Description
Summary:The indeterminate growth habit of peanut and characteristic underground fruiting make it difficult to identify the harvesting practices to achieve the highest yield and kernel quality. The objective of this work was to evaluate the effect of the digging dates and the subsequent stay in the field on the yield, lipid quality and health of the peanut kernels. The tests were carried out with cv. Granoleic during four seasons. The experimental design was completely randomized with three repetitions, with two digging moments (150 and 165 days from sowing) and in each of them four harvesting dates (7, 15, 21 and 28 days). According to the results, the delay in the digging dates increased the yield without kernel size and lipid fraction changes. On the other hand, increasing the number of days in the windrow did not improve these variables, but it did decrease the sanitary quality. Extending the crop cycle and the permanence of the pods in the field under the evaluated conditions did not improve the quality of the peanut kernel destined for human consumption.
