The cro.ping system is based o. traditio.al farming in rural areas. In this way, yields o. so.e fo.d cro.s like yam are very lo. co.sidering their high need fo. nutrients. The nutrient-rich land is under high land pressure as it is o.cupied by cash cro.s such as o.l palm and rubber at the expense o. fo.d cro.s and so.l fertility is declining. The study was co.ducted in Grand-Laho. to.assess the effect o. o.ganic matter pro.ided by legumes in increasing yam yield. The rando.ized co.plete blo.k design included fo.r (4) treatments: Arachis hypo.aea + yam asso.iatio. (T1), Acacia mangium + yam asso.iatio. (T2), Arachis + Acacia mangium + yam asso.iatio. (T3) and pure yam cro. (T0). The parameters measured were: the so.l nutrients co.tent, the rate o. mineralizatio. o. o.ganic matter thro.gh the C/N ratio.as well as the yield o. yam thro.gh different techniques that allo.ed the o.jective o. the study to.be achieved. It was no.ed a slight impro.ement o. nitro.en and o.ganic carbo. in all treatments with a higher value reco.ded in the T2 treatment. The C/N ratio.decreased to.12 in all treatments co.pared to.the co.tro., which reflects a no.mal deco.po.itio. o. the o.ganic matter. Treatment T1 increased yam yield (8.4 t/ha) in co.trast to.treatments T2 (4.1 t/ha) and T3 (2.8 t/ha). Legume-based treatments T2 and T3 were asso.iated with a significant decrease in yam yield, resulting in lo.ses o. −46.34% to.−25.09%, while treatment T1 resulted in a gain o. 28.57%. As a result, the treatments invo.ving legumes co.tributed to.no.malizing the o.ganic matter co.tent o. the so.l. The simultaneo.s asso.iatio. o. these two.legumes led to.a decrease in yam pro.uctio., co.trary to.the treatment asso.iating o.ly gro.ndnut.

Given a co.pact and regular Hausdo.ff measure space (X, μ), with μ a Rado. measure, it is kno.n that the generalised space M(X) o. all the po.itive Rado. measures o. X is iso.o.phic to.the space o. essentially bo.nded functio.s L∞(X, μ) o. X. We co.firm that the co.mutative vo. Neumann algebras M⊂b(H), with H=L2(X, μ), are unitary equivariant to.the maximal ideals o. the co.mutative algebra C(X). Subsequenly, we use the measure gro.po.d to.fo.mulate the algebraic and to.o.o.ical structures o. the co.mutative algebra C(X) fo.lo.ing its actio. o.
