Physicochemical Changes of Apple (Malus domestica) as Influenced by Maturity Stages and Postharvest Management Practices

Article in Press

This research was conducted to establish changes of physicochemical properties of three apple cultivars grown in Chencha (Ethiopia) as influenced by stage of maturity and types of packaging on a storage period of 3 weeks. All the measured physicochemical parameters (TSS, firmness, titratable acidity, pH, weight loss) significantly varied with the cultivars, maturity stage at harvest, packaging types, and weight losses....

Evaluation of Locally Available Botanicals Powder for the Management of Maize Weevil (Sitophilus zeamais) in Storage

Article in Press

Maize is the second most widely grown cereal and gaining importance as highly nutritious crop in Ethiopia. However, evidences showed that maize is severely damaged by storage insects, mainly Sitophilus sp. and need further research to minimize losses due to this pest in storage. In line with this, research was initiated to evaluate the efficacy of three botanical plants powders against S. zeamais under laboratory...

Evaluation of Morphometric and Physiological Seed Quality Traits of Improved Cowpea (Vigna unguiculata L. Walp) Varieties in Sierra Leone

Article in Press

A study was conducted at the Seed Laboratory of the Njala Agricultural Research Centre (NARC) to evaluate the seed quality traits of five cowpea genotypes at room temperature (25 ± 2 oC). The five genotypes studied were Slipeas 1, 2, 4, 5 and local Tabe. The trial was laid out in a Completely Randomized Design (CRD) in four replicates. The results indicated that the local variety (Tabe) had the highest percentage of seed...

Determinant of Rice Postharvest Losses at the Farm Level in Fogera District of the Amhara Region, Ethiopia

Article in Press

Rice is a crop that contributes to food security and farm income in Fogera district. Despite its contribution, there is a considerable loss in rice production at the farm level. Reducing losses at the farm level are important policy objectives to optimally design interventions targeted at reducing losses. Thus, this study assessed the extent of postharvest loss in rice at different stages at the farm level and factors...

Sesame Production and its Post-harvest Loss: The Case of Large-scale Producers in Kafta Humera District, Western Zone of Tigray, Ethiopia

Article in Press

This study analyzed post-harvest loss of sesame the case of large-scale producers in Kafta Humera district of Western Zone, Tigray region, Ethiopia. It was specifically aimed to address the research gaps by measuring post-harvest loss and analyzing its determinants of sesame produced by large-scale producers. For addressing these objectives the study used primary and secondary data obtained from field survey and desk...

Activities of Dioscorea sansibarensis powders in anti-oviposition and reduction of Bruchus chinensis emergence on Phaseolus vulgaris (L.)

Article in Press

Phytochemical screening and effectiveness of Dioscorea sansibarensis (Zanzibar yam) leaves, bulbils and yams powders were assessed as protectants of beans (Phaseolus vulgaris L.) against Bruchus chinensis beetle. 0.5 g of leaves powder on 50g of beans (0.99 w/w %) inhibited oviposition by 35.42% and yams powder reduced adult emergence from Ph. vulgaris by 37.03%. Bulbils powder showed less performance in all the bioassay...

Influence of Processing and Substrate Variety on Survival and Development of Tribolium confusum (Coleoptera: Tenebrionidae)

Article in Press

Confused flour beetle, Tribolium confusum is a major pest of grains and grain products. Some legumes hitherto not used as major food are gaining interest due to increase in human population and the need of food and feeds. Susceptibility of fresh and processed Glycine max and Cajanus cajan flours, and white wheat flour (control) to T. confusum was studied towards planning effective storage techniques, and developing cheap...

Development of composite protective coatings from chitosan, Aloe vera gel, and Jatropha oil as a plasticizer on the post-harvest qualities of orange fruit during Ambient Storage

Article in Press

Chitosan and some natural plant extracts were tested to maintain post harvest quality of orange fruits. Edible coatings based on chitosan (CH), Aloe veragel (AL), Jatropha Oil (JO), its combination with Aloe veragel (CHAL) and Aloe veragel with Jatropha Oil (JO) (CHALJO), were developed and applied on orange fruits, in order to improve its quality and shelf life during ambient storage. Weight loss, changes in soluble...

Drying characteristics and antioxidant properties of Java plum seed and skin waste

Article in Press

Java plum seeds and skin wastes recovered after passing fruits through a pulper were separated manually and dried in tray/fluidised bed drier at 50, 70 and 90˚C or in freeze drier at -55°C at 4.4 torr. Drying behaviour of java plum seeds and skin followed falling rate period and described adequately by Page's model. Drying rate constant was higher for fluidized bed drier varying from 0.00163 to 0.255406 h-1 for seeds and...

Efficacy of integration of three management tactics relative to unitary tactics against Maize weevil, Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) of stored maize in Ethiopia

Article in Press

Five and ten percentage rates of leaf powder of Calpurnia aurea (Ait.) Benth and Millettia ferruginea (Hochst) Baker as well as red and white local inert dusts each and their integration with resistance varieties of maize were evaluated as protectant against Sitophlus zeamais under laboratory condition. All treatments of the tested management tactics induced significantly (p < 0.05) higher adult mortality of weevils (8.33...

Does lining with leaves of Triclisia dictyophylla affect the proximate and phytochemical contents of stored Cola nitida?

Article in Press

Kola nuts (Cola nitida [Vent.] Schott and Endl.) are relevant to trade, and sustains livelihood as food, source of income, stimulatory and medical potentials. The phytochemical content is useful in several industrial processes. The duration and methods of storage may affect the phytochemical content of C. nitida. This study investigated the phytochemical effects of lining kola nuts with leaves of Moonseed (Triclisia...

Farmers traditional practices for pre and post-harvest pest control in crop production

Article in Press

Indigenous technical knowledge involves practices evolved by the farmers on their own experiences, which are passed from generation to generation. Indiscriminate use of chemical fertilizers, pesticides and fungicides in present day agriculture had lead to deposition of toxic residues in the food materials. However due to awareness on the health food products interest was turned towards indigenous technological practices...
