Description A field experiment was conducted to study the influence of boron and molybdenum
on growth and yield of groundnut crop in farmer’s field which are deficient in boron (0.46
mg kg-1) and molybdenum (0.24 mg kg-1) at Neeralkatti village of Dharwad district. There
were 11 treatments in different combinations of boron and molybdenum applied to soil and
through foliar spray. The experiment was laid out in a randomized complete black design
with three replications. Results indicated that, growth and yield components of increased
significantly due to combined application of boron and molybdenum (Borax @2.5 kg ha-1 +
sodium molybdate @1.5 kg ha-1+ borax foliar spray @ 0.2% + sodium molybdate
foliar spray @ 0.05%) over rest of the treatments. The increase in groundnut pod yield due to
this treatment was 29.05% compared to control. The increase in pod yield of groundnut was
attributed to increases in growth and yield parameters and nutrient absorption, as a
consequence of combined supply of boron and molybdenum which is essential for enhancing
N2- fixation. The cost benefit ratio (3.55) of the treatment receiving borax @ 2.5 kg ha-1+
sodium molybdate @ 1.5 kg ha-1+ borax foliar spray @ 0.2% + sodium molybdate
foliar spray @ 0.05% suggested that groundnut yield can be increased by combined
application of boron and molybdenum as both soil and foliar spray. The boron and
molybdenum concentration and uptake was significantly enhanced due to combined
application (soil and foliar) of boron and molybdenum. Boron and molybdenum status of soil
after harvest the crop were 0.512 and 0.270 mg kg-1 respectively.
