Abstract/ Executive Summary:

An experiment was conducted at Horticultural farm of Sher-e-Bangla Agricultural University, Bangladesh for performance evaluation of twenty tomato cultivar coded from V₁-V₂₀ cultivated in summer. Maximum plant height (116 cm) and number of leaves (147) were found from cultivar Mini Anindyo Red (V₈) and Hybrid Tomato US440 (V₁₈) respectively. Maximum chlorophyll content, days to flower bud appearance and days to flowering were observed from cultivar BARI Tomato 6 (V₁₉); 53.0% chlorophyll, 40.3 days to bud appearance and 46.7 days for flowering. Maximum number of flower bud/bunch (6.0) and fruit/bunch (1.2) were observed from cultivar BARI Tomato 11(V₂₀) and Aran Chan Mini (V₁₂) respectively. Maximum number of branch/plant (5.7), number of bunch/plant (15.3), number of flower bud/plant (129.7), number of flower/plant (108.3), number of flower/bunch (6.7), number of fruit/plant (6.7), fruit length (22.8 cm), fruit diameter (61.3 mm), fruit weight (100 gm), yield/plant (667.1 gm), yield/plot (6.7 kg) and calculated yield/ha (22.3 ton) were found from cultivar Mini Chika (V₁₀). Thus, cultivar Mini Chika (V₁₀) was found to be suitable for cultivation in summer.

Start Date: 00-04-2013

End Date: 00-07-2013

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To evaluate the performance of twenty tomato cultivar coded from V₁-V₂₀ cultivated in summer seasons.

Methodology:

Location: Experiment was conducted at Horticultural Farm, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during April to July 2013. Site is situated in the subtropical climatic zone with wet summer and dry winter. Seed sowing: Seeds were sown on the seedbed in early March and seedlings were transplanted into the main field on early April. Varieties and experimental design: Twenty (20) cultivar of tomato, namely, V₁: SAU Red 1; V₂: MoMo Gold; V₃: MoMo Red; V₄: Purnima Regular Size; V₅: Fuji Regular Size; V₆: Urmila Regular Orange; V₇: Mini Amai; V₈: Mini Anindyo Red; V₉: Mini Anindyo gold; V₁₀: Mini Chika; V₁₁: Calory Passion Mini; V₁₂: Aran Chan Mini; V₁₃: Sunshine mini; V₁₄: Red Lantern; V₁₅: Bipul, V₁₆: Jholok, V₁₇: Nidhi, V₁₈: Hybrid Tomato US440, V₁₉: BARI Tomato 6 and V₂₀: BARI Tomato 11 were used in this experiment following a Completely Randomized Block Design (RCBD) with three (3) replication.Spacing, plot size and others: 40 cm x 60 cm spacing was maintained. Each of the plot size was 3.0 m ×1.0 m and 30 cm was left for irrigation and drainage between two beds. Thirty days old seedlings were transplanted in plots under transparent polyethylene shed tunnel. Fertilization: Manures and fertilizers were applied as recommended by Bangladesh Agricultural Research Institute. The entire amount of organic manure, TSP, Gypsum, Borax and half of the MP were applied during final land preparation. The remaining half of MP and entire urea applied in two equal installments, 1st at 15 days after planting and 2nd at flowering. Disease and insect control: Tomato leaf curl virus and tomato mosaic virus was found on few plants and these are controlled by spraying Dithane M45 and finally by uprooting. Insects were controlled by using Malathion 57 EC (2 times at 25 and 32 days after transplanting (DAT). Application of plant growth regulator: GA₃ was sprayed @ 20-ppm at 30 DAT for better plant growth. Data collection: Data were collected on number of leaves, plant height, chlorophyll content, number of branch/plant, days to flower bud appearance, days to flowering, number of bunch/plant, number of flower bud/plant, number of flower bud/bunch, number of flower/plant, number of flower/bunch, number of fruit/plant, number of fruit/bunch, fruit length, fruit diameter, fruit weight, yield/plant, yield/plot and calculated yield/ha. SPAD-502 Chlorophyll Meter was used for measuring chlorophyll content. Collected data were statistically analyzed using MSTAT-C computer package program and mean was calculated. Statistical analysis: Differences between treatments were evaluated by Least Significance Difference (LSD) test at 5% level of significance. To determine the genetic affinity of studied varieties and to group them, cluster analysis was performed using the squared Euclidean and Nearest Neighbour Method using SPSS (Statistical Package for the Social Sciences).

Achievement/Findings:

Tomato cultivars that were cultivated in summer season during this experiment showed significant variation for different growth and yield attributes. Best cultivar that produced maximum yield having potential growth and yield contributing characters was Mini Chika (V₁₀) followed by Mini Anindyo Red (V₈) and Mini Amai (V₇); these three cultivars may be recommended for multi-location trials of summer tomato production.
