“…Not to scale. Lechtova-Trnka, 1931;Lira, 1977; Quifiones as cited in Domingo, 1983;Rothschild, 1970). Multiple separate evolutions of the nitrogen-fixing symbioses in the Leguminosae appear implausible, however, particularly because, in each of the three major nodulating groups of the Leguminosae, nodulation occurs with both Rhizobium and Bradyrhizobium (Barnet et al, 1985;Dreyfus and Dommergues, 1981;Jenkins et al, 1988;Martinez-Romero, 1994;Moreira et al, 1993;Moreira and Franco, 1994;Turk and Keyser, 1992;Zhang et al, 1991).…”

It is generally believed that only the nodulating species of the Leguminosae fix atmospheric nitrogen; however, anatomical, ecological and taxonomic considerations indicate that non-nodulating legume species may also fix nitrogen. To test whether nitrogen-fixing symbioses in the Leguminosae might extend to the non-nodulating species, a survey of the Leguminosae was conducted: living plants of non-nodulating species were assayed using acetylene reduction. Ethylene evolution, indicating apparent nitrogenase activity, was detected in non-nodulating species representing the major taxonomic groups of Caesalpinioideae as well as in non-nodulating species of the Papilionoideae and Mimosoideae. Non-nodules nitrogen fixation appears to have provided evolutionary precursors for the nodular symbiosis in the Leguminosae.

“…In many cases the literature is ambiguous. Bauhinia for example is generally considered to be a non-nodulating genus (Allen et al, 1981, list 27 species reported to lack nodules and Faria et al, 1984 have added a futher 4) and yet Quinones (cited by Domingo, 1983) claims to have isolated rhizobia from nodules o f B.purpurea (one of the species for which Allen et al, 1981 cite three negative reports of nodulation). Parkinsonia aculeata is listed as nodulated by Halliday et al (1981), but the references given to support this all report absence of nodules, so one suspects that a '+' was included in the table instead of a Extensive searches for nodules in Brazil (Faria pers.…”

1.Land use systems in which effects of trees on soils play an important part are protective forestry, reclamation forestry (of eroded or salinized land or moving sands), production forestry, agroforestry and applications of these in watershed management. 2.There are some 20 distinct agroforestry practices, defined as arrangements of trees and herbaceous components in time and space. 3.Eleven processes are listed by which trees may improve soils, not all of which are proven. 4.A computerised model, Soil Changes Under Agroforestry (SCUAF), indicates a potential for agroforestry to achieve a steady state of soil fertility under productive use; some critical assumptions in the model require experimental testing.

“…ex Del. (Das et al 2001) and Sesbania sesban (L.) Merr, (Domingo 1983), are commonly used as agroforestry tree species in Bangladesh because the four tree species can improve the soil condition through atmospheric N 2 fixation (Uddin 2003).…”

The effects of different inorganic fertilizers (Urea and Triple Super Phosphate (TSP)) on seedling growth and nodulation capabilities of four agroforestry tree species (Albizia chinensis, A. saman, Acacia nilotica and Sesbania sesban) were compared. The nodulation of these seedlings were treated with different fertilizer treatments (at the rate of urea 40 kg hm -2 , urea 80 kg hm -2 , TSP 40 kg hm -2 , TSP 80 kg hm -2 , (urea+TSP) 40 kg hm -2-and (urea+TSP) 80 kg hm -2 ) after one month of seed germination. The results revealed that the seedling growth was enhanced significantly with moderate fertilizer treatment. In some cases, the higher levels of fertilizers reduced the seedling growth. The study also revealed that the nodulation in nodule number and size was significantly inhibited by the application of N fertilizer (Urea), while it was increased significantly with the application of P fertilizer (TSP). This study improved our understanding and provided insights that would be useful to the farmers in their efforts to amend the soil with inorganic fertilizers in order to enhance plant growth and biological nitrogen fixation.
