ABSTRACT

Knol-khol (Brassica oleracea var. gongylodes L.) is a cool season crop belongs to the family Cruciferae and is originated from the coastal countries of Mediterranean region (Choudhary, 1967). Cruciferous vegetables are one of the dominant food crops worldwide. Cruciferous vegetables are vegetables of family Brassicaceae (also called cruciferae). They are good source of many health promoting and potentially protective phytochemicals including folic acid, phenolics, carotenoids, selenium, glucosinolates and vitamin c. A field experiment was carried out to investigate the effect of different manures and fertilizers on the growth and yield of knol-khol (Brassica oleracea varcc. gongylodes. The days taken to knob initiation showed highly significant positive correlation at genotypic and phenotypic levels with days taken to first harvest only, whereas knob diameter, knob length and dry weight of leaves showed negatively significant correlation with days taken to knob imitation at genotypic and phenotypic levels. The days taken to complete harvest showed positive correlation at genotypic and phenotypic levels with Knob diameter, knob length, fresh weight of knob, fresh weight of leaves and dry weight of knob. The Fresh weight of knob showed positive significant correlation at phenotypic and genotypic levels with fresh weight of leaves, whole plant weight and dry weight of leaves. Study concluded that the combination of organic manure and bio-fertilizer improved the growth and yield of knol-khol (Brassicaoleraceavar. gongylodes) plant. Therefore, theapplicationoforganic manure and bio-fertilizers are recommended for knol-khol production.
