Description An experiment entitled INFLUENCE OF PRE AND
POST- SOWING IRRIGATION, SEEDING METHODS AND SEED
DENSITIES ON STAND ESTABLISHMENT OF GROUNDNUT AFTER
KHARIF RICE was conducted on sandy loam soil under
irrigation at the College Farm, Rajendranagar,
Hyderabad during rabi 1991-92. The experiment was laid
out in strip plot design with three replications. The
treatments comprised of combination of two irrigations
(pre and post-sowing irrigation) and two seeding
methods {behind country plough and country seed drill),
under main plots and th;ie levels of seed densities
{5.5, 5.0 and 4.5 lakh ha ) as sub-plots.
Small size clods, low mean weight diameter and
low bulk density of soil (30 DAS) were observed in the
crop field subjected to pre-sowing irrigation. T~i
plant stand, plant height, branches, dry matter pla~r
and dry matter per unit_frea, pod yield (2704 kg ha ),
haulm yield (3957 kg ha ), NPK uptake, gross returns
(Rs.18285), net returns (Rs.9034) and benefit-cost
ratio {l.96) were more with crop subjected to presowing
irrigation. The yield components such as total
pods, filled pods, pops, 100 kernel weight and shelling
per cent were not significantly influenced by pre and
post-sowing irrigation.Pla~i stand, ~lant hei~h~, branches, dry
matter plant and per unit area, yield components, pod
yield and NPK uptake were not significantly influenced
by_Ieeding methods. However, the haulm yield (3734 kg
ha ), gross returns (Rs.17171), net returns (Rs.8002)
and benefit-cost ratio (1.88) were more when sown with
country seed drill (gorru). ·
High seed densities result~~ in less number of
branches, reduced dry matter plant • Similar red~1-
tion in yield comp~fents like numb~! of pods plant ,
filled pods plant , pops plant and pod weight
plant-l was observed. However, as the seed density
increased, dry matter per unit area, NPK uptake, pod
and haulm yield ha were increased, which resulted in
higher gross and net returns.

None of the interaction effects for any of the
characters, yield components, pod and haulm
NPK uptake and monetary returns was significant
of the crop growth stages under study.
From the present investigation considering the
input-output ratio it may be suggested that sowing the
groundnut after one pre-sowing irrigation with country
se~~ drill (gorru) adopting a seed density of 5.0 lakh
ha was recommended in rice fallows for realising
optimum yields and higher returns.
