An analysis of the objectives of resting grassveld

Abstract

The objects of various types of rests which may be applied to grassveld are analysed and an attempt is made to define the different types of rests which are at present in use. These are categorized into six major groups:

1. seeding rests — as defined ;

2. seedling establishment rests — as defined ;

3. tillering rests — to encourage lateral tiller development;

4. herbage accumulation rests — for the accumulation of herbage for foggage, hay or far burning for the control of encroaching bush;

5. vigour rests — for the establishment of pre‐defoliation reserve levels (recovery rests), for the accumulation of reserves for anticipated periods of stress (reserve accumulation rests) and for the promotion of a large assimilatory system to ensure rapid current growth rates (forage production rests); and

6. period of absence — short term withdrawal of little direct benefit to the veld.

UITTREKSEL

Die doel van verskeie tipes rus van grasveld word ontleed en ‘n paging word aangewend om die verskillende tipes rus wat huidig gebruik word, te defineer. Die verskiliende soorte veldrus is in ses hoof‐groepe gekategoriseer en uiteengesit as volg :

1. saadrus — soos gedefinieer ;

2. saailing vestigingsrus — soos gedefinieer ;

3. lootontwikkelingsrus — om basale lootontwikkeling aan te moedig;

4. loof‐akkumulasie‐rus — vir die akkumulasie van blaarmateriaal vir reserwe winter weiding, hooi of vir vetdbrand vir die beheer van bosindringing ;

5. groeikragrus — vir die herstetting van voor‐ontblarings reserwevlak (herstel rus), vir die akkumu‐lasie van reserwes vir voorsiene tye van spanning (reserwe‐akkutnulasie rus) en vir die bevordering van ‘n groot assimmilasie sisteem om snelle onmiddelike hergroei te verkry (voerproduksierus) : en

6. periode van afwesigheid — korttermyn rus tot min direkte voordeel vir die veld.
