The effects of nitrate nitrogen and phosphate on the nodulation and nitrogen fixation of white cliver (Trifolium repens L.): a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University [PDF]
, 1974 It is a well established fact that the presence of nitrate ions can depress nodule development on legume roots, but recent studies in Queensland (Gates, 1970) have shown that this sensitivity can be ameliorated if phosphate levels are maintained at a ...

Direct amplification of nodD from community DNA reveals the genetic diversity of Rhizobium leguminosarum in soil [PDF]
, 2001 Sequences of nodD, a gene found only in rhizobia, were amplified from total community DNA isolated from a pasture soil. The polymerase chain reaction (PCR) primers used, Y5 and Y6, match nodD from Rhizobium leguminosarum biovar trifolii, R. leguminosarum

Influence of clover species in mixtures with grasses on fatty acid composition of mixtures [PDF]
, 2006 White clover (WC, Trifolium repens L.) or red clover (RC, Trifolium pratense L.) was grown in mixture with grasses. Samples of the mixtures and pure clovers were taken during three cuts, and the fatty acids (FA) compositions were determined.
