And three m for 1:3, 2:three, and three:3 ratios, respectively. A 00 cm soil layer was removed to create every sunken bed and deposited around the adjacent raised bed, generating the sunken beds 20 cm deeper than the raised bed. Final ploughing using a energy tiller in standing water was Seclidemstat Biological Activity carried out twice to produce the land effectively puddled, after which laddering was performed to get a uniform surface in sunken beds, and spading was accomplished within the raised beds to have a well-aerated and uniform surface. The entire experimental field was divided into three blocks, each and every of which contained 9 plots. Three irrigation channels have been provided along the ML-SA1 Autophagy length from the experimental field in involving rows of plots. The width with the irrigation channels were 1 m. An location possessing 1 m width was left as a buffer involving the sole plots. Rice was grown on the sunken beds irrespective of each of the therapies and okra was grown on raised broad beds of diverse breadth and widths with 20 cm elevation following the land configuration model (Figure three). The length of each plot in the RSB program was 6 m. The breadth of all of the sole plots for sunken bed was 3 m, and for the raised okra bed 3 distinctive bed widths of 1 m, 2 m, and three m have been taken as per the requirement. Land configuration was created in the 1st cropping season plus the layout was maintained as such for the following season as well.Agronomy 2021, 11,5 ofFigure 3.

Irrigation Technique Two irrigation schedules, namely I1 –continuous standing water (CSW) with standing water of 5 two cm depth and I2 –alternate wetting drying (AWD) at three 1 days interval for rice in sunken bed, had been taken for this study. Continuous standing water for rice was maintained up to the grain filling stage. Afterwards, the water level within the sunken bed was not maintained. Total numbers of irrigations for CSW in first and second year of study were 19 and 15, respectively, even though the numbers have been 12 and 9 for AWD in the course of 1st and 2nd year. Depth of irrigation water was 5 cm. 2.4. Treatment Details The field experiment was laid out in randomized block design and style (RBD) comprising nine treatment options with 3 replications. Therefore, there have been 27 plots inside the experiment. Each plot size for sunken bed rice was 6 m 3 m in size, and raised bed okra had varied plot sizes with distinctive bed widths of 1 m, 2 m, and 3 m plus a uniform length of 6m.The plot size for sole okra crop was 6 m 3 m. A buffer strip of 1 m was constructed to separate the sole plots each below CSW and AWD irrigation scheduling and also the sole rice AWD plot from the sole okra plot. Treatment specifics of raised and sunken bed (RSB) with irrigation scheduling are as follows: T1 –I1 RSB1 (1:3)–CSW in 3 m sunken rice bed with 1 m raised okra bed; T2 –I1 RSB2 (two:three)–CSW in 3 m sunken rice bed with two m raised okra bed; T3 –I1 RSB3 (three:3)–CSW in three m sunken rice bed with 3 m raised okra bed; T4 –I2 RSB1 (1:three)–AWD in three m sunken rice bed with 1 m raised okra bed; T5 –I2 RSB2 (2:3)–AWD in 3 m sunken rice bed with two m raised okra bed; T6 –I2 RSB3 (3:3)–AWD in three m sunken rice bed with 3 m raised okra bed; T7 –I1 Sole rice with CSW; T8 –I2 Sole rice with AWD and T9 –Sole okra (SO at IW/CPE ratio of 1.0). IW and CPE denote irrigation water and cumulative pan evaporation, respectively. IW/CPE ratio can be a climatological strategy for schedulingAgronomy 2021, 11,six ofirrigation.
