Abstract/ Executive Summary:

Effects of 500, 1000, 2000, 3000, 4000 and 5000 ppm of cycocel on the 'Jaerla' variety of potato were studied at the Horticuiture Farm, Bangladesh Agricultural University during the winter season of: 1975-76. The plants treated with cycocel became dwarf and compact with shorter internodes. Maximum reduction in height and length of internodes were noticed in plants treated with 5000 ppm of cycoce. The length of largest leaf, the number of leaves in plants per hill, weight of tuber per hill, the number of tuber per hill and the yield were not affected significantly due to the application of cycocel,

Keywords: Cycocel, Vegetative growth,Tuberization, Yield, Potato

Location: Horticulture Farm, Bangladesh Agricultural University, Myrnensingh

Start Date: 18-11-1975

End Date: 18-02-1976

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

To observe the effect or cycocel on the growth and yield of potato .

Methodology:

The experiment was conducted at the Horticulture Farm, Bangladesh Agricultural University, Mymensingh during the period from November, 1975 to February, 1976. The variety of potato used in this study was 'Jaerla'. The whole tubers were used as seeds. The seeds of approximately 5,08 cm in diameter were sown on the 18th November, 1975 in furrows at a depth of 5.08 cm. The spacing of 60.96 cms from row to row and 20.32 cm from plant to plant was followed. The length and breadth of each plot were 365.76 cm and 243.84 cm, respectively. First earthing was done on 25th December, 1975 and it was followed by second one after another 15 days. Fertilizers were applied as per the recommendation of Ahmad (1). Cycocel was sprayed 3 times on the entire plant at an interval of 15 days, the first spray being on the 22nd day of sowing. The chemical was applied in seven different concentrations, namely 0, 500, 1000, 2000, 3000, 4000 and 5000 ppm. The experiment was laid out in Randomised Block Design. The data relating the height of the plants, the length of internodes, the length of largest leaf and number of leaves in plants per hill were recorded after 60 days of sowing. Harvesting was made on the 18th February, 1976 when the plants started to wither due to maturity.

Achievement/Findings:

The plants treated with cycocel became dwarf and compact with shorter internodes. Maximum reduction in height and length of internodes were noticed in plants treated with 5000 ppm of cycoce. The length of largest leaf, the number of leaves in plants per hill, weight of tuber per hill, the number of tuber per hill and the yield were not affected significantly due to the application of cycocel,
