| 1 | Optimization of equitable irrigation water delivery for a large-scale rice irrigation scheme显示文摘Equitable water allocation is essential in an irrigation scheme for obtaining potential crop yields from the entire scheme,especially when water supply is inadequate.An optimization model achieved this goal by coupling an optimal water allocation model with available water supply and irrigation water demand for a river-fed rice irrigation system in Malaysia.This model consists of a paddy field water balance module and an optimization module.The outputs from the module are daily irrigation demand and surface runoff,if there is any.The optimization module consists of an objective function,which minimizes water shortage across the scheme area while maintaining equity in water allocation.This model performs optimization subject to several system constraints,and the decision variable of the model is daily releases or supply to the tertiary canals.Performance of this model remained unaffected under different water supply conditions,and the optimization model reliably examined the effects of alternate water allocation and management rules with field information.It improves efficiency and equity in water allocation with respect to crop growth stages and water shortages rather than simply cutting irrigation supply on a proportional basis to overcome water shortages. | Md Rowshon Kamal Muhammad Iqbal Md Abdul Mojid Mohd Amin Mohd Soom Lai Sai Hin | 2018 | International Journal of Agricultural and Biological Engineering2018，11，5： | 3 |
| 2 | Leaf chlorophyll and nitrogen dynamics and their relationship to lowland rice yield for site-specific paddy management显示文摘The optimum rate and application timing of Nitrogen(N)fertilizer are crucial in achieving a high yield in rice cultivation;however,conventional laboratory testing of plant nutrients is time-consuming and expensive.To develop a site-specific spatial variable rate application method to overcome the limitations of traditional techniques,especially in fields under a double-cropping system,this study focused on the relationship between Soil Plant Analysis Development(SPAD)chlorophyll meter readings and N content in leaves during different growth stages to introduce the most suitable stage for assessment of crop N and prediction of rice yield.The SPAD readings and leaf N content were measured on the uppermost fully expanded leaf at panicle formation and booting stages.Grain yield was also measured at the end of the season.The analysis of variance,variogram,and kriging were calculated to determine the variability of attributes and their relationship,and finally,variability maps were created.Significant linear relationships were observed between attributes,with the same trends in different sampling dates;however,accuracy of semivariance estimation reduces with the growth stage.Results of the study also implied that there was a better relationship between rice leaf N content(R^2=0.93),as well as yield(R2=0.81),with SPAD readings at the panicle formation stage.Therefore,the SPAD-based evaluation of N status and prediction of rice yield is more reliable on this stage rather than at the booting stage.This study proved that the application of SPAD chlorophyll meter paves the way for real-time paddy N management and grain yield estimation.It can be reliably exploited in precision agriculture of paddy fields under double-cropping cultivation to understand and control spatial variations. | Asa Gholizadeh Mohammadmehdi Saberioon Lubos Boruvka Aimrun Wayayok Mohd Amin Mohd Soom | 2017 | Information Processing in Agriculture2017，4，4： | 3 |
