The proposed method offers valuable insights into agronomic water use efficiency, facilitating the optimization of drip irrigation for both annual and perennial crops. While effective for intensively irrigated crops, the method does have limitations for smaller wetted areas and longer irrigation cycles, depending also upon a reasonable determination of the active root zone depth and the soil capillary length.

The effects on soil water–salt dynamics, growth parameters, IWUE and yield were assessed under different lateral spacings and irrigation treatments. The different treatments comprised two lateral spacings (45 and 60 cm) and four irrigation treatments (canal water, C; conjunctive use of canal and saline water in a 1:1 ratio, C&lt;sub&gt;1&lt;/sub&gt;S&lt;sub&gt;1&lt;/sub&gt;; in a 1:2 ratio, C&lt;sub&gt;1&lt;/sub&gt;S&lt;sub&gt;2&lt;/sub&gt;; and saline water, S). The results show that soil moisture content decreased vertically downwards and radially outwards in all treatments, whereas soil salinity increased and decreased with increasing radial distance and soil depth, respectively, throughout the soil profile irrespective of the lateral spacing and irrigation treatments. The maximum yield and IWUE were observed at 45-cm lateral spacing for treatment C, followed by C&lt;sub&gt;1&lt;/sub&gt;S&lt;sub&gt;1&lt;/sub&gt;, C&lt;sub&gt;1&lt;/sub&gt;S&lt;sub&gt;2&lt;/sub&gt; and S.

In recent years, participatory irrigation management (PIM) has gained momentum as a strategy to improve the performance of irrigation systems, increase water use efficiency and promote equitable water distribution. This approach involves the active involvement of farmers and other stakeholders in the planning, implementation and management of irrigation systems. The state of Bihar has primarily an agrarian economy and irrigation is essential for agricultural production. However, Bihar's irrigation potential is being underutilized due to improper management of irrigation systems. In Bihar, the experiment of PIM in the Paliganj distributary of the Sone irrigation scheme was attempted as a local initiative by WALMI Patna, which was funded by USAID, and, thus, the need for an overall state policy and strategic plan was realized. Therefore, PIM has been implemented through the formation of water users' associations (WUAs) and farmers’ organizations (FOs) at different levels under the Bihar Irrigation Act of 1997, and Bihar Irrigation, Flood Management and Drainage Rules, 2003. The Bihar model of PIM is based on the macro-to-micro approach because of its geographical conditions and the size of the schemes in the state.

In the present study, the DRASTIC (D, depth of water; R, net recharge; A, aquifer media; S, soil media; T, topography; I, impact of vadose zone; C, hydraulic conductivity) model was used to evaluate the groundwater sensitivity of the study area. To analyse Ho Chi Minh City's Upper-Middle Pleistocene aquifer vulnerability, the analytic hierarchy process (AHP) method was used to optimize the DRASTIC score and include land use (LU) characteristics. Four distinct weights were used: DRASTIC, modified DRASTIC-LU, AHP-DRASTIC and modified AHP-DRASTIC-LU. This study identified low, moderate and high vulnerability for 12%, 55% and 33% of the DRASTIC-LU index values, respectively. The AHP-DRASTIC index classifies 61%, 26% and 13% of sites as low, moderate and highly vulnerable, respectively. The study reveals that 52%, 30% and 18% of the area are vulnerable to the modified AHP-DRASTIC-LU index classes. The most sensitive factors are shallow aquifer roofs, recharge and LU.

Taking irrigation machine pipelines as the research object, a numerical simulation method is used to investigate the mixing and distribution patterns of water and fertilizer in pipelines under a steady oscillatory flow fertilization mode with different injection positions, angles, flow rates (<i>Q</i>) and fertilization ratios (<i>δ</i>). Increasing the flow rate initially increased the fertilizer concentration in the lateral pipes, but further increasing the mainline central injection flow rate significantly reduced the concentration in the lateral pipes. For <i>δ</i> = 2%, elevating <i>Q</i> from 6 to 8 m³/h increased the average fertilizer concentration in the lateral pipes by 0.4%. However, a subsequent increase to <i>Q</i> = 10 m³/h led to a 1% decrease.

In central injection, larger inclination angles increase the lateral pipe fertilizer concentration, while in left-side injection, 60°-downward injection results in the best lateral pipe fertilizer concentration.

This paper proposes a new irrigation scheduling scenario in which a sprinkler is used as the minimum optimization unit for sectoring design. The main challenge of the proposed approach lies in obtaining the most energy-efficient sectoring and pump operating frequencies, and the high complexity of the optimization problem requires considerable computational effort. To compare the irrigation performance before and after optimization, seven scheduling scenarios are established to analyse the performance of the unified control method, branch scheduling method and sprinkler scheduling method. Through numerical calculations and experimental verification, it was found that sprinkler scheduling can not only meet the pressure requirements of sprinklers without using pressure-regulating valves but also minimize energy consumption. Compared with optimal branch pipe scheduling, optimal sprinkler scheduling can reduce the sprinkler pressure variance from 792 to 180 kPa² and reduce the irrigation cost by approximately 18%.
