ABSTRACT
A field experiment was conducted during Kharif season 2019 at Zonal
Agricultural Research Station, GKVK, University of Agricultural Sciences, Bengaluru.
The soil of the experimental site was red loamy sandy in nature having medium
nitrogen, low phosphorus and high potassium
content,andwas slightly acidic in nature. The treatment consisted of 5 levels
of phosphorus viz. T1 (50%Recommended
Dose of Fertilizer (RDF) P2O5), T2 (75%
RDF P2O5), T3 (100% RDF P2O5),
T4 (125% RDF P2O5) and T5 (150% RDF
P2O5) in the presence of static dose of nitrogen and potassium.
There were 5 treatments each replicated four times. The experiment was laid out
in randomized complete block design. The result showed that application of 150%
RDF of P2O5 recorded significantly higher growth
attributes viz., plant height (T5: 128.125 cm) and the number of
leaves per plant (T5: 11.1 at 60 Days after Sowing(DAS)). However,
the application of 100% RDF of P2O5 treatment recorded a
significantly higher seed yield (T3: 296.25g).
