Field study was carried out to enhance
saffron productivity by land configuration and corm
intensity manipulation. The principal findings revealed that
in land configurations, raised beds resulted in significant
improvement in average, total and corm yield of saffron
(4.16 kg/ha, 22.38 kg/ha and 33.76 t/ha) over flat beds (1.57
kg/ha, 9.76 kg/ha and 9.86 t/ha) while in corm intensities,
maximum average, total and corm yield of saffron was
obtained in 15 lakh/ha corm intensity (3.19 kg/ha, 15.98
kg/ha and 28.49 t/ha) as against minimum in 5 lakh/ha
corm intensity (2.15 kg/ha, 10.76 kg/ha and 13.89 t/ha),
respectively. The land configurations and corm intensities
interaction significantly enhanced average and total yield
of saffron, and maximum were found (4.76 and 23.84
kg/ha) in raised beds with 10 lakh/ha corm intensity and
minimum (1.20 and 6.00 kg/ha) in flat beds with 5 lakh/ha
corm intensity. High corm intensity increases total saffron
yield that arises from increase in number of flowers from
unit space. Land configurations significantly affected stigma
length and fresh weight owing to improved drainage and
microclimatic condition which altered corm production
behaviour while foliage length, number of leaves, flowers
number and saffron yield were significantly affected by
both land configurations and corm intensities and increased
in successive years. The combination of raised beds with
10 lakhs/ha corm intensity proved economically viable
with highest benefit cost ratio of 4.34 under irrigated
condition. Flat beds and high corm intensity of 15 lakh
corm/ha are not suggested owing to poor drainage and high
corm cost. Management of optimal soil moisture through
critical irrigation during active growth play crucial role
in enhancement of saffron yield, corm multiplication and
corm rot management.
