Agricultural intensification has resulted in severe soil nutrient depletion in Africa.  Alternative agricultural practices have been promoted to restore and sustain soil fertility. Use of mineral fertilizer alongside different cropping systems has been particularly promising. This study was conducted in the Guinea savannah zone of Ghana during the 2015 and 2016 cropping season (July to November) to assess the performance of soybean and maize in a rotation system. In season one, using randomized complete block design the treatments were, soybean (without treatment), inoculated soybean, soybean with phosphorus application, inoculated soybean with phosphorus application and maize. During the second season, the first season experimental plots served as main-plots and divided into four sub-plots on which maize planted and treated with four nitrogen rates in a split plot design. The results show that soybean production leads to significant increase in residual soil nitrogen content of about 16kg/ha to 55kg/ha, which is about 28 folds higher than that observed in maize fields. The level of Residual N was enhanced with inoculation. Phosphorus application during the first season of maize cultivation led to increases in residual P levels, which had a positive impact on yield of soybean in the second season. Grain yield of maize that followed soybean in a rotation system performed better than maize that followed maize at various fertilizer rates. This shows that, the residual N and P helps maize and soybean respectively in a rotation system which makes it highly economical.

Rice is a staple food for Malaysian. Malaysian paddy farmers contributed up to 70% of the country’s needs. However, climate change impact to the agriculture activities. The aim of this study is to forecast the paddy production for four years in Kedah, Malaysia. Naïve forecasting method was used in this study. The forecasted results for the paddy production values from 2013 to 2016 are considered in this study. The finding shows that the decrease of paddy production in the year of 2013 but the paddy production increased from year 2014 until 2016. Overall, this research work forecasted gradual increments for the projection of four years rice’s production in Kedah.

The study was conducted in Amhara region Maksegnit town north Gondar Ethiopia with the objective of investigating honey bee products marketing practice; opportunities and constraints. The data was collected from 40 households from four PAs by using pretested semi structure questionnaire. The collected data revealed that the major products of honey bee are honey (67.5%) and the rest (32.5%) colony itself. The major reason of keeping bees in the study area is for income source. The value obtained by ranking index revealed that middlemen, tej (a mead or honey wine) houses and retailer are the three major honey buyers with the index values of 0.30, 0.24 and 0.21, respectively. The price of honey is majorly governed by quality and color of the honey with index values of 0.4 and 0.3, respectively. The highest and the lowest price of honey in the study area was found to be 133.50 ± 6.222 and 69.25 ± 12.483 Ethiopian birr (ETB) for white and black honey, respectively. Lack of road, lack of materials for measuring the quantity of honey and the variation in the color of the honey were found to be the three major constraints of honey marketing with the index value of 0.16 of 0.143 and 0.141, respectively. The major challenge for marketing of bee colony is unavailability of organized marketing place. The Increment in number of unemployed youth, increment in price of honey and colony and the high demand of honey and colony in the area are the three major opportunities available to be engaged in beekeeping sector in the study area. To alleviate challenges of bee product and colony marketing, the government should provide important inputs and awareness should be created for the farmers.

Objectives of the Study: The study examined the profitability of catfish production in Enugu –East L.G.A of Enugu state.

Sample Size and Sampling Procedure: A purposive sampling technique was employed in the selection of 50 respondents used for the study.

Method of Data Collection: Data for the study were collected using structured questionnaires and interview schedules.

Method of Data Analysis: Descriptive statistics, gross-margin analysis and profitability ratios were used in analyzing the data.

Results and Discussion: The result of the analysis showed that majority of the fish farmers (70%) were males and within the age range of 31 - 50 years. The result equally revealed that majority of the farmers (86%) had at least a National Diploma with about 5 -14 years fish farming experience. The result further indicated that cost of feed and fingerlings were the major cost component involved in catfish production. The gross margin analysis and profitability ratios revealed that catfish production is very profitable in the study area with a net income of about N576, 667 and a BCR of 1.6. The study however revealed that the high cost of farm inputs and poor credit facilities were the major constraints to catfish production in the area.

Recommendations: It was recommended that more fish feed producers be encouraged into the business to reduce the high cost of feed.

The survey was conducted to identify key challenges encountered by households in Makurdi metropolis of Benue state, Nigeria who are engaged in urban agriculture. A well structured questionnaire was used to collect data from a sample of 100 respondents used for the study. Data were analyzed using frequency, percentage and mean score. Results show that a greater percentage (46.0%) of the respondents engaged in cultivation of leafy vegetable, 22.0% cultivated cassava, 21.0% planted sweet potato, 18.0% cultivated tomato while 56.0% reared poultry, 23.0% kept goat, among others. Sources of agricultural information indicated by the respondents were family members/relations (85.0%), friends/neighbors (73.0%), radio (68.0%), extension agents (57.0%), etc. Major challenges encountered by the respondents in urban agriculture include inadequate size of farm land (M= 2.72), lack of access to credit facilities (M= 2.63), lack of funds (M= 2.50), high cost of labor (M= 2.49), insecurity of lands (M= 2.46), theft of crops at maturity (M= 2.38), lack of farm inputs such as improved varieties of seeds, fertilizer (M= 2.23), destruction of crops by stray farm animals (M= 1.96), among others. The study recommends that there is need for adequate provision of farm inputs by government at all levels at subsidized rate in order to reduce the cost of production and enhance optimum productivity.
