Evaluation of Soil Fertility and Performance of Maize(Zea Mays L.)in Small Holders Maize Farms in Namtumbo District, Ruvuma Region.
Maize yield in Namtumbo district is low and ranges from 1-2 t/ha in most small holders farms as compared to 7-10 t/ha reported in other parts of Tanzania. The yield is below the crop potential productivity due to low use or not using fertilizers completely. The objectives of the study were to …

The calcinogenic principles of Trisetum flavescens
Studies have been conducted on the calcinogenic plant Trisetum flavescens in order to determine the physiological actions and chemical nature of the toxic substance or substances. An organic soluble substance was extracted and purified and shown to promote intestinal phosphate transport and …

An experimental and theoretical investigation of the migration of moisture in cocoa beans
This work is essentially an investigation of non-convective moisture movement as the result of a temperature gradient in hygroscopic porous materials, in particular, cocoa beans. The aim of the research has been to determine experimentally the bulk moisture diffusion coefficient for cocoa, and, by …

Studies on fungal biomass and activity associated with the decomposition of plant litter in freshwater
A clearing and staining method using 2 stains, with one acting as a counter-stain for fungi, gave higher estimates of fungal biomass than other staining methods and it correlated well with the agar film technique. Using the method, it was possible to examine the spatial distribution of hyphae on …

Phytochemical and biological investigation of erigeron annus (L.) Pers for antimicrobial activity and potential DNA gyrase inhibitors
Compositae plants of the genus Erigeron have ca. 390 species, widely distributed in in most temperate regions around the world. Erigeron annus (L.) Pers. (fleabane) is one of the most valuable plants in the genus, used in Chinese folk medicine to treat indigestion, malaria, enteritis, hepatitis and …

A comparative study of certain soil-borne cereal pathogens with reference to carbohydrate utilisation and polysaccharide hydrolysis
Cochliobolus sativus, Fusarium culmorum and Gaeumannomyces graminis var tritici isolates produced pectin degrading enzymes, xylanase and carboxymethylcellulase when grown in a salts medium with an appropriate carbon source. There was little difference in the amounts of enzymes produced by the …

Stereocontrolled synthesis of plant growth regulators Abscisic acid and Xanthoxin
The project is concerned with the total synthesis of plant growth regulators related to abscisic acid (ABA). The biological activity of these plant growth regulators, ABA and Xanthoxin, and their derivatives is influenced by the stereochemistry of the double bond system in the side chain, the …
