Abstract
Studies of adaptability, agronomic characterization and productive potential of peanuts, including information on morphophysiological characteristics, make it a strategy for choosing the best cultivar. In view of the above, the objective of this work was to verify the physiological characteristics and productivity of different peanut cultivars. In January of 2019 an experiment was installed in the Paulista Agribusiness Technology Agency, Regional Paulista Regional Camp, located in the municipality of Adamantina, state of São Paulo. The experimental design was in randomized blocks with six treatments, that is, peanut cultivars: Tatu, Semper Verde, OL3, OL5, 503 and 505 and with six replications totaling 36 plots, where each plot was composed of three plants. The Tatu cultivar showed low values of morphological characteristics and productivity compared to other cultivars. The cultivars OL3, OL5, 503 and 505 showed higher averages of productivity. Great genetic variability was observed among the cultivars evaluated in this research due to the results obtained in the physiological and productivity variables.
