Four levels of boron (0, 0.65, 1.3, and 1.95kg B ha-1) and four levels of phosphorous (0, 30, 60, and 90kg P2O5 ha-1) were applied to study the effect of boron and phosphorous on yield, quality and elemental B and P uptake of cauliflower in the soils of Paklihawa, Rupandehi, Nepal. The highest curd yield, quality, B and P uptake by plant and available B and P in soils were obtained with the application of 1.3 kg B ha-1 and 60 kg P2O5 ha-1. B deficiency caused hollowness of stem, browning and bitterness of curd and was reduced significantly by using 1.3kg B (11.8kg borax) ha-1. This information is useful for cauliflower growers of Rupandehi area to increase the economic return from the cultivated land by improving quality and production of cauliflower. The information would be helpful for farmers and researchers of other areas besides research area.
