Researching on influence of fertilizer dose on growth development an yield of groundnut at Bac Giang in order to identify optimal feritlizer dose for good growth and high rain yield of groundnut on degraded soil. This study was conducted with two new groundnut varieties L14 and MD7. The experiment was replicated three in random complete block design (RCBD) to identify of growth development and yield. Testing results show that: fertilizer dose influences on growth development and yield. Fertilizer dose influences on duration, branch, leaf area index, dry matter accumulation, number of nodes, number of pods and grain yield. Optimum fertilizer dose for both two groundnut varieties: L14 and MD7 in spring season at Viet Yen - Bac Giang is 10 ton organic fertilizer + 500kg CaO + 30kg N + 90kg P2O5 + 60kg K2O/ha. Achieved the highest net income formula (10 ton organic fertilizer + 500kg CaO + 30kg N + 90kg P2O5 + 60kg K2O/ha) was 26,322,850 VND/ha for the same MD7 and 27,267,850VND/ha for the same L14.
