Even if marketing of horticultural crops like tomato, onion and banana had been increased over the last few years, there are so many market related problems. The main objective of the study was to analyze the challenges and opportunities of marketing onion, tomato and banana at Logia town, Northeastern Ethiopia. The selection of the crops is mainly based on their relative economic importance and marketability. A number of respondents in logia town were interviewed. The analysis was made with the help of descriptive statistics. A total of 96 of which 48 consumer and 48 retailer respondents’ were drawn through purposive sampling technique at each level. The age of respondents ranged from 20-52 years with the average of 36 years. About 14.58% of the sample respondents were illiterate and 27.08% able to read and write. About 64.58 % of the respondents were married. The sur...

Research paper thumbnail of Effects of Different Level of Nitrogen Fertilizer Application on Growth, Yield, Quality and Storage Life of Onion (Allium cepa L.) at Jimma, South Western Ethiopia

Yield and productivity of the crop has been far below the regional and national standards owing to several factors; absence of location specific fertilizer recommendation being the major among others. In Ethiopia, post harvest loss of vegetables contributed up to 30% yield reduction. Thus, a field experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine Research field during dry season to study the effects of Nitrogen fertilizer application on growth, yield, quality and storage life of irrigated onion under Jimma condition, South Western Ethiopia. The treatments consisted of four levels of Nitrogen (0, 50, 100 and 150 kg N ha-1) that laid out in Randomized Complete Block Design with three replications. Data on growth, yield, bulb quality and storage life parameters were recorded and analyzed using GenStat 12.1 version computer soft ware packages. Results of the study revealed that; Nitrogen fertilizer applications had shown a highly significant effect on growth, yield and quality of onion. Similarly, the keeping qualities of the Onion bulbs are highly influenced by application of N at different levels. Excessive application of Nitrogen fertilizer caused higher bulb rots (%); bulb sprouts (%) and weight loss (%) during the three month storage time at ambient temperature. This can be recommended for use by potential onion investors or farmers in the study area.

The major factors that limit vegetable crops production are shortage of cultivars and agronomic practice, poor quality seed, poor irrigation systems, lack of information on soil fertility, diseases, high postharvest loss and poor marketing system. In smallholder farming system, the causes of nutrient deficiency include high plant nutrient uptake, removal of entire crop residues, use of cattle dung as source of fuel energy for cooking, nutrient loss through leaching, P-fixation in acid soil and gaseous loss of N. Of the three primary macro nutrients, plants require N in the largest amounts. N enhances rapid growth, increases leaf size and quality.

It is a gaseous plant hormone that is responsible for fruit ripening, growth inhibition, leaf abscission, aging and a wide range of other plant processes. It is color less gas that is naturally produced by plant and function as a plant growth regulator. In this way ethylene behaves in the same way as hormones in mammals. It triggers specific during plants natural growth and development such as ripening. Though this action it induces changes in certain plant organs such as Texture change, color change and tissue degradation some of this change may be desirable qualities associated with ripening; in other cases it can bring damage or premature decay. Harvesting of Fruits and Vegetables (i.e. Banana and Tomato) may be intentionally or unintentionally exposed to biological active levels of ethylene and both endogenous and exogenous source of ethylene contribute to its biological activity.

Other crops in this family are Onion ( A.cepa L.), Leek ( A. ameloprisum ), Shallot ( A. asacloncum L) and Chile ( A. schoenoprasum L). Garlic is the second most widely used of cultivated bulb crops after Onion. It is an erect annual herb that can reach a height of 75cm- 90cm and grows during dry and middle winter season (Brewster, 1994). Garlic is believed to have originated in central Asia (India, Afghanistan, West China, Russia, etc) and spread to other part of the world through trades and colonization (Purse glove, 1972 and Tindall, 1986). According to FAO (2001), production of garlic stood at about 10 million tones per annual which is only about 10% that of bulb onion. China is the largest producer followed by South Korea. The world average yield of garlic is about 10 per hector, but it can go up to 19 per hector. World garlic cultivation was increased from 771,000 ha of 1989/90 to 1,204, 711 ha of land in 2007 wi...

In these days of rapidly enlarging population in the developing countries of the world where food is already short, there is an increasing urgency to do a better job of conserving mankind food supply in order to alleviate hunger and malnutrition. Losses of fruit and vegetables are occurring from the field to the fork and even pre-harvest practices are strongly affects the magnitude of losses that occur at a later stage. Postharvest loss is the issue of food security in many developing countries like Ethiopia and it is the concerns of all people. Severe fruits and vegetables postharvest loss and quality deterioration mainly occurred during harvesting, marketing, transporting, processing and storage which leads to reduction in producers out puts, unavailability of food, malnutrition, effects on the economy of the people and the country. There is high magnitude of loss in fruits and vegetables crops as compared to other due to the nature of the crops. Many scientific studies were reported that numerous causes and the extent of the loss particularly, in fruits and vegetables. This might be because of financial, managerial and technical knowledge limitations in harvesting techniques, storage and cooling facilities in difficult climatic conditions, infrastructure, packaging and marketing systems. In order to minimize these problems, the appropriate agricultural techniques such as the general principles of extending shelf-life of these crops must be put in place. There should be proper management of temperature, humidity and effective methods for preventing these losses. Since most national governments acknowledge that postharvest food losses is complex, therefore, it requires a commitment to an integrated approach, involving numerous organizations, including local communities and groups. As a general, this can be used as a good indication as all concerned bodies should aim for development of effective and efficient policies and strategies to solve existing problems. So the main objective of this review is to find out the concepts and problems of post-harvest food losses in perishable crops.

Yield and productivity of the crop has been far below the regional and national standards owing to several factors; absence of location specific fertilizer recommendation being the major among others. In Ethiopia, post harvest loss of vegetables contributed up to 30% yield reduction on vegetables and fruits. Thus, a field experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine Research field in dry season to study the effects of Phosphorus (P) and Potassium (K) fertilizer on quality and storage life of irrigated onion under Jimma condition, South Western Ethiopia. The treatments consisted of factorial combinations of three levels of Phosphorus (0, 46, and 92kg P2O5 ha-1) and four levels of Potassium (0, 40, 80, and 120 kg K2O ha-1) laid out in Randomized complete Block Design with three replications. Data on yield, bulb quality and storage life parameters wer...
