ARTICLE 9. 

 Preparation and Management of Nursery Lines. 



Before the student can study the actual preparation and manage- 

 ment of nursery Unes, he must understand fully why and under 

 what circumstances transplants from the seed-beds must often 

 undergo a further training or schooling before being allowed to 

 leave the nursery. 



He must also remember that the planting material raised in 

 nursery lines comprises, besides seedlings, also suckers, rhizomes 

 and rhizome-shoots, slips and cuttings, layers, and grafted and 

 budded plants ; and that the seedlings may be self-sown plants 

 from the forest as well as those obtained from the nursery seedbeds. 



§ 1. Nursery lines and seed-beds compared. 



As compared with seed-beds nursery lines offer the following 

 characteristics : — 



(i) They require a much larger area of prepared ground ; 



(ii) Hence there is greater waste of manure, and 



Ciii) More water is required and the arrangements for watering 

 are proportionately much more extensive and elaborate ; 



(iv) The seedlings standing far apart, the soil deteriorates more 

 rapidly ; 



(v) For the same reason weeds are more abundant and give 

 proportionately more trouble to remove them ; 



(vi) The plants require more individual attention ; 



(vii) Greater skill and care are called for ; 



(viii) Control and management are much more difficult ; 



(ix) The seedlings being larger, their lifting up and transport 

 to the forest are more difficult and require more labour and car- 

 riage ; and, 



(x) As a consequence of all the preceding characters, they are 

 much more costly. 



, Hence nursery lines should be resorted to only when it is neces- 

 sary to raise material — 



1. For planting out in avenues, groves, parks and hedgerows. 



2. For planting up pasture lands. 



3. For planting in places exposed to chmatic extremes. 



4. For planting in rich soil liable to be overrun with large 

 strong weeds, and especially grasses possessing deep, abundant, 

 powerful and vivacious roots and rhizomes. 



5. For planting in localities subject to inundations.
