Abstract/ Executive Summary:

An experiment was conducted at the RARS, Rahmatpur, Barisal and FSRD site, Lebukhali, Patuakhali during rabi 2001-02 and 2002-03 to find out the potential tomato variety for late rabi season. Four tomato varieties (BARI Tomato-4, BARI Tomato-5, BARI Tomato-6 & BARI Tomato-10) were planted in five different sowing dates (1 December, 16 December, 1 & 16 January and 1 February). BARI Tomato-4 planted at 16 December performed better and showed that late planting is feasible with reasonable good yield (61.67 t/ha) in 2001-02 but December 1 showed higher yield from BARI Tomato-5 in 2002-03. At Lebukhali, reasonable good yield was obtained from variety BARI Tomato-6 and BARI Tomato-2 which could be grown from Dec. 2 to Jan. 16.

Keywords: Tomato, Late planting

Location: Rahmatpur, Barisal and Lebukhali, Patuakhali

Start Date: 01-12-2001

End Date: 15-03-2003

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To find out the suitable tomato variety for late Rabi.

Methodology:

An experiment was conducted at the RARS, Rahmatpur, Barisal and Lebukhali, Patuakhali during Rabi season 2001-02 & 2002-03. The trial was set up in a split plot design with 3 replications. Five planting dates (1 December, 16 December, 1 & 16 January and 1 February) were assigned in the main plots and four tomato varieties (BARI Tomato-5, BARI Tomato-6 and BARI Tomato-10) were assigned in the sub plots. Unit plot size was 3x4 m² and the seedlings were transplanted following 60 cm x 50 cm spacing. Recommended fertilizer dose and cultural practices were followed as and when necessary. Diethene M-45 and Ridomil were sprayed before flowering. Collected data were analyzed statistically.

Achievement/Findings:

Rahmatpur, Barisal Among five different planting dates, 1 December planting performed better in all respect and gave the highest yield (40.20 t/ha). It is remarkable that plant height, fruit bearing, fruit size, fruit weight as well as Total Soluble Sugar (TSS) decreased with increasing temperature that is planting after December. Among four tomato varieties, BARI Tomato-5 gave the highest yield (23.09 t/ha) followed by BART Tomato-4. Significantly bigger fruit diameter and weight of fruit were produced from BARI tomato-6. Plant height, fruit size, weight and percent TSS (2.46) were higher in BARI Tomato-6 but bearing was less (7.83 fruit/plant). BARI Tomato-4 and BARI Tomato-5 showed higher bearing habit (25.97 and 21.35 fruits/plant). On an average, the highest yield was recorded from BARI Tomato-4. Significantly the highest plant height was obtained from D1V3. The treatment D1V2 showed significantly the highest fruits/plant. Fruit length revealed higher from treatments D1V4. Weight of fruit/plant varied from 29 to 94 gm but insignificant. All the varieties sown on December 1 with BARI Tomato-6 showed higher TSS (%). The highest fruit yield was recorded from December 1 sowing of BARI Tomato-5 variety. All the varieties showed lower fruit weight after January 16 sowing. On an average, higher fruit yield was obtained from December sowing (1 t/ha) with BARI Tomato-4 or 6. Lebukhali, Patuakhali Sowing date influenced significantly only plant height and fruits/cluster similar in the case of variety. Days to flowering, no. of fruits/plant, fruit wt., yield/plant and yield (t/ha) was significantly influenced by sowing date and variety. Sowing from Dec. 2 with variety BARI Tomato-6 and BARI Tomato-2 showed higher no. of fruits/plant. Similar trend was followed in case of fruits wt. On an average, the highest yield was obtained from BARI Tomato-2, BARI Tomato-6 in December 2 sowing.
