Or T9 . It indicates that when the CPE value reaches 5 cm, then the crop has to be irrigated. In the case of sowing sole okra and rice, the flat sowing approach was followed. 2.5. Crop Establishment Crops have been raised with common agronomy practices in raised and sunken beds. Rice (variety–IET 4786) seedlings were raised by wet bed approach and transplanted around the 1st week of February when the age in the seedlings was 45 days. Okra (variety–Hybrid Syngenta 152) was sown 1 week just before the transplanting of rice. Straight row planting at 2 cm depth was done for rice at a spacing of 20 cm 15 cm, taking 3 seedlings hill-1 with the assist of a rope marker in all the sunken beds. The rice seedlings have been planted inside the North-South path. Okra seeds had been sown around the raised bed at a spacing of 50 cm 50 cm. Gap filling in rice and thinning in okra was performed to obtain optimum plant population in the field. A suggested dose of 120 kg N, 60 kg P, and 60 kg K for 1 ha was applied to the sunken bed rice crop in the course of each the year of experimentation. 25 of N, complete doses of P, and half of K had been applied as basal during final land preparation. The first best dressing of 50 N at 25 days after transplanting (DAT) and the second best dressing of remaining 25 of N and half K was carried out at 55 DAT. In the raised bed, N:P:K dose for okra was 120:60:100 kg ha-1 . 25 of N, 50 of P, and 50 K have been applied as basal immediately after layout preparation. The first best dressing of 50 N, 50 P, and 50 K was accomplished at 25 days following sowing (DAS) as well as the second leading dressing of remaining 25 of N was produced at 45 DAS. For effective manage of weeds in sunken bed plots, Ambica paddy weeder (Ambica Engineering Works Pvt. Ltd., Talaja, India) was operated in between rows rice plants in both directions. Manual hand weeding was completed in the respective plots of raised okra bed. Plant protection measures had been taken at subsequent growth stages with Chlorpyriphos 20 EC at 2.five mL L-1 to manage yellow stem borer (Scirpophaga incertulas Walker) infestation inside the rice plots. Rice was harvested during the 2nd week of Could and plucking of okra fruits started from 3rd week of March and continued as much as the finish of May for both years. two.six. Wateruse, Productivity and Savings Water use by the rice crop was calculated utilizing the formula offered by Singh et al. [6] and Pereira [15]: Total water use by crop (ET) = Irrigation water supplied (I) + Productive rainfall received (ER) + Capillary rise (C) + Water contribution in the soil profile (SW). The level of irrigation water applied in every sunken bed rice plot starting from transplanting to maturity of crop was determined volumetrically, and also the total amount of applied irrigation water was worked out from the number of irrigation multiplied by the depth of irrigation. The measurement of effective rainfall was carried out by the balance sheet strategy, i.e., effective rainfall (ER) = Total rainfall (P)-Runoff (R)-Evaporation (E)-Deep percolation (D). Rainfall-runoff and deep percolation losses of water from the field had been DNQX disodium salt web regarded as zero for the dry season of both the year of experimentation, and no evaporation loss VBIT-4 Autophagy occurred due to complete groundcover by the crop foliage during that period. The capillary rise was presumed to become negligible as a result of the reduce depth of the groundwater table (three m). Water productivity (Wp) was expressed in physical terms (kg m-3 ) following the formula offered by Kijne et al. [16]: Wp = Yield Water useIn the raised bed of okra plot, soil samples w.
