- Abstract
The objective of this study was to develop an environmental friendly, low cost technology for cultivation of livestock forage legumes so as to minimise the use of nitrogen fertiliser (N-fertiliser) that pollute the pristine highland watersheds. Inoculants were prepared by screening several rhizobial isolates obtained from farm cultivated clover plants and selecting the most efficient strain. In field tests at three separate sites, the average amount of biomass produced by inoculated Trifolium plants was higher compared with the plants fertilised with urea. Root nodulation and other plant parameters were assessed on several randomly harvested plants 60 days after planting. The results indicate that root nodulation and plant growth increased significantly in inoculated plants. Average results obtained from nine crop cuts taken during a period of 15 months showed that regeneration and biomass production after crop cutting were better under inoculation than under N-fertiliser application. It is inferred that rhizobial inoculation has the potential to replace N-fertiliser applications to Trifolium repens L. in the Sri Lankan highland farming systems.
