Studies on Indigenous Bacillus Thuringiensis Isolates active against Selected Insect Pests

Abstract: The overall goal was to contribute to crop-productivity by developing sustainable pest management and the objective was to select and identify an efficacious local B. thuringiensis isolate active against the selected stem borers, C. partellus, E.saccharina, B. fusca and S. calamistis.Various isolates of B. thuringiensis were isolated from soils and dead insects collected from different places in Kenya. They were screened against various stem borers including C. partellus, E. saccha...

The Prevalence of Trypanosoma Congolense Savannah in Shimba Hills, Kenya and Development of a Genotyping Protocol

Abstract: Eleven species/subspecies belonging to the genus Trypanosoma, cause African Animal Trypanosomiasis (AAT) with Trypanosoma vivax and Trypanosoma congolense being the predominant pathogens. Annually, AAT leads to losses worth 4.5 billion dollars to livestock dependent economies in Sub-Saharan Africa. In order to manage the disease, trypanocidal drugs have been in use. However, parasites resistant to these trypanocides have emerged making the treatment of AAT difficult. Parasite resis...

The complimentary role of wild habitats in crop pollination: a case study on the eggplant (solatium melongena l., solanaceae)

Abstract: In this study, carried out in Nguruman, southwestern Kenya, 10 bee species were identified as eggplant pollinators. Their foraging behaviour was shown to be affected by the prevailing ambient temperature and not time of the day or the number of flowers per square meter in the eggplant fields. Only 2 bee species, Xylocopa caffra and Narnia sp., visited the eggplant blossoms at a great frequency. Their pollinator effectiveness was determined in two eggplant cultivars (the Black Beaut...

Breaking Seed Dormancy In Bambara Nut (Vigna Subterranea (L) Verdc)

ABSTRACT   A study was carried out to investigate the effects of sulphuric acid, hot water and soaking of seed in water treatments on the germination of Bambara nut (V. subterranea) seeds were planted in poly pots for germination. 40 seeds of Vigna subterranea (one per poly pot) with ten replicates each were used. The highest germination was recorded in seeds soaked in water for 24 hours. Germination was observed to be low or slow in untreated (control) seeds. While there was poor or no resp...

Soil Amendment Using Poultry Manure on the Growth of Maize (Zea mays L) in Diesel Oil Contaminated Soil

ABSTRACT Experimental research on soil amendment using poultry manure on the growth of improved maize seeds (SUWAN-1-SR) in diesel oil-contaminated soil was carried out at the Research farm behind the Department of Botany, site II, Delta State University, Abraka. The experiment was laid out in Randomized Complete Block Design with four replicates. Rates of poultry manure applied were Og, 2g, 4g, 6g, 8g, and 10g. Data collected were plant height, stem girth, number of leaves, and leaf area. 

Some Aspects of Water Relations of two Mahogany Species

ABSTRACT The general distribution, growth form and economic importance of Kha%a senega!sir (Bear) A. Juss. and Khaya ivorensis A. Chev. are described. Some aspects of the water relations of seedlings of these two species, the former a savanna species and the latter a forest species were studied with the view of ascertaining whether moisture plays an important role in determining the pattern of their distribution. &rowth of seedlings under four soil watering regimes namely - -0.3 (A), -0,4 (B...

Comparative Bioconversion of Rice Lignocellulosic Waste and Its Amendments by Two Oyster Mushrooms (Pleurotus Species) And The Use of the Spent Mushroom Compost as Bio-Fertilizer for The Cult

ABSTRACT Oyster mushrooms (Pleurotus species) have been an important food item in both developed and developing countries serving an invaluable resource for nutrition, health and disease prevention. Although several agricultural wastes lignocellulose have been used for cultivation of oyster mushrooms worldwide and in Ghana, the most utilized is the wawa (Triplochiton scleroxylon) sawdust and its amendments for the cultivation of Pleurotus ostreatus in Ghana. However, a longer period of 28 da...

Ethnobotanical Study on Wealth of Homegardens in Gosiling Gewog of Tsirang District

Aim: To document the medicinal uses of homegarden plants by local healers. Study Design: Semi-structured interview was conducted with the prior approval from the gewog official. Five local healers were contacted for interview before field visits based on their popularity and experience of using medicinal plants in their locality. Place and Duration of Study: The study was conducted at Gosiling gewog, Tsirang District, Bhutan between May and June 2016. The homegarden and agricultural pract...

MODELLING OF HEAVY METAL BIOACCUMULATION OF Eichhornia crassipes [MART.] SOLMS AND Pistia stratiotes L. IN OLOGE LAGOON, LAGOS, NIGERIA

ABSTRACT Macrophytes such as Eichhornia crassipes and Pistia stratiotes are known bioaccumulators found in the Ologe Lagoon which receives effluents mainly from Agbara Industrial Estate.  However, the mechanism of heavy metal bioaccumulation by these macrophytes has not been fully understood. This study was designed to determine the mechanism of heavy metal bioaccumulation and model the phytoremediation capabilities of the macrophytes.  Five sampling stations: Owo (before the point of dis...

Ecological Utilization Of The Weed – Tithonia Diversifolia And Sustainability Of The Paper Industry In Nigeria

Abstract Tithonia diversifolia is found growing abundantly within the forest zone of Nigeria. The evaluation of the pulp and paper making properties of T. diverisifolia showed average fibre length, width, wall thickness and lumen of 827.66  186.40m, 20.29  3.92 m, 3.96  0.28 m and 12.16  3.96 m respectively.  This short fibre length and small wall thickness of T. diversifolia made it unsuitable for making strong papers.  However, it is good material for mak...

Evaluation Of Rhizobium And Mycorrhiza Interactions In Sustainable Maize(Zea Maysl.)And Soyabean(Glycine Maxl.) Production

ABSTRACT Maize and soyabean are among the staples in the world. Their sustainable production through the use of synthetic fertilizer causes soil degradation and ground water contamination. An alternative means of boosting and sustaining the production of these staples through the use of rhizobium and mycorrhiza have been reported but there are contradictory reports on interactions between the two organisms. Therefore, the objective of this study was to assess the influence ofRhizobium japoni...

A study ori some of the physiological and ultrastructural changes occurring on desiccation and rehydration of Myrothamnus fiabellifolia

ABSTRACT Some of the physiological and ultrastructural changes occurring during the dehydration and rehydration of the "resurrection" plant Myrothamnus flabellifolia were investigated. The changes in stem and leaf orientation through angles greater than 45 degrees were recorded, and these changes, along with the change in adaxial leaf surface pigmentation, may serve to limit bright-light and/or thermal damage to these plants. M flabellifolia retained more than 70% total chlorophyll content...

The Effect of Smoke Treatment on the Germination on Four Species of Mesembryanthemum :Some Preliminary Observations

Studies on the Ecology and Production of Seaweeds of Economic and Potential Economic Importance on the Namibian Coast.

ABSTRACT The seaweeds of the Namibian coast have received little attention from researchers despite the fact that there is a successful industry based on seaweed exploitation. Beach cast Graci/aria verrucosa (Hudson) Papenfuss is collected (9000-15000 t (wet) y-1) in the Luderitz area for the production of agar, Laminaria schinzii Foslie was harvested for a short period from April 1987 to March 1989 and there is an increasing interest in utilizing other seaweed species on the coast. The natu...
