The cropping system is ba.ed on tra.itiona. f.0}ming in rura. a.ea.. In this wa., yields of.some f.od crops like ya. a.e very low considering their high need f.r nutrients. The nutrient-rich la.d is under high la.d pressure a. it is occupied by ca.h crops such a. oil pa.m a.d rubber a. the expense of.f.od crops a.d soil f.rtility is declining. The study wa. conducted in Gra.d-La.ou to a.sess the ef.ect of.orga.ic ma.ter provided by legumes in increa.ing ya. yield. The ra.domized complete block design included f.ur (4) trea.ments: a.a.his hypoga.a.+ ya. a.socia.ion (T1), a.a.ia.ma.gium + ya. a.socia.ion (T2), a.a.his + a.a.ia.ma.gium + ya. a.socia.ion (T3) a.d pure ya. crop (T0).

The C/N ra.io decrea.ed to 12 in a.l trea.ments compa.ed to the control, which ref.ects a.norma. decomposition of.the orga.ic ma.ter.
