Abstract
A field experiment was conducted during rainy season of 2000-01 at
Main Research Station, University of Agricultural Sciences, Dharwad, to
Investigate the effect of row spacing and fertilizer levels on growth and yield of
groundnut genotypes. This experiment was laidout in a split-plot design with
three replications. Treatments consisted of three groundnut genotypes viz.,
GPBD-4, TGLPS -3 and JL-24 as main plots and four levels of spacing and
fertilizers viz., S,F - 30 x 10 cm + 100% RDF (25: 75 : 25 kg N, PO, KO/ha),
S,F2-30x 10 cm + 150% RDF (37.5 : 112.5 : 37.5 N, PO, KO/ha), 5 , - 45
X 10 cm + 100% RDF and S / - 45 x 10 cm + 150% RDF) as sub-plot
treatments.
The results showed that, groundnut genotypes differed significantly.
Genotype GPBD-4 recorded significantly higher dry pod, kernel and oil yield
(2892.58, 2256.33 and 1093.87 kg/ha, respectively) as compared to TGLPS-3
(2685.30, 1822.17 and 865.07 kg/ha, respectively) and JL-24 (2475.50,
1829.33 and 862.34, kg/ha, respectively).
There was significant difference in dry pod, kernel and oil yield due to
row spacing. Closer row spacing of 30 x 10 cm recorded higher dry pod yield
(2754.55 kg/ha), kernel yield (1980.50 kg/ha) and oil yield (943.74 kg/ha) as
compared to wider row spacing of 45 x 10 cm (2614.39, 1957.80 and 937.11
kg/ha), respectively).
Increasing the levels of NPK from 100 to150 per cent of recommended
dose resulted in numerical increase in dry pod, kernel and oil yield. Growth and
yield characters followed the similar trend.
The interaction effects were significant due to genotypes, spacing and
levels of NPK. Genotype GPBD-4 recorded higher dry pod yield (3223.00 kg/ha),
kernel yield (2580.00 kg/ha) and oil yield (1238.67 kg/ha) at wider row spacing
of 45 X 10 cm with lower levels of NPK (25: 75: 25 kg N, PO and KO/ha).
The genotype GPBD-4 recorded significantly higher net returns (Rs.27380/
ha) and B:C ratio (3.29) as compared to TGLPS-3 (Rs.l6977/ha and 2.09,
respectively) and JL-24 (Rs.13807/ha and 1.96, respectively) at wider row
spacing of 45 x 10 cm with lower levels of NPK (25: 75: 25 kg N, PO and KO/
ha) application.
