Selecting a suitable planting date is important for achieving high yield in cotton(Gossypium hirsutum L.), and is dependent upon cotton genotype. A two-year field experiment was conducted in Linqing, Shandong Province, to study the effects of cotton genotype and planting date on yield, yield components, photosynthetic rate and harvest index. A split-plot design with three replicates was used for the study. The main plots comprised two cotton genotypes(the early-developing variety SCRC21 and late-developing cultivar SCRC28), while planting dates(early planting, mid planting and late planting) constituted the subplots. A significant interaction affecting economic yield was detected between genotype and planting date, mainly attributable to variation in boll numbers·m-2 and lint percentage. For the early-developing cultivar SCRC21, plants sown in late April had the highest yield, 6.3% higher than those planted in mid-April; the yield was similar between plants sown in early and late April. For the late-developing cultivar SCRC28, plants sown in mid-April produced the highest cotton yield, which was 4.8% and 12% higher than for those planted in late April and early May, respectively. In the northwest of Shandong Province where film mulching is used, the early-developing variety is suitable for being delayed planted if no later than early May, and maximum yield can be obtained with being planted in late April. In terms of yield and economic index, the late-developing cultivar should be planted in mid-April, because later planting would significantly reduce cotton yield.
