The performance of 24 ber (Z. mauritiana) in terms of growth, yield and
yield components were studied under the tarai conditions of
Uttaranchal, India during 1998-99. Sanaur 6 recorded the highest tree
height (5.75 cm) and spread (11.90 m), trunk girth (2.13 m), cross
trunk sectional area (3616.08 cm2) and volume (1698.39 m3). Rohtak
Gola, Seo, Nazuk, Narikeli and Sanaur 2 recorded the highest shoot
length (248 cm), number of leaves per shoot (515.50), leaf length
(10.68 cm), length:breadth ratio (2.32) and photosynthetic efficiency
(0.182 mg/cm2/h), respectively. Sanaur 3 recorded the highest leaf
breadth (7.71 cm) and area (43.19 cm2); ZG3 recorded the highest number
of fruits per shoot (50.50) and per tree (11665.50), and yield (214.40
kg); and ZG 2 recorded the highest yield efficiency by weight (0.215
kg/cm2) and number of fruits per m3 volume of tree (59.05). |
