Chemical treatment and storage of sorghum seeds produced in different management zones
Abstract: Precision Agriculture considers soil attributes and production aspects to define management zones. Although there is little information, it is likely that seeds produced in different management zones have different quality after chemical treatment and storage. The aim was to evaluate the physiological quality of sorghum seeds produced in different management zones, after chemical treatment and storage. The management zones were defined from interpolated maps of soil and vegetation attributes with the aid of the Smart Map - SMP plugin, in a Qgis environment. After harvest, the seeds were treated with Thiamethoxam, Imidacloprid + Thiodicarb, Fludioxonil + Metalaxyl-M and a control treatment (water). Then, they were stored for 0, 60 and 120 days. The seeds were evaluated for their quality through the following tests: moisture, germination, dry mass of seedlings, electrical conductivity, and accelerated aging. The design was completely randomized in a 4 × 3 factorial scheme, with the management zones being analyzed independently. Sorghum seed treatments with insecticides cause greater phytotoxicity during storage in both management zones, unlike the fungicide treatment. Sorghum seeds produced in high-management zones have high physiological quality and less deterioration during storage. Sorghum seeds produced in low-management zones treated with insecticides, as the storage time increases, show lower vigor due to deterioration and phytotoxicity.
期刊介绍:
From 2017 the Journal of Seed Science (JSS) will circulate online version only.
Original scientific studies and communications, not yet published or submitted to another journal for publication and written in Portuguese or English, will be accepted for publication. For manuscripts submitted in English, the authors should provide an adequated version.
The SCIENTIFIC COMMUNICATION is a category of scientific manuscript which describes a technique, an equipment, new species or observations and surveys of limited results. It has the same scientific rigor as the “Scientific Articles” and the same value as a publication. The classification of a manuscript as a SCIENTIFIC COMMUNICATION is based on its content and scientific merit but it can be a preliminary study, simple and not definitive on a certain subject, with publication justified by its uniqueness and contribution to the area.
The Editorial Board of the JSS may invite leading authors of recognized reputation to compose specific Review Articles covering topics of their specialization that will convey to the scientific community the state-of-the-art knowledge related to the specific theme.
