In a protected net house, we investigated the impact of five different types of vegetables on various maturation stages, including tomato, broccoli, sweet pepper, cucumber, and netted melon. Vegetables cultivated under protected conditions in a transparent poly-film net house can improve quality, maturity, fruit size, and yield. When fruits and vegetables are picked before they are fully mature, they may stay green for longer, but they may not ripen to a satisfactory color and flavor, resulting in a loss of consumer confidence. Furthermore, because fruit continues to grow until the harvest, immature fruit will be smaller than mature fruit, reducing harvest yield. We tried to determine the right maturation stages in order to avoid product loss during our investigation. The tomato was found to be an appropriate size (6.5 cm length and 6.2 cm diameter), weight (84 g), TSS (4.5 percent), pH (4.3), “turning red”, and “tasty” at the week 5 stage, while the broccoli was found to be an appropriate size (12.0 cm length and 13.0 cm diameter), weight (360 g), and “green” color at the week 5 stage. At the week 6 stage, the nettled melon was found to be of appropriate size (15.2 cm length and 14.5 cm diameter), weight (800 g), TSS (10.8 percent), pH (6.3), “net fully developed” on the fruit skin and “much tasty,” while cucumber was found to be of appropriate size (8.8 - 10.8 cm length and 2.2 - 2.9 cm diameter), weight (61 - 88 g), TSS (3.8 - 4.1 percent), pH (6.3), “less powdery”. As a result, establishing the optimal maturity of our research will benefit both consumers and growers.展开更多

Among the various insect and diseases of tomatoes, the late blight, TYLCV, bacterial wilt infection and leaf miner, fruit borer infestation are most common in Bangladesh. The TYLCV infection was observed 0% to 27% infection, while 47 entries showed zero percent infection. The range of bacterial wilt infection was 0% to 10% and zero percent infection was observed in 62 entries. In case of leaf miner infestation and fruit borer infestation, the range was 0% to 43% and 0% to 10%, respectively. Considering tolerance to late blight, TYLCV, bacterial wilt infection and leaf miner, fruit borer infestation, fruit size, fruit shape, plant growth nature, cluster nature of fruit, type of fruit ten entries AVTO 1010, AVTO 1706, AVTO 1713, AVTO 1829, AVTO 1909, AVTO 1911, AVTO 1915, AVTO 1921, AVTO 1954 and SLA 011 were found zero percent late blight, TYLCV, bacterial wilt infection and leaf miner, fruit borer infestation. So, these ten entries can be selected for disease and insect tolerant tomato varieties development as well as developing disease and insect tolerant hybrid tomato varieties.展开更多

This study included six vegetables 1) Tomato, 2) Eggplant, 3) Sweet pepper, 4) Broccoli, 5) Cucumber;6) Okra, as well as four nethouse treatments: 1) UV stabilized transparent polyethylene film with 60 mesh insect net along with green shade net (NH1);2) UV stabilized transparent polyethylene film with 60 mesh insect net (NH2);3) 60 mesh insect net (NH3);4) Open field infestation of white fly, aphid, leaf miners, mites, and ESFB was observed under open field conditions followed by NH1 conditions, while the lower infestation was observed in NH2 and NH3 for all vegetables. From the study, we found the use of stabilized transparent polyethylene film with a 60 mesh insect nethouse provided a negative effect on the presence of different types of notorious insects on vegetables. So, this type of protected nethouse will provide a new dimension to producing safe and quality vegetables in Bangladesh.展开更多

The days to first harvest were varied from 106 to 116 days while twelve lines were harvested within 106 - 108 days. The number of fruits per plant varied from 11.7 to 71.3, while the range of single fruit weight was 16.4 - 186.6 g. Fruit yield per hectare was 15.7 - 150.4 t/ha where the highest fruit yield per hectare was obtained from the lines AVTO 1702 (150.40 t/ha), followed by AVTO 1409 (126.54 t/ha), AVTO 1010 (120.60 t/ha), AVTO 1712 (111.33 t/ha), AVTO 1711 (107.23 t/ha). The range of fruit length was observed 2.07 to 6.8 cm, while the fruit diameter was 1.9 to 7.4 cm. The range of pericarp thickness was 0.14 to 0.8 cm, while the range of number of locule was 2.0 to 8.2. The range of TSS level was 2.0% - 8.2%, while the shelf life of the tomato lines was recorded 5.2 to 10.3 days. Considering earliness, quantitative and qualitative characters, eleven WorldVeg Center tomato lines AVTO 1010, AVTO 1315, AVTO 1409, AVTO 1711, AVTO 1712, AVTO 1713, AVTO 1717, AVTO 1907, AVTO 1911, AVTO 1915 and AVTO 1921 were found promising. So, these eleven lines can be selected for further confirmation.展开更多
