Evaluation of Garlic (Allium sativum L.) genotypes for growth and yield parameters under central dry zone of Karnataka

Abstract

An investigation was conducted to ascertain the Garlic (Allium sativum L.) production depends on the performance of genotypes that are suitable to different conditions imposed by specific environment. Production of Garlic in Rabi season is more important to have continuous supply round the year. So evaluation for performance of Garlic varieties is basic step towards its popularization for its successful cultivation under central dry zone of Karnataka. Keeping this in view, field experiment was conducted at Zonal Agricultural and Horticultural Research Station, Hiriyur. Ten genotypes ( NRCWG-5, Agri Found White, NRCWG-6, G-378, G-324, G-282, NRCWG-3, Rajalli Gadde, NRCWG-4, and Agri Found Parvathi were supplied under All India Network Research Project on Onion and Garlic(AINRPOG) and evaluated for growth and yield parameters under Central Dry Zone of Karnataka to identify the high yielding genotypes for this location and were tested in randomized complete block design with three replications at spacing of 15X10 cm during the Rabi season of 2013-14. The characters studied were plant height(cm), Number of leaves, leaf length, leaf width (cm), Pseudo stem length(cm), Polar diameter and equatorial diameter of bulb(cm), Average bulb weight(g), Number of Cloves per bulb, 10 Cloves weight(g), % Marketable yield(q/ha), Marketable yield(q/ha) and Total yield(q/ha). Among the genotypes tested, the results revealed that, significantly the highest total yield (62.72q/ha) and marketable yield (51.33/ha) was observed in the genotype Rajalli Gadde. The traits polar diameter of bulb (3.93 cm), equitorial diameter of bulb (4.50 cm) and Average bulb weight (81.93 g) were recorded significantly the highest in the genotype Rajalli Gadde
