A field experiment was conducted under rainfed conditions, on a shallow soil (Inceptisol) underlain with weathered basalt and on a deep soil (Vertisol) to evaluate three cotton cultivars [AKH 4 ( Gossypium arboreum ), LRK 516 ( G. hirsutum ) and NHH 44 (intra- hirsutum hybrid)] under four levels of N (0, 40, 80 and 120 kg ha −1 ) and to analyse the variations in productivity using the nitrogen use efficiency (NUE) parameter. The yield of AKH4 and NHH 44 was 101 and 89% higher than that of LRK 516. The yield and the response to N were higher on the Inceptisol. The enhanced yield and NUE of AKH 4 and NHH 44 were attributed to the improved efficiency of N uptake utilization. NUE declined from 21.6 at 40 kg ha −1 to 7.7 at 120 kg N ha −1 . The N uptake efficiency and N utilization efficiency were independent of each other, but complemented each other in improving NUE. The implications of variations in NUE, N uptake efficiency and N utilization efficiency and their components, N biomass production efficiency and HI, in cotton breeding and agronomy are also discussed.
