Analysis and correlation among agronomic and weather parameters in barley (Hordeum Vulgare L.) cultivars under Semi-Arid regions of Haryana, India

A study was carried out in 2016-17 and 2017-18 growing seasons with 4 different “barley” cultivars viz., V1-BH 393, V2-BH 902, V3-BH 946 and V4-BH 885 sown under different growing environments, i.e., D1- 3 rd November; D2- 18th November; D3- 3 rd December and D4- 19th 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. | Analysis and correlation among agronomic and weather parameters in barley (Hordeum Vulgare L.) cultivars under Semi-Arid regions of Haryana, India
