MetadataShow full item record
The harvest is a critical time in the production of the peanut (Arachis hypogaea L.), however in this operation losses are inevitable, in some cases o f up to 30% of production. Peanuts are grown for a short period during the reform of the sugarcane fields, providing better usage of the agricultural spaces in Jaboticabal, São Paulo. The objective of this research was to see how early the peanuts could be dug up once they are seen to have matured. The peanuts were dug up at 120, 125, 130, 135 and 140 days after sowing. Results were subjected to variance analysis by the F-test, and when there was significance of the averages, the Tukey test at 5% probability was applied, using a box plot for the following variables: maturation, moisture content of pods and soil, mechanical resistance of soil to penetration, harvest loss and productivity. The box plot proved efficient in the univariate evaluation of the analyzed variables, creating excellent conditions for viewing their behavior. Digging up the peanuts at 120 DAS is recommended.
