Abstract/ Executive Summary:

A field experiment was conducted at the experimental field of Horticulture Department, Sylhet Agricultural University, Sylhet, Bangladesh to find out the suitability of tomato production during summer season of May to October, 2014. Five tomato hybrids viz., BARI hybrid tomato-3, BARI hybrid tomato-4, NHC-1, NHC-2 and NHC-3 were evaluated for tomato production during summer season under Sylhet condition. Different parameters like number of fruits plant^-1, individual fruit weight, fruit length, fruit width, total soluble solids, fruit yield plant^-1, etc. were significantly differed among the tomato hybrids. Significant variation in respect to fruit yield was also observed among the hybrids. The highest number of fruits plant^-1 was counted from the BARI hybrid tomato-3 (25.30) followed by BARI hybrid tomato-4 (24.33). The heaviest individual fruit was observed for the NHC-2 (43.23g) while it was the lowest for BARI hybrid tomato-3 (35.70 g). The NHC-2 hybrid had the highest fruit length (4.50 cm) and fruit width (3.40 cm). Among the hybrids maximum 5.3% total soluble solid was observed in BARI hybrid tomato-3. The hybrid, BARI hybrid tomato-4 produced the highest fruit yield (0.97 kg plant^-1) followed by NHC-1 (0.91 kg plant^-1). Benefit cost ratio revealed that one can earn more than four thousand taka decimal-1by growing tomato during summer season in Sylhet region. This indicates that there is a bright scope of tomato production during summer in Sylhet region.

End Date: 00-10-2014

Program Area: Variety and Species

Commodity: Tomato

Objectives:

The present study was under taken to evaluate the performance of selected hybrid tomato under Sylhet condition.

Methodology:

The experiment was carried out at the experimental field of Horticulture Department, Sylhet Agricultural University, Sylhet, Bangladesh during May 2014 to October 2014. The climate of the experimental area is subtropical in nature from May 2014 to October 2014 which is characterized by high temperature, heavy rainfall, and high humidity. It belongs to the Khadimnagar soil series of Eastern Surma-Kushiara Floodplain under the Agro ecological Zone-20 (FAO, 1988). The pH of the soil was around 4.98, soil organic matter 1.79% and soil EC was 0.47 dS m^-1. The experiment was conducted with 3 hybrid tomato lines viz., NHC-1, NHC-2, NHC-3 and along with BARI hybrid tomato-3 and BARI hybrid tomato-4. Seeds of five tomato hybrids were sown in raised seed bed on 14 May 2014. Seedlings were transplanted in the main field on 10 June 2014. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. The unit plot size was 2.3 m × 2.4 m having 4 rows bed^-1 and 6 plants row-1and 24 plants bed^-1. Plants were spaced at 60 cm × 40 cm between row to row and plant to plant, respectively. The unit plots and blocks were separated by 50 cm and 75 cm, respectively. The land was acidic in nature hence, lime (Dolomite) was applied in the field @ 4 kg decimal^-1. Each plot was fertilized with well decomposed cowdung 15 ton, urea 300kg,TSP 200 kg and MoP 150 kg ha-1, respectively (Rashid and Singh, 2000). Half quantity of cowdung and the entire quantity of TSP were applied during final land preparation. The remaining cow dung and half of MoP were applied 5 days before planting. The whole of urea and remaining half of MoP were applied in 3 equal splits as top dressing at 15, 30 and 50 days after transplanting. The crop was protected from rain providing polythene tunnel. Irrigation, pruning, mulching, weeding and other intercultural operations were done as and when necessary. Data were recorded for yield and yield attributing characters and statistically analyzed using MSTAT software.

Achievement/Findings:

It is apparent from the above discussion that cultivation of summer tomato is suitable for Sylhet region and one can earn more than Tk 5000 decimal^-¹ which is appreciable. Therefore, the hybrid BARI hybrid tomato-4 and NHC-1 promising line can be taken for adaptive trials in the farmer’s field in Sylhet region. The major constraint is the initial cost for bed and polyethylene shed preparation. In order to overcome this constraint, it is necessary to provide credit with easy terms and conditions.
