COMPARATIVE EVALUATION OF SEASONAL DYNAMICS OF HEAVY METALS IN Nematopalaemon hastatus AND Farfantepenaeus notialis IN A TROPICAL BRACKISH ENVIRONMENT

Abstract The distribution and concentration of Cadmium, Copper, Iron, Lead, Manganese and Zinc in the cephalothorax and abdomen of two species of shrimps (Nematopalaemon hastatus and Farfantepenaeus notialis) in coastal waters of Ondo State, Nigeria were investigated from April, 2014 to March, 2016 using Atomic Absorption Spectrophotometer. The metal bioaccumulation level in the shrimps was […]

AGRICULTURAL MARKETING INFORMATION TRANSMISSION CHANNELS TO SMALLHOLDER ARABLE CROP FARMERS IN IMO STATE, NIGERIA

Abstract The utmost barrier to agricultural production in Nigeria is not absence of recommended practices, but inability of service providers to transmit relevant technologies through information channels available and adaptable to the local situations of end-users. This study therefore assessed agricultural marketing information transmission channels to smallholder arable crop farmers in Imo State, Nigeria. Specifically, […]

MODELLING OF THE TEMPERATURE-HUMIDITY INDEX (THI) AND VENTILATION PATTERNS IN THE RABBITS’ PENS

Abstract The research developed a model for the prediction of the Temperature-Humidity Index (THI) inside the rabbits’ pen resulting from combined effects of ventilation openings and building orientations on the performance of rabbit does.Three factors were considered in the study, namely; different seasons of the year (dry and rainy seasons),   building orientations (45o and 90o […]

THE In Vitro INHIBITION OF Macrophomina AND Lasiodiplodia SPECIES USING THREE MEDICINAL PLANT EXTRACTS

Abstract This study was, undertaken to investigate the in vitro anti-fungal activities of ethanol extracts of three medicinal plants (Azadirachta indica, Chromolaena odorata and Zanthoxylum zanthoxyloides) against Macrophomina phaseolina and Lasiodiplodia theobromae isolated from Jatropha curcas. Antifungal bioassays using pour plate method were carried out by using leaf extracts of 10, 20, 30, 40 and […]

EFFECTS OF NATURAL GROWTH HORMONES ON THE VEGETATIVE PROPAGATION OF Treculia africana A. Trecul.

Abstract Phytohormones have been found to be a reliable growth enhancer. This study therefore investigated the potentials of natural plant hormones on the rooting and survival ability of the species. The cuttings of T. africana were set in sixteen germination trays containing sterilized river with 3 replicates. The experiment had fifteen treatments and one control […]

EFFECT OF DEPTHS OF TILLAGE ON SELECTED MORPHOLOGICAL CHARACTERISTICS, YIELD AND YIELD COMPONENTS OF YELLOW MAIZE (Zea mays) HYBRIDS

Abstract Ploughing and sowing depths may not only be responsible for good emergence of seed but could also be responsible for stronger stalk and stem girth, it is therefore necessary to investigate effect of depths of tillage on some yield and yield components of yellow maize (Zea mays) hybrids. The land was divided into eighteen […]

HEAVY METAL POLLUTION FROM VEHICULAR EXHAUSTS ON NAPIER GRASS (Pennisetum purpureum) ALONG LAGOS-IBADAN EXPRESSWAY, SOUTHWEST, NIGERIA

Abstract This study evaluated heavy metal concentration on sampled plants (Pennisetum purpureum) resulting from exhausts fume pollution from vehicular movement along, the busiest inter-state route in Nigeria, the Lagos-Ibadan Expressway. At interval of 5 km from 7Up Bus Stop in Lagos to Ibadan Tollgate, samples of P. purpureum were collected at 5 m, 15 m […]

VARIABILITY AND TIME SERIES TREND ANALYSIS OF CLIMATE AND SMALL HOLDER FARMERS PERCEPTION: THE CASE OF JANAMORA WOREDA, NORTHWESTERN ETHIOPIA
