adversely affect seed quality before farmers purchase these for planting. Post-certification surveillance was undertaken to assess the quality of certified...
ABSTRACT A study was carried out in 2012 in a Sudan savanna ecology in Ghana aimed at identifying the optimal planting dates and suitable cowpea varieties for green pod production. Six planting dates were considered starting from the onset of the rainy season (20th June, 30th June, 12th July, 25th July, 2nd August and 12th August), and four improved cowpea varieties released by Savanna Agricultural Research Institute (SARI) of the Council for Scientific and Industrial Research (CSIR) a...
ABSTRACT A field experiment was conducted at the University of Ghana research farm to evaluate the influence of compost and Nitrogen fertilizer on soil improvement, growth and yield of maize (Zea mays L) and residual effects on cowpea (Vigna unguiculata (L) Walp) in a rotation. The study area is within the coastal savannah ecological zone of Ghana. Two separate experiments were conducted from July to November, 2016 and from December, 2016 to February, 2017. The experimental set up used was a ...
ABSTRACT The interaction of the fungus, Fusarium oxysporum f. sp. vasinfectum and the nematode, Meloidogyne incognita on wilt disease on „Essoumtem‟ and Clemson spineless was examined in pot and field experiments from September, 2016 to June, 2017 in the University of Ghana farms. The fungus used for inoculation of four weeks old „Essoumtem‟ and Clemson spineless seedlings for pot experiment and one week old „Essoumtem‟ and Clemson spineless seedlings for field experiment w...
ABSTRACT Two experiments were conducted at the University of Ghana Farm, Leaon and Plant Genetic Resources Research Institute (Bunso). The first o . , experiment was carried out at Legon from March, 2002 to October, 2003 to evaluate Ilcassava accessions. The criteria used for the evaluation were (a) tolerance to whitefly infestation and African Cassava Mosaic Virus (ACMV) disease infection (b) root tuber yield and starch yield characteristics. Based on the performance of accessions in Experim...
ABSTRACT Loss assessment helps to identify constraints affecting the production and therefore the productivity of food crops. Information on loss assessment will thus assist in possible interventions needed to improve productivity. Quantitative losses associated with the production of rice (var. Jasmine 85) in the Kassena Nankana West District of the Upper East Region, one of the major rice producing areas in Ghana has not been adequately documented. A semi structured questionnaire was used t...
ABSTRACT Production of tomato in Ghana is threatened by plant parasitic nematodes. Identification of the types, distribution and population densities of these parasites is indispensable for the design and implementation of a proper nematode management practice. A study was conducted to: assess farmers' knowledge and perception on plant parasitic nematode occurrence and management on their farms in nine communities of Ashanti, Brong Ahafo and Upper East Regions ...
ABSTRACT The citrus gummosis disease is a major problem facing the Agriculture Research Station of the University of Ghana at Kade. The disease is the cause of death of citrus plants on the station, hence this work initiated to investigate the cause(s), possible contributing factors and its control on the station. A field survey conducted from January to June 1996 gave 36.2 -79.9% incidence (Avg. 62.6%) on six orchards of the station and an average severity index of 1.2 on a 0-5 scale....
ABSTRACT The popularity of cucumber has been on the increase over the years due to its nutritional and economic benefits. A field experiment was conducted at Teaching and Research Farm, Federal University Oye-Ekiti, (Longitude 708070N, latitude 504960E) to evaluate the influence of companion plants on the yield and post-harvest quality of cucumber. The hybrid cucumber seeds were bought from Agro-dealers in Akure. The companion crops which include sunflower, mint and marigold seedlings were ob...
A field experiment was conducted to investigate the comparative effects of organic and inorganic soil amendments on growth and performance of plantain (Musa paradisiaca). The experiment was established in March 2011 and repeated in February 2012. The treatments consisted of nine soil amendments (NPK sole, Jatropha sole, palm kernel cake (PKC) residue sole, Sunshine organo-mineral sole, NPK + Jatropha husk 50:50, Sunshine organo-mineral + Jatropha husk 50:50, PKC residue + NPK 50:50, PKC resid...
ABSTRACT Groundnut samples collected from commercial markets in South–Eastern Nigerian were examined for seed borne fungi organisms and their level of losses were quantified. Results obtained showed that only about 29% of groundnut seeds were without damage. This high rate of damage is a major factor in low viability of groundnut seeds in South – Eastern Nigeria. From the survey of groundnut seed cultivars, two cultivars: Spanish 205 (nwaerente) and Samnut 21 (Ngwongworo) were observe...
