Growth and Yield of Late Season Cauliflower (Brassica oleracea var. botrytis L.) Varieties in Mid-hill Region of Nepal.

Background: Cauliflower production during the late winter season has major problems including the requirement of long duration for its maturity, lower yield and poor postharvest quality, especially in the mid-hill region of Nepal. A field experiment was conducted to access the growth, crop maturity and yield of late-season cauliflower varieties at Puranchaur, Kaski in the mid-hill region of Nepal. Methods: The experiment was arranged in a randomized complete block design (RCBD) with toal eleven late-season cauliflower varieties in which nine were hybrid varieties viz. Freedom, Titan, Ravella, Artica, Bishop, Casper, Indam 9803, NS 106 and Snow Mystique while two were open pollinated varieties viz. Amazing and Snowball 16. The experiment was conducted from November 2016 to March 2017 with four replications. Result: Significantly shorter period for final curd initiation of 76 days was recorded in NS 106 and Indam 9803 which was statistically similar with Amazing. Significantly shorter period for final curd maturation of 90 days was recorded in Amazing which was statistically similar to Bishop and NS 106. Similarly, the highest curd yield of 50 mt/ha was produced by Bishop at 91 days after transplanting (DAT) while the lowest crud yield of 19 mt/ha was recorded in Snowball 16 at 113 DAT. Finally, it was concluded that Bishop found the best hybrid variety for higher curd yield and short duration for maturation while Amazing performed higher yield than Snowball 16 and early maturing variety in the mid-hill region of Nepal.
