Standardization of Technology for High Quality Carrot Seed Production

Abstract/ Executive Summary:

The varietal experiment showed that Brasilia (Agroflora) gave the best seed yield than the rest three varieties viz. Prima (Agroflora), New Kuroda and TS Kuroda. The spacing experiment demonstrated the superiority of 25cmX25cm spacing for planting of stecklings over 30 cm X 30 cm, 30 cm X 25 cm and 25 cm X 20 cm. The extent of root cutting experiment revealed that 75-day old roots were better than 65 and 85-day old roots, and cutting of lower ½ part of root was better than the cutting of ¼ and the control (no root cut). The experiment on phosphorus and boron fertilization demonstrated that the application of 30 kg P and 0.6kg B/ha were optimal for the production of carrot seed. The experiment on the growing condition showed that the poly tunnel with shade providing net was better for quality seed production of carrot over the polythene as well as the open field conditions. The low temperature steckling treatment demonstrated that 8ºC showed better performance over the ambient and 4ºC temperature for 30 days. The umbel keeping experiment revealed that the primary and the secondary umbels gave the highest seed yield. From the findings of the seven previous experiments, three packages were selected on the basis of performance that are package-I (75-day old steckling, 50% root cut, 25 cm x 25 cm spacing, steckling vernalization at 8ºC, keeping primary and secondary umbels, application of 30kg P and 0.6kg B/ha and ploy tunnel with shade providing net growing condition); package-II (85-day old steckling, 25% root cut, 30 cm x 25 cm spacing, steckling vernalization at 4ºC, no umbel cut, application of 25 kg P and 0.4kg B/ha and ploy tunnel with white polythene growing condition); and package-III (65-day old steckling, no root cut, 25 cm x 20 cm spacing, steckling vernalization at ambient temperature, no umbel cut, no additional P and B fertilizer use, open field growing condition). Finally, the packages were tested on Brasilia (Agroflora) and New Kuroda carrot varieties which resulted in 898 and 868 kg/ha seed yield, respectively, package-I gave the best performance over the package-II, III as well as control method (no treatment were applied, only 75-day old roots were uprooted and planted in the bed at 30 cm × 25 cm spacing).

Keywords: Technology, Carrot Seed

Location: Mymensingh

Start Date: 00-08-2005

End Date: 00-08-2008

Program Area: Seed Technology

Commodity: Carrot

Objectives:

To find out the optimum age and spacing of steckling, extent of root cutting, steckling vernalization, growing conditions, doses of phosphorus and boron, umbel keeping for the high quality carrot seed production.

Methodology:

The present study comprised a series of eight experiments carried out in order to develop a package of technology for the production of high quality carrot seed. All the experiments were conducted at the USDA-Alliums Field Laboratory, Horticulture Farm, Bangladesh Agricultural University, Mymensingh during August 2005 to July 2008. The study was set to find out the optimum age and spacing of steckling, extent of root cutting, steckling vernalization, growing conditions, doses of phosphorus and boron, umbel keeping for the high quality carrot seed production.

Achievement/Findings:

A package of technology for high quality carrot seed production has been developed. A treatment combination of 75-day old steckling 50% root cut, 25 cm X 25 cm spacing, steckling vernalization at 80c, keeping primary and secondary umbels, application of 30 kg P and 0.6 kg B/ha and crops grown under ploy tunnel with shade providing net gave the highest yield and quality of carrot seed.
