Description A field experiment was conducted during winter (rabi) season of 2011-2012 at Field Crop Physiology
Laboratory, Department of Agronomy, Chaudhary Charan Singh Haryana Agricultural University, Hisar, to study
the effect of irrigation levels and genotypes on barley (Hordeum vulgare L.). The experiment was laid out in
factorial RBD consisting of two irrigation levels, i.e., one irrigation at 40 days after sowing (DAS) and two
irrigations at 40 and 85 DAS and 21 genotypes viz., BH 05-20, BH 07-18 BH 08-05, BH 08-16, BH 08-18, BH 08-36, BH 09-05, BH 09-21, BH 09-37, BH 09-44, BH10-01, BH10-06, BH10-07, BH10-11, BH 10-22, BH10-35,
BH 393, BH 902 BH 927, BH 932, DWRUB 64 with three replications.
Irrigation and genotypes significantly influenced phenology, plant growth and water relations, yield
attributes, yields and malt quality except germinative energy. The interaction between genotypes and irrigation
levels/frequencies was also significant indicating differential behavior of barley genotypes at different irrigation
frequencies. Application of two irrigation delayed phenological events as compared to one irrigation. Application
of two irrigations improved plant growth parameters such as plant height, number of tillers and dry matter
accumulation, and leaf water potential and relative water content over application of one irrigation. Grain and
biological yield were higher under two irrigation than one irrigation. Malt quality characters such as bulk density,
bold grains and protein content were higher while husk content, thin grains and malt recovery was lower under two
than one irrigation.
Among barley genotypes, plant height higher in BH 09-21, number of tiller per meter row length in BH
08-36, dry matter accumulation in DWRUB 64, leaf area in BH 902, leaf water potential in BH 09-21, relative
water content in BH 05-20, number of spike per meter row length in BH 10-22, number of grains per spike in BH
10-06, test weight in BH 09-44, grain and biological yield in BH 902, bold grains in BH 10-11,bulk density in BH
10-35, protein in BH 10-07, malt recovery in BH 927 as compared to the remaining genotypes under study. The
interaction between irrigation and barley genotypes was also significant for most of the characters indicating
differential behaviour of barley genotypes to two irrigation levels.
