SUMMARY
The present study was carried out in the Department of Soil Science, CCS HAU, Hisar during kharif season in screen house. The experiments were conducted on a sandy soil having initial pH (1:2) 8.21 and ESP 7.88. Soil of different ESP (15, 30 and 45) was prepared. Observed ESP was 7.88, 13.86, 31.15 and 43.79, respectively. The first experiment was conducted in screen house to study the effect of different ESP levels (control, 15, 30 and 45) on pearl millet (HC-20) with fixed 80 kgN/ha dose. In second experiment different Nitrogen levels, 0, 40, 80, 120 kgN/ha on pearl millet at an ESP of 45 were studied. The results on the studies on different ESP levels, revealed that the dry matter yield, plant height, protein content and uptake of nutrients (N, P, K, Ca, Mg & S) decreased with increasing ESP levels. The uptake of micronutrients (Zn, Cu, Mn, & Fe) in pearl millet decreased with increasing ESP levels. However, the studies on different levels on different levels of Nitrogen at 45 ESP, revealed that the dry matter yield, plant height, protein content and uptake of nutrients, N, P, K, Ca, Mg, Na, S, Zn, Cu, Mn, & Fe by pearl millet increased with increasing Nitrogen levels
Key words: ESP, Nitrogen, nutrients uptake, dry matter yield, protein content, pearl millet
