Abstract/ Executive Summary:

The experiment was conducted at the plastic house of Olericulture division of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during the 2015-2016 The growing season are T₁=Oct.-Jan., T₂=Feb.-May and T₃=Jun-Sept. In cucumber there is no significant difference in plant height among the planting time. Minimum day’s to1st female flowering inT₁ (52days).maximum in treatment.T₃(53). Days to 1^st harvest were earlier in T₂(61 days) treatment. No of fruit was higher in T₁ treatment (8). The maximum yield was obtained from T₁(1.8 kg) treatment and minimum in T ₃(1.3 kg). Tomato minimum days to 50% flowering inT₃ (64.3 cm) maximum in treatment. T₁(78.0cm). Days to 1^st harvest were earlier in T₂ treatment (73days). No fruit was higher in T₂ (25.0) treatment and lower in T₃ (21.0). The maximum yield was obtained from T₂(2.8 kg) and minimum in T₃(1.7 kg) respectively. Bitter gourd plant heights were higher in T₃ treatment (481.25cm). Cucumber produced a higher yield in treatment T₁ (Oct-Jan), while tomato and bitter gourd produced higher yield in T₂ (Feb-May) due to higher contributing characters

Start Date: 00-00-2015

End Date: 00-06-2016

Program Area: Crop-Soil-Water Management

Commodity: Vegetables

Objectives:

To determine the availability of tomato, cucumber and bitter gourd round the year.

Methodology:

The experiment was carried out at the plastic house of Olericulture Division, Horticulture Research Centre, BARI, Joydebpur, Gazipur, during December 2015 to June 2016. The study was set up in RCBD design. The cucumber variety alavi, BARI Tomato 14 and bitter gourd Tia variety are used as variety. In the year three crop season consider T₁=Oct-Jan, T₂=Feb-May, T₃= Jun-Sept. The seedlings were grown in a sponge block. Plants were grown on a steel tray containing cucumber nutrient solution. The trays were connected with a tank through a plastic pipe. Nutrient solutions were circulated within the trays 8 hours/day by an electrical pump. The water and nutrient solution “A” and “B” were added at the ratio of 1 :100, i.e, per 100-liter water contain 1-liter solution of each (Solution A and B ). The seedlings were grown in a sponge block. The sponge was cut into 2.5 cm cube size, in the middle of the cube the seeds were sown after that foam was placed in a tray (60x80x25 cm) containing 30L fresh water. A newspaper was placed over the Styrofoam to control the evaporation of water. After germination, the newspaper was removed. At two to three true leaf stages 10 to 20 cc nutrient solutions were added at an interval of 2 to 3 days. After 3 to 4 weeks the seedlings were transplanted in each planting time with proper spacing.
