A split - plot experiment with four replicates on performance of dual purpose pearl millet (Pennisetum glaucum
L.) under different saline irrigation water was conducted during kharif 2015 at ICAR - CSSRI experimental farm,
Nain,Panipat. The experiment was conducted with 4 main - plot treatment consisting of different levels of saline
irrigation water [ Normal(~0.6 dS/m) and three levels of saline irrigation (ECiw 3, 6 and 9 dSm - 1)] and two sub - plot
treatments of varieties [ICMV - 15111 and AVKB - 19]. AVKB 19 variety was found robust and more stable than ICMV
15111 in terms of physiological attributes (relative water content, membrane injury, and chlorophyll content) at all three
periodic observations taken at 50 days after sowing (at1st cut), 30 days and 60 days after 1st cut. Among biochemical
attributes, total soluble sugars, proline, epicuticular wax content increased with increasing stress levels where as
protein content decreased with increasing level of salinity stress. AVKB 19 variety accumulated significantly higher
osmolyte content than ICMV 15111. Irrespective of salinity treatments Na+ content (shoot and root) was recorded
gradually high with ICMV 15111 than AVKB 19 at all study stages. AVKB 19 variety presented significantly higher
shoot and root K+ content than ICMV 15111. Data on green fodder yield showed significant differences between two
cultivars across different saline water levels. The AVKB - 19 variety produced significantly higher mean green fodder
yield (27.96 t/ha) as compared to ICMV - 15111(25.51 t/ha). The AVKB - 19 resulted into significantly maximum DM
yield at the 1st as well as in 2nd cut (5.67 and 5.09 t/ha) over ICMV - 15111. AVKB - 19 variety produced significantly
higher (16.26%) grain yield of 1.93 t/ha as compared to 1.66 t/ha in ICMV - 15111. The magnitude of reduction (%)
with increasing salinity over good quality irrigation water was observed 10.14, 20.74 and 37.33 with 3.0, 6.0 and
9.0 dS/m salinity water, respectively. Our results concluded that AVKB - 19 variety of pearl millet proved superior
and may be adapted as a choice for getting higher grain as well as green fodder yield with better physiological and
biochemical responses under saline environment. (Exceeding 250 word limit)
