COMPARATIVE GROWTH OF NATURAL AND PLANTATION 
SAPLINGS , 
(Data collected by the Forest Research Institute.) 
The development of Deodar saplings growing in a natural crop 
and in a plantation was studied at Konain, Chakrata Division, United 
Provinces, by preparing stem analyses of 18 natural saplings and of 
14 plantation saplings. Sections were cut at every 5 feet in height 
of the 32 trees. The natural saplings ranged in height from 29 to 46 
feet, in age from 34 to 46 years, and in girth from 12-8 to 17*1 inches. 
The plantation saplings ranged in height from 32 to 44 feet, in age from 
32 to 42 years, and in girth from ll'l to 19*2 inches. The early deve¬ 
lopment of natural saplings was calculated from observation in experi¬ 
mental plots. 
The arithmetical mean of the 18 natural saplings showed : Age 40 
years, Height 37 feeb, Quarter-girth Volume 1*73 cubic feet. Form 
factor *50. The arithmetical mean of the 14 plantation saplings 
showed : Age 37 years, Height 37 feet, Quarter-girth Volume 1-58 
cubic feet. Form factor *48.
