Abstract

There is no organized information for peanut about the characterization of environment production, as well as there are many doubts in terms of the factors that influencing the high yield. In order to identify which factors determining high yield and to start developing of the production environment for peanut, it was evaluated and harvested 45 commercial field during the growing season 2017/2018, 2018/2019 and 2019/2020 in Tupa city, Sao Paulo State. A methodology was developed to evaluate the pod yield (area from 1,8 to 2,42 hectare), as well as information of soil and weather were collected. The results could identify four levels of productivity (> 6200, 6200-5175, 5175-4125 and < 4125 kg ha-1) has changed the frequency according to the occurrence of water deficiency, which could diminish the pod yield around 23% in the growing season 2018/19. There was positive correlation between pod yield and rainfall (r=0,52), with soil organic matter (r=0,52), and negative correlation with late sowing date (r= -0,37). It could be concluded that the concept of production environment for peanut is dependent of other factors, such as; historic of field in terms of crop cultivated before and the soil organic matter.
