    Effect of foliar application of boron and molybdenum on productivity and quality of cauliflower in Kullu valley of Himachal Pradesh
    (Palampur, 2022-11-27) Sankhyan, Pankaj Kumar; Parmar, Devender Kumar
    A field experiment was carried out during kharif 2021 at the experimental farm of CSK HPKV Hill Agriculture Research and Extension Centre, Bajaura, Kullu to assess the effect of foliar applied B and Mo on cauliflower. Three foliar concentrations of boron (0.034%, 0.051%, 0.068%) and molybdenum (0.10%, 0.15%, 0.20%) along with two control treatments (NPK alone and NPK+FYM) were replicated thrice and evaluated in a randomized block design. All the treatments except NPK alone received recommended dose of FYM @20 q ha-1. The foliar application of B and Mo was done at 30, 45, and 60 days after transplanting. The results revealed that the crop growth parameters yield attributes, yield, quality, and nutrient uptake were significantly affected by the foliar spray of boron and molybdenum. The growth parameters, yield attributes, curd quality, nutrient uptake, curd yield, net returns and benefit cost ratio increased with increasing the concentration of B from 0.031% to 0.068% and that of Mo from 0.10% to 0.20% and the maximum curd yield was recorded with 0.068% and 0.20% concentration of B and Mo, respectively. The foliar application of boron and molybdenum had a non-significant effect on soil pH, organic carbon, available NPK, B and Mo but significantly influenced the availability of micronutrient cations after the harvest of cauliflower. It is concluded from the present study that the application of B @ 0.068% and Mo @ 0.20% at 30, 45, and 60 DAT along with basal dose of recommended NPK+FYM was most remunerative for cultivation of cauliflower during kharif season in Kullu valley of Himachal Pradesh.
