Environmental management is critical to the survival of the ecosystem as well as ensuring environmental sustainability and productivity. This study investigated the factors affecting the adoption of environmental management systems (EMS) by crop and livestock farmers in Abia State of Nigeria. Multistage sampling technique was used in selecting the sample used for the study. Data collected using structured questionnaire and interview schedules were analyzed using descriptive statistics such as frequency tables, means, percentages, and ordinary least squares regression analysis. The result of data analysis revealed that there is relatively low rate of adoption of EMS by the farmers.

A two - year field experiment was conducted at the Teaching and Research Farm of the University of Ado - Ekiti, Nigeria, during 2004 and 2005 cropping seasons to evaluate the influence of tillage methods, position of minisetts on mother corm, and the interactions between these two treatments on the growth and yield parameters of cocoyam. The design was a split - plot configuration, laid out in a randomized complete block, with three replications. Minisett position on mother corm constituted the main-plot treatment, namely: head (top), middle and tail minisetts, while tillage methods i.e. conventional tillage (CT) and no – tillage (NT) were the sub-plot factors.

The effects of salting, fermentation, and frying on freshwater snails (Pila ovata) meat samples were studied. The proximate compositions of the processed and unprocessed samples were determined. Salting decreased protein and fat contents but increased ash, and dry matter. Fermentation significantly increased protein but decreased fat and carbohydrate. Frying increased the fat content as well as the dry matter. All processed samples were higher with protein (67.20% - 74.20%), dry matter (85.95% – 87.31%), ash content (1.18% - 2.51%) and fats (7.86% - 12.22%) compared to the unprocessed raw snail meat sample in which the values were protein (16.45%), dry matter (20.95%), ash content (0.72%), fat (1.83%).

Quality indices of discoloration and germination energy were evaluated in local white and yellow maize varieties obtained from different harvesting seasons in selected States of South Eastern Nigeria viz: Enugu, Anambra and Ebonyi and compared with approved international standards. Results showed that the grains from all the locations and harvesting seasons were of good quality rating 2 or (1 - 10% discoloration) and poor quality grains of rating 3 or (11-25% discolouration). The germination energy decreased with increase in storage time up to six months irrespective of the storage method used and also- in late maize harvests of October/November (70.9, - 73.0%) when compared to those harvested in the months of April/May and July/August 92. 4 - 93.8%).
