Abstract:

Groundnut is an important food and cash crop in the BenishangulGumuz region of Ethiopia. However, inappropriate harvesting times constrain the seed quality of the crop. Therefore, field and laboratory experiments were conducted to evaluate the effect of harvesting time on seed quality of two groundnut varieties (Manipintar and Bulki). Analysis of field experiment data revealed that variety and harvesting time interacted to significantly (P < 0.05) influence all parameters studied except seed physical purity, moisture content, and vigor index. Both varieties had significantly higher seed quality parameters when harvested at their respective expected physiological maturity. At 14 days before expected physiological maturity, both varieties produced the lowest quality seeds. Generally, physical purity and seed moisture contents at all stages of harvesting except 21 days after the expected time of maturity as well as standard germination of both varieties harvested at or immediately before and after the expected times of maturity met the minimum national groundnut seed quality standard of Ethiopia. Seed health analysis revealed that eight fungal genera and two bacteria species were detected on seed samples harvested at different times. Manipintar was infected significantly higher than Bulki at all harvesting times except at the expected time of physiological maturity.
