INFLUENCE OF EYE NUMBER ON A SEED AND POTASSIUM ON GROWTH AND YIELD OF TURMERIC

Abstract

The study was conducted at the Horticultural Farm of Sher-e-Bangla Agricultural University. Ohaka during the period from April 2008 to April 2009. The experiment consisted of two factors. Factor A: Three levels of number of eye in each rhizome. E1 : 1 eye. E2 : 2 eyes and E 3 : 3 eyes and Factor B: Four levels of potassium, K 0 : 0 kg, K1 : 90 kg, K2 : 110 kg and K 3 : 130 kg K2 0/ha respectively. The experiment was laid out in Randomized Complete Block Design (RCI3D) with three replications. In case of number of eyes, the highest yield (24.58 tlha) was recorded from E2 and the lowest (22.31 tlha) was from E1 . In case of potassium, the highest yield (26.81 t/ha) was observed from K 3 and the lowest (15.14 tlha) was found from K0 . For combined effect E 2K1 produced the highest yield (28.82 tiha) and lowest (14.89 tlha) from E 1 K0 . The highest benefit cost ratio (2.50) was noted from E2K3 and the lowest (1.38) from E 1 K0 . So, two eyed rhizome with 130 kg K 2 0/ha was found suitable for growth and yield ortunneric.
