In this study, pot experiments with three different nitrogen level treatments under conventional irrigation and MNBI were conducted to investigate the effects of MNBI and nitrogen application levels on rice yield, nitrogen accumulation and utilization. The results showed that MNBI promoted rice yields by increasing the seed setting rate compared to conventional irrigation, and nitrogen accumulation was positively correlated with nitrogen application but significantly increased by MNBI due to the increased root growth and activity. Furthermore, the activity of key enzymes involved in nitrogen metabolism, nitrate reductase and glutamine synthetase, significantly increased under MNBI at a nitrogen level of 225 kg ha−1. In conclusion, with the elevation of nitrogen application, MNBI improved rice yields and nitrogen accumulation and utilization, indicating that nitrogen and MNBI synergistically enhanced rice yields. Thus, the results provide the basis for efficient and high‐yielding super rice cultivation.","PeriodicalId":92799,"journal":{"name":"Irrigation and drainage (International Commission on Irrigation and Drainage)","volume":"40 4","pages":"138 - 147"},"PeriodicalIF":0.0,"publicationDate":"2022-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50997326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the average Mn, Fe, Cu and Zn values in the drained water were less than the input water. The effect of watering on heavy metal concentration of the drainage water was statistically significant. Temporal analysis showed increasing trends for the heavy metals from T1 to T5. In the case of T1, after the third irrigation programme, Zn, Mn and Fe concentrations were reduced. Based on Pearson's correlation coefficients, Mn, Fe, Cu and Zn in drainage waters had significant positive correlation with each other. Also, the treatments had significant effects on heavy metal concentrations in potato shoots and tubers (except Zn in tubers). Based on heavy metal accumulation in drainage waters, potato shoots and tubers, the treated watering order was T1 > T3 > T2 > T4 > T5 (except Fe in shoots). The heavy metal concentration in tubers was less than in shoots. Cu and Zn accumulation in potato was within standard limits.

In Benin for instance, schemes in Zonmon and Bamè (Ouémé Valley) were abandoned upon withdrawal of the project developers and have been sub‐optimally used ever since, while the neighbouring scheme of Koussin‐Lélé (Zou Valley) is still functional (double rice cropping) and well operated and maintained by the farmers. The factors for success and failure were investigated by comparing the two abandoned schemes with the successful one, using field observations and stakeholder surveys. We observed that (i) operation and maintenance costs associated with irrigation were presumably lower in the successful scheme––where irrigation was driven by gravity––compared to the failed ones––where part of the schemes were designed for motor‐pump driven irrigation. Moreover, contrary to the situation in the unsuccessful schemes, farmers in the successful scheme of Koussin‐Lélé benefit from (ii) external technical support, (iii) a favourable land tenure policy, entailing seasonal redistribution of plots favouring active and motivated producers, (iv) reliable access to credit, and (v) an effective farmer organization. These observations underscore the importance of addressing the longer‐term technical and financial needs of the beneficiaries for the successful development of irrigation schemes advancing smallholder farmers in sub‐Saharan Africa.

In this study, performance of a participatory irrigation management system is compared with that of a conventional centrally controlled irrigation system. The study is carried out for canal irrigation systems of Lower Chenab and Jhelum, both located in Punjab, Pakistan. The performance indicators used included: establishment cost, operation and maintenance cost, water fees (abiana) collected and equity of water distribution. The data for performance assessment were collected from various sources, including field measurements, interviews with farmers, interviews with officers of the irrigation department, previous studies, and data from the Punjab Irrigation Department and the Punjab Irrigation and Drainage Authority. The analysis indicates that establishment costs of both public–private partnership management and a centrally controlled irrigation system are more than operational and maintenance costs. The water supply in the main canal is satisfactory in both systems. Water fees (abiana) collected are declining in the case of the participatory management system. Structural change in the participatory management system and extensive work on capacity building are required in order to obtain the benefits of transferring management to farmers' organizations in Pakistan.

For this reason, a study was undertaken in order to determine monthly irrigation requirements for three study sites, for both vegetables and sugarcane. A proper scientific methodology was applied to achieve this information on crop water requirements in Jamaica for the first time. In addition, the cumulative frequencies of monthly and seasonal rainfall depths were analyzed, and this information used to develop monthly rainfall values, as well as seasonal rainfall values for different return periods for the sites. Each study site was found to be unique in its irrigation requirements, which highlights the climatic and soil variability across the island. However, all three sites were similar in their need for irrigation during the months of March and April for vegetables, signifying that this is a universally dry period across the island. This information is meant to provide a foundation for irrigation planning and water management strategies during water‐scarce conditions.

This two‐part review aims to advance understanding of the historical and present role of traditional irrigation farming schemes in Europe. It confirms that, prior to the industrial era, irrigation had been an essential part of farming for centuries. It was practised in very different, often contrasting, environmental regions across Europe. The historical spread of the schemes is presented in a map. Two ‘golden ages’ of traditional irrigation in Europe can be identified: the first in the High Middle Ages along with the introduction and widespread adoption of the three‐field system, and the second in the late eighteenth up to the first half of the twentieth century with reorganization of this agricultural system. Due to the complex character of past irrigation functioning, scientific understanding of processes and long‐term impacts is difficult, but ultimately all irrigation farming enterprises were driven by the purpose of increasing yields. Apparently the traditional schemes were the result of an evolution process over the course of centuries characterized by steady optimization and adaptation to historic and local conditions.
