Selection of Technology Package for Higher Yield and Quality Seed Production of Carrot

Abstract

The study was conducted to evaluate variety and develop a package on quality seed yield of carrot. Two varieties viz., Brasilia Agroflora, Prima Agroflora and four different seed production packages viz., package T, package I, package II and package III were used. The two-factor experiment was laid out in RCBD with three replications. Varieties and different seed production packages showed significant influence on most of the parameter studied. Better seed yield (1153.31 kg/ha) and good quality seed (germination 86.91% and seed vigour index 12.62) were produced from Brasilia Agroflora. On the other hand, the lower seed yield (1042.88 kg/ha) and low quality seed (germination 81.41% and seed vigour index 11.89) were obtained from Prima Agroflora. The package I gave the highest seed yield (1425.07 kg/ha) and the best quality seed (germination 87.23% and seed vigour index 13.45), whereas the lowest yield (995.13 kg/ha) and the inferior quality (germination 79.25% and seed vigour index 10.67) were recorded from package T. In case of combined effect, the highest seed yield (1507.68 kg/ha) and the best quality seeds (germination 90.19% and seed vigour index 13.41) were obtained from Brasilia Agroflora with package I and the lowest yield (782.42 kg/ha) and low quality seeds (germination 76.89% and seed vigour index 10.12) were obtained from Prima Agroflora with package T combination. So, the variety Brasilia Agroflora with the package I (seed treated at 8ºC temperature, 25% root cut, treated with Dithane M-45, stecklings treatment at 120C, transplanting 1 December, spacing 20cm×25cm, N124P52K120S3.6Zn4B3Cu2Mo2 kg/ha fertilizers application; foliar spray of 150 ppm GA3) may practice for higher yield and better quality seed production of carrot.
