The researchers studied how hybrid cotton plants grow and absorb nutrients compared to regular cotton. They found that the hybrid cotton varieties accumulated more dry matter and took up more nitrogen, phosphorus, and potassium than the regular cotton. The leaves of the hybrid plants had higher amounts of nutrients, while the buds, flowers, and bolls also absorbed more nutrients in the late stages. Overall, the hybrid cotton varieties took up significantly more nutrients than the regular cotton, with Biaoza A1 and Xinluzao 43 accumulating 302.7 and 288.1 kg·hm-2 of N, 138.2 and 132.3 kg·hm-2 of P2O5, and 459.2 and 449.7 kg·hm-2 of K2O, respectively.
