ABSTRACT
Experiments were conducted at Peshawar (Sub-tropical, 320 m elevation, 407 mm annual rain fall, canal irrigated) and Dungagali (moist temperature, 2500 m elevation, 1650 mm annual rain fall) to develop methods for growing , rhizomes were
collected in November from Murree and stored for one and two months at Peshawar in1:1 soil and sand mixture at one meter depth and planted after the storage period. Two months storage period gave significantly high (at 5%level) sprouting as compared to one month storage. Planting of full size rhizomes were tested against rhizome pieces (5, 7.5 and 10 cm). though full rhizomes gave significantly higher sprouts, planting 5 cm pieces with one or two buds each would give a higher total number of plants. At Dungagali July planting gave significantly higher sprouts on 25th August, 1977 as compared to November planting. Indole acetic acid treatment did not significantly
increase sprouting.
