Abstract/ Executive Summary:

The experiment was conducted at the experimental farm of Olericulture Division, Horticulture Research Centre, BARI during 2014-2015 with five tomato varieties and four lines to evaluate their performance at early and late winter. In early planting, all the varieties and lines showed identical in days to 50% flowering but in late planting, the line C-51 showed earliness.In respect of harvest duration no significant difference was shown in both the time. In early planting, BARI Tomato -14 produced the tallest plant (83.10cm) which was identical to C-11 (83.07cm) and in late winter, the line C 51 produced the tallest plant (64.33Cm) while BARI Tomato 3(52.17cm) and BARI Tomato 2 (33.93cm) produced the shortest plant. The line C- 51 (18.33) and C-11 (29.3) produced the highest number of fruit in early and late winter respectively, while the line WP-7 produced the highest identical yield (18.77 and 29.7) in both the time. Minimum numbers of fruits (11.70 and 13.80) were produced from BARI Hybrid Tomato -3 and BARI Tomato2 in early and late winter respectively. BARI Hybrid Tomato 8 produced the heaviest fruit (82.20 g) which was identical with BARI Tomato 14(77.0 g)in early winter andin late winter BARI Tomato 15 produced the heaviest fruit (47.0 g. Fruit length and breadth were significantly varied in both the time and ranged were 3.43- 6.30 cm and 3.83-6.10 cm in early winter and , 3.10- 6.13 cm and 3.53-6.36 cm in late winter respectively. The highest fruit yield per plant was recorded from WP- 7 (1.21kg), followed by BARI Hybrid Tomato 8 (1.08 kg) in early winter but in late winter BARI Tomato 15 (1.12kg), followed by BARI Hybrid Tomato 8 (0.94kg) showed the highest per plant fruit yield, the lowest yield (0.55kg and 0.54kg) was recorded from C11 and C71 in both the time. Calculated the highest per hectare yield were recorded from WP-7 (41.20t/ha) followed by BARI Hybrid Tomato 8 (36.97t/ha), in early winter and BARI Tomato 15 (37.98t) followed by BARI Hybrid Tomato 8 (31.94t) and C-11(31.27t) were recorded in late winter. The lowest yield (18.87t/ha and 18.30t/ha) were recorded from C11 and BARI Tomato 2 in early and late winter. Total soluble solid (TSS) (%) ranges were 3.1-5.1 and 3.00-5.30 were observed in early and late winter respectively. So, it may be recommended that for bigger size and yield potentiality, BARI Hybrid Tomato 8 is suitable for both the time. Besides this, the line WP-7 is suitable for early planting for good number of fruit and higher yield and BARI Tomato 15 is suitable for late planting for bigger size fruit and higher yield.

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To find out the suitable lines/variety for early and late winter.

Methodology:

The experiment was conducted at the experimental field of Olericulture Division, HRC, BARI, Gazipur during the season of 2014-2015 to evaluate their performance at early and late winter. For early winter seeds were sown in the seed bed on 03 September, 2014 and seedlings were transplanted in the main field on 29 September, 2014. For late winter seeds were sown in seed bed on 15 January, 2015 and seedlings were transplanted in the main field on 10 February, 2015. The experiment was laid out in RCB design with three replications. The unit plot size was 4.0 x 1.0 m accommodating 20 plants in each plot having 60 x 40 cm plant spacing. The crop was fertilized with cowdung-N-P-K-S-Zn-B @ 10 ton-253-90-125-22-5-2Kg/ ha, respectively. Half of the quantity of cowdung, entire P, half of the K, entire amount of S and B were applied during land preparation. The remaining half of cow dung was applied during pit preparation. The rest of K and entire N were applied in three equal installments at 15, 30 and 45 days after transplanting. Irrigation, pruning, mulching, weeding and other intercultural operations were done as and when necessary. Data were recorded for some yield and yield contributing characters. The compiled data were subjected to statistical analysis for interpretation of results.

Achievement/Findings:

From two years results it may be recommended that BARI Hybrid Tomato-8 is suitable for both the time for its bigger size and higher yield. Besides this, the line WP-7 is suitable for early planting for good number of fruit and higher yield and BARI Tomato-15 is suitable for late planting for bigger size fruit and higher yield.
