Evaluation of Cauliflower Genotypes for Growth, Yield and Quality Traits under Foothill Condition of Nagaland

Background: A field experiment was conducted during the Rabi season of 2022-2023 and 2023-2024 at the experimental farm of the Department of Horticulture, School of Agricultural Sciences, Nagaland University, Medziphema Campus, to evaluate different genotypes of cauliflower for their growth, yield and quality under the foothill conditions of Chumukedima district, Nagaland. Methods: Twelve genotypes of cauliflower were evaluated in a randomized block design with three replications and the data were pooled over two years. The experimental material comprised twelve genotypes: G1, G2, G3, G4, G5, G6, G7, G8, G9, G10, G11 and G12. Result: The results revealed that genotype G11 exhibited maximum plant height (42.55 cm), plant spread (56.59 cm), curd diameter (12.96 cm), curd size (103.03 cm²), net curd weight (513.97 g), curd yield (139.99 Q ha-¹) and curd compactness (61.00). Genotype G4 recorded the highest stalk length (11.67 cm), while genotype G9 had the maximum number of leaves per plant (18.97). Genotype G5 showed the highest gross curd weight (707.33 g). The ascorbic acid content was highest in genotype G11 (20.14 mg/100 g). Based on the experimental findings, genotype G11 was proven to be a potential high yielder over other genotypes under the foothill conditions of Nagaland.
