Cultivars under Semi-Arid Regions of Haryana, India Karan Chhabra*, Mahendra Bele, Raj Singh and Anil Kumar Department of Agricultural Meteorology, College of Agriculture (COA), CCS Haryana Agricultural University, Hisar-125004, Haryana, India *Corresponding author ABSTRACT Introduction Barley is the major source of food for large population of cool and semi-arid areas of the world, where wheat and other cereals are less adapted. Barley grain is a staple in Tibetan cuisine and was eaten widely by peasants in Medieval Europe. Grown on an area of 35 thousand hectares with a productivity of 3418 kg/ha (Agriharyana, 2017-18) is an important rabi crop in Haryana. Barley is a short growing season crop and has good drought and salinity tolerance. It is productive under adverse environments than other cereals. In International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 8 Number 05 (2019) Journal homepage: http://www.ijcmas.com A study was carried out in 2016-17 and 2017-18 growing seasons with 4 different “barley” cultivars viz., V 1 -BH 393, V 2 -BH 902, V 3 -BH 946 and V 4 -BH 885 sown under different growing environments, i.e., D 1 - 3 rd November; D 2 - 18 th November; D 3 - 3 rd December and D 4 - 19 th December. The correlations among growth, weather and agrometeorological parameters, yield and yield attributes, soil moisture and canopy temperature were investigated using correlation analysis during vegetative and reproductive phases of crop. Yield studies had positive association with growth parameters during both phases. All growth parameters had shown significant correlation during reproductive phase as compare to vegetative phase. The agrometeorological indices like GDD, HTU, PTU, RTD, and RUE were highly correlated during reproductive phase and HUE at vegetative phase with weather parameters. Maximum temperature, BSS and RH (M) had positive correlation while minimum temperature, RH (E), WS, PE and RF had a negative relationship with yield and its attributes except straw yield during reproductive phase. The association of growth parameters with agrometeorological indices and yield attributes with agrometeorological indices was higher at vegetative phase than reproductive phase. Canopy temperature was found significant relationship with soil moisture of depth 0-15 and 15-30 cm during both the barley crop seasons under different growing environments. It was concluded that these characteristics could be important selection criteria to quantify crop-weather relationships in barley crop under different growing environments.
