Abstract:

Twelve cauliflower genotypes were evaluated against four sowing dates viz, October 1st, October 15th, November 1st, November 15th at Kerala. Analysis of variance revealed significant difference among sowing dates, genotypes and their interactions for all the characters studied. Among the sowing dates, November 1st sowing recorded highest curd and yield characters. Better plant height, leaves per plant, gross plant weight and leaf size were also exhibited by November 1st sowing. Among the varieties, NS 60N was the highest yielder based on yield characters. Curd depth, curd diameter and curd size index were also highest for NS 60N followed by G 45. Earliest among the varieties was Himshort followed by NS 60N. The interaction effects were significant for all the characters studied. Yield characters were best for NS 60N sown on November 1st. Best curd characters were exhibited by November 1st sowing of NS 60N. The study identified two high yielding hybrids namely NS 60N and G 45 as promising and November 1st sowing as the best sowing time for cultivation in the plains of Kerala.
