Sorting In Bangladesh, sorting is practiced for most of the fruits and vegetables to remove damaged, diseased and insect infested produce on the basis of visual observation. However, in the advanced countries different types of sorters are used. The commonlyused sorting equipments are belt conveyor, push-bar conveyor and roller conveyor (Kitinoja and Kader 2003). 9.2 Washing Washing is a standard postharvest handling operation for many fruits and vegetables to remove adherences, dirt, latex and external pathogenic structures. Unfortunately, in Bangladesh fruits and vegetables are hardly washed before entering into the marketing channel, and this contributes to poor quality and considerable losses of the produce. Chlorination of wash water is very important in postharvest handling. Chlorine can reduce the spread of contamination form one item to another during the washing stage. The pH of the wash water should be maintained at 6.5 to 7.5 for best results. Typically 1 to 2 mL of chlorine bleach per liter of clean water provides 100 to 150 ppm total Cl (Kitinoja and Kader 2003). 9.3 Grading Grading is one of the important postharvest operations. In Bangladesh, grading is practiced in limited scale based on size, especially for mango, banana, pineapple, papaya and jackfruit. Otherwise, no grading standard is found available for most of the fruits and vegetables. In case of banana, the ‘Bepari’ prefers to purchase well-shaped and welldeveloped bananas. They usually purchase bananas on the basis of flatness of angularity of the fingers. They grade bananas based on bunch size into large, medium and small. Brinjal and cucumber are not properly graded by the growers. Regarding the grading of okra, the ‘Bepari’ prefers to purchase well-shaped okra pods. They rely on the visual/external quality parameters of okra pods like tenderness (by tip pinching), color, size and shape of the pods. However, tenderness is found to be the common means of judging the quality of the okra pods prior to taking decision on whether the produce to be purchased or not. There are no scientific methods of grading or grade standards of fruits and vegetables in Bangladesh. In this regard, the introduction of UREPGAP (common standards for agricultural farm management practices in the European countries) in the 1990s in Europe would be worth mentioning. Therefore, emphasis must be given to develop GAP (Good Agricultural Practices) for the horticultural produce in Bangladesh not only for export but also for domestic market development in order to ensure quality and safety in the horticultural supply chain. Sizing rings are used based on the size and shape of commodity to manually grade horticultural produce (FAO 1989). Automatic grading of fruits is also a common practice in the developed countries.

Insects Insects of different kinds are found to cause serious problems to okra crop. Fruit borer is found to be the major insect which causes severe damage to okra pods in Comilla. Higher doses of the insecticides are applied with shorter intervals to control insect pests by the growers. Diseases Diseases, namely yellow mosaic, rots and leaf curl are found to cause serious damage to okra crop. However, the most serious problem of okra cultivation is due to the infection by Yellow Mosaic Virus according to 96% of the growers of the surveyed Upazillas of Comilla. In Chandina Upazilla of Comilla, leaf curl (viral disease) is found to cause significant damage to okra crop. Control measures Most of the growers use chemicals for controlling insect and disease attacks. The commonly used insecticides and fungicides in the surveyed Upazillas are Dursban, Suntap, Sumithion and Carrate (insecticides), and Bavistin, Knowin Power, Indofil and Redomil (fungicides). Amongst the pesticides, Dursban, Bavistin and Knowin Powder are mostly used. The growers of the surveyed Upazillas are found to apply pesticides at the rates varied from 10-20 g/10-16 L of water (≈ 1-2 g/L water). The recommended doses of some important pesticides are: 2 mL/L (Dursban 20EC), 2.4 g/L (Suntap 50SP), 1 mL/L (Carrate 2.5 EC), 2.24 ml/L (Sumithion 50EC), 1 g/L (Bavistin 50WP), 2 g/L (Knowin 50WP) and 2 g/L (Redomil Gold) (Rahman 2008). The findings of the survey suggest that generally the growers use the recommended doses of pesticides except for the fact that the growers often use cocktail of pesticides with shorter interval to ensure total control of pests and diseases.In papaya, red mite and fruit fly are found to be the predominant insect pests in Pabna. Papaya mosaic and leaf curl are also found to be the most serious diseases in the papaya plantation in Ishurdi of Pabna, one of the leading papaya growing zones in Bangladesh. 3.7 Pest and diseases of orange Different types of bugs and beetles are found to cause damage to orange plants in Moulvibazar. Die back is observed to be the most serious disease in orange plantation in the Juri and Borolekha Upazillas of Moulvibazar. 3.8 Pest and diseases of brinjal Insects Insects of different kinds are found to cause serious problems to brinjal crop. The most serious insect of brinjal is shoot and fruit borer. To control insect damage, higher doses of insecticides with shorter intervals are very often practiced by the growers. Diseases In the case of brinjal, the major disease is wilt (64% in Raipura and 52% in Shibpur Upazillas of Norshingdi district). Control measures All the brinjal growers use pesticides to grow brinjal. The growers use insecticides and fungicides along with PGRs as cocktail.

