Corn yield and fertilizer N recovery in water-table-controlled corn–rye-grass systems
Concern about NO− 3 leaching and groundwater pollution from corn monoculture has prompted an investigation of alternative production systems that reduce leaching. It is hypothesized that both intercropping and water-table control could increase N uptake and reduce the quantity of N that might be lost due to leaching. This study compared corn (Zea mays L.) with annual Italian rye-grass (Lolium m...
متن کاملEffect of Different Amounts of Nitrogen Fertilizer on Grain Yield of Forage Corn Cultivars in Isfahan
To evaluate the effect of nitrogen fertilizer amounts on grain yield of forage corn in 2012, a pilot was implemented in Islamic Azad University Agricultural Research Station, Isfahan, as a split plot in a randomized complete block design. Main plots consisted of four levels: control (no fertilization ) , 50 , 100 and 150 kg per ha nitrogen from urea source and subplots , including several varie...

متن کاملUnderstanding N timing in corn yield and fertilizer N recovery: An insight from an isotopic labeled-N determination
Early fertilizer nitrogen (N) application on cover crops or their residues during the off-season is a practice adopted in Brazil subtropical conditions under no-tillage corn (Zea mays L.) systems. However, the effect of early N application on yield, plant N content, and N recovery efficiency (NRE) for corn is not yet well documented. Five fertilizer N timings in an oat-corn system were evaluate...
متن کاملThe Effect of N Fertilizer Placement on the Fate of Urea-15N and Yield of Winter Wheat in Southeast China
A field micro-plot experiment using nitrogen isotope (15N) labeling was conducted to determine the effects of placement methods (broadcast and band) and N rates (60, 150 and 240 kg ha-1) on the fate of urea-15N in the wheat-soil system in Guangde County of Anhui Province, China. N fertilizer applied in bands increased grain yield by 15% compared with broadcast application. The N fertilizer appl...
