Effect of Sowing Date and Plant Geometry on Seed Yield of Early Cauliflower (Brassica oleracea var. botrytis L.) cv. Sabour Agrim

Present investigation was framed with four sowing date (25th July, 10th August, 26th August and 10th September) and four plant spacing (50 × 40 cm, 50 × 50 cm, 60 × 50 cm and 60 × 60 cm) having 16 treatment combinations. The experiment was laid out in Factorial Randomize Block Design and replicates thrice. The result of the present investigation indicates that the main effect of date of sowing and plant spacing as well as their interaction effect were found significant. The significantly highest plant height (63.93 cm), leaf area (97.00 cm2), polar diameter (10.3 cm) and equatorial diameter (21.20 cm) were recorded on 10th August and seedlings were transplanted at spacing of 60 × 60 cm. Significantly number of branches/plant, number of siliqua/plant, Number of seed/siliqua, seed yield/plant, seed yield (q/ha) and 1000 seed weight were obtained when sowing was done on 10th August and transplanted at spacing of 60 × 60 cm. Therefore, it may be concluded that combined effect of sowing date (10th August) and plant spacing (60 × 60 cm) was the most effective treatment combination for growth and seed yield in early cauliflower.
