Effects of Different Planting Densities and Nitrogen Doses on Yield and Quality Properties of Taro (Colocasia Esculenta var. Esculenta)

Abstract

This study was conducted to determine the effects three of planting densities (100 cm x 30 cm, 100 cm x 40 cm, 100 cm x 50 cm,) and three nitrogen doses (100 kg/ha, 175 kg/ha, 250 kg/ha,) on yield and quality of Taro under Mut/Mersin(Icel)/Turkey ecological conditions between April-November in 2014. The cormels were planted on April 1st, 2014. The experiment was carried out randomized complete split plots in block design with three replications. Harvest was done on November 1st, 2014. The average cormel weight was affected significantly by planting densities and nitrogen doses. When planting spaces was increased, the average corm weight was decreased. When nitrogen doses were increased, the average corm weight was increased. The maximum corm weight (295,87 g) was obtained from 100 cm x 40 cm at planting density and 250 kg/ha nitrogen dose. The marketable yield was affected significantly by planting densities, while it was not affected by nitrogen doses except control. When planting spaces was increased, the marketable yield was decreased. When nitrogen doses were increased, the marketable yield was not increased. The maximum marketable yield (7,93 t/ha) was obtained from 100 cm x 30 cm at planting density and 175 kg/ha nitrogen dose. The cormels number per plant was not affected significantly by planting densities and nitrogen doses. The maximum cormels number per plant (7,98 per plant) was obtained from 100 cm x 40 cm at planting density and control application.
