- Abstract:
-
Two main local cotton cultivars were selected, to study yield, nitrogen use and water use efficiency difference of cotton varieties by different water and nitrogen. The results showed that: the hybrid A1 was better than Xinluzao 33 in overall performance, dry matter accumulation and cotton yield were no significant difference at the low water conditions (3 600 m3/hm2), middle and high water treatment (4 500 m3/hm2, 5 400 m3/hm2) were significantly different between varieties; the differences of nitrogen uptake and nitrogen use efficiency were significant in two nitrogen levels (240 kg/hm2, 320 kg/hm2) between varieties; low water level was not significant, middle water was significant under the two nitrogen, high water and low nitrogen was not significant, high water and high nitrogen was significant in water use efficiency between two cotton varieties.
