Total plant biomass was 106 gplant<sup>-1</sup> at 4.4 kg B ha<sup>-1</sup> compared to 79 g plant<sup>-1</sup> at the control of no nutrient inputs. Relative to the control treatment, there was a two-fold increase in fresh curd yield at 1.1 Kg B ha<sup>-1</sup> application. Boron application improved the shoot B content as well as its partitioning towards curd and was associated with higher B concentration in the curd. While the soil residual B was 0.26 mg Kg<sup>-1</sup> when no B was applied, it was 0.3 mg Kg<sup>-1</sup> at 4.4 Kg B ha<sup>-1</sup> application. It is concluded that soil B application tends to improve the yield and quality of cauliflower cultivated at the upland maize based system in mid-hill areas of Nepal.</p> ER -
