“…Dasila et al . 11 showed that WUE in flooded irrigation conditions is very low, due to serious water and nutrient losses. A further complication is that an excess of soil water may not immediately exit the system, but may remain in the B horizon of texture-contrast soils as a perched water table 12 .…”

We studied the effects of soil matric potential and salinity on the water use (WU), water use efficiency (WUE) and yield response factor (Ky), for wheat (Triticum aestivum cv. Mahdavi) and bean (Phaseoulus vulgaris cv. COS16) in sandy loam and clay loam soils under greenhouse conditions. Results showed that aeration porosity is the predominant factor controlling WU, WUE, Ky and shoot biomass (Bs) at high soil water potentials. As matric potential was decreased, soil aeration improved, with Bs, WU and Ky reaching maximum value at −6 to −10 kPa, under all salinities. Wheat WUE remained almost unchanged by reduction of matric potential under low salinities (EC ≤ 8 dSm−1), but increased under higher salinities (EC ≥ 8 dSm−1), as did bean WUE at all salinities, as matric potential decreased to −33 kPa. Wheat WUE exceeds that of bean in both sandy loam and clay loam soils. WUE of both plants increased with higher shoot/root ratio and a high correlation coefficient exists between them. Results showed that salinity decreases all parameters, particularly at high potentials (h = −2 kPa), and amplifies the effects of waterlogging. Further, we observed a strong relationship between transpiration (T) and root respiration (Rr) for all experiments.

“…Nodulation parameters responded significantly only to main effect of irrigation frequency but not to main effect of intra row spacing and its interaction with irrigation frequency. All nodulation parameters were significantly increased with increase in irrigation frequency [ 3] which might be related to better availability of soil moisture with frequent irrigation [14].…”

Optimizing irrigation frequency and intra row spacing for specific environment is one the major agronomic practices to improve productivity of haricot bean. Hence, a field experiment was conducted to evaluate the effect of irrigation frequency and intra row spacing on growth, nodulation and agronomic performance of haricot bean at Arba Minch during dry season of 2018/19. The treatments consisted of three levels of irrigation frequency based on IW/CPE ratio (0.5, 0.67 and 1.0) with irrigation depth of 60 mm and three intra row spacing (6, 10 and 14 cm) which were factorially arranged in split plot design with three replications. Data were collected on phenological, nodulation, growth, yield and yield related parameters of the crop. The measured parameters were subjected to analysis of variance using SAS software version 9.0. Among the measured parameters, plant height, pod number per plant, dry matter and seed yield were significantly influenced by interaction effect of the treatments. The maximum seed yield (2873.7 kg ha −1 ) was recorded with interaction effect of irrigation at IW/CPE of 1 and intra row spacing of 10 cm. As for economic analysis, the same treatment combination also resulted in the highest net benefit (11254.1 Ethiopian Birr ha −1 ) and marginal rate of return (422.1%). Therefore, it could be concluded that irrigating haricot bean at IW/CPE ratio of 1 and planting at 10 cm intra row spacing could maximize both seed yield and economic benefit of the crop in the study area.

“…The ensuing rise in soil moisture during the haricot bean growth stages improved plant growth, which led to the subsequent increase in PH. Dasila et al (2017) also reported that increasing irrigation frequency maintains soil moisture availability and increases PH. Wube et al (2020) found that the treatment with no SI resulted in the minimum PH, while applying SI only at the emergence, pod formation and grain filling stages also resulted in low PH.…”

This study aimed to determine the impact of supplemental irrigation (SI) on the water use efficiency and yield of haricot beans during the growing seasons from 2020 to 2022. Six treatments were tested, including rain‐fed/no irrigation (T1), full irrigation throughout the season (T2), SI at vegetative, flowering and pod formation (T3), SI at emergence, vegetative and pod formation (T4), SI at emergence, flowering and grain filling (T5) and SI at emergence, pod formation and grain filling (T6), with three replications arranged in a randomized complete block design. The results showed that T2 significantly affected all growth and yield parameters except pod length and harvest index. However, T3 provided better water use efficiency and more acceptable yield reduction than T2. Thus, applying SI during the vegetative, flowering and pod formation phases proves to be more efficient for the production of haricot beans in the area under study as it leads to better economic returns and water productivity. In summary, irrigating the crop during the critical growth stages would result in water conservation and improved water productivity. Further research is recommended on SI to improve water use efficiency across different locations and seasons.
