| dc.description.abstract | Water management strategies place a considerable priority on water conservation in areas with limited resources of water. Scheduling water applications can help farmers to manage their water in a way that is significantly better. The scheduling of water application deals with applying water at the right time and in the right quantity in order to optimize production and maximize water conservation. In the present study, decision making software DSSAT (Decision Supporting System for Agrotechnology Transfer) CROPGRO model has been employed for cabbage crop to simulate the growth and yield under different scheduling of water applications based on the maximum allowable depletion of available soil water in a sub- tropical humid region . The field experiments were conducted at the Vegetable Research Center (VRC) of G. B. Pant University of Agriculture &Technology, Pantnagar situated in Udham Singh Nagar District of Uttarakhand, India. The experiments were conducted on cabbage crop (Green Coronet) during 2020-2021 and 2021-2022. During the first trial the transplanting of the crop was done in October 2020 and harvested in the month of February, 2021and during the second trial, transplanting was done in November 2021 and harvested in February 2022. The soil profile moisture content of the experimental field was determined using the gravimetric method. The irrigation treatments during cabbage growing experiments consisted of irrigation scheduling based on maximum allowable depletion (MAD) of available soil water (ASW) criteria such as, T1 (15%) indicated that 15% maximum allowable depletion (MAD) of available soil water (ASW), T2 (30%), T3 (45%), T4 (60%) and T5 (75%). No water stress was maintained at the initial stages of the crop development in order to allow the plants to attain healthy growth. Field experiments showed that an irrigation schedule with 45% maximum allowable depletion of available soil water gives the maximum water use efficiency for cabbage crop. It was also found that the scheduling irrigation for cabbage crop, 0-30 cm soil profile to be considered as most of the water was to be found extracted from this layer by the plants. | |
