Abstract— Field experiment was conducted to study the impact of sulfur (S) and boron (B) on yield and yield component of broccoli. Sulfur was applied @ 0 (control), 20 and 40 kg ha-1 as elemental sulfur while B was applied at the rate 0, 1 and 1.5 kg ha-1 as borax along with a basal dose of N,P and K @ 120, 90 and 60 kg ha-1. All the fertilizers were applied at the time of sowing. The experimental design used was randomized complete block design (RCBD) with three replications. The data on plant height, number of leaves, flower diameter, head yield and biological mass were recorded along with S and B concentration in soil after crop harvesting. The result revealed that yield and yield parameter increased with increasing levels of S and B with higher head yield, flower diameter and plant height were observed when 40 kg ha-1 S and 1.5 kg ha-1 B were applied. It was further noted that head yield and head diameter were non-significant when averaged across the B treatment between 20 and 40 kg ha-1 applied S but significant from control. Similarly, when the yield parameters were average across the S treatment, there was a significant and linear increase with higher B level. Soil analysis showed that both B an S concentration in soil increased by increasing level of applied S and B. So the optimum level of S and B for broccoli was 40 and 1.5 kg ha-1respectively for higher yield of broccoli.
Keywords— Boron, broccoli, growth and yield, Sulfur.
