  • Prevention of low-temperature damage to sesame seeds possible with 'non-woven fabric'

    Apr 4th, 2023

    The Rural Development Administration introduced a method of using non-woven fabrics that can stably grow rice without being damaged by low temperatures when sesame seeds are planted early. Sesame seeds, which were normally sown directly in the main field around May, are recently grown by growing seedlings around the end of April and transplanted to the main field. In this case, if the temperature drops during the planting season, the germination rate may decrease. After filling the box for growing sesame seedlings with soil and sowing the seeds, water enough so that the water penetrates to the bottom of the box. After that, cover the non-woven fabric with a thickness of 130 g / ㎡ or more and fix it so that it does not blow away in the wind so that the internal temperature of the non-woven fabric can be maintained. The non-woven fabric is covered for 2 to 3 days, then removed, and watered whenever the top soil dries to maintain moisture. Sesame is a tropical crop, so it is important to properly maintain the amount of water because constriction occurs in low temperature and high humidity conditions. Cut-off disease is a disease in which the lower part of the stem of young seedlings is infected and discolored to grayish brown and collapsed. When the Rural Development Administration used non-woven fabric to grow sesame seedlings, it confirmed the effect of an average temperature increase of 1.4 degrees in greenhouses and 3.0 degrees in open fields. The rate of sesame sprouts rising above the ground surface increased by 14.4 percentage points from 79.9% to 94.3% in the greenhouse. The number of days it takes for sprouts to come up has also been shortened by up to 2.3 days.
