Abstract:

Lentil receival grade is highly dependent on grain quality, which then determines the export value and financial return for the grower. Grain quality can be affected by a number of factors including growing season conditions and environmental conditions post-maturity. Field research was undertaken to assess the impact of delayed harvest on seed quality of lentil crops in the medium rainfall zone of South Australia. The research was conducted from 2016-2017, at three sites. Seed quality assessments were undertaken for grain weight, screenings, seed coat colour, and wrinkle for three times of harvest. We found significant decreases in lentil harvest quality due to weathering as a result of delaying harvest time with some varietal differences. Generally, the smaller sized lentil varieties retained better quality characteristics compared to larger seed size varieties when harvest was delayed. In this study, rainfall was the most important factor in quality reduction. While the ability to withstand post-maturity weathering is present in some lentil varieties, timely harvest of lentil crops is necessary to ensure a successful and profitable lentil harvest.
