“…The superior performance of'Nz lotus plants compared to N 2 white clover plants at 50 and 500 ppm is consistent with the observations of others who found that lotus was tolerant of low P supplies (Brock 1973;Crush 1974;Gibson et al 1975;Hall & Armstrong 1979;Nordmeyer & Davis 1977). In this experiment the yield of N2 lotus and white clover plants at 1500 ppm was not significantly different, although in other situations lotus has been observed to give higher yields than white clover at high P levels (Gibson et al 1975;Lowther 1976).…”

White clover and lotus were grown in a controlled environment at P levels of 50, 500, and 1500 ppm and either inoculated with rhizobia (Ni) or given KN03 (N03). Na plants of lotus and white clover had different responses to P. The response of N03 plants to P was the same in both species. This implies that the reason(s) for the difference in response between Na plants lie in differences in the structure and function of the symbiotic association. Lotus plants had a greater proportion of plant dry weight, P, and N in their nodules than did white clover. White clover nodules had higher relative growth rates and relative rates of accumulation of P and N than those of lotus and, in the early stages of growth, were more efficient. At .1500~pm P, the yield of N03 plants was greater than that of Nz plants In both species, It IS suggested that the growth of Nz plants at the high P level was limited by N. These plants appear to have been unable to fIX sufficient N for them to have yields similar to N03 plants.

Suckling clover has a smaller yield than the other species at high P levels but is able to survive and grow in soils low in P (Brock 1973). Red and white clover have a high yield but require high levels of P to maintain growth. Lotus can Received 9 July 1980; revision 2 February 1981…”

White clover, red clover, suckling clover, and lotus were grown under a controlled environment in soil to which phosphorus had been added at levels of 50, 250, 600, and 2000 ppm w/w. Growth analysis was used to explain differences in yield in terms of attributes describing growth, P uptake, and assimilation. The yield of white clover, red clover, and lotus increased markedly with P supply. Suckling clover responded less to P and its yields were smaller than those of the other species except that of lotus at 50 ppm. In all species the rate ofP uptake per unit root length increased with P supply. There were differences in uptake rate among species but these could not be consistently related to differences in yield. The efficiency with which absorbed P was used in the production of dry matter declined as the P supply increased in all species. Lotus used P with the greatest efficiency. Root/shoot ratios and root length/weight ratios were affected by an increase in P supply. Suckling clover had the highest root/shoot ratios, and lotus had the lowest. Suckling clover also had high root length/weight ratios. For these legumes, attributes such as root/shoot ratio, root length/weight ratio, P concentration, and inherent size appear to be more useful than P uptake in explaining response to P.

Ryegrass was sown alone and in combination with white, red, subterranean, or alsike clovers in small plots at 3 sites in Otago. At 2 sites lucerne was also sown. Plots were cut regularly over a 3-year period, and all herbage was removed. Nitrogen yields were measured in harvested herbage separated into ryegrass and sown legume components. Relative to other species, and in terms of N uptake, white clover performed well at all sites, especially at Berwick, a moist cool site; alsike clover performed well at Berwick and moderately well at Invermay (intermediate climatic conditions) and Dunback (dry mild site); red clover was poor at Berwick but good at Invermay and Dunback; and subterranean clover was very poor at Berwick and Invermay, but moderately good at Dunback. Highest N yields in clover herbage over the last 2 years were 237 and 123 kg/ha/year from white clover at Invermay and Berwick and 231 kg/ha/year from red clover at Dunback. Lucerne N uptake averaged 630 kg/ha/year over the last 2 years at Invermay. %N content of all legumes was consistently depressed by dry conditions. Subterranean clover consistently had lower %N than the other species. Initially, ryegrass N uptake was depressed by clover, but in the final year there was evidence from % Nand N uptake measurements that ryegrass benefited marginally from association with clovers at Invermay and Dunback, but not at Berwick. However, this benefit could not with certainty be ascribed to N transfer from clovers to ryegrass. 201
