THE GOBAKHPUB MODIFICATION. 



to go into the details of the methods of the artificial regeneration 

 of sal for which the reader is referred to the Forest Pocket Book, 

 the article on the artificial regeneration of sal in Gorakhpur 63 

 and the essay on artificial reproduction 64 which is printed as an 

 appendix to this book. It will be enough to state here that teak is 

 the best species for filling up blank* in sal coppice where frost is not 

 too severe as it will keep pace with the growth of the coppice, 

 either direct sowings or root and shoot cuttings may be used. The 

 good effect of a summer fallow by inducing active nitrification in 

 the soil is well known and is as valuable in forestry as in agricul- 

 tiire, consequently the soil preparation should be done in the cold 

 weather so that the soil may be aerated and sweetened during the 

 following hot weather months prior to the start of artificial 

 reproduction. 



Taungya cultivation promises to give excellent results, but the 

 technique is still more or less experimental and has not yet been 

 standardised, and for this reason a description of the management 

 of taungyas cannot be given here. 



Ordinarily with rotations up to 30 years no division into Thedivi- 



periods is made but with rotations up to 60 years a division of the sion into 



area into periods is often convenient. For instance in Gorakhpur 

 with a rotation of 50 years it might be convenient to divide the 

 rotation to 5 periods of 10 years, corresponding to the periodical 

 revisions of the working plan for instance 



Gorakhpur sal-Coppice division into periods.
