Abstract: The present study was undertaken to assess the production potential and quality of different pearlmillet accessions under saline environment. The experiment was conducted in Factorial RBD with treatments consisting 20 pearl millet accession and 2 cutting management. Irrespective of cutting management ICFH-15 recorded significantly highest value for total DM yield (15.3 t/ha), crude protein content (8.93%), EE (2.86%), ash content (10.08%) in fodder. Conversely to these aforesaid qualitative traits ICFH-15 recorded significantly lowest value for average NDF (64.20%) and ADF (35.50%) content. Two cuttings at 50 and 110 DAS resulted in maximum DM content (19.47%), Total Dry matter yield (12.16 t ha^-1), crude protein content (8.03%), and ADF content (37.56%), however the maximum Ether extract (3.06%) and NDF content (68.69%) observed under three cuttings each at 50,80 and 110 DAS treatment. The interaction between accessions and cutting management was found significant for total DM yield. In general, crude protein content and Ether extract decreased with advancement of crop maturity reverse to these traits DM, Ash, ADF and NDF content increased with maturity crop. The grain quality of accession ICFH-15 was recorded maximum crude protein content (10.43%); ether extract content (4.56%) and ash content (3.68%) than rest others. ICFH-15 resulted in lowest value of NDF (31.43%) and ADF content (3.12%). Concentrations of various macro and micro nutrients were estimated in grain. Among different accessions, ICFH -15 proved significantly superior with the maximum Ca (193.63 mg/kg), Mg (1208.13 mg/kg), Fe (68.82 mg/kg), Zn (74.67 mg/kg), Cu (9.19 mg/kg) and Mn (16.43 mg/kg) content in grains. Therefore, accession ICFH -15 and among cutting management strategies, single cut for green fodder followed by harvest for grain might be adapted for getting higher dry matter yield with better quality under saline environment.
