Effect of successive cuttings on nodulation and nitrogen fixation of Leucaena leucocephala using 15N dilution and the difference methods

Autor: Sanginga, N. Zapata, F. Danso, S.K.A. Bowen, G.D.

Despite the widespread use of Leucaena leucocephala in alley cropping systems, little information is available on the effect of different magagement practices on its nitrogen fixation. We studied the effects of three successive cuttings at 12 week intervals on nodulation and nitrogen fixation of ...

Influence of reference trees on N2fixation estimates in Leucaena leucocephala and Acacia albicia using 15N_ labelling techniques+A51

Autor: Sanginga, N. Danso, S.K.A. Zapata, F. Bowen, G.D.

We examined the suitability of four reference crops, i.e., two non-fixing trees,Cassia siamea andEucalyptus grandis, and two uninoculated fixing trees,Leucaena leucocephala andAcacia albida, for measuring fixed N2 fixed in inoculatedL. leucocephala andA. albida grown for 36 weeks in pots. The15N ...

Field measurements of nitrogen fixation in leguminous trees used in agroforestry systems: influence of 15Nlabelling approaches and reference trees

Autor: Sanginga, N. Danso, S.K.A. Zapata, F.

Appropriate 15N-labeling methods are crucial for estimating N2-fixation in trees used in agroforestry systems. A 4-year field experiment was conducted on an Alfisol in Southwestern Nigeria to compare the estimates of Na fixed in Leucaena leucocephala, using two non-N2-fixing leguminous trees, Sen...