The contribution of horticulture remains extremely important for ensuring food and nutritional security in Bangladesh. Horticultural crops in Bangladesh cover an area of 873 thousand hectares with a total production of 110 lakh metric tons (Monthly Statistical Bulletin 2009). The desired level of development in horticulture has not yet been achieved because of a number of constraints. Due to absence of proper postharvest management system, a bulk quantity of the harvested produce is damaged every year. More importantly, lack of proper storage and marketing facilities, and seasonal gluts force the farmers to sell their hard-earned produce at throw-away prices. The food and nutrition situation in Bangladesh is fragile due to inadequate and imbalanced diet intake. Consumption of a diversified diet to meet the needs of macro and micro nutrients needs to be promoted (Bhattacherjee et al. 2007; NFP 2008; BDHS 2009). Fruits and vegetables are highly valued in human diet mainly for vitamins and minerals. However, the present consumption of fruits and vegetables in Bangladesh is 126 g/day/capita (23 g leafy vegetables, 89 g non-leafy vegetables and 14 g fruit), which is far below the minimum average requirement of 400 g/day/capita (FAO/WHO 2003). However, according to HIES (2005), the consumption of fruits and vegetables including potato is 253 g/day/capita, which indicates a poor dietary status in Bangladesh. In this regard, the high levels of low birth weight (33%), underweight (41%), stunting (43%) and wasting (17%) among children less than five years; anemia among infants, young children, adolescent girls and pregnant women; and poor diet diversification are of particular concerns (BDHS 2009; BCIP 2010). The prevalence of overweight (12.5%) among women that has increased by 10% between 2004 and 2007 also indicate the existence of double burden of malnutrition in Bangladesh (BDHS 2009). A large proportion of Bangladeshi population is food insecure due to poor diet quality. The usual diet is heavily dependent on rice, and most of the energy in the diet is contributed by cereals. Rice accounts for 68% of the total calorie consumption in the year 2005. Therefore, even though rice is not a good source of protein, it constitutes about half of total protein consumption in the diet. High prevalence of micronutrient deficiency i.e. hidden hunger is common in the society, and the situation could be improved significantly by increasing the consumption of high quality and micronutrient-rich foods like fruits and vegetables. Due to tropical and subtropical climates, a variety of fruits and vegetables are grown in Bangladesh. Unfortunately, a considerable proportion of the harvested produce never reaches the consumers mainly because of postharvest losses. The estimated postharvest losses of fruits and vegetables lie in the range of 20-40% (Wills et al. 2004). Hence, there is general support among scientists for the proposition that ]]>

However, the present consumption of fruits and vegetables in Bangladesh is 126 g/day/capita (23 g leafy vegetables, 89 g non-leafy vegetables and 14 g fruit), which is far below the minimum average requirement of 400 g/day/capita (FAO/WHO 2003). However, according to HIES (2005), the consumption of fruits and vegetables including potato is 253 g/day/capita, which indicates a poor dietary status in Bangladesh. In this regard, the high levels of low birth weight (33%), underweight (41%), stunting (43%) and wasting (17%) among children less than five years; anemia among infants, young children, adolescent girls and pregnant women; and poor diet diversification are of particular concerns (BDHS 2009; BCIP 2010). The prevalence of overweight (12.5%) among women that has increased by 10% between 2004 and 2007 also indicate the existence of double burden of malnutrition in Bangladesh (BDHS 2009). A large proportion of Bangladeshi population is food insecure due to poor diet quality. The usual diet is heavily dependent on rice, and most of the energy in the diet is contributed by cereals. Rice accounts for 68% of the total calorie consumption in the year 2005. Therefore, even though rice is not a good source of protein, it constitutes about half of total protein consumption in the diet. High prevalence of micronutrient deficiency i.e. hidden hunger is common in the society, and the situation could be improved significantly by increasing the consumption of high quality and micronutrient-rich foods like fruits and vegetables. Due to tropical and subtropical climates, a variety of fruits and vegetables are grown in Bangladesh. Unfortunately, a considerable proportion of the harvested produce never reaches the consumers mainly because of postharvest losses. The estimated postharvest losses of fruits and vegetables lie in the range of 20-40% (Wills et al. 2004).

Horticultural crops in Bangladesh cover an area of 873 thousand hectares with a total production of 110 lakh metric tons (Monthly Statistical Bulletin 2009). The desired level of development in horticulture has not yet been achieved because of a number of constraints. Due to absence of proper postharvest management system, a bulk quantity of the harvested produce is damaged every year. More importantly, lack of proper storage and marketing facilities, and seasonal gluts force the farmers to sell their hard-earned produce at throw-away prices.
