ABSTRACT

A field experiment was carried out at Rampur, Chitwan in split-plot design to study the effect of priming of carrot seed on germination, early emergence, field emergence, plant stand establishment and root yield and quality. The treatments consisted of two commercial varieties of carrot (New Kuroda and Nantes Fancy) as main plot and seven levels of seed priming as sub-plots with 3 replications. The treatment imposed seeds for the field experiment were also used for laboratory test with four replications. New Kuroda exhibited higher vigor index (637.2), faster early emergence (8.33 days), highest field emergence (56.33%) and plant stand (66.67%), thickest cortex diameter (1.70 cm) and higher economic yield of 22.13 t ha-1 (50.65% more than control) in 24 hrs. seed soaking in tap water than in non-primed seeds where as Nantes Fancy showed faster early emergence (8.66 days), highest field emergence (55.33%), higher plant stand (69.33%) and higher yield of 17.69 t ha-1 (9.94% more than control) in 12 hrs. seed soaking in 400C warm water.
