Effect of Sprays of Growth Regulators and Chemicals on Growth and Yield of Garlic (Allium sativum L.)

Field experiment was conducted at Kittur Rani Channamma College of Horticulture, Arabhavi, Gokak Taluk, Belgaum district of Karnataka state during the rabi season of the year 2010–2011 to study the effect of sprays of growth regulators and chemicals on growth and yield of garlic (Allium sativum L.). Effect of sprays of growth regulatorsVIZ., Maleichydrazide, Cycocel, Carbendazim, Dithane M-45 and Borax was studied either alone or in combinations for its effect of growth and yield of garlic cv. Vannur Local. Sprays of growth regulators and chemicals significantly affected the plant height, number of leaves per plant, leaf length and breadth and collar diameter. However, yield parameters like bulb weight, bulb diameter, clove weight, number of cloves per bulb and bulb yield werenot affected by the sprays of growth regulators and chemicals. Sprays of growth regulators and chemical showever enhanced yield. The highest yield (7.31 t/ha) was recorded in T₄ (Cycocel 1000 ppm).
