Description A field experiment was conducted at Main Agricultural Research Station
(MARS), University of Agricultural Sciences, Dharwad, during Rabi/Summer 2011-12 to
know the effect of water soluble fertilizers on growth, yield and oil content of groundnut (cv.
TAG 24) in a Vertisol of Northern Transition Zone of Karnataka. There were 10 treatment
combinations consisting of combination of FYM and reduced recommended dose of NPK
through soil application as basal and foliar spray of soluble fertilizers at 30, 45 and 60 days
after sowing (DAS). The experiment was laid out in a complete randomized block design
with three replications.
Application of FYM + 100% RDF + foliar spray of fertilizers at 30, 45 and 60
DAS recorded higher pod yield (5615 kg/ha) which was 22 % higher over application of
100% RDF (4601 kg/ha). However, it was on par with the treatment receiving FYM + 85 %
RDF + foliar spray of fertilizers at 30, 45 and 60 DAS.
The concentration of major and micro nutrients was higher in kernel compared to
haulm at harvest. The concentration of nutrients as well as uptake was highest in the
treatment receiving FYM + 100% RDF + foliar spray of fertilizers at 30, 45 and 60 DAS at
all the crop growth stages. The concentration of nutrients was highest at 30 DAS and
decreases as the crop growth advances. The uptake of nutrients was positively and
significantly correlated with dry pod yield and oil yield. The nutrient status of the soil after
harvest of the groundnut was higher in the treatment receiving FYM + 100% RDF + foliar
spray of fertilizers at 30, 45 and 60 days after sowing. But the treatment receiving FYM + 85
% RDF+ foliar spray of fertilizers at 30, 45 and 60 DAS recorded the highest B:C ratio.
