YIELD AND CHEMICAL COMPOSITION OF DRYLAND LUCERNE ON THE EASTERN TRANSVAAL HIGHVELD.
Three methods of interrow cultivation viz, rip (40—50 cm) shallow tine cultivation (5—10 cm) and control (no cultivation) were compared during the 1982/83 and 1983/84 growing seasons. This was done in an existing stand of lucerne which was established in 0,9 m rows. Factors such as soil moisture and weed infestation determined the time of cultivation.
Interrow cultivation increased dry matter yield appreciably, but no significant differences in yield were recorded between the two cultivation methods. The positive effect of cultivation was more pronounced in the 1982/83 growing season which was much drier than the following season.
Significant differences in moisture, as well as protein contents, were recorded between cultivation and no cultivation in the dry 1982/83 growing season.
