EFFECT OF CUTTING LENGTH, THICKNESS AND PLANTING TIMES ON THE SUCCESS OF VEGETATIVE PROPAGATION OF JIGA (Garuga pinnata) (Pages : 31 - 36)
M. H. A. KHANAM, M. A. HOSSAIN I. JAHAN, M. A. HUSSAIN AND M. A. HOSSAINAn experiment was conducted to find out suitable planting time and cutting size (length and thickness) on the success of vegetative propagation of Jiga (Garuga pinnata) at the Agroforestry Farm, Department of Agroforestry, Bangladesh Agricultural University, Mymensingh, during the period from March to September, 2004. The treatments were three planting times viz. third week of March, April and May, three different cutting lengths viz. 50, 25 and 12.5 cm and thickness viz. thick stem cuttings of 2.75 cm diameter ranging from 2.5 to 3.0 cm in thickness and thin stem cuttings of 1.5 cm diameter ranging from 1.0 to 2.0 cm in thickness. The highest percent survivability and effective branches (56.9% and 1.21, respectively) was found with 50 cm long cuttings. Thick cuttings gave the highest percent survivability and effective branches (38.90% and 0.75, respectively). March plantation gave the highest percent survivability and effective branches (59.20% and 1.46, respectively). The interaction effects between the cutting length, cutting thickness and planting time showed a very clear and decisive result of 100% survivability with 50 cm long and thick cuttings in March plantation. The highest 3.78 number of branches was observed with 50 cm long, thick cutting in March plantation. Both survivability and branch development of this study showed that March plantation had better effects compared to the April plantation.Download
