Research ArticleOpen accessPhrase in the titleA Fuzzy-GAs Model for Determining Varied Irrigation EfficiencyAnongrit Kangrang, Chavalit ChaleeraktrakoonIrrigation efficiency is necessary information in water resource management. We proposed fuzzy sets approach for estimating varied irrigation efficiency. Genetic algorithms technique was applied to calibrate membership function of fuzzy model. The fuzzy sets technique considered the uncertainty of the available water resource and required area as the input variables. The approach model was applied to determine the fluctuated irrigation … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 7,351 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSustainable Technology for Agriculture at Extreme Altitudes: Design and Evaluation of a Sprinkler Irrigation System in a Peruvian High Andean CommunityJuan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Daniel Olivier Carranza Lizana et al.In high-altitude agroecosystems, erratic rainfall patterns and steep topography severely constrain crop productivity by exposing plants to soil water deficits during critical phenological stages. This study aimed to enhance the productivity of eleven staple and horticultural crops corn (Zea mays), tomato (Solanum lycopersicum), cucumber (Cucumis sativus), eggplant (Solanum melongena), lettuce (Lactuca sativa), carrot (Daucus carota), barley (Hordeum vulgare), celery (Apium … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 2 Oct 2026 · 645 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReclamation of Irrigated Lands and Improvement of the Groundwater Regime Under Vertical Drainage OperationBalzhan Amanbayeva, Raushan Dzhaisambekova, Alexander Basmanov et al.The aim of the study was to identify patterns of seasonal groundwater-level fluctuations and assess the effectiveness of vertical drainage in regulating the reclamation regime of saline lands in Kazakhstan. The methods included monitoring-well observations, calculation of seasonal amplitudes, Student’s t-test, the Mann-Whitney U test, and Pearson correlation analysis. Before the growing season, groundwater occurred at a depth of 1.5-1.7 … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 23 Sep 2026 · 608 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnhanced Efficiency Potassium Fertilizer in Soybean and Cotton CropAdilson Pelá, Mário Miyazawa, Luciano G. Gil et al.Adequate plant nutrition is very important to soybean and cotton crops to express its potential production. Among plant nutrients, potassium (K) plays an important role in plants to achieve high yields. Potassium fertilization is an important tool for soybean and cotton high yields achieving because K absence reduces foliar K content and plant growth. Several strategies have been used to … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 13 Aug 2020 · 7,691 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy on the Suitable Irrigation Amount of Microporous Membrane Water-Fertilizer Integration of Tomato in Spring in Plastic GreenhouseXiao Huaijuan, Du Qingjie, Zhang Jiaxin et al.Water-saving irrigation is an important measure to alleviate the shortage of water resources in China. In this study, the growth, nutrient distribution, quality and yield of Tomato under different irrigation treatments are studied by using microporous membrane water-fertilizer integrated technology and the optimal irrigation water quantity under the condition of microporous membrane water-fertilizer integration was determined. The results show that … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 15 Jun 2020 · 7,403 accessesView PDF Cite
