Abstract
A Field experiment was conducted during 2014-2015 in the department of Plantation, Spices, Medicinal and Aromatic crops at Kittur Rani Channamma College of Horticulture, Arabhavi to study the influence of plant density and method of planting on performance of garlic var. AAS-2. The field trials were laid out in a split plot design with two main (M: planting method) and five sub treatments (S:plant density) replicated thrice.
Significant differences were observed in plant growth parameters viz., plant height, number of leaves per plant, leaf length and breadth and collar diameter. Significant differences were also observed with in yield parameter like weight of bulbs, bulb diameter, weight of cloves and bulb yield per hectare due to planting methods. Significantly highest bulb yield (6.68 t/ha) was recorded in raised bed and least bulb yield (5.73 t/ha) was recorded in flat bed. Significantly highest bulb yield (8.83 t/ha) was recorded by the treatment S1 (15 cm x 2.5 cm) followed by S4 (15 cm x 10 cm) which recorded 6.86 tonnes per hectare compared to the lowest (2.08 t/ha) recorded in S5 (Broadcasting). Among interaction effect significantly highest bulb yield (9.86 t/ha) was recorded by S1M1 followed by S1M2 (7.81 t/ha) and S4M1 (7.24 t/ha). The minimum yield was observed in the treatment S5M2 (1.84 t/ha).
Higher cost of cultivation was accounted in the treatment S1 (Rs. 1,56,160) followed by S2 (Rs. 1,23,451).Higher net returns and benefit cost ratio was recorded by raised bed (Rs. 3,05,577 and 2.50) respectively compared to crop sown in flat bed (Rs. 2,56,451 and 2.25) respectively. Among interaction effects, B:C ratio was higher in S4M1 (3.62) followed by S4M2 (3.38) and lowest was recorded by S5M2 (0.07).
