Sow seeds at a spacing of 3.3 cm between plants and rows, cover the seeds with about 3 cm of soil, and transplant at a spacing of about 10 cm between plants and rows.

After emergence in 3 days, the daytime temperature should be lowered to...

Clever methods of using growth regulators to promote the recovery of sesame
During the flowering and capsule-setting stage of sesame, vegetative growth and reproductive growth proceed together, and the following key points should be mastered in field management. Reasonable topdressing: topdressing at the flowering stage can promote flower bud differentiation in sesame. Methods such as broadcasting nitrogen fertilizer and foliar spraying of phosphorus-potassium fertilizer and boron fertilizer can be used. For fields with good soil fertility retention and supply capacity, applying urea once at the early flowering stage is sufficient,...
