Rice is a major crop in the world and South Kivu. However, its cultivation still underdeveloped in our country, more than 200,000 tons of rice were imported in 2010.manystudies have shown that high yields can be produced in the province of South Kivu, which could contribute to the reduction of these imports. The use of fertilizers is one of the strategies for increasing rice production in the world. The experimental design used was the split plot with as main plot the variety (VO46 and FC56) and the secondary type of fertilizer (NPK, Manure, NPK-Manure and a control). The combination of these two factors gave us a total of 8 treatments including 6 from the combination of variety with fertilizers and 2 corresponding controls to variety grown without fertilization. These treatments were repeated three times. We proceeded to the germination and transplanting of 2 plantlet per planting hole at the spacing of 25x20 cm. The farm manure used at transplanting period (71gr / pouch) and 13g of NPK 17-17-17 or the NPK-Manure combination was hanged per pouch. The results showed that there are statistically significant differences between treatments (fertilizers) and between the varieties studied (P = 0.011). Control plots yielded an average yield lower than fertilized plots. In addition, the plots fertilized with NPK alone yielded a lower average yield (3.4 t / ha) than those of the other plots fertilized (5.4 t / ha) but higher than that of the control. The VO46 variety fertilized with the NPK-mixed organic fertilizer gave a significantly high yield (5.4 t / ha) compared to the FC56 variety (4.1 t / ha) fertilized with the same combination.

Abstract
Rice is a major crop in the world and South Kivu. However, its cultivation still underdeveloped in our country, more than 200,000 tons of rice were imported in 2010.manystudies have shown that high yields can be produced in the province of South Kivu, which could contribute to the reduction of these imports. The use of fertilizers is one of the strategies for increasing rice production in the world. The experimental design used was the split plot with as main plot the variety (VO46 and FC56) and the secondary type of fertilizer (NPK, Manure, NPK-Manure and a control). The combination of these two factors gave us a total of 8 treatments including 6 from the combination of variety with fertilizers and 2 corresponding controls to variety grown without fertilization.

Abstract: (french)
Le riz est une culture d’une importance capitale au monde et au Sud Kivu. Cependant, sa culture est encore sous développées dans notre pays, plus de 200.000 tonnes du riz blancs ont été importées en 2010, pour plusieurs études ont montré que des rendements élevés peuvent être produits dans la province du Sud Kivu, ce qui pourrait contribuer à la réduction de ces importations. L’utilisation de fertilisants est l’un de stratégie pour accroître la production du riz dans le monde. Le dispositif expérimental utilisé était le Factoriel bloc avec deux facteurs dont la variété (VO46 et FC56) et le fertilisant (Engrais) (NPK, Fumier, NPK-Fumier et un témoin). La combinaison de ce deux facteurs nous a donné un total de 8 traitements dont 6 issus de la combinaison de variété avec les fertilisants et 2 témoins correspondants à la variété cultivée sans fertilisation. Ces traitements étaient répétés trois fois. Nous avons procédé au germoir et au repiquage de 2 plantules par poquet aux écartements de 25x20cm. Le fumier de ferme utilisé épandu au repiquage (71gr/poquet) et 13gramme d’NPK 17-17-17 ou la combinaison NPK-Fumier était pendu par poquet. Les résultats ont montré qu’il existe des différences statistiquement significatives entre les traitements (fertilisants) et entre les variétés étudiée (P=0,011). Les parcelles témoins ont donné un rendement moyen inférieur à ceux des parcelles fertilisées. En plus les parcelles fertilisées avec NPK seul ont donné un rendement moyen inférieur (3.4 t/ha) à ceux des autres parcelles fertilisées (5.4 t/ha) mais supérieur à celui du témoin. La variété Vo46 fertilisée avec l’engrais organique mélangé au NPK a donné un rendement (5,4 t/ha) significativement élevé par rapport à la variété Fc56 (4,1 t/ha) fertilise avec la même combinaison.
