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.

Flax is co.sidered to.be o.e o. the mo.t significant dual-purpo.e cro.s fo. o.l and fiber pro.uctio. in Egypt and *** have a substantial impact o. vario.s metabo.ic pro.esses,including increased pho.o.synthesis,endo.eno.s ho.mo.e levels,io. abso.ptio.,nucleic acid synthesis,and pro.ein *** facto.s co.lectively co.tribute to.the gro.th and develo.ment o. ***,this study aims to.investigate ho. three bio.ertilizers(Algae extract,CMS as a by-pro.uct o. yeast,and Metalo.ate multi minerals as amino.acids)can enhance bo.h the quantity and quality o. flax seed yield under sandy so.l *** field experiments were co.ducted at the Experimental Statio. o. natio.al Research Centre in nubaria District,Behira Go.erno.ate,Egypt during two.seaso.s(2021/2022)using a rando.ized co.plete blo.k design(RCBD).The results revealed significant differences amo.g all tested bio.ertilizers in terms o. vario.s characteristics studied in *** applicatio. o. algae extract at a rate o. 1.50 mL/L resulted in an increase in seed yield(to./ha)by 26.69%&19.89%,straw yield(to./ha)by 8.08%&17.12%,and o.l yield(kg/ha)by 47.72%&33.69%co.pared to.the co.tro. gro.p during bo.h seaso.s *** applicatio.s o. algae extract at a rate o. 1.50 mL/L alo.g with CMS at a rate o. 5 m L/L and amino.acids at a rate o. 1.50 mL/L demo.strated significantly higher macro.utrient co.tents(n,P,K),micro.utrient co.tents(Fe,Zn,Mn),seed o.l co.tent,and pro.ein co.tent in flax seeds during bo.h *** highest values fo. seed o.l co.tent and pro.ein co.tent%were o.tained thro.gh fo.iar applicatio. o. amino.acids at a rate o. 1.50 mL/*** can be co.cluded that fo.iar sprays with these bio.fertilizers effectively impro.ed flax perfo.mance by increasing seed straw and o.l yields,nutrients o.l,pro.ein and fatty acids seeds co.tents.
