The study examined participation of farmers in homestead fish production and its implications for poverty alleviation in Bayelsa and Delta States, Nigeria. Primary data were sourced from one hundred and ninety two (192) respondents, spread across eight local government areas in Bayelsa and Delta States. Data from respondents were analyzed using percentages and means. Multiple regression was used to analyze the hypotheses of the study. Results showed that most (64.6%) of the farmers were part-time fish farmers, majority of the farmers (34.4%) primary occupation was civil service jobs and the mean number of years of being fish farmers was 12 years, indicating that they are experienced in the business. It was also revealed that the mean fish farm output and income was 164.60kg and ₦167,200 ($1,045) respectively. Result as well showed that security personnel should be employed by the farmers to curb the menace of theft, there is a need for the government through special programmes to ensure a good availability of inputs like fingerlings, fish feeds at affordable prices and the home stead fish farmers need to be trained on integrated pest and disease management method as this will help reduce the losses of the farm.

Zinc (Zn) deficiency is widely spread in Egyptian paddy soils and has negative impact on national rice (Oryza sativa L.) production. Field experiments were conducted at the research farm of the Rice Research and Training Center, Sakha, Egypt, to evaluate the effects of different methods of Zn application on rice growth, yield of Sakha 104 and nutrients dynamics in soil and plant. The experiment included four treatments: no Zn, root soaking, foliar and soil application. The results indicated that Zn application by different methods, significantly increased number of tillers, panicles, plant height, 1000-grain weight; filled grains% and grains yield of Sakha 104. Among the different of Zn application, soil application of 15 kg ha-1 as ZnSO4.H2O caused highest increase in total N percentage, total K percentage and available Zn content in both grain and straw, however, the percentage of total P decreased significantly. Zinc content in soil after harvesting was significantly affected by Zn application. Different methods of Zn tend to increase the total N and total K contents of soil but decreased P concentration significantly.

The study was conducted in Itu Local Government Area of Akwa Ibom State, Nigeria between July, 2014 and December, 2014 to assess resource poor vegetable farmers’ willingness to pay for a premium of organic fertilizer. With the aid of questionnaire, primary data were obtained from 60 vegetable farmers using multi-stage sampling procedure. Data were subjected to analysis using the univariate probit regression model. Results of analysis showed that whereas age of the farmer was significant (P<0.01) and positively related to willingness of farmers to pay for organic fertilizers; education, farm size, farm income were significant (P<0.01) and positively related to willingness of farmers to pay for organic fertilizer. Findings further revealed that marital status was positively significant (P<0.05). Increasing farm holdings and improvement in educational opportunities are policy decisions aimed at enhancing the willingness of resource poor vegetable farmers to pay for organic fertilizer as an alternative soil ameliorant.

Impact of Mariculture on the Macrobenthic Invertebrate Abundance and Distribution in Lagos Lagoon Nigeria

This study investigated the effect of a mariculture fish cage culture on the abundance, composition and distribution of macrobenthic invertebrates of Lagos lagoon from February 2011 through July 2011. A record of three animal Phyla – Mollusca, Arthropoda and Annelida was established with a total of 1469 macrobenthic taxa. The dominant species throughout the study were of the class Bivalvia - Aloidis trigona while the rarest species was the Polychaeta - Nereis succinea. - There was significant difference in the genera diversity (ANOVA test; p< 0.05). Generally, the diversity of macrobenthic invertebrate at the cageless site of the study area may have been influenced by the absence of fish cage because the highest fauna abundance was observed while the least diversity was at the cage downstream of the cageless site. Comparison of particle size showed a significant correlation between the three stations (p<0.01), at 99% mutual relationship between the three stations. Studies on the use of macrobenthic invertebrates to investigate the environmental impacts of anthropogenic activities such as fish cage culture system on the lagoon should include ecological impact to identify possible alteration in environmental conditions of benthic macro-invertebrates.

Influence of Heavy Metal Toxicity on Plant Growth, Metabolism and Its Alleviation by Phytoremediation - A Promising Technology

Heavy metals (HMs) contamination of soil and water is a serious problem in recent time and cause hazardous effects on humans and animals which ultimately results in destruction of environment. HMs such as Cd, Cr, Pb, As, Co, Cu, Ni, Zn, Mn, etc. are considered as environmental pollutants due to their toxic effects. These metals alter the plant growth, physiology, and development, it involves the production of reactive oxygen species (ROS) which leads to subsequent cell death, eventually results in the reduction of crop growth and yield. To sustain the agricultural environment, it is necessary to alleviate the toxicity of HMs from the environment. There are number of technologies evolved but, phytoremediation is an emerging technology that uses plants to clean up pollutants from the environment. It is a promising technology for the remediation of contaminated soil because of its low cost, non-intrusiveness, and sustainable features. Hyperaccumulator plants absorb, accumulate and decontaminate high concentration of metals in their above-ground tissues from natural contaminated sites such as mining, smelting, compost, sewage sludge, wastewater, and flyash producing areas.
