“…The SWC is distributed within the root system, increasing water availability within the region of greater extraction according to the findings of Santos et al (2016). Root length density is more significant within the soil with mulch, mainly under drip irrigation (Jha et al, 2017;Santana Junior et al, 2020). Besides, mulching substantially reduces the evaporation, which results in a greater soil water content available for the plants (Damour et al, 2012;Anjos et al, 2017).…”

DMulching contributes to the maintenance of soil moisture at reasonable levels for crop growth. It influences the crop water demand and irrigation time. The aim of this study was to estimate evapotranspiration and root water uptake by the ‘BRS Princesa’ banana cultivar through a simple approach using some components of soil water balance within the root zone in bare and mulched soil irrigated by drip and micro sprinkler systems. The experimental design was completely randomized in split plots with six replicates. The plots consisted of two irrigation systems (drip and micro sprinkler), the subplots consisted of two soil surface conditions: with and without mulch. The alternative approach for soil water percolation in the soil water balance allowed obtaining ETc under field condition with reasonable accuracy. ETc estimated from the root zone water balance is lower than ETc from FAO Penman-Monteith equation. Root water extraction in the mulched soil under drip irrigation is higher than that under micro sprinkler irrigation.

“…In addition, drip and micro-sprinkler irrigation systems can re-distribute water and nutrient contents in the soil (Koumanov, Hopmans, & Schwankl, 2006). The use of one or the other can significantly influence root distribution, mainly when considering the flow rate and the number of emitters per plant (Santana Junior et al, 2020). Root distribution may also explain the growth and yield of the crop, while generating root indices for water irrigation management and solid or liquid fertilizer application.…”

“…Root distribution may also explain the growth and yield of the crop, while generating root indices for water irrigation management and solid or liquid fertilizer application. Studies on banana root distribution under irrigation conditions have been conducted (Sant'Ana, Coelho, Faria, Silva, & Donato, 2012;Santana Junior et al, 2020). However, most have evaluated roots that were influenced by irrigation systems.…”

This study evaluated the effects of fertigation, banana biomass as a soil covering under drip and micro-sprinkler irrigation system on the root growth and distribution and their relations with chemical soil attributes, soil water availability, and productivity. This work was conducted in a field with banana 2.5 × 2.0 m spacing and irrigated every two days using a drip and micro-sprinkler irrigation system during the first crop cycle. The experiment followed a random block design with six treatments, two irrigation systems, two fertilization methods of fertigation and side-dressing, as well as two cultivation types with and without soil covering. Roots were collected from each plot using soil monoliths and digitalization allowed the determination of root length density, and diameter at several distances from the plant and at different soil depths. Total root length, density, and distribution by diameter were evaluated based on the treatment interactions with respect to the distance from the plant and the soil depth. Our results showed that the combination of the irrigation system, fertilizer application and soil covering influenced root growth and distribution. In addition, we found that the better soil conditions for root growth were in drip or micro-sprinkler systems with fertigation and cultivated biomass covering.

Effects of Different Micro-Irrigation Methods on Water Use and the Economic Benefits of an Apple–Soybean Intercropping System

Intercropping systems reduce ineffective evaporation between trees but also intensify interspecific competition and reduce productivity. To improve the water-use efficiency and the economic benefits of an intercropping system on the Loess Plateau, China, where rainfall is limited and evaporation intense, an apple–soybean intercropping system with micro-irrigation water control was adopted to analyze the soil water, root density, water-use efficiency, yield, and economic benefits of intercropping under different micro-irrigation methods. Subsurface seepage irrigation, bubbler irrigation, and drip irrigation under mulching were used with irrigation upper limit levels of three maximum irrigation levels [60% (W1), 75% (W2), and 90% (W3) of field capacity (FC)]. Rainwater harvesting from ridges and furrows (GL) without irrigation was the control. Bubbler irrigation increased the soil water content, optimized the vertical soil water distribution, and promoted root growth. Except for the control treatment (GL), the other micro-irrigation treatments increased with the irrigation amount, but the water-use efficiency decreased. Drip irrigation under mulch combined with W2 (75% Fc) irrigation could obtain the maximum intercropping yield, which was increased by 71.1% compared with the GL treatment. Drip irrigation under a mulch combined with W2 produced the maximum intercropping yield; the economic benefits were higher under drip irrigation with mulching combined with W1; and all three micro-irrigation methods combined with W2 improved the economic benefits by 52.1–115.5% compared to GL. Drip irrigation under mulching or bubbler irrigation combined with W2 should be used when there are sufficient water resources, but drip irrigation under a mulch combined with W1 when there is a water shortage.
