Climate Variability, Incidences and Mitigation Strategies among Poultry Farmers in Abia State, Nigeria. International Journal of Sustainable Agricultural Research, 5(3): 38-45.

This paper investigated climate variability, incidences and mitigation strategies among poultry farmers in Abia State, Nigeria. It specifically analysed the trend of climate variables over the period of 30 years, the perception of poultry farmers as regards the impact of climate variability on poultry production in the study area, and examined the different mitigation strategies adopted by these farmers. A multi-stage sampling technique was employed in choosing the required sample of 120 poultry farmers. Data were collected with validated structured questionnaire, and analyzed using descriptive statistics. The result showed a high inter-annual variability in the volume of rainfall from 1983 to 2012 with insignificant correlation (0.0781) between rainfall volume and time. Also, the result showed reduction in number of rainy days and sunshine duration between 1983 and 2012 with correlation coefficients of 0.146 and 0.132respectively. Temperature had significant positive relationship with time with correlation coefficient 0.638.High mortality rate, disease outbreak, smallness of egg size, poor quality of egg shell, heat stress and reduced feed intake actually impacted on poultry production in the study area. Climate variability was therefore found to have affected poultry production in the study area and this has serious environmental and food policies implication. The respondents identified the use of climate resilient breeds, closeness to hatchery, feed improvement, mixed farming, use of artificial cooling system and stocking less during harsh season as major mitigation strategies to climate variability. It is therefore recommended that the government should come up with appropriate policy that will assist the poultry farmer to be more resilient and able to cope with effect of climate variability. Policies should also be formulated to reduce the emission and accumulation of green-house gases in our environment.
This study is one of very few studies which have investigated climate variability, incidences and mitigation strategies among poultry farmers in Nigeria. The paper’s primary contribution is finding that mortality rate, disease, egg size, quality of egg shell, heat stress and feed intake impacted on poultry production in Nigeria.
Effects of Different Storage Conditions on Rooting and Shooting Performance of Grapevine (Vitis Vinifera L.) Cuttings in Hydroponic Culture System

The shortfall in grapevine planting materials urged the researchers to enhance rapid propagation techniques with successfully storing the propagation materials such as rootstock and scion canes. The present study was conducted to assess the effects of different storage conditions (cold storage room at 1 °C plus 80-90% relative humidity and sand medium in open area) on rooting and shooting performance of cuttings of seven grapevine cultivars. For assessments, a hydroponic culture system was established in which the cuttings were rooted. Investigations on the cuttings prepared from the canes sampled at 6th, 7th and 8th months of the storage times showed that cold storage room significantly maintained the quality of canes with better callusing, rooting and shooting features. Storage at cold room can be recommended for long term storage, while dipping the canes in damp sand medium can be considered for a short time around a few months keeping of grapevine canes. Grapevine cultivars exhibited slight variation in response to both storage duration and storage conditions.
This research is one of very few studies which have investigated the healthy and practical maintenance of propagation materials by comparing the scientific storage room and indigenous farming strategy conditions.
