Effect of molybdenum and its application on seed production of cauliflower

抄録

The experiment was conducted at Regional Agricultural Research Station, Ishwardi, Pabna during rabi season of 2014-15 to find out the appropriate dose of Molybdenum for seed production of cauliflower (var. BARI Phulcopi-1). Five Mo doses (0 kg/ha, 0.5 kg/ha, 1.0 kg/ha, 1.5 kg/ha and 2.0 kg/ha) and three application method (100% basal, 50% basal + 50% foliar spray and 100% foliar spray) were used as treatment variables. Maximum number (16.33) of leaves/plant was found in 2 kg Mo/ha as basal application which was statistically similar to 1.5 kg Mo/ha (16.00) as basal application and minimum number (13.33) of leaves/plant was recorded from control. The highest seed yield (240.71 kg/ha) was obtained from 1.5 kg Mo/ha used as 50% basal + 50% foliar spray and the lower seed yield (122.76 kg/ha) was obtained from control. The highest gross return (Tk 2407100), gross margin (Tk2211525) and benefit-cost ratio (12.31) wererecorded from the same treatment.
