Objective: Soils in Burkina Faso are mostly characterized by their poverty in organic matter and nutrients. Several sources of organic matter were studied in Burkina Faso, but few scientific results are available on the use of neem (Azadirachtaindica). The current study was initiated to evaluate the effect of neemseed cake (NSC) on lowland rice productivity. The experimental design was a randomized blocks design established in Manzourin 2017. Treatments were: T0: control; T1: Recommendation/200 kg.ha-1 NPK + 100 kg / ha urea; T2:5 t.ha-1 NSC + 200 kg / ha NPK; T3:5 t.ha-1 NSC +100 kg / ha urea; T4: (5 t.ha-1 NSC + 200 kg / ha NPK + 100 kg / ha urea). The results showed ahighestnumber of tillers (22 tillers) and paddy yields (7.45 t.ha-1) for T4 treatment (5 t.ha-1 NSC + 200 kg / ha NPK + 100 kg / ha urea) compared to other treatments. TreatmentsT1 and T3 recorded comparable paddy yields (respectively 5.91 and 5.77 t. ha-1). The NSC combined with mineral fertilizers (NPK and / or urea) can significantly increase rice productivity inthe lowlands.
