The experiment aimed at identifying and selecting primer fertilizer formulas included 1 control formula: 40 kg N + 90 kg P2O5 + 60 kg K20 + 500 kg of powdered lime, 4 formulas of manure + control and 4 formulas of microbiological organic phosphate + The control was arranged in full randomized blocks and 3 repetitions, monitoring soil chemistry, growth and yield of peanut variety MD7. The results showed that the fertilizer formula influenced plant height from flowering to harvest, the number of leaves on the main stem, number and weight of nodules over time, the number of green leaves remaining when harvested, productivity, economic efficiency and indicators of soil agrochemical. The most suitable fertilizer formula is 1.4 tons of microbiological organic phosphate + control for 1 ha. However, the study recommends that the formula for fertilizing 1.1 tons of microbiological organic phosphate + control will yield the highest VCR ratio of 5.17 times. Adding microbiological organic phosphorus was more effective than equivalent formulas with manure.
