Background: In north China, wide-belt sowing (WBS) is widely used in wheat production because it increases the yield by improving the plant distribution and reducing the competition for resources compared with conventional narrow-drill sowing (NDS). Yield formation is also different for wheat varieties with distinct spike types. Therefore, it is important to explore the effects of WBS on the yields of wheat varieties with different spike types.

Drip fertigation (DF) has been widely adopted in wheat production in recent years and has effectively improved yields. However, the responses of the yield and quality to the N topdressing rate (NTR) under DF are still unclear.

The seed rate and the interaction between the sowing method and seed rate also affect yield formation. However, the effects of the sowing method and seed rate, as well as their interaction on biomass production, particularly the interception of solar radiation (ISR) and radiation use efficiency (RUE), are unclear.
