Effect of deficit irrigation and fertilization on cucumber
Soil water budgets are essential in determining the proper timing and amount of irrigation. Organic fertilizers can be substituted for commercial fertilizers; however, information is sparse on the interaction of irrigation management and nutrient source on cucumber (Cucumis sativus L.) production. This study evaluated nutrient source and irrigation management on growth and yield of cucumber grown ...

Potato response to a polymer-coated urea on an irrigated, coarse-textured soil
Controlled release fertilizers, especially polymer-coated urea (PCU), have been shown to reduce nitrate (NO3) leaching while maintaining potato (Solanum tuberosum L.) yields, but cost has been prohibitive. A new type of PCU (Environmentally Smart Nitrogen, Agrium, Inc., Calgary, AB) is less costly than previous PCUs, but its effectiveness on potato production has not been extensively studied. A ...

IDHA chelates as a micronutrient source for green bean and tomato in fertigation and hydroponics
The new biodegradable chelating agent imidodisuccinic acid (IDHA) has been studied for its application in agriculture. This study was conducted to compare the efficiency of mixed IDHA and ethylene diamine tetraacetic acid (EDTA) formulations to provide Fe, Mn, Zn, and Cu to green bean (Phaseolus vulgaris ‘Perfección negra polo’) and tomato (Lycopersicum esculentum Mill. ‘Shiren’) plants grown in ...

New methodical way for sustainable farming systems using treated sewage water in irrigation in Jordan
Most scientific approaches in research are done under objectified, controlled conditions. Such experiments do not reflect the everyday reality of farmers. Moreover, experimental research in agriculture does not always reflect the interests of Jordanian farmers. Another type of research is therefore needed. We need research that integrates Gamma and Beta sciences, farmers and scientists and the ...

Monitoring of Nitrate Leaching in Sandy Soils: Comparison of Three Methods
Abstract Proper N fertilizer and irrigation management can reduce nitrate leaching while maintaining crop yield, which is critical to enhance the sustainability of vegetable production on soils with poor water and nutrient-holding capacities. This study evaluated different methods to measure nitrate leaching in mulched drip-irrigated zucchini, pepper, and tomato production systems. Fertigation ...
