EVALUATION OF HYT BIOFERTILIZERS AND BIOCHAR ON THE GROWTH CHARACTERS AND YIELD OF HOT PEPPER

ABSTRACT The research was conducted to investigate the effects of High Yield Technology (HYT) biofertilizers, biochar and inorganic fertilizer on the growth and yield of pepper. The studies were conducted at the University of Ghana Forest and Horticultural Crops Research Centre (FOHCREC), Kade from May 2011 to April 2012. The experiment consisted of three factors namely, HYT, Biochar and inorganic fertilizer at three levels each (HYT: 100%, 50% and 0%); Biochar: 7t/ha, 3.5t/ha and 0t/ha; inor...

INFESTATION OF PHASEOLUS VULGARIS (L) BY THE BEANFLY O P HIOMYIA SPP. (DIPTERA: A G R O M Y Z I D A E ) AND ITS MANAGEMENT BY CULTURAL PRACTICES

ABSTRACT Cultural practices as management strategy for beanfly control were examined over four cropping seasons in 1991 and 1992 under f a r m e r’s developed field conditions at Oyugis, in Homa Bay District of Western Kenya. In many parts of East and Central Africa, the beanfly is a major constraint to the production of the bean crop (Phaseolus vulgari s ), Its incidence causes yield losses averaging 47-87%, Control methods used against the pest are mostly insecticides based. Cultural cont...

EFFECTS OF SMALL-SCALE COCONUT OIL PROCESSING METHODS ON THE QUALITY AND YIELD OF OIL IN THE JOMORO DISTICT.

ABSTRACT Coconut (Cocos nucifera L.) is an important cash crop in the economy of the people living in the coastal belt of Ghana, specifically Jomoro district in the Western region. Coconut oil is essential for its unique nutritional and economic purposes; which contain medium chain fatty acid and used for pharmaceutical purposes. The quality of coconut oil produced by the small-scale processors cannot be ascertained, as quality control measures and oil recovery cannot be strictly assured. The...

EFFECT OF DIFFERENT MOISTURE AND SHADE REGIMES ON SEEDLING GROWTH OF THREE OIL PALM (Elaeis guineensis) PROGENIES

Abstract The effect of three different moisture and shade regimes on the seedling growth of three Dura x Pisifera oil palm progenies was investigated at the Oil Palm Research Institute, Kusi between July 1998 and February 2000. A split plot design with four replications was used. Data were collected on leaf number per plant, plant height, butt circumference and leaf area as well as dry weight of plant parts and total plant dry weight. Growth analysis was performed and correlation among traits...

MAIZE VARIETY AND POPULATION STUDIES IN A CASSAVA/MAIZE INTERCROPPING SYSTEM

The feasibility of intercropping cassava with high maize populations was also studied. A strip-split plot design with a parallel-row systematic arrangement in which five maize varieties, IK.84A-2135, IB84A-203 , TZSR-Y-1, 1368 x 5012 and 9450 x 4001 at five population densities of 10,000, 20,000, 40,000, 80,000 and 160.000 plants/ha i...

THE POTENTIAL OF Beauveria bassiana FOR THE MANAGEMENT OF Cosmopolites sordidus (Germar, 1824) ON PLANTAIN {Musa, AAB)

ABSTRACT The banana weevil, Cosmopolites sordidus (Germar) in association with other pests and diseases, represents a threat to the production of plantain (Musa spp., AAB), the preferred staple food in Ghana. Biological control of the banana weevil was considered the most promising management option for small-scale plantain production and studies were, therefore, undertaken to determine the efficacy o f the entomopathogenic fungus, Beauveria bassiana (Balsamo) Vuillemin in the management of C...

PESTICIDE USE PATTERN AND INSECTICIDE RESIDUE LEVELS IN TOMATO (LYCOPERSICUM ESCULENTUM MILL.) IN SOME SELECTED PRODUCTION SYSTEMS IN GHANA

ABSTRACT A survey of 120 tomato farmers under two production systems was carried out at Tono and Vea in the Upper East region, Derma and Techimentia in the Tano district of the Brong Ahafo region to assess farmers’ knowledge of insect pest problems, production systems and pest management practices with emphasis on pesticide use patterns. Residue levels of Lindane, Endosulfan and Chlorpyrifos insecticides in harvested tomato fruits from Derma, Techimentia, Tono and Vea areas were determ...

DIVERSITY OF Striga gesnerioides (L.) Walp ON COWPEA IN GHANA

ABSTRACT Striga gesnerioides is a devastating parasitic weed of cowpea, especially in Ghana and the rest of West Africa. It is the major cause of cowpea yield reduction in Ghana. Despite seven different races being known across West Africa, the races of the parasite present in Ghana and their diversity have not been studied. This study investigated the distribution and diversity of Striga gesnerioides on cowpea in Ghana. The study revealed widespread distribution of the parasite within the No...

DIALLEL A1~ALYSIS OF MAIZE INBRED LINES (Zea mays) FOR RESISTANCE TO STRIGA (Striga IIermolltllica)

ABSTRACT Striga hermollthica (De.) Benth. infest millions of hectares of land under cereals in sub-Saharan Africa, threatening food security. One of the major crops threatened i~ maize (Zea mays L.), a staple food for many Ghanaians. The objectives of this study were to investigate the combining ability and heritability of Striga-resistant maize inbred lines for the selection ofsuperior lines for hybridization. A diallel cross involving ten (10) maize inbred lines was made to produce forty-f...

Treatments in the first and second trials consisted of two factors: three levels of fertilizer (0-15-30 N-P2O5-K2O kg ha-1,), and four cassava based cropping systems. The behaviour of component crops in three row arrangements was evaluated in the third trial...

GENETIC DIVERSITY IN SOME LOCAL CASSAVA CULTIVARS IN GHANA

ABSTRACT The genetic diversity in 100 cassava accessions collected from eight regions of Ghana was assessed using morphological and molecular characterisation. Both qualitative and quantitative morphological traits were used to assess variability in the accessions. Canonical discriminant analysis of morphological data showed that quantitative traits detected more variability than qualitative traits. A set of 1 0 random sequence 1 0 mer oligonucleotide primers selected from among eighty th...
