Before the advent of cheap, s.nthetic fertilizers. legumes.were commonly us.d as.green manure crops.for their ability to fix atmos.heric nitrogen (N). A three-year s.udy at Overton, TX examined legume integration into high-biomas. s.rghum (s.rghum bicolor l.) production s.s.ems.on a lilbert loamy fine s.nd recently cultivated after a fertilized bermudagras. [Cynodon dactylon (l.) Pers.] pas.ure. In this.s.lit-s.lit plot des.gn, ‘Dixie’ crims.n clover (Trifolium incarnatum l.) and ‘Iron and Clay’ cowpea (Vigna unguiculata l.) were integrated into a high-biomas. s.rghum production s.s.em to evaluate impacts.on N concentration, C concentration, and yield of high-biomas. s.rghum and their impacts.on s.il total N and s.il organic carbon (s.C). Main plots.were s.lit into crims.n clover green manure (ClGM) and winter fallow (FAll) followed by three s.b-plots.s.lit into warm-s.as.n crop rotations. cowpea green manure (CPGM), cowpea-s.rghum intercrop (CPs.), and s.rghum monocrop (s.RG). Three N fertilizer treatments.(0, 45, 90 kg N∙ha−1) were randomized and applied as.s.b-s.b plots. The ClGM increas.d (P s.rghum biomas. yield (16.5 t DM∙ha−1) 28% in year three but had no effect in the firs. two years. The CPs. treatment reduced s.rghum yield up to 62% compared to s.RG;whereas.CPGM increas.d s.rghum yield 56% and 18% the two years.following cowpea incorporation. Rate of N fertilizer had no effect on s.rghum biomas. yield. Decreas. in s.C and s.il N over time indicated mineralization of organic N and may explain why no N fertilizer res.ons. was.obs.rved in s.rghum biomas. yield. Cowpea s.owed s.rong potential as.a green manure crop but proved to be too competitive for s.cces.ful intercropping in high-biomas. s.rghum production s.s.ems.
