The experiment was conducted at the University of Port Harcourt Teaching and Research farm, Port Harcourt, Rivers State, Nigeria from April to August, 2019 on the effects of organic and inorganic fertilizers on the growth and yield of cucumber ( Cucumis sativus L). The research was done in a randomized complete block design with four treatments and replicated four times. The treatments include control (no application), NPK 15:15:15, spent mushroom substrate, and poultry manure. Data collected were, vine length (plant height), number of leaves, stem girth, leaf area, length of pod, weight of pod. Results showed that plots with poultry manure had significant effect on vine length, number of leaves, leaf area at 6 weeks after planting (WAP) and 8WAP. The highest number of fruits was 9.0 per plot or 15,000 per hectare and highest fruit weight was 1.59kg/plot (2,650kg/ha) which were higher than NPK 15:15:15 (0.47kg/plot or 783.33kg/ha) and spent mushroom substrate (0.19kg/plot or 316.67kg/ha). Hence, the use of poultry manure as organic source for the cultivation of cucumber in the study area would be recommended.

The study analyzed the marketing efficiency of groundnut in Nasarawa State, Nigeria. Primary data were collected using well-structured questionnaire. A multi-stage sampling procedure involving stratified, purposive and simple random sampling was used to select 174 groundnut marketers. Descriptive statistics was used to analyze the data. The results of the study showed that the respondents were in their active productive age with average of 42 years having 9 years of marketing experience years. Annual income of the marketers was 35.5% ranging between N100000-300,000 with majority (72.4%) having no access to credit while 55.2% were members of cooperatives. Results of the Gini coefficient (0.74) indicated that there were many sellers and buyers who had free entry and exit in and out of the groundnut marketing business which indicated a tilt towards a pure competitive market structure. The gross margin was 2016.62 per 100kg of groundnut marketed in the study area. This shows that the respondents made a profit of 2016.61 from every 100kg of groundnut sold, implying that groundnut marketing is a profitable business in Nasarawa State, However, further studies on the activities of middlemen on the marketing efficiency should be evaluated .

The study was conducted in 2016 and 2017 cropping seasons at the research farm of Akwa Ibom State University, Obio Akpa, Nigeria to examine the effects of nutrient management, vine cutting time and variety on growth, yield and quality of sweetpotato. The experiment was laid out as split-split plot in a randomized complete block design with three replications. Results revealed that a combination of 2.5t/ha poultry manure + 200kg/ha NPK fertilizer or poultry manure alone significantly increased vine length, number of branches/plant, shoot dry matter and fresh shoot biomass compared to application of 400kg/ha inorganic NPK fertilizer alone and the no fertilizer application. The highest storage root yield and carotenoid content were obtained from combined application of 2.5t/ha poultry manure + 200kg/ha NPK fertilizer. A mixture of manure and fertilizer also significantly reduced decay of storage roots. No vine cutting significantly increased fresh shoot biomass but reduced carotenoid content compared to cutting at 16 or 17 WAP, while date of cutting had no effect on storage root yield. Sweetpotato variety white – fleshed TIS 87/0087 had significantly higher fresh shoot biomass and storage root yield than orange – fleshed Umuspo 3 but carotenoid content was higher in the latter than the former.

Fresh tomato fruits have a very limited shelf life partly due to their high moisture content and respiration rate. A possible way of storing tomato fruits is to dry and process them into powder or paste. Therefore, this research was conducted to determine the effects of drying methods and packaging materials on physical and sensory qualities of powdered tomato in Yola, Adamawa State, Nigeria. Harvested fruits of tomato variety, “Rio de grande” were subjected to blanching and subsequent drying methods and packaging materials. The experiment was laid out in a Completely Randomized Design (CRD); with the drying methods placed in main plot while the packaging materials in sub-plot and repeated three times before storage for twelve weeks. At four weeks of storage, oven drying method was found to be statistically different (p≤0.05) in terms of water absorption capacity value of 3.19 (mg/100g). The glass jars performed better than polythene bags in color retention, taste and consistency at four weeks of storage. The study shows that tomato fruits can be successfully dried using oven, sun and shade drying methods but preferably oven drying method. The processed powder could be successfully stored for 12 weeks or above using either glass jars or plastic container without affecting the consumer appeal and this will also reduce the postharvest losses of tomato fruits.

SAMARICA is the second district of Occidental Mindoro province in the Philippines having a vast land area for rice production. It supports the rice milling sector of the province with promising facilities for postharvest of rice. This study investigates the rice farmers’ adoption level of integrated crop management practices (ICMPs). The adoption ICMPs aims to promotes farm productivity and efficiency. A total of 404 rice farmers participated in this study selected through a multi-stage sampling technique. Quantitative data were generated from the survey questionnaire and were analyzed using Descriptive Statistics. Partial Least Square Structural Equation Modeling (PLS-SEM) was used to analyze the relationship between production and postharvest practices. The results revealed that rice farmers have “very high” adoption of rice production technologies except for water technologies and intermittent irrigation with “high” adoption level. In terms of postharvest, there is “very high” adoption of mechanized harvesting and recommended moisture content for rice but “moderate” adoption for rice parboiler, dying machines, and threshing of rice right after harvest. On the other hand, a statistically significant evidence was found for production technologies as predictor of postharvest technologies, specific for the care and management of rice (β =0.55; P<0.01).

Soaking and fermentation are two food technologies that are used by households or agro-industrial establishments. These practices aim at improving food nutritional acceptability and sensorial parameters. Tacca leontopetaloides tuber was used to study alleviation of antinutrients by solubilization and leaching through soaking, or by enzymatic degradation through fermentation. Soaking has lasted 72 hrs, and fermentation 48 hrs. Chemical methods have been used to determinate antinutrient levels in processed and unprocessed T. leontopetaloides tubers slices. A statistical analysis by means of XLSTAT was purchased for principal components and correlations between variables. Results show that the major antinutrients have exhibited resistance to microbial enzymes during fermentation or to solubilization in water. Levels of most antinutrients have increased instead of lowering when tacca tuber slices were soaked or fermented. The increase of components during soaking and fermentation is linked to the decrease of soluble components in T. leontopetaloides slices. Phytate is an antinutrient which resists to both food technologies, and saponins can be leached by 43.4 % through soaking or by 50.7 % during fermentation. These powerful antinutrients in T. leontopetaloides tuber necessitate food technologies combinations to eliminate them. Further investigations are necessary to succeed in antinutrient levels alleviation in T. leontopetaloides tuber.
