“…However because of more vegetative growth causes delay in maturity i.e., it has taken more number of days to reach boll development stage at higher levels of nitrogen application. Similar results were reported by Howard et al, (2001), Dong et al, (2012) and Munir et al, (2015).…”

“…In previous studies (Milroy and Bange, 2004), N deficiency had been reported as a limiting factor for vegetative growth and fruiting. In some other studies it had been reported that higher level of N application cause more vegetative growth while shifting the balance between reproductive and vegetative growth phases and causing less fruiting (Howard et al, 2001). Sensitivity of cotton to N application is well established; excessive as well as lower N dose both may cause drastic effects causing higher vegetative growth, less fruiting, and ultimately lower seed cotton yield.…”

“…In earlier experiments Meredith et al (1997) also observed effect of N × genotypic interaction on NUE of cotton cultivars and they found lower N dose better as compared to higher N application. Higher N application is yield limiting factor in cotton due to shifting of plant balance towards more vegetative growth that delays maturity and lowers seed cotton yield (Howard et al, 2001). In present study we also observed highest NUE in cotton genotypes by lower N dose (50 kg N ha -1 ) as compared to higher level of N (150 kg N ha -1 ).…”

“…Environmental variations and drought has caused greater changes in genotype x year and/or genotype x location interactions of cotton (Islam et al, 2013;Gul et al, 2014). Even under favorable environment with higher nitrogen, the yield progress was not up to the mark (Howard et al, 2001). A shift in production technologies is required for sustainable yield improvement under both the conditions.…”

Nitrogen and moisture stress generally modify growth and development of cotton like several other field crops. Field experiments were conducted for two years to elucidate the interactive effect of moisture stress (I), nitrogen (N), and genotype (V) on agronomic traits, nitrogen use efficiency (NUE) and harvest index (HI) of cotton by using RCBD split-split plot experimental design. Four moisture stress treatments (I1: no stress, I2: moisture stress at inter-node elongation stage, I3: moisture stress at vegetative growth stage, and I4: moisture stress at inter-node elongation and vegetative growth stages), three nitrogen levels (50-N1, 100-N2, and 150 kg ha -1 -N3), and three genotypes of cotton (NIAB-846-V1, NIAB-824-V2, and CIM-496) were used in this study. Moisture stress, nitrogen, and cotton genotypic interaction exhibited significant effect on number of bolls per plant, leaf area duration (LAI), crop growth rate (CGR), net assimilation rate (NAI), NUE, and HI. In all genotypes of cotton, highest CGR, NAI, NUE, and HI was recorded where irrigation was applied at all growth stages (in no stress treatment) and moisture stress at vegetative growth stage (in treatment where irrigation was withheld at vegetative growth stage) with N dose of 50 kg ha -1 expect in few treatments where 150 kg N ha -1 exhibited greater crop growth rate. During 1 st year field experiment highest increase in HI of; NIAB-846 was 10.46% by I3×N1×V1, NIAB-824 was 80.62% by I3×N3×V2, and CIM-496 was 33.91% by I3×N3×V3. During 2 nd year, highest increase in HI was 31.60% in NIAB-846 (by I3×N3×V1), 20.98% in NIAB-824 (by I1×N1×V2), and 20.10% in CIM-496 (by I1×N2×V3). Nevertheless, highest NUE was achieved in no stress treatment but moisture stress at vegetative growth stage didn't significantly reduce harvest index and nitrogen use efficiency as compared to no stress (well water) treatment. Thus it may be concluded that moisture stress at vegetative growth stage in these cotton genotypes could be applied for saving of irrigation water and nitrogen fertilizer.

“…Further, Gerik et al (1994) reported that cotton deficiency caused reduction in the vegetative and reproductive growth in cotton crop. Moreover, Tewolde & Fernandez, (1997) and Howard et al (2001) reported the significant effect of nitrogen fertilizers on the reproductive development especially at bloom or at early boll fill. Another important aspect of N nutrition is its effect on fiber quality as well as on yield.…”

Agronomic practices significantly influence the productivity and quality of cotton plant. Present study was undertaken to evaluate the effect of nitrogen and sulfur fertilizer application on the fiber quality of cotton, during the year 2011/2012 and 2012/2013 under Mediterranean environmental conditions. All the treatments were laid in randomized complete block design in factorial arrangement each treatment were replicated thrice. Five rates of nitrogen (0, 60, 120, 180 and 240 kg ha -1 ) and five rates of sulfur (0, 15, 30, 45 and 60 kg ha -1 ) were involved in the experiments. Results of study indicated that increases in the rate of sulfur have negative impact on the quality of the cotton fiber and the highest rate of sulfur fertilizer gave the lowest fiber length compared with the other sulfur rates. On the other hand, the lowest uniformity ratio was observed by applications of sulfur at 30, 45 or 60 kg ha -1 . It was observed that application of sulfur had no significant effect on micronaire and fiber strength. Further, application of 60 to 120 kg N ha -1 have positive effect on the fiber length and caused 2.7 to 3.4% improvement in fiber lengths in 2012 compared to the treatment without N, while applications of nitrogen at 180 and 240 kg ha -1 did not provide an additional increase in fiber lengths. Further, it was reported that application of N significantly improved fiber strength, but these differences were not statistically different from the
