Phosphorus Levels

The effects of a wide range of phosphorus levels on the growth and uptake of phosphorus by 30 accessions of the legume genus Stylosanthes, representing seven species, were compared in a glasshouse experiment. The basic data from the experiment were subjected to a numerical classification, and accessions with similar patterns of response were grouped to simplify description and interpretation of the results. Differences in growth and phosphorus uptake under conditions of severe deficiency were fairly small, but there were appreciable differences between groups in the dry matter produced per unit phosphorus absorbed. With progressive improvement in the supply of phosphorus, large differences developed between the groups in growth and phosphorus uptake. One group, in which nodulation was partially or completely ineffective, responded poorly in growth and phosphorus uptake to additions of phosphorus. Other groups, however, were effectively nodulated, and appeared to differ considerably in their inherent growth rates and hence in their uptake of phosphorus during the 55 days of the experiment. At moderately high levels of applied phosphorus (equivalent to between 96 and 192 kg P/ha) accessions in several groups developed foliar symptoms resembling 'phosphorus toxicity', had depressed yields of dry matter, and accumulated phosphorus in their tops to high concentrations.

Phosphorus Levels

Phosphorus supplied as mono-sodium phosphate depressed the growth of subterranean clover and oats grown on Muchea sand in pot culture. In both plants the detrimental effects appeared at phosphorus levels equivalent to about 2-4 cwt. per acre superphosphate, provided both nitrogen and lime were in very short supply. Adequate nitrogen, as sodium nitrate, invariably overcame the toxic effects of phosphorus within the range of levels examined. With the clover, nodulation was usually poor, but some evidence is presented in which "heavy" inoculation with Rhizobium markedly increased nodulation and alleviated the toxic effects. Nodule numbers in the clover were increased by addition of lime and in most instances the beneficial effects resulted from enhanced nitrogen supply. Lime was advantageous to the growth of oats, also, wherever applied nitrogen was low. Possible explanations of this are suggested. Phosphorus toxicity symptoms are described for both plants and the relation to percentage total phosphorus in the leaves is discussed. Figures in excess of 1.4 per cent. and 3 per cent. total phosphorus were found in affected leaves of subterranean clover and oats respectively. Identical symptoms were observed in clover with the mono- and dibasic phosphates of sodium, calcium, and potassium.
