Abstract
A field experiment entitled “Relative performance of barley (Hordeum vulgare L.) cultivars under
different date of sowing” was conducted during rabi 2013-14 at Wheat and Barley Research Area of
CCS Haryana Agricultural University, Hisar. The experiment was laid out in a split plot design with
five date of sowing (30
th
October, 10
th
, 20th, 30th November and 10
th
December) in main plots and four
cultivars (BH 902, RD 2552, RD 2668 and DWRUB 52) kept in sub plots replicated thrice.
Based on the research investigation it was found that growth parameter of barley viz, plant height, dry
matter, LAI and number of tillers decreased significantly with delay in sowing .Crop sown on 30
th
October produced significantly higher values of growth parameters but it was statistically at par with
10
th
November sowing date. Yield attributes, yield and quality parameters (Grain protein content,
hectoliter weight and bold grain percentage) were reduced significantly as the sowing was delayed
from 10
th
November to 10
th
December. While, reverse trend was observed in thin grain percentage and
malt content of barley cultivars. Date of sowing fails to influence harvest and attraction index of barley
cultivars.
Among the various barley cultivars, RD2552 took significantly less number of days to all phenophases
(except emergence) as compared to other cultivars. Significantly taller plants and higher dry matter
accumulation at all the crop growth stages were recorded in cultivar BH 902 followed by RD 2552.
Maximum number of tillers was recorded in cultivar DWRUB 52 and LAI in cultivar BH 902 at all the
stages of crop growth. Barley cultivar DWRUB 52 being at par with BH 902 produced significantly
longer spikes, test weight and grain yield than other cultivars (RD 2552 and RD 2668). Cultivar BH
902 produced higher number of grains per spike, straw and biological yield which was significantly
higher from other cultivars except RD 2552. Barley cultivar DWRUB 52 recorded significantly higher
value of harvest and attraction index as compared to other cultivars.
Barley cultivars RD 2552 and DWRUB 52 showed superiority in protein content as compared to other
two cultivars (BH 902 and RD 2668). Cultivar DWRUB 52 recorded significantly higher hectoliter
weight of barley as compared to other three cultivars (BH 902, RD2552 and RD 2668). Maximum bold
grains percentage was found in cultivar BH 902 and it was significantly higher as compared to other
cultivars except DWRUB 52, while, thin grain percentage was recorded highest in cultivar RD 2552.
