Or T9 . It indicates that when the CPE value reaches five cm
Or T9 . It indicates that when the CPE worth reaches 5 cm, then the crop have to be irrigated. Within the case of sowing sole okra and rice, the flat sowing process was followed. 2.five. Crop Establishment Crops have been raised with normal agronomy practices in raised and sunken beds. Rice (variety–IET 4786) seedlings had been raised by wet bed method and transplanted on the 1st week of February when the age in the seedlings was 45 days. Okra (variety–Hybrid Syngenta 152) was sown one particular week prior to the transplanting of rice. Straight row planting at two cm depth was completed for rice at a spacing of 20 cm 15 cm, taking three seedlings hill-1 with the enable of a rope marker in each of the sunken beds. The rice seedlings had been planted inside the North-South path. Okra seeds had been sown on the raised bed at a spacing of 50 cm 50 cm. Gap filling in rice and thinning in okra was carried out to acquire optimum plant population in the field. A advised dose of 120 kg N, 60 kg P, and 60 kg K for 1 ha was applied for the sunken bed rice crop through both the year of experimentation. 25 of N, full doses of P, and half of K had been applied as basal through final land preparation. The very first top dressing of 50 N at 25 days right after transplanting (DAT) and the second leading dressing of remaining 25 of N and half K was completed at 55 DAT. Inside the raised bed, N:P:K dose for okra was 120:60:one hundred kg ha-1 . 25 of N, 50 of P, and 50 K were applied as basal after layout preparation. The first major dressing of 50 N, 50 P, and 50 K was done at 25 days immediately after sowing (DAS) along with the second top rated dressing of remaining 25 of N was produced at 45 DAS. For helpful manage of weeds in sunken bed plots, Ambica paddy weeder (Ambica Engineering Performs Pvt. Ltd., Talaja, India) was operated between rows rice plants in both directions. Manual hand weeding was performed within the respective plots of raised okra bed. Plant protection measures have been taken at subsequent development stages with Chlorpyriphos 20 EC at 2.5 mL L-1 to handle yellow stem borer (Scirpophaga incertulas Walker) infestation in the rice plots. Rice was harvested during the 2nd week of May perhaps and plucking of okra fruits started from 3rd week of March and continued up to the end of May for each years. two.6. Wateruse, Productivity and Savings Water use by the rice crop was GS-626510 Biological Activity calculated employing the formula provided by Singh et al. [6] and Pereira [15]: Total water use by crop (ET) = Irrigation water supplied (I) + Effective rainfall received (ER) + Capillary rise (C) + Water contribution in the soil profile (SW). The amount of irrigation water applied in every single sunken bed rice plot beginning from transplanting to maturity of crop was determined volumetrically, and also the total amount of applied irrigation water was worked out from the variety of irrigation multiplied by the depth of irrigation. The measurement of efficient rainfall was carried out by the balance sheet system, i.e., effective rainfall (ER) = Total rainfall (P)-Runoff (R)-Evaporation (E)-Deep percolation (D). Rainfall-runoff and deep percolation losses of water in the field have been regarded zero for the dry season of each the year of experimentation, and no evaporation loss occurred as a consequence of full groundcover by the crop Bomedemstat Purity & Documentation foliage in the course of that period. The capillary rise was presumed to become negligible as a result of the decrease depth of your groundwater table (3 m). Water productivity (Wp) was expressed in physical terms (kg m-3 ) following the formula provided by Kijne et al. [16]: Wp = Yield Water useIn the raised bed of okra plot, soil samples w.
