Effect of curd size on seed yield and quality of Cauliflower (Brasicaoleraceae var. botrytis L.)

摘要

A field experiment, to see the effect of curd size on seed quality and yield of cauliflower ( Brasica oleraceae var. botrytis L.) using cultivar ‘Hansa’ was conducted at vegetable experimental area, Institute of Horticultural Sciences, University of Agriculture, Faisalabad during 2016-2017. Five different head sizes were used as treatments comprising of T1 (Very small curd size 0-5 cm), T2 (small curd size 5-10 cm), T3 (medium curd size 10-15 cm), T4 (large curd size 15-20 cm), T5 (extra-large curd size 20-30 cm).Data for different seed yield and quality parameters was recorded and mean values were analyzed at a level of 5% probability. Maximum values for 1000 seed weight (3.82gm), Germination percentage (91.60%), Root length (5.78cm) ,Shoot length (8.32cm), Seedling length (14.10cm), Seedling fresh weight (0.45gm), Seedling dry weight (0.06gm) were recorded for T5 (extra-large curd size 20-30 cm).Electrical Conductivity of seeds (0.33 dsm) was recorded in case of T4 (large curd size 15-20 cm). Maximum values for Number of pods/Plant (408.80), Number of seeds per pod (12.60), Length of pod (6.48cm), Seed yield per plant (13.68gm), Seed yield (496.01 kg/ha-1) were recorded for T5 (extra-large curd size 20-30 cm). Significant difference between seed yield and quality of seed was noticed among varying size of curd of cauliflower. Extra-large and large curd size performed better than other treatments in terms of seed yield and quality of seed.
