ABSTRACT The study was conducted in three landing villages along the coast of Greater Accra Region of Ghana, namely; Ada, La and Bortianor from November 2018 to April 2019. The purpose of the study was to assess the abundance of jellyfish in beach seine landings. Biological data was obtained primarily from local fishermen who deployed beach seine net. The jellyfish families that were encountered were four in number and a total of 2,676 individuals from 72 beach seine hauls. These were; Catost...
ABSTRACT Sorghum is the second most important cereal crop after pearl millet in terms of area planted, production, and per capita consumption in Mali. Production of sorghum is declining due to several reasons including lack of sorghum hybrids and adapted varieties tolerant to drought. Evaluation of sorghum genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. The general objective of the study was ...
ABSTRACT Striga hermonthica (Del.) and low soil nitrogen (low N) are among the most important constraints to maize production and productivity in West Africa (WA). Knowledge and understanding of the inheritance of Striga resistance and low N tolerance in early maturing maize inbreds are invaluable in developing hybrids adapted to both low N and Striga-infested environments in WA. The objectives of the present study were to (i) assess the genetic diversity among the inbred lines using simple s...
Abstract Although IPM has been advocated as a means of reducing chemical insecticide application, adoption of IPM practices are however, inadequate in the Hohoe Municipality and this may be attributed to a number of socio-economic and institutional factors. The study therefore sought to determine the knowledge levels and use of IPM practices by rice farmers. Survey research design was used for the study. Multi-stage sampling procedure was used to select 120 rice farmers. Both descriptive and ...
ABSTRACT This study was conducted to assess the growth, nodulation and nitrogen fixing potential of some native multipurpose trees and shrubs. A total of fourteen species of indigenous leguminous trees and shrubs were initially screened for nodulation in three Ghanaian soils (Toje, Hatso and Alajo soil series), after 8 weeks of growth in nursery bags. The experiment was repeated with nine species of the tree/shrub legumes, this time under two levels of phosphorus (0 and 60 mg P/kg soil). The ...
ABSTRACT The effects of three maize varieties and two storage seasons on the population dynamics of Prostephanus truncatus and Sitophilus zeamais were observed in the traditional4Ewe’ barn on the field. Two local varieties, Dzolokpuita and Abutia and an improved variety, Abeleehi, were stored with the husk on, during the long season, and Abutia only during the short season, of the 1994/1995 storage period. Destructive sampling techniques were applied to obtain data at monthly intervals for...
ABSTRACT The study set out to identify agglomeration externalities in Ghana’s soybean sector and to assess soybean output elasticities with respect to input-use. The study also analyzed the technical efficiency levels in the soybean sector and the effect of agglomeration externalities on productivity and technical efficiency of soybean farms. The study identifies some components of agglomeration externalities across the soybean sector and defines agglomeration externalities by two indexes;...
ABSTRACT Niger’s rice production has not been able to match growth in demand. The slow growth in domestic rice production has been attributed to salinity, non-adapted germplasm, and low farmer adoption of improved varieties. This study was carried out to: determine farmers’ perception on influence of salinity in rice production and their preference for rice varieties in salt affected areas; identify potential sources of genes for salt tolerance from local and exotic rice germplasm; determ...
ABSTRACT Agriculture in Sub Saharan Africa (SSA) is under serious threat due to water shortage, population pressure and climate change. Cowpea, a protein-rich legume crop complements staple cereal and tuber crops in the diets of rural and urban people of the tropical and subtropical regions of the world. It therefore, plays a significant role in the sustainability of food and nutrition security in SSA. Cowpea, though reported to be inherently drought tolerant; but because it is mostly grown...
ABSTRACT Acaricides in tick control, had been thought to be in Africa the panacea for over a century. Environmental and economic constraints, development of acaricide-resistant strains due to acaricide misuse, have brought about the need for an alternative tick control strategy. The use of tick resistant cattle has then been advocated and echoed in the USA and Australia where it got its full expansion. In Africa, few works have been undertaken on tick resistance despite the fact that many tic...
ABSTRACT OF THE STUDY Dairying is a young and developing industry in G hana, and one o f the m ajor problem s it faces is the low dem and o f the m ilk produced. This is partly due to public concerns over the safety and quality o f the m ilk produced, and also the hygienic practices o f informal agents. However, the extent o f risks posed to hum an health by consum ption o f m ilk and dairy products in the country is not well docum ented. This project w as therefore carried out to study the ...
ABSTRACT This research was carried out to determine the growth performance, carcass characteristics and selected blood parameters of broilers fed increasing levels of corn cobs (CC) as a replacement (50% or 100%) for wheat bran (WB), with or without fibre degrading enzymes (E). A total of 175 day-old chicks were used in this trial which lasted 42 days. Birds were randomly allotted to five dietary treatments in a completely randomised design. Treatments were labelled as T1 (0% CC), T2 (3% CC),...
ABSTRACT The System of Rice Intensification involves transplanting single, young seedlings in wider spacing and in a square pattern, and an intermittent water application in the field. The conventional method involves broadcasting rice seeds or randomly (or densely) transplanting rice seedlings and flooding the field with water throughout the production season. Rice production in Ghana is primarily done using the conventional method of production. However, the conventional method of rice prod...
ABSTRACT The use of recommended agricultural practices such as the safe adoption of pesticides is influenced by several factors as identified in the evaluative frame of reference. These factors have often led to the existing gap between farmers‘ knowledge and pesticide use. The purpose of the study was to examine the contribution of socio-economic factors to the application of skills acquired through training on the safe use of pesticides in vegetable production in the Accra Metropolitan As...
ABSTRACT The present study quantifies the effects of the determinants of commercialisation of maize production in the East Akyem District of Ghana. The Tobit model is used. The conventional t-test is also performed to examine the differences between the characteristics of the commercial and non-commercial maize farmers in the East Akyem District of Ghana. The study observes, inter alia, that farmer age, marital status, time farmer spends on maize fanning, farming system, whether male family m...
