ABSTRACT Modified three - way crosses involving advanced interspecific tomato hybrids (F12) and commercially cultivated tomato varieties namely Supersteak (S), Beef (Florida) (BF) and Plumb (Rio grande) (PR) were made to generate F1 hybrids. The F1 hybrids were crossed to both the pollen and seed parents to produce the backcrosses and were also allowed to random mate to produce the F2 and F3 populations. The parents, F1s, F2s, F3s and backcrosses were evaluated under rainfed conditions. Flora...

ABSTRACT The basic tenet of the study was that intra-industry trade occurred when commodities of the same industry are simultaneously exported and imported by partner nations within the sub-region. The objectives of the study were to review Nigeria’s merchandise trade, assess the simultaneous exports and imports of agricultural products by partner nations, evaluate the share of intra-industry trade in agricultural products between Nigeria and the ECOWAS partner nations, and determine the ef...
ABSTRACT Field trials were conducted in 2012 and 2013 cropping seasons on a naturally heavily striga infested field at the research farm of Federal University of Technology, Gidan kwano campus Minna to evaluate the effect of seed treatment, sowing date and trap crop in the management of Striga hermonthica. The experiment consisted of two varieties of sorghum (resistant ICSV1002 and susceptible Gwari local varieties), three different concentration of Parkia pulp powder (0, 66 and 100 g/l) and ...
ABSTRACT Fifty hens and five cocks from a random mating population of light local chicken ecotype (LLCE) were mated and the fertile eggs hatched to obtain the parent generation (G0) used for this study aimed at improving egg production traits in the LLCE using a selection index. The hens were monitored for short-term (90-days from first day of lay) egg production traits namely: Body Weight at First Egg (BWFE), Average Egg Weight (AEW) and Total Egg Number (TEN). Data obtained were subjected t...
Abstract This research was designed to determine and compare the technical efficiency and input levels used in rice production under farmer managed irrigation systems (FMIS) and rain fed systems (RFS) in Kogi State. It also compared the effects of socioeconomic characteristics on the technical efficiency of farmers in the FMIS and RFS. Four null hypotheses were tested. The study was conducted in commercial rice producing areas of Kogi State. It adopted a multi stage purposive sampling techniq...
Abstract This study investigated gender and climate change adaptation decisions among farm households in Southwest Nigeria. In carrying out the study, five specific objectives and five hypotheses were developed to guide the study. Multi-stage random sampling techniques were employed in selecting the 348 farm units for the study. Data for the study were obtained from primary source using structured questionnaire. Data collected were analysed using descriptive and inferential statistics such as...
Abstract The study analysed off-farm income and farm capital accumulation among small-scale farmers at farm level in North Central Nigeria. Multistage sampling technique was used to select 360 respondents, comprising participants and non-participants in off-farm work. The participants were disaggregated into three main typology namely, agricultural wage, nonagricultural wage, and self-employments. Data for the study were obtained from primary source with the aid of standard questionnaire and ...
ABSTRACT One mechanism by which plants can mobilize organic and inorganic forms of phosphorus (P) in soils is by exudation of low molecular weight organic acids. Laboratory and field trial were carried out during 2011 and 2012 cropping seasons to study the effects of additions of organic acids ( citric, oxalic and tartaric acids) on the mobilization of phosphate of soils from Minna and Mokwa, both in Southern Guinea Savanna of Nigeria. For initial laboratory studies and prior to field cultiva...
Abstract The overall purpose of the study was to determine the perception of extension staff of manpower and institutional factors that constrain agricultural extension services in Benue State Agricultural and Rural Development Authority (BNARDA). The study was guided by three research purposes, namely: to describe the respondents’ socio-economic characteristics; to determine the perception of the extension staff on the number of extension staff as a manpower constrain; and to examine the e...
ABSTRACT This study was conducted to investigate the effect of 45 and 60 minutes of exposure of crossbred (LW x Local) and exotic (LW) boars to tropical solar radiation on their body temperature pattern, libido, semen quality and haematological profile. 12 LW x Local and 12 LW boars of 10 months old were used for the experiment. The experiment was carried out in the Piggery Unit of the Department of Animal Science Farm, University of Nigeria, Nsukka for a period of eight weeks (4 weeks for th...
ABSTRACT The study ascertained indigenous and emerging adaptive agricultural technologies to climate change in the Niger Delta region of Nigeria. Data were collected from 400 respondents through the use of semi structured interview schedule using a multi stage random sampling technique. The collected data were analyzed using percentages, mean score, and factor analysis. The findings revealed that majority (89.8%) of the respondents were aware of climate change though only 9.0% of them knew of...
Abstract This study examined the contributions of women to household farming decisions among cocoa-based agroforestry households in Ekiti state, Nigeria using cross-sectional data. The study used purposive, multistage and random sampling techniques for the selection of 120 cocoa-based agroforestry farm units that constituted respondents for the study. The analytical techniques involved descriptive statistics, exploratory factor analysis and multinomial logistic regression model. With regards ...
ABSTRACT Plukenetia conophorum Muell Arg commonly called African walnut is cultivated principally for the nuts which are cooked and consumed as snacks. The plant serves many nutritional and medicinal purposes yet its availability is on the decline. To preserve and ensure continued availability of P. conophorum, there is the need to develop propagation protocols for the plant. Five accessions were collected from Mbu, Nsukka, Orba and two locations in Edem-ani all in Enugu State, Southeastern, ...
Abstract Grapefruit (Citrus paradisi Macf.) is an important crop in Sudan. The quality of grapefruit is affected by many factors which are suspected to cause the low yield and poor quality of fruits. These factors may include infection by pests and diseases, damage, soil problems and poor management practices. The present study aimed to identify the specifications of two grapefruit cultivars (Foster and Duncan).This was achieved through determining quality indices such as, number of segments,...
