This study investigated the influence of soil texture, layering and water head on the soil water infiltration rate. It also selected the most accurate infiltration models to determine the water infiltration rate in homogeneous and heterogeneous soil profiles. Experiments were carried out in four soil containers with a length, width and height of 20 × 20 × 70 cm. Treatments consisted of two soil textures (sandy loam, SL; clay loam, CL), four soil profiles (homogeneous texture, SL and CL; and heterogeneous texture, lighter texture on the top, SL/CL, and heavier texture on the top CL/SL) and three water head sizes (4, 7 and 10 cm). Several models were used to determine the water infiltration rate under homogeneous (Kostiakov, modified Kostiakov, Philip, Horton, traditional Green–Ampt, modified Green–Ampt and HYDRUS-1D) and heterogeneous soils (traditional Green–Ampt, modified Green–Ampt and HYDRUS-1D). According to the results, the infiltration rate decreased over time and along the soil profile. Nevertheless, it jumped at the interface of two-layered soils when the heavier soil was in the bottom layer (SC treatments) due to the high potential of the second layer, and then it decreased. In the reverse layering, the infiltration rate in the interface was lowest (CS treatments) because of the higher hydraulic conductivity of the second layer. Additionally, the infiltration rate increased with increasing water head, but the rate of this increase was higher by changing the water head from 7 to 10 cm. The results of infiltration models showed that the accuracy of these models was higher in clay loam texture than in sandy loam texture. The modified Green–Ampt was the most accurate model in homogeneous and layered soils, with average RMSE of 0.0204 and 0.019, respectively. The Horton model had the weakest simulation in homogeneous soils, with an average RMSE of 0.1299. Additionally, the accuracy of HYDRUS-1D in layered soils was less than that in homogeneous soils (NS of 0.95 and 0.85, respectively), and its accuracy decreased with increasing water head in most treatments.</p>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"846-865"},"PeriodicalIF":1.6,"publicationDate":"2024-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139603227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in this study, pedotransfer functions were generated using multiple linear regression (MLR) models for the predictability of <i>K</i>_s in a Himalayan catchment in India. Fifty soil samples were collected and divided into two groups at a 70:30 ratio. Different soil attributes derived from 70% of samples were used for MLR generation, and attributes of the remaining 30% of samples were used for model validation. Six different MLR models constituting different independent soil attributes were generated and compared statistically. The results indicate that the MLR model comprising soil texture, bulk density, particle density, soil moisture content (MC), organic carbon content and porosity results in the highest adjusted coefficient of determination (<i>R</i>²; 0.93 and 0.89 during model generation and validation, respectively).

This study investigated the effect of plastic mulch on soil hydrothermal status and its consequent effect on potato production over 2 years in field experiments in Bogura, Bangladesh. We cultivated potato under four treatments: two coloured (black and blue) plastic mulches, strip tillage and no mulch. The black plastic mulch raised the soil temperature by 1.2–2.4°C in the early growth stages and by 0.4–1.2°C in the later growth stages compared to the no-mulch treatment. This mulch raised soil moisture by 5.1–15.9% and reduced weed growth by 91% compared to no mulch. The nitrogen, phosphorus and potassium contents of the soil were significantly higher under the mulching treatments compared to no mulch. When compared to the blue and no-mulch treatments, black mulch provided 31–34% and 45–48% more tuber yield of potato, respectively, which significantly improved the economic benefits under mulching treatments. Black plastic mulch is therefore suggested as a workable adaptation approach to increase potato production under limited water resources in northern Bangladesh and elsewhere with similar agroclimatic conditions.</p>","PeriodicalId":14848,"journal":{"name":"Irrigation and Drainage","volume":"73 3","pages":"895-909"},"PeriodicalIF":1.6,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139606223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cross-sectional data collected from 320 randomly selected smallholder farmers, considering the 2019/2020 production season, were used to analyse a one-step Cobb–Douglas stochastic frontier function. The results of the study revealed the existence of technical and allocative efficiency differences between gravity and fuel pump users. Factors that positively determine the level of technical efficiency scores are gender, age, education status, technology type and extension contact. Irrigation experience, access to credit, training and technology type positively affected allocative efficiency, while the distance to the irrigation water source had a negative effect. The findings have important implications for agricultural policy and practice as improving efficiency through the adoption of fuel-powered water-lifting technology could further improve overall agricultural productivity.

Station-controlled experiments provide a narrative of positive yield benefits from supplementary irrigation. In contrast, statistical evaluations of actual farm experience mostly show no yield benefit and lower profitability for supplementary irrigation adopters. To add evidence on this controversial practice, we evaluated data from 2012 and 2015 Bangladesh farm household surveys with causality econometric approaches that control for differences between supplementary irrigation adopter and non-adopter groups. After controlling for self-selection and endogeneity, we found no statistically significant yield benefit for supplementary irrigation.

Subsequently, both the treated effluents, treated textile effluent 1 (TTE1) and treated textile effluent 2 (TTE2), were used to cultivate spinach. The results indicated that irrigation with TTE1 and TTE2 resulted in ~9% higher spinach yields compared with the control. Moreover, the water use efficiency with the TTE1 and TTE2 treatments was ~1.2 times better than that with the control. The need for fertilizers in the case of spinach cultivation with treated effluents was compensated by the textile effluents as a result of the breakdown and mineralization of the effluent by immobilized <i>G. candidum</i>.
