ABSTRACT


The study analysed post-harvest losses of fresh tomato marketing at various stages of the food supply chain viz. farm, wholesale and retail market levels in three Local Government Areas (LGAs) of Kano State namely; Kura, Tofa and Wudil. Multi-stage sampling technique was used for sample selection. A pretested questionnaire was used
to collect data from the respondents selected randomly. A proportion of 10% of actors was chosen from a sample frame of 1604. The sample size comprises 96 producers, 21 wholesalers and 43 retailers making a total of 160 respondents. The data collected were analysed using descriptive statistics and the Post-harvest loss estimation model. The results of the analysis revealed that the major causes of tomato post-harvest losses were physical fruit damage, pest and disease attack, and varietal
characteristics. The losses were greater during harvest for producers and greater during storage for the marketers. To reduce problems associated with post-harvest losses, the study recommends training farmers on post-harvest handling technologies, providing improved packaging, storage, and transportation facilities at affordable prices, harvesting produce at the proper maturity stage, and avoiding the avoidance of rough
handling of fruits to reduce physical damage. Keywords: Tomatoes, Post-harvest losses, Production, Marketing, Kano State,

ABSTRACT


This project work investigated and compared the strength of manual method of producing hollow sandcrete blocks with machine compaction method of producing hollow sandcrete blocks obtained from Omu-Aran, Kwara State, Nigeria. A total of sixty (60) was used for this project work. The block industries were visited and a total of Forty-eight (48) blocks were obtained, twelve (12) blocks for both 6” and 9” from four block industries and control sample of 1:7 mix design were produced, six (6) blocks each of 6” and 9”. The blocks were subjected to various tests such as dimension check, bulk density, water absorption and compressive strength. The average density in these industries and control sample were within the minimum bulk density of 1,500 kg/m3 specified by BS 2028 (BSI 1975). The water absorption rates for the block industries ranged between 8.826 to 13.363% compared to the average water absorption for the control sample which 10.1%. Only one block industry was able to meet the minimum requirement for water absorption, which is below 12%. The compressive strength for 6-inch blocks from the block industries ranged from 0.25-0.41N/mm2 and for 9-inch ranged from 0.3-0.49N/mm2 compared to
the compressive strength of control samples for 6-inch and 9-inch produced were 0.31N/mm2 and 0.39N/mm2 respectively, which are below required standards. It revealed that machine compacted blocks have a higher compressive strength than the manually compacted blocks, but all the samples of the sandcrete blocks were below the Nigeria Industrial standard (NIS 87:2000) specification.

ABSTRACT


The bitter kola, Garcina kola is an important plant distributed in West Africa and its efficacy in handling fish hatchery challenges have been tested and documented. This study was carried out to evaluate the effect of the G. kola on the hatchability of Clarias gariepinus broodfish and short-term survival of fry. C. gariepinus broodfish were exposed to the same concentration of bitter kola powder. After fertilization, products
were incubated in medium containing 1.0, 1.5, and 2g bitter kola seed extract. The control had no bitter kola seed extract. 2 weeks after hatching, the fry were fed with the commercial feed Coppens in which 0.00, 1.00, 1.5 and 2.0gms of bitter kola powder was incorporated for 56 days. The water quality parameters varied following increasing level of bitter kola seed extract but non-significant (p˃0.05). The ammonia level also followed the same trend approaching intolerable levels for fish production. Hatchability, growth and survival were significantly higher in the control
(p˂0.05) relative the treatments. The elevated levels of ammonia may be responsible for the difference between the control and the treatment. This study is useful to scientists, hatchery managers and fish growers and it emphasizes the need to optimize protocols and conditions for the utilization of phyto resources for improved husbandry practices.

Biosecurity for Agricultural Development: A Panacea for Preventing Aflatoxin from Predisposing Fish Feeds to Contaminants

ABSTRACT


Aflatoxins is a causal organisms that causes a disease known as Aflatoxicosis. They are chemicals produced by some species of naturally occurring fungi (Aspergillus flavus and Aspergillus parasiticus) commonly known as moulds. Aflatoxin are common contaminants of oilseeds crops such as cottonseed, peanut meal, corn, wheat, sunflower, soybean, fish meal and nutritionally complete feeds can also be contaminated with fungal organism. The four major aflatoxin (AFB1, AFB2, AFG1 and AFG2) are direct contaminants of grains and finished feeds. It attacks FEEDS when
stored in an environment with a temperature above 270C (800F), humidity levels greater than 62% and moisture levels in the feed above 14%. The researcher used fish feeds form 30 fish farmers inn Gboko Local Government Area of Benue State. Th feeds were subjected to Afla Check test kit in order to ascertain the presence of aflatoxin. Temperature were determined using thermometer and the weight, length were also measured. Statistical analysis was used in order to determine the significance
difference (p=0.05) at different levels of analysis.
