In order to achieve success in the production process of a crop, it is necessary to use nutrients properly for plant growth and development. The aim of this study was to assess the efficiency of seed and foliar application of commercial products (Calcium + Boron; Cobalt + Molybdenum) to peanut crops at different application times. The experiment consisted of the following treatments: T1- Application of (Co+Mo) and (Ca+B) to the seeds; T2- Application of (Co+Mo) and (Ca+B) to the seeds, plus foliar spraying of (Ca+B), (17 DAS) of the seedlings; T3- Application of (Co+Mo) and (Ca+B) to the seeds, plus foliar spraying with (Ca+B), (23 DAS); T4- Application of (Co+Mo) and (Ca+B) on the seeds, plus foliar spraying of (Ca+B), (29 DAS); T5- Application of (Co+Mo) and (Ca+B) on the seeds, plus foliar spraying of (Ca+B), (35 DAS); T6 - Application of (Co+Mo) and (Ca+B) on the seeds, plus foliar spraying of (Ca+B), (41 DAS) T7- Absolute control. Seed application of (Co+Mo) and foliar application of (Ca+B) led to a greater gain in green plant mass and greater pod weight when applied at 23 DAS.
