“…Rice is the major crop of Punjab and because of high water demand of rice crop, groundwater level is declining at an alarming rate in the state, so it is important to undertake a study to access impact on groundwater recharge under different establishment method of rice. Direct seeding of rice in dry and wet condition is efficient method for water saving in terms of irrigation as well as more deep percolation of water which may ultimately contribute to groundwater recharge (Kumar et al 2015;Choudhary et al 2016). The studies on potential groundwater recharge through water balance and modeling for the direct seeded (DSR) and transplanted rice (TPR) are lacking.…”

The present study utilizes soil water balance and HYDRUS-1D for estimating and predicting potential recharge in groundwater declining region of central Punjab, respectively. A field experiment was conducted at Punjab Agricultural University, Ludhiana. Two treatments viz direct-seeded (DSR) and transplanted rice (TPR) with three replications, were sown/transplanted during kharif season of 2019. The amount of water applied through rainfall/irrigation was recorded and bottom flux was measured using frequency domain reflectometry (FDR) and then predicted using HYDRUS-1D in order to assess potential groundwater recharge which was further compared with deep percolation determined using soil water balance. The performance of the HYDRUS-1D was evaluated using RMSE, NSE, and R 2 and found to be performing well. The paired t-test (t = 1.28 and t = 1.30 for TPR and DSR, respectively) was found to be non-significant at P = 0.05 which showed the correspondence between predicted and estimated parameters. The percentage change between estimated and predicted potential groundwater recharge was found to be 0.7% and 2.32% in TPR and DSR, respectively. The study revealed that there was 9% water saving and 14.6% more deep percolation (cumulative bottom flux) in DSR as compared to TPR that may potentially contribute to groundwater recharge.

A field experiment was conducted in the Instructional Farm of the College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar, India during 2017-18 to study the effect of rice establishment methods on phenophases, productivity, and profitability in rice- rice system. The experiment in kharif was laid out in a randomized block design with 3 treatments viz. direct seeded rice (DSR), non-puddled transplanting (NPTR), and puddled transplanting (PTR) with 3 replications whereas, in Rabi, these 3 establishment methods were reassigned within each treatment leading to 9 treatment combinations. Two promising rice varieties, cv. Swarna sub 1 and cv. Lalat were adopted in this experiment during kharif and rabi, respectively. Rabi rice under DSR-DSR matured 8 days earlier than PTR-PTR method, whereas the maximum grain yield (6.65 t ha-1) was recorded under the NPTR-PTR with the maximum harvest index of 0.52 which was 30.5% higher than DSR-DSR.The highest system yield (11.45 t ha-1) was recorded under the NPTR-PTR method of establishment which was 27.2% higher than the DSR-DSR method of establishment. The NPTR-PTR rice establishment also recorded the highest system gross return of Rs.1,79,785/- ha-1, the net return of Rs. 93,475/- ha-1, and B-C ratio of 2.1 against the total cost of cultivation of Rs. 86,310/- ha-1. Thus, the NPTR-PTR method of the establishment was found to be the best method so far as productivity and profitability are concerned.
