Abstract/ Executive Summary:

Effects of different concentrations of Cycocel on 'Oxheart' variety of tomato were studied at the Bangladesh Agricultural University Horticultural Farm during the winter season of 1972-73. The concentrations ranged from 0 to 2000 ppm. Cycocel treated plants were dwarf and compact with shorter internodes and with comparatively harder stem. Plant height was reduced by about 25% with 2000ppm Cycocel spray. Earlier flowering and fruiting were achieved by Cycocel treatment. Application of Cycocel in 2000ppm hastened the maturity of fruits by about 13 days. Percentage of fruit set was not affected with the use of Cycocel. Fruit size was reduced by the application of the chemical. There was no significant reduction in yield by treatments of Cycocel concentration upto 1250ppm though higher concentrations gave significant reduction.

Keywords: Cycocel, Plant size, Fruiting response, Tomato

Location: Horticultural Farm, Bangladesh Agricultural University

Start Date: 00-00-1972

End Date: 00-00-1973

Program Area: Variety and Species

Commodity: Tomato

Objectives:

To study the effects of cycocel on plant size and fruiting response of tomato

Methodology:

The experiment was conducted at the Horticultural Farm of the Bangladesh Agricultural University during the winter season of 1972-73. The seeds of the 'Oxheart' variety of tomato used in the study were the collections of the Horticultural Farm from the crop grown in the locality for several years. The seeds were sown on October 5, 1972 and the seedlings were transplanted in the main field on November 5, 1972. Cycocel was sprayed on the entire plants at an interval of 21 days, first spray being on 21st day of sowing. The chemical was applied in 7 different concentrations which were considered as the treatments of the experiment. The concentrations were 0, 500, 750, 1000, 1250, 1500 and 2000ppm. The experiment was laid out in complete randomized block design.

Achievement/Findings:

Plant height was reduced by about 25% with 2000ppm Cycocel spray. Earlier flowering and fruiting were achieved by Cycocel treatment.
