Abstract
An investigation was carried out to study the “Effect of spacing and
biofertilizers on growth, yield and quality of garden cress (Lepidium sativum L.)”
during rabi, 2017-18 at Main Horticultural Research and Extension Centre (MHREC),
UHS, Udyangiri, Bagalkot which comes under Northern Dry Zone of Karnataka.
Significantly higher plant height (75.40 cm), biomass production per plot (9.70
kg) and per hectare (7.19 t), and the highest number of days taken for 50 per cent
flowering (44.83) were recorded when garden cress was supplied with Azotobacter
chroococcum applied @ 5 kg ha-1 + phosphate solubilizing bacteria @ 5 kg ha-1 with
spacing of 30 cm x 10 cm (T1). Maximum number of primary branches (19.12), number
of leaves (44.0) and total dry matter accumulation (44.90 g) per plant were observed in
the treatment applied with Azotobacter chroococcum applied @ 5 kg ha-1 + phosphate
solubilizing bacteria @ 5 kg ha-1 with spacing of 45 cm x 20 cm (T6).
Similarly, yield parameters such as number of siliquae per plant (1473.79), seed
yield per plant (21.33 g) and test weight (2.20 g) were also significantly higher in T6.
Significantly higher seed yield (2.50 kg/plot & 1.85 t/ha), harvesting index (0.383) and
oil yield (291.07 kg/ha) were recorded in T1. But the length of silique, number of seeds
per silique and oil content were not responded significantly due to biofertilizers and
spacing levels.
Higher net returns (1, 27,789 Rs./ha) and B: C ratio (2.68) was obtained with the
application of Azotobacter chroococcum @ 5 kg ha-1 + phosphate solubilizing bacteria
@ 5 kg ha-1 with spacing of 30 cm x 10 cm (T1).
Hence, crop supplied with A. chroococcum @ 5 kg ha-1 + PSB@ 5 kg ha-1 with
spacing of 30 cm x 10 cm was found better for the cultivation of garden cress under
Northern Dry Zone (Zone 3) of Karnataka.
