Responses of root growth and distribution of maize to nitrogen application patterns under partial root-zone irrigation
A field experiment was carried out to investigate the effects of varying nitrogen (N) supply andirrigation methods on the root growth and distribution of maize (Zea mays L.) in Wuwei,northwest China in 2011 and 2012. The irrigation treatments included alternate furrow irrigation(AI), fixed furrow irrigation (FI) and conventional furrow irrigation (CI). The N supply treatmentsincluded alternate ...
متن کاملYield and nitrogen leaching in maize field under different nitrogen rates and partial root drying irrigation
Irrigation water is limiting for crop production in arid and semi-arid areas. Furthermore, excess nitrogen (N) application is a source of groundwater contamination. Partial root drying irrigation (PRD) can be used as water saving technique and a controlling measure of groundwater N contamination. The objectives of this investigation were to evaluate the effect of ordinary furrow irrigation (OFI...

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...
effect of partial root-zone drying and deficit irrigation on yield and yield components of maize
an application of new irrigation methods to increase water use efficiency is essential, due to global water shortages, and as well a consumption of more than 70% of fresh water in the agricultural sector. in this study, the effect of full irrigation (fi), partial root-zone drying (prd) treatments at two levels (provision of 75% of et (prd75) and 55% of et (prd55)) vs. deficit irrigation treatme...
متن کاملEffect of Irrigation Timing on Root Zone Soil Temperature, Root Growth and Grain Yield and Chemical Composition in Corn
High air temperatures during the crop growing season can reduce harvestable yields in major agronomic crops worldwide. Repeated and prolonged high night air temperature stress may compromise plant growth and yield. Crop varieties with improved heat tolerance traits as well as crop management strategies at the farm scale are thus needed for climate change mitigation. Crop yield is especially sen...
