Abstract
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.
