The availability and cost of synthetic fertilizers do not adjust to the reality of the producer, adding to highly degraded and acid soils in the Peruvian Amazon as a result of activities such as intensive and migratory agriculture. A solution to this problem is the use of crotalaria (Crotalaria juncea), which allows the improvement and restoration of the soil. The objective of this research was to increase the yields of C. juncea, under different doses of fertilization from phosphorus and boron sources, such as the use of phosphoric rock and ulexite, evaluating agronomic variables and seed yield in the province of Lamas, San Martin. The design used was a DBCA of 3 blocks, 20 treatments (fertilization doses of phosphoric rock and ulexite), with 10 repetitions each. The variables evaluated were plant height, health percentage, weight of 1000 seeds, weight with shell and weight of dry seeds without shell. The results obtained indicate that T9 (phosphoric rock 103,68 kg/ha + ulexite 00 kg/ha), achieved the best results in all variables: plant height (132 cm), percentage of seed health (85,37%), weight of 1000 seeds (32,66 g), weight of shelled seeds (5800 g), dry weight of shelled seeds (3906,67 g), and yield (1562,67 kg/ha). In contrast, the control (T1) obtained the lowest averages in all the variables evaluated. In view of the results, it is concluded that the incorporation of phosphoric rock in this dosage has positive effects on the development and production of C. juncea plant seeds in acid soils.
