ABSTRACT Three field experiments to investigate the partial nutrient balance (N and K) in cassava/soybean intercrop system were conducted at University of Nigeria, Nsukka in a derived Savannah location of South Eastern Nigeria. Effect of fertilizer rate, residual fertilizer and soybean residue management on growth and yield of soybean and cassava and soil nutrient reserve were studied. Soybean growth and yield were significantly affected by their varieties, fertilizer rate and cropping syste...
ABSTRACT This study determines the technical efficiency level and socioeconomic characteristics that influence the technical efficiency of yellow pepper farmers. Stochastic Frontier function that incorporated inefficiency factors was estimated using a Maximum Likelihood technique to provide estimates of technical efficiency and its determinants using data obtained from 60 Nsukka Yellow pepper farmers in Nsukka, Enugu State, Nigeria. The result shows that the mean technical efficiency was 70 ...
ABSTRACT This study was conducted to investigate the effect of dietary selenium (se) supplementation on the reproductive performance of sows, preweaning growth performance of their piglets, haematological and antioxidant status of pigs. Twelve (12) crossbred sows (Landrace × Large White) aged 1-2 years with an average body weight (BW) of 56.1 ± 5kg were randomly allotted to four treatment groups of three sows per treatment in a completely randomised design (CRD). The treatment groups compr...
ABSTRACT A study was conducted in the runoff plots at the University of Nigeria Nsukka Teaching and Research Farm, in 2010 and 2011 to monitor the changes in aggregate stability, and some selected physicochemical properties of Nkpologu sandy loam soil under different cover and soil management systems. The management systems were bare fallow (BF), grass fallow (GF), legume (CE), groundnut (GN), sorghum (SM), and cassava (CA) cultivation. Following the characterization of the soil of the study...

Specifically, it sought to ascertain fishery technologies received by GRP fish farmers; determine adoption of fish farming technologies by fish farmers; determine impact of extension services of GRP on socioeconomic condition of the fish farmers as at the year 2012; ascertain farmers’ perceived constraints to adoption of GRP fish farming technologies; asc...
ABSTRACT A 35-day experiment was carried out in a completely randomized design to determine the efficacy of two phytogenic feed additives as veritable alternatives to antibiotics using 320 dayold unsexed commercial Ross 308 broiler chicks. The chicks were randomly divided into four groups of 80 birds each and assigned to four isocaloric (12.60, 13.2 and 13.4 MJ/Kg AMEn) and isonitrogenous (25.0, 22.5 and 20.07 % CP levels) diets designated as follows: diet 1- maizesoybean based diet without ...
ABSTRACT Forest, which is a major source of resources in Nigeria, is currently facing accelerated degradation and depletion. The growing demand for ecosystem services from forests has led to over-exploitation of the resources, resulting in the extinction of some valuable species. This has continued to impact negatively on the capacity of the forests to mitigate climate change, conserve biodiversity, safeguard wildlife, and protect land and watershed. Approaches to forest management in Nigeri...
Abstract The study was designed to analyze the marketing of banana and plantain in Enugu State. The specific objectives were to: describe the socio-economic characteristics of banana and plantain marketers; identify the marketing channels for the crops, examine the structure of the marketing system for both crops, estimate their marketing margins at both wholesale and retail levels, estimate the rate of price transmission and market integration among banana and plantain markets, and identify...
ABSTRACT These studies on evaluation of cassava cultivars and intercropping with legumes as an integrated nematode control strategy in cassava production were carried out as 15 greenhouse/microplot and field experiments. Of the 200 cultivars screened for resistance to Meloidogyne spp., only 76 survived and from this lot only 3 lines 77/227, TMS30572 and 73/222, showed any resistance while 7 others namely NR8082, 75.668, 73/238 (Egbenegbe), 73/295, 73/118, 75740(Panya), 82/00661 and 73295B we...

The study was carried out in Taraba State of Nigeria in the year 2011. The population of the study comprises all heads of households in Taraba State. A multi stage s...
ABSTRACT Indiscriminate and uncontrolled mining activities give rise to significant negative environmental impacts such as pollution of water bodies and farm lands, thus leading to decrease in soil fertility and soil quality as well as land degradation and changes in landscape. Therefore, this research was conducted to evaluate the impact of solid minerals mining at the Enyigba Lead-Zinc mining district in Abakaliki L.G.A of Ebonyi State and to document the present state of soil physico-chem...

Abstract This experiments of this Research were conducted to study effect of the gamma irradiation doses on four genotypes of maize (Zea mays L.) (Var-113, Hudiba-1, Hudiba-2 mug45). The maize genotypes were subjected to four doses (50, 100, 150 and 200GY) of gamma irradiation including control. One laboratory and two field experiments were conducted. The laboratory experiment was conducted to study the germination percentage, shoot, root and shoot to root ratios of the germinated seedling. ...
ABSTRACT This study which lasted for 52 weeks investigated the effects of dietary Vitamin C (Lascorbic acid) and Vitamin E (dl- alpha tocopheryl acetate) on the performance of laying hens in the humid tropics. A total of 240 twenty-four week old Golden Neslink pullets were randomly selected from a flock of 550 birds and randomly divided into sixteen treatments of 15 pullets. The birds were initially vent examined to ensure that they were at point of lay before commencing the study. Each...
