Abstract:
The field experiment entitled “Effect of varied crop geometry and planting periods on growth and yield of garlic (Allium sativum L.)” was conducted with split plot design at Horticulture farm, MARS, University of Agricultural Sciences, Raichur during the year 2020-21.The crop was sown at different planting periods viz., second fortnight of October (D1), first fortnight of November (D2), second fortnight of November (D3) and first fortnight of December (D4) with varied spacings of 10 x 7.5 cm (S1), 15 x 7.5 cm (S2) and 20 x 7.5 cm (S3). The experiment was objectivated to know the response of garlic for varied crop geometry and planting periods, to standardize the suitable crop density and planting period for garlic and to workout economics of garlic for varied crop geometry and planting periods.
The results emanated from the experiment revealed that, amongst the four different planting periods, early planted crop on second fortnight of October (D1) resulted in vigorous growth and high yield through maximum per cent emergence, plant height, number of leaves, leaf area, leaf area index, plant girth, neck thickness, fresh weight of bulb, number of cloves per bulb, bulb girth, bulb length, bulb diameter, average clove weight, test weight of cloves and bulb yield. Amongst the crop geometries, lower plant density with wider spacing of 20 x 7.5 cm (S3) (6, 66,667 plants ha-1) resulted in better performance of the all parameters except the bulb yield. Maximum bulb yield was harvested with higher plant density of 13, 33,333 plants ha-1ina spacing of 10 x 7.5 cm (S1).
It was evident that, garlic planted during second fortnight of October with the spacing of 20 x 7.5 cm resulted in better performance of all the parameters. Maximum bulb yield was recorded with planting on second fortnight of October by adopting the spacing of 10 x 7.5 cm for which B:C ratio was also found to be high (2.11).
