Efficient use of water through the use of SMART irrigation systems available provides a promising solution to address such a problem. Thus, a study utilizing a combined climate- based and soil moisture SMART irrigation system has been conducted to assess its effects on the growth of Robusta coffee seedlings compared to practiced manual irrigation. The experimental design utilized a Complete Block Design (CBD) approach. Additionally, water consumption was measured to determine any significant differences. Over the course of the two-month experiment, 20 replications per treatment, it was observed that coffee seedlings subjected to the automated irrigation system (T1) exhibited significant improvements in both plant height and number of leaves, with growth rates of 72.56% and 65.29%, respectively, compared to manually irrigated plants (T0). Although the water savings achieved under the automated system were not statistically significant, there was an 18.95% reduction in water consumption. These findings highlight the potential benefits of automating irrigation systems using an IoT approach, specifically in terms of enhancing coffee seedling productivity. By utilizing real-time data from sensors, the SMART irrigation system effectively optimized water usage and resulted in improved growth and yield.

Impact of climate change is expected to adversely impact the water resources. Therefore, finding new efficient, environmentally friendly, and affordable water-saving techniques in agronomy is a necessity for achieving agricultural sustainability. Irrigation water can be saved by creating capillary barriers (CB) to unsaturated moisture flow. In this study, a “nature-inspired capillary barrier design” called hereafter as Smart Capillary Barrier (SCB) (mosaic of fine textured blocks, made of silt loam, and sandy sheath surrounding the blocks) was tested in series of field experiments with soil columns and pots. We investigated the effect of the percentage of sand of the sheath on water storage capacity of the SCB blocks and growth of okra (<em>Abelmoschus esculentus L.</em>) under deficit irrigation. Three proportions of sand to silt loam (sand%:silt loam%) in the sheaths were used in this study, SCB-25 (25:75%), SCB-50 (50:50%) and SCB-75 (75:25%). Our results show that increasing the percentage of sand in the designed and constructed SCB composite reduces evaporative and drainage water losses and therefore increases the water storage capacity of the blocks. Our SCB-75 attains 1.7–1.3 smaller drying rate than that for SCB-25 and SCB-50, respectively. Therefore, this composite had higher water saving capacity than a homogeneous soil (no capillary barrier) and a soil with a standard sand mulch (coarse soil overlies fine soil). The study found that using SCB composite did not consistently have a clear effect on the growth of okra plants at all stages of their development. However, during the development stage, using SCB-75 resulted in significantly higher dry biomass of the plants compared to using a homogeneous soil (the control). Additionally, during the initial stage of fruit yield, using SCB-75 also resulted in significantly higher fruit yield compared to using a homogeneous soil.
