On Farm

Maize (Zea mays L.) is the most important cereal crop in Kenya with 90% of the total population relying on it as the main staple food. Post-harvest loss in maize is caused by insect pests such Sitophilus zeamais and Larger grain borer and the can sometimes be up to 90 percent. Synthetic chemicals are used to manage weevil infestation in maize. However, chemical residues have been detected on the stored maize prior to consumption. Additionally, continuous uses of synthetic chemicals have led to development of pest resistance reducing their effectiveness. This study therefore sought to evaluate a possible use of Ocimum kilimandscharicum essential oil to manage Sitophilus zeamais. The study also determined the effect of pretreating baglets with aqueous extracts of A. indica and W. ugandensis to enhance efficacy of O. kilimandscharicum oil. Laboratory experiments were carried out to establish insecticidal property of O. kilimandscharicum oil. Additionally, on farm experiments were carried out to establish the oil’s effectiveness and longevity. Maize grains were treated with O. kilimandscharicum oil in the first experiment and in the second treated maize grains were put in miniature synthetic bags treated with aqueous extracts of A. indica and W. ugandensis and stored in a granary for six months. On-farm experiment revealed that O. kilimandscharicum oil doses were effective against S. zeamais as compared with untreated maize grains. However, 10 ml per 1kg of maize grains was the best dosage. Weight loss in maize grains was proportional to the number of holed grains. Replenishment of the oil after the third month (at 6 ml, 8 ml and 10 ml) reduced significantly (p<0.0001) the number of holed grains as well as weight loss. Pretreatment of baglets containing maize grains with aqueous extracts of A. indica and W. ugandensis significantly improved protection of maize grains treated with O. kilimandscharicum oil. From the results of this study it can be concluded that plant extracts can offer a possible substitute to synthetic chemicals in post-harvest management of S. zeamais in stored maize. Use of essential oil of O. kilimandscharicum for post-harvest protection of maize grains against S. zeamais is therefore recommended

Zanthoxylum Armatum

Alternaria fruit rot is a major disease caused by Alternaria alternata (Fr.) Keissl., a prolific fungal pathogen. Among post-harvest diseases of tomato, fruit rot induced by A. alternata is the most damaging. Antifungal agents are widely used to control post-harvest management of tomato fruits. However, negative impacts of fungicidal residues in edible fruits and vegetables on human health cannot be over ruled. Eco-friendly ways of controlling Alternaria rot in tomato fruits offer a novel way of tomato rot management. The current study proposes an alternate method in controlling tomato fruit rots through Zanthoxylum armatum DC essential oil (EO) application. Gas chromatography-mass spectrometry profiling showed eucalyptol and sabinene as major components of Z. armatum EO. Furthermore, EO applied (0.5–4.5 μl/ml) showed significant inhibition of A. alternata growth (p &gt; 0.05) at 4.5 μl concentration tested. Lipid peroxidation assays revealed significant reduction in membrane damage in tomato fruits treated by EO compared to alone inoculated fruits with A. alternata. Elevated activities of superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase coupled with enhanced antioxidants such as ascorbic acid, glutathione, proline, and total phenols in EO-treated fruits may be linked with better fruit rot management than control fruits inoculated with A. alternata-induced rot alone. Mycelia and spore production was dramatically reduced in EO applied tomato fruits over A. alternata alone in tomato fruits (p &gt; 0.05). Interestingly, free radical scavenging activities of EO applied tomato fruits showed significant improvement compared to only pathogen-inoculated tomato fruits. Findings propose practical utility of Z. armatum EO as a plant-based antifungal for post-harvest management of Alternaria rot in tomato fruits.

Definition Of

The qualitative characteristics of mango fruits change throughout their development process and are also influenced by their duration. Harvesting at different times after the fruit set affects external and internal quality and the post-harvest behavior and management possibilities of the fruits. The objective of this study was to assess the evolution of the most important physicochemical and organoleptic parameters of cv. Osteen fruits concern the length of their stay on the plant and also to their post-harvest management. For this reason, fruits were harvested progressively in ten pickings. The study showed that mango fruits that are kept on the tree reach the best quality traits, corresponding to their physiological maturation. The length of the storage period needed to reach the consumption point varies greatly according to the harvesting moment and to the different environmental parameters, which also affect the organoleptic and physicochemical quality of the fruits. The number of days after full flowering were confirmed to be the primary information to consider when planning harvest with commercial use of the fruit, but interesting indications can be acquired through the definition of non-destructive (hardness, color) or destructive (dry matter) parameters. The data collected help improve mango fruit′s post-harvest management practices, to provide a product with constant quality and homogeneity to the consumer.

Gender Participation

The study was undertaken to examine the extent of women along with men participated in post-harvest activities; to identify the problems and constraints faced by them and find suitable solution from their perception. The post-harvest activities were estimated at farm level in Aman rice at Rangpur, Nilphamari, Khulna, Satkhira and Jessore district of Bangladesh by using survey data collected randomly from 270 rice growing households for the year 2012-13. It employed participatory approaches to investigate farmers’ perceptions on post-harvest management. The analyses shows women spends more time (591 hours ha-1) on PH activities than men (581 hours ha-1) but the ultimate decision maker of those activities are male indicating that women are very seldom given the opportunities to implement their ideas for execution although they are now gaining the right to give their opinion because of social awareness.J.
