Effect of Root and Shoot Cutting on the Seed Production of Three Varieties of Carrot

An investigation was carried out at the United States Department of agriculture (USDA) Allium Field Mymensingh, Bangladesh Agricultural University Horticulture Farm Laboratory during the period of January 2019 to May 2019 to supervise the effect of root and shoot cutting (steckling) on the seed generation of three different carrot kinds. Four different cutting viz 0%, 25%, 50% and 75% root and shoot cutting (steckling) treatments and three varieties of carrot viz. PA (Prima Agroflora), BA (Brasilia Agroflora) and Indian AC0075 (Germplasm PI 652410). Three replications and a Randomised Complete Block Design were used to set up the experiment. The different percent of cutting and varieties had momentous effect on growth and seed generation of carrot. Among the varieties Brasilia Agroflora developed the best performance in respect of seed generation (0.82 g/plant, 20.41 g/plot and 136.11 kg/ha) copied by Prima Agroflora (0.47 g/plant, 15.00 g/plot and 100.00 kg/ha) and the lowest seed yield (0.73 g/plant, 13.88 g/plot and 92.59 kg/Ha) was filed from the variety Indian AC0075. The treatments percent root and shoot cutting (steckling) had momentous effects on most of the parameters practised. 50% root and shoot cutting treatment significantly influenced the yield and yield subscribing roles and gave the greatest yield of seed (0.73 g/plant, 19.99 g/plot and 133.33 kg/ha) whereas, 0% root and shoot cutting treatment produced the least seed yield (0.64g/plant, 14.25 g/plot and 95.06 kg/ha). Stirring the combined effect of percent root and shoot cutting (steckling) and variety with the maximum output of seeds (0.74 g/plant, 27.77 g/plot and 185.18 kg/ha) was earned from the set of treatments used with the Brasilia Agroflora variety with 50% root and shoot cutting (steckling) and the least seed yield (0.28 g/plant, 9.44 g/plot and 62.96 kg/Ha) was noted from the fusion of diversity Prima Agroflora with 0% root and shoot cutting (steckling) treatment.
