Effects of salinity and irrigation water management on soil and tomato in drip irrigation
In this research, the effects of irrigation with saline and fresh water through drip irrigation method and using two irrigation management strategies: M1, M2 (M1 is irrigation with fresh water in alternative with saline water, M2 is saline water in first half time of each irrigation event and fresh water in the second half), on the yield, water productivity (WP), soil salinity, plant height...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Management Considerations for Operating a Subsurface Drip Irrigation (SDI) System
Gary A. Clark Research Agricultural Engineer Subsurface drip irrigation (SDI) systems deliver water to the root zone of crops using polyethylene drip tubing that is permanently buried below the soil surface. In properly designed and operated systems, little or no wetting of the soil surface occurs, nor is there visual evidence of the system performance. Because SDI systems apply water different...
متن کاملEffect of water stress on potato product in the drip irrigation (T-Tape)
Using modern irrigation methods such as border irrigation is one way for an optimum usage of water. Potato, for this study, was cultured in a farm located at Kermanshah faculty of agriculture to evaluate the efficiency of border irrigation. The culture potato was the Agria variety and the applied treatment were 50, 75, and 100 percent of potato plant`s water requirement. Tapes were 12 m and the...
متن کاملOptimizing Soil Moisture Uniformity and Irrigation Management
This research is a study on the relationship of irrigation water treatments and soil moisture distribution uniformity (DU). Soil moisture distribution was based on long-term data sets that were collected during wet and dry soil conditions (from permanent wilting point to field capacity) using a novel electromagnetic sensor-based platform moving inside subsurface horizontal access-tubes. The irr...
