An experimental research was performed at cotton research station at Sirsa district, CCS Haryana Agricultural University, Hisar during kharif to evaluate the different spacing and dose of nitrogen influences on quality and nutrient quality of cotton. The experimentation was laid out in split plot design having 4 spacing in main plots and 4 nitrogen doses in sub plots with 3 replications. The soil of the research field was loamy sand in texture with low nitrogen status. The trial results revealed that the nitrogen content in plant as well as in seed was also not affected by plant spacing however, uptake of nitrogen in seed was maximum with 67.5 cm × 15 cm spacing while nitrogen uptake in plant and total uptake was maximum in 67.5 cm × 10 cm spacing. Nitrogen content in seed increased significantly with 100% RD of nitrogen over 75% RD of nitrogen which remained at par with further increase in nitrogen levels however, nitrogen content in plant did not differ significantly with different nitrogen rates. The uptake of nitrogen in seed and plant as well as total uptake increased significantly up to application of 125% RD of nitrogen. The available nitrogen in soil was higher in 67.5 cm × 30 cm spacing. However, no significant variation in available P and K in soil was attained in different spacing treatments. Similarly, available N in soil after harvest of crop differed significantly under nitrogen levels, but it had no significant effect on available P and K in soil. The quality characters like ginning out turn (GOT), fiber length, micronaire value, and seed index were not affected significantly by different crop geometry and nitrogen levels.
