Effects of Nitrogen Forms on Carbon and Nitrogen Accumulation in Tomato Seedling
Agricultural Sciences in China, 2008Abstract Utilization of organic nitrogen (N) is an important aspect of plant N assimilation and has potential application in sustainable agriculture. The aim of this study was to investigate the plant growth, C and N accumulation in leaves and roots of tomato seedlings in response to inorganic (NH4+-N, NO3−-N) and organic nitrogen (Gly-N).

Plant Nitrogen Accumulation Dynamics in Rice in Response to Nitrogen Management
Communications in Soil Science and Plant Analysis, 2010This study investigates the effect of rice nitrogen (N) management on the dynamics of plant nitrogen accumulation (PNA) during internodal elongation (IE) in relation to grain yield. Four field experiments were conducted in two soils with six preflood N treatments. The PNA was monitored for 3 weeks, starting at the beginning of IE (BIE).

Nitrogen Accumulation and Residual Effects of Nitrogen Catch Crops
Acta Agriculturae Scandinavica, 1991The nitrogen accumulation in Italian ryegrass (Lolium multiflorum Lam.), perennial ryegrass (Lolium perenne L.), white mustard (Sinapis alba L.) and tansy phacelia (Phacelia tanacetifolia L.), unde...

Nitrogen Accumulation in Successions
1974Nitrogen in ecosystems has been determined as a function of time of plant succession in the entire ecosystem, in its biomass, and in its soil alone.

Nitrogen Accumulation in Soybean Following Defoliation
Journal of Plant Nutrition, 2009ABSTRACT The effects of defoliation on soybean [Glycine max (L.) Merr.] growth and yield have been well studied, but relatively little is known about its nitrogen (N) accumulation after defoliation. An experiment was conducted to examine soybean recovery and N accumulation following defoliation. The indeterminate cultivar (‘Tousan 69’) was planted in a

Nitrogen Accumulation Rates of Irrigated Maize
Agronomy Journal, 1983AbstractImproved fertilizer nitrogen (N) use efficiency in irrigated maize (Zea mays L.) often results from delaying application of moderate N rates until the crop is rapidly growing. The objective of this experiment was to determine how N application time, N rate, and planting date influenced the pattern of N and fertilizer−derived N (FN) accumulation

An understanding the relationships between N-fertilization rate, crop-N recovery, residual inorganic N in soil and crop yield can assist in making N fertilizer recommendations which balance crop value and environmental risk. Nitrogen was applied to three plantings of broccoli at 0, 125, 250, 375, 500 and 625 kg N ha−1 as a broadcast application of ...

Relationships Between Soil Nitrogen Availability Indices, Yield, and Nitrogen Accumulation of Wheat
Soil Science Society of America Journal, 2002The success of variable rate N fertilizer application rests on our ability to predict the contribution of soil N to growing crops. We assessed relationships between soil N availability indices (SNAIs), yield, and total N accumulation of wheat ( Triticum aestivum L.) grown in a typical glacial

Nitrogen (N) accumulation and its partition in a canola (Brassica napus L. ssp. oleifera var. annua) crop growing under different N availabilities were evaluated. Spring canola (cultivar Printol) plants were grown with 0, 30, 60, 90, 120, or 150 kg N ha− 1 applied at sowing.

Seasonal accumulation and partitioning of nitrogen by lentil
Plant and Soil, 1994Although wheat (Triticum aestivum L.) is the dominant crop of the semi-arid plains of Canada and the western United States, lentil (Lens culinaris Medik.) has become an important alternative crop. Sources and seasonal accumulation of N must be understood in order to identify parameters that can lead to increased N2-fixing activity and yield. Inoculated
