The lint harvest index (HI) of cotton is the ratio yield to total aboveground biomass cotton, which not yet clear in arid-zone areas. In 2022–2023, large-scale sampling was carried out Xinjiang, and HI different variety types Xinjiang their key drivers were clarified using methods such as random forest modeling (RFM) structural equation (SEM). results show that overall ranged from 0.276 0.333 0.279 0.328 for Xinluzao (XLzao) types, Xinluzhong (XLzhong) types. SEM analysis latitude (−0.99) planting density (0.50), climatic geography factors, available potassium soil (0.88), nutrient have greatest effects on Xinjiang. driving factors found be among This study aimed clarify explore its factors. undertaken order provide a theoretical basis accurate estimation straw yields arid zone.

Due to the labor shortage, replacing manual topping with chemical has become an important practice in cotton-producing areas such as Xinjiang, China. Similarly, increasing planting density is a common strategy enhance cotton yields. This study aimed quantify interactive effects of and on growth assimilate partitioning. To achieve this, two-year (2020–2021) field experiment was conducted The main plots were assigned low (15 plants m−2) or high plant (25 m−2), subplots using heavy amounts mepiquat chloride (MC) topping. dynamics dry matter accumulation partitioning well quantified beta-growth function overall nRMSE 11.5%. Results indicated that increased aboveground maximum by 4.88%, fruit 17.9% seed yield 14.0% compared At density, index between vegetative reproductive organs showed no significant differences. However, at time when 50% for 2.6 physiological days (under optimal temperature conditions) delayed than topping, resulting 2.7 delay fruits reached rate. results suggest applying chemicals little earlier high-density could reduce negative boll promote carbon growth.
