Abstract/ Executive Summary:

An experiment was carried out at the field laboratory of Horticulture Department, Sylhet Agricultural University during the winter season from October 2013 to March 2014 with a view to evaluate fruit and seed production potentiality of tomato genotypes. Eight tomato genotypes namely C-11, C-21, C41, C-51, C-71, FP-5,WP-10 and HT-025 were used for this study. The experiment was laid out in a Randomized Complete Block (RCB) Design with three replications. A remarkable variation was observed among the tomato genotypes at the seedling stage of hypocotyls color, stem length, root length and number of leaves at 1 st inflorescences of seedlings etc. The genotype C-41 produced the highest number of fruits (48.00 plant^-1) but its corresponding individual fruit weight was the lowest (34.33 g). The lowest number of fruits plant^-1 was harvested from the line WP-10 (22.33 plant^-1), and it had the highest individual fruit weight (66.67 g). Significant variation was observed in weight of fruit plant^-1. The highest fruit yield plant^-1 was recorded from the genotype HT-025 (2.02 kg plant^-1) and the lowest was recorded from the line FP-5 (1.17 kg plant^-1). Corresponding hectare^-1 fruit yield was the highest in HT-025 (68.68 tones) followed by the line C11 (68.0 tones). The highest number of seeds fruit^-1 was counted from the genotype C-51 (85.42) very closely followed by C-11 (81.67). The genotype C-41 produced the lowest number of seeds (49.28 fruit^-1) identical to that of C-21 (51.72). The genotype HT-025 had the highest 1000-seed weight (2.90 g) which was identical to that of C-41 (2.80 g). The lowest 1000-seed weight was recorded from WP-10 (2.20 g). Seed yield plant^-1 was varied from 3.64 g to 9.41 g. Among the genotypes, C-11 produced the maximum amount of seeds (319.94 kg ha^-1) and lowest seed production recorded from WP-10 (123.76 kg ha^-1).

Commodity: Tomato

Objectives:

The tomato genotypes C-11, C-21, C-41, C-51, C-71, FP-5, WP-10 and HT-025 were used to evaluate fruit and seed yield performances of different tomato genotypes during winter season under Eastern Surma Kushiyara Floodplain.

Methodology:

Description of the study area The experiment was conducted at the experimental field of Horticulture Department, Sylhet Agricultural University, Bangladesh during October 2013 to March 2014. The study area is located on latitude 24°54" to 33°67" N and longitude 91°54" to 95°88" E. The soil of experimental site belongs to the AEZ-20: Eastern Surma Kushiyara Floodplain. Soil is brown hill soil in texture and highly acidic (p H 4.83) in nature. The climate of the experimental site was subtropical characterized by heavy rainfall during May to October and scanty during rest of the year. The mean monthly relative humidity ranged from 46% to 80% with the peak occurring between July and August. Experimental Design and Planting Seeds of eight tomato inbred C-11, C-21, C-41, C-51, C-71, FP-5, WP-10 and HT-025 were sown in three different raised seedbed on October 10, 2013. After seed sowing the seedbed was given partial shade with black net. The seedbed was also covered by a fine white net (60 × 60 mesh) to protect seedlings from insect damage. Eight days old seedlings were transplanted in second seedbed at the spacing of 5 cm x 5 cm distance for hardening of the seedlings. Thirty days old seedlings were transplanted in the experimental field on 29 November, 2013. The experiment was laid out in a Randomized Complete Block (RCB) design with three replications. The unit plot size was 1.0 m × 4.8 m having double row bed^-1 , 12 plants row^-1 and 24 plants plot^-1. Plants were spaced at 60 cm × 40 cm between plant to plant and row to row, respectively. The unit plot and blocks were separated by 50 cm and 75 cm drains, respectively. The land was fertilized with 15 t well-decomposed cowdung, 300 kg Urea, 200 kg Triple super phosphate (TSP) and 150 kg Muriate of Potash (MoP) hectare^-1, respectively. Half of the cow dung and the entire amount of Triple super phosphate (TSP) were applied during land preparation. The remaining cowdung and half of MoP were applied before five days of planting. The whole of urea and half of MoP were applied in 3 equal splits as top dressing at 15, 30 and 50 days after transplanting. Stacking was provided to keep the plant erect. Weeding, irrigation, pruning, mulching, gap filling and other intercultural operations were done as and when necessary. Collection of data and statistical analysis Observations of different characters were recorded from each genotype. Data on the following parameters, in eight tomato genotypes were recorded on the basis of AVRDC-GRSU characterization record sheet. Data were recorded for yield and yield contributing characters and statistically analyzed using MSTAT software and the means were separated according to Duncan’s Multiple Range Test (DMRT).

Achievement/Findings:

Based upon the above results and discussion it was concluded that as highest fruit yield plant^-1 was found from HT025 (2.02 kg plant^-1), corresponding hectare^-1 fruit yield was 68.68 ton. The highest number of seeds fruit^-1 was counted from the genotype C-51 (85.42). The genotype C-41 produced the lowest number of seeds fruit (49.28). The genotype HT-025 had the highest 1000-seed weight (2.90 g) and C-11 (319.94 kg) produced the maximum amount of seed hectare^-1. The genotype HT-025 will be taken in further research to obtain the high yielding genotype.
