“…The effect of a longer basin (200 m) impacts the operative cost reduction with a mild increase on distribution uniformity. This study showed that the size of the plots has a significant impact on irrigation development, namely that small-sized fields constrain the on-farm water distribution and the pathway to the irrigation automation to reduce labour requirements, a problem also discussed by Araujo et al [33]. The level basins or the graded borders with the lengths of 200 m allowed the highest IWP and EWPR, but these solutions require land reparcelling.…”

As surface irrigation systems are one of the most used water management techniques in the world, often working with high water losses, there is an urgency to their improvement. Modern methods that provide water savings and labour reduction require adequate design, management knowledge, and technical decision support. This study aims to improve water saving techniques for on-farm systems through an example of the decision-aid process being applied as a methodology based on the field experimentation and modelling of modern surface irrigation technologies in the Hetao (China) and Lower Mondego (Portugal) case studies. The performance indicators of irrigation water productivity (IWP) and the economic water productivity ratio (EWPR) were applied to compare the performance of several project solutions. The results obtained include a complete description of the latest irrigation solutions at the level basin, graded border, and graded furrows, which are adaptable to those case studies. The results revealed the benefits of a level-basin solution. For example, in Hetao, replacing the traditional system with a 100 m or 200 m long level basin, resulted in an increase in IWP by 40% and 3%, respectively, and in EWPR by 23% and 67%, respectively. The effect of a longer basin enables the reduction in operative costs, with a slight increase in distribution uniformity. In Lower Mondego, the IWP increased by 65% and the EWPR increased by 82%, by adopting graded furrows with 1.0‰ slopes and 200 m lengths. The main drivers of development of these surface irrigation systems were determined, namely, the runoff reuse and the system design and management. The issue that the local markets with equipment and consulting services should be available for farmers is also relevant to the development. It was proven that the effectiveness of modern surface water systems must adapt the solutions of the projects to the local characteristics of plot size and slope, soil type, and water supply.

“…The increase in discharge increased flow velocity and the furrow wetter perimeter and consequently increased soil losses. Araujo et al (2019) also reported that higher inflow rates caused larger losses of water and soil through runoff in furrow irrigation in the Curu‐Pentecoste irrigation scheme located in the state of Ceara, Brazil.…”

The suspension of eroded soil in surface runoff ultimately leads to the transfer of nutrients to land and water resources. Placing soil or straw (as a barrier) inside irrigated furrows in order to reduce water flow velocity, as a traditional local practice, has not been investigated from the environmental point of view. In this research, the effect of micro‐dams (barriers built inside the irrigated furrows, also known as tied ridges or furrow dikes) on the reduction of soil and phosphorus losses was investigated. Field experiments were performed in four consequent irrigation events. Two erosive inflow discharges (0.6 and 0.9 L/s) and two micro‐dam distances (10 and 20 m) were implemented as test treatments. A control treatment, without micro‐dams, was used for comparison purposes. For the discharge of 0.6 L/s, micro‐dams reduced furrow soil loss by 25% and 33% for distances of 20 and 10 m, respectively. For 0.9 L/s, soil loss was reduced by 25% and 59% for distances of 20 and 10 m, respectively. Micro‐dams also reduced dissolved phosphorus losses in runoff water by 13% to 37%, depending on discharge and distance, as compared to the control treatment. Micro‐dams can effectively reduce water, soil and phosphorus losses.

“…Lack of water resources, high water consumption, and inadequate flood irrigation have significantly reduced yield and quality. Furrow irrigation poses some important environmental problems; nutrient leaching, higher erosion (Seeda et al, 2020), and runoff in the experimental sites represented up to 70% of the applied water (ranging from 20 to 70%) (Araujo et al, 2019).…”

In Indonesia, corn is an important commodity that serves as the second source of carbohydrates after rice, whose productivity is influenced by management practices applied during cultivation. This research aimed to determine the effects of different management practices on the growth and yield of corn. This research was arranged in a single-factor Randomized Complete Block Design, with different agriculture management practices as treatments, consisting of TI1 = Best Practices (Drip Irrigation + Rice Husk + Mycorrhiza), TI2 = Farmers’ Practices (Furrow Irrigation) + Mycorrhiza, and TI3 = Farmers’ practices (Furrow Irrigation). The data observed were analyzed using Analysis of Variance and followed by the Post Hoc Tukey’s HSD at α= 5%. The results showed that the TI1 produced significantly higher plant height, stem diameter, leaf dry weight, weight of cob with cornhusk and kernel dry weight, and effectively suppressed weed growth compared to TI2 and TI3. TI1 produced a significantly higher number of leaves, root dry weight, and total dry weight compared to TI3, but not significantly different compared to TI2. TI1 produced not significantly different stem dry weight and harvest index compared to TI2 and TI3. The kernel dry weight per plant observed in TI1 was 157.63 g, which was 14.22% and 22.91% higher than in TI2 and TI3, respectively. Based on the coefficient correlation and path analysis, the number of leaves, plant height, and total dry weight should be considered as important plant growth variables to produce high kernel dry weight.
