    Appraisal of aquacrop model for barley crop production under semi-arid conditions in Haryana
    (CCSHAU, Hisar, 2023-05) Bassi, Navreet; Surender Singh
    Barley is one of the most important cereals of the world. It is cultivated in almost all parts of the world except the tropical regions. Barley is a major source of food for larger number of people living in the cooler semi-arid regions of the world where wheat and other cereals are less adapted. The present study entitled “Appraisal of AquaCrop Model for barley crop production under semi-arid conditions in Haryana” was conducted in Research farm of Department of Agricultural Meteorology, CCS HAU, Hisar for two seasons 2019-20 and 2020-21. Barley crop was sown in four different dates: 15th November 2019 and 28th November 2020 (D1), 30th November 2019 and 14th December 2020 (D2), 15th December 2019 and 28th December 2020 (D3) and 30th December 2019 and 8th January 2021 (D4). Four cultivars selected for the study were BH 393 (V1), BH 902 (V2), BH 393 (V3) and BH 885 (V4). The objectives of the experiment were, (i) To evaluate AquaCrop model for barley crop for semi arid conditions in Haryana, (ii) To estimate barley crop water productivity (CWP) in different growing environments, and (iii) To compare yield response of barley crop in different growing environments. During the experiment, observations were recorded for plant growth parameters, soil moisture content at various depths (15, 30, 60 and 90 cm), soil temperature at 15 and 30 cm depth, micrometeorological parameters and yield and yield attributes. The AquaCrop was evaluated using the observed parameters recorded during the two-season experiment. From the experiment it was concluded that, the AquaCrop model overestimated the grain yield of varieties BH 902, BH 946, BH 885 and underestimated the yield of BH 393. The model showed a closer estimate with the crop sown in November than in crop sown in second fortnight of December or later. After the evaluation of the model it was concluded that AquaCrop can effectively work for the semi-arid conditions of Haryana for November sown crop. The CWP was observed to be higher inseason 2020-21 than season 2019-20. November sown crop showed a higher CWP than December and January sown crop. BH 885 showed the maximum CWP than other varieties. November sown crop showed a higher yield and plant growth parameters than December and January sown crop and BH 885 showed a higher yield and plant growth parameters.
