Aims: Cowpea’s use as leafy vegetable has been widely neglected in research. The present study was aimed at finding out the nature and magnitude of genetic variability in dual-purpose cowpea for leaf yield and quality attributes. Place and Duration of Study: Ngaoundéré University...
The study was designed to investigate the effect of Fadama II project on the performance of fish farming in Imo State. A sample of 30 fadama fish farmers and 30 non-fadama fish farmers were selected by multistage random sampling technique. Data were collected with a well structur...
Application of exogenous gibberellic acid stimulates high production of hydrolytic enzymes in malts. To investigate this effect on rice malt, different concentrations of the GA3 hormone were applied with the aim of establishing the optimum level that significantly affects rice ma...
Agrochemicals which ushered in the ‘green revolution’ in the 1950-60’s, boosted food productivity, but at the cost of environment and society. It increased food production but also destroyed the ‘physical, chemical and the biological properties’ of soil over the years of use. It...
Protection of pathogen-free olive planting material from infection by Verticillium dahliae during plant propagation and/or at planting would help in the management of Verticillium wilt of olive. Despite the importance for rhizosphere functioning, rhizobacterial Pseudomonas spp. h...
Tracheomycosis (or Coffee Wilt Disease) is a vascular disease that causes damage in plantations up to 80% of production in the absence of treatment. The fungus of the disease is Fusarium xylarioides. An experiment in micro-plots was put in place to look for 9 strains of this spec...
Verticillium dahliae Kleb. the causal agent of vascular wilt is an important pathogen of olive trees in growing areas of the world. To evaluate the reaction of the susceptibility of different commercial olive cultivars to the pathogen, six months old of eight commercial olive cul...
The effect of planting date and boll position on cell wall thickening of cotton fiber and development of fiber strength were studied by comparing the time course of the activity of key enzymes β-1,3-glucan synthase (callose) and sucrose synthase (SuSy) involved in cellulose biosy...
Ten eggs each from avian species: duck, local fowl, exotic fowl, pigeon and guinea fowl were analyzed for protein, phospholipids, cholesterol, vitamins and some mineral elements using standard methods. Total lipids were high in duck (2.9±0.07mg/g) and local fowl eggs (2.0±0.04mg/...
This study carried out an economics of insecticides usage among cowpea farmers in Kaduna State. Specifically, the study estimated insecticides marginal productivity; the degree of response of demand for insecticides to changes in its prices and the return to cowpea production due...
The classical model of plant root nutrient uptake given by Nye, Tinker and Barber is modified and extended for pollutant uptake in plants. An explicit closed mathematical description is given for the uptake, by a single cylindrical root for all cases of practical interest, by so...
Yellow rust caused by Puccinia striiformis f. sp. tritici is undoubtedly, the most important fungal disease of wheat especially in Central and Western Asia causes significant annual yield losses. To investigate the population structure of the pathogen, isolates were collected fro...
Aims: In order to identify the best parents and hybrids for resistance to Bolting and Cercospora leaf spot 9 sugar beet O-type lines in format method of Diallel 9×9 were crossed. Study design: 9 Sugar beet O-type lines in format method of 9×9 4 Diallel crossing was performed usin...
Anatomical alteration of leaf tissues components were investigated in regards to adequate and inadequate watering in Mungbean, Vetch and three Lentil cultivars namely Baraka, Adlib and Nineveh. The possibility of mitigating the alteration of these adversities by the aid of GA3 wa...
