Abstract
A field experiment was conducted at College of Agriculture, Mandor,
Jodhpur during the Kharif season of 2018, to find out the suitable variety and its
optimum sowing time and spacing for higher yield, quality and net returns of carrot in
western Rajasthan. The treatments comprising two varieties (‘Pusa Rudhira’ and
‘Pusa Vrishti’), three spacing (20 cm × 10 cm, 30 cm × 10 cm and 30 cm × 20 cm) and
four dates of sowing (10th August, 25th August, 10th September and 25th September)
allocated in Factorial Randomized Block Design with three replications. Experiment
results revealed that variety ‘Pusa Vrishti’ recorded significantly higher growth
parameters while ‘Pusa Rudhira’ recorded significantly higher yield parameters, root
yield (23.8 t ha-1), quality parameters and net returns (Rs. 2,55,491) with lesser days
to marketable maturity (73.9). Among different spacing, significantly higher growth
and yield parameters were observed in widest spacing (30 cm × 20 cm). However,
root yield (24.5 t ha-1) and net returns (Rs.2,26,604) were recorded highest in S1 (20
cm × 10 cm). The 25th September sowing recorded significantly highest growth
parameters, yield parameters, yield (25.8 t ha-1) and quality parameters besides being
earliness in term of maturity (73.7 days). However, the highest net returns (Rs.
3,09,028) and B:C ratio (4.33) were recorded in 10th August sowing. The combination
of ‘Pusa Vrishti’ sown on 25th September, recorded highest plant height at 60 DAS
(39.3 cm) and fresh weight of aerial part (101.9 g) whereas, ‘Pusa Rudhira’ sown on
25th September combination recorded significantly higher values of fresh weight of
root (139.4 g), root yield (11.1 kg plot-1) and root yield (25.8 t ha-1). Hence, variety
‘Pusa Rudhira’ sown in closer spacing of 20 cm × 10 cm spacing under staggered
sowing is found to be superior in terms of yield, quality, earliness and net returns in
the arid regions of Rajasthan.
