Nitrogen in the starter fertilizer is important to meet most of the early N needs of the corn crop if the bulk of the N required is to be applied in a sidedress application. Normal starter rates are usually adequate to meet this need. Starter N rate may be safely increased if you want to apply more of the total N at planting.
However, the rate. The Effect of Nitrogen and Phosphorus Fertilization on Growth, Yield and Quality of Forage Maize (Zea mays L.) Article in Journal of Agronomy 5(3). The objective of this study was to determine the effect of nitrogen (N) top-dressing on the number of total spikelet (fertile plus sterile) production and evaluate the effect among rice cultivars.

Specific recommendations for variable rate nitrogen (VRN) fertilization in corn (Zea mays L.) are required to realize the potential environmental and economic benefits of this technology.
However, recommendations based on algorithms that consider the processes controlling crop response to nitrogen fertilizer (NF) within fields have not yet been by: A Study and Economic Appraisal of the Effect of Nitrogen Fertilization and Selected Varieties on the Production and Processing of Sugar Beets.
HUGH G. ROUNDS, GEORGE. RUSH, DONALD grain, and corn with no nitrogen fertilizer applied to the corn crop. During the previolls season the corn showed extreme. Corn silage with high nitrate levels can be toxic to animals (Heininger et al.).
Consequently, it is imperative to determine an optimal level of nitrate fertilizer application that maximizes economic returns and results in a healthy plant nitrate content (Seungdo et al.
Conflict also exists as to how nitrogen fertilizer should be applied. Nitrogen fertilization has significant impact on horticultural crops with remarkable effects on harvested fruit quality, quality retention, and shelf life.
Recent research on plant nutritional effects on vegetable quality is also intensified. Low nitrogen levels usually result in reduced protein content and inferior quality by: 8.
The effect of nitrogen rate and cultivar on tobacco growth, yield, and leaf quality was investigated. Five burley cultivars were used in this study: TN 90, KTNCNC 7, and Clay’s All cultivar treatments received kg N ha-1 as a pre-plant broadcast application.
Additional nitrogen fertilizer was side-dressed 30 days after.

Starter K seldom increases corn early growth, except with less than optimum soil-test K. Corn responses to starter N occur less often than for P, and happen mainly when the primary N rate is not applied pre-plant in spring, with no-tillage, and in continuous corn.
The increasing use of the high yield potential of wheat has implicated in a more frequent use of agricultural supplies, among which nitrogen fertilization is shown to be important in defining the grain yield. Several authors reported a positive response of nitrogen fertilization on the grain yield of wheat [4, 5, 6].Author: Marcelo Carvalho Minhoto Teixeira Filho, Fernando ShintateGalindo, Salatiér Buzetti, Eduardo Henriqu.
Winter rye (Secale cereale L.) cover crop (RCC) has potential to reduce NO 3 –N loss from corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] r, RCC effects on annual crop productivity and corn optimal N fertilization requirement are unclear. The objectives were to evaluate corn and soybean yield response to RCC and corn optimal N rate.
Nitrogen rates determined from the online CNRC are directly the total fertilization amounts for each rotation, with no need to further adjust rate for previous crop.
That is, for the soybean-corn rotation, there is no need to subtract a "soybean credit as the rotation effect is already accounted for by the N rate trials that the database is.
analysis results, we have found that both fertilization and the effect of irrigation were significant on yield results. The correlation of year and examined cultivation technology elements or factors were also reliable. In the average of years, the yield increasing effect of fertilization differed reliably in irrigated treatments.
The analysis of variance (Table 5) for the three combinations (triticale alone, hairy vetch alone and association) and for the 5 doses of nitrogen showed a highly significant variation in the NDF content between the three combinations but did not show any apparent effect on nitrogen fertilization.
For example, triticale in monoculture had the Author: Salah BenYoussef, Salma S. Kachout, Sourour Abidi, Bilal Saddem, Jamila Ismail, Hichen B. Salem.

The effect of five increasing nitrogen rates (0, 10, 20 30 and 50 kg N ha-1) on the growth rate, the maximum dose of the test does not necessarily correspond to the level of “economic” nitrogen fertilization, which would make it possible to have the highest efficiency.
A similar result was reported by Hassen et : Salah BenYoussef, Salma S. Kachout, Sourour Abidi, Bilal Saddem, Jamila Ismail, Hichen B. Salem. Among all nutrients, nitrogen (N) is the most important and also the most limiting to crop production.
Efficient N use is important for the economic sustainability of cropping systems (Fageria and Baligar, ), and especially in vegetable production there is also a threat of negative environmental effects (Bavec and Bavec, ).
Most of the cultivated soils allow plants growth without addition of nutrients in mineral form. However, to seek higher production levels, the application of nutrients in mineral form is required, the current recommendation of nitrogen fertilization to define the amount to be applied.
For corn following corn, the reduction was from 12 to 23 lb N/acre. These are not large N rate changes, but sizeable enough to be considered for determining N rates as corn prices change.
Of course potential N rate changes depend on specific N and corn prices. The CNRC allows users to input whatever corn and N prices are applicable to their. Louisianas crop production industries are major contributors to the states economy.
The warm temperatures and high number of growing days combined with plenty of precipitation make many areas in Louisiana productive and suitable to grow a wide variety of crops for food, feeds, fiber, and biofuel feedstock production.
Soil testing remains an important best management practice. Nitrogen (N) fertilization is a key component to high corn grain yield and optimum economic return. It is a constituent of all proteins and enzymes in plant metabolism and integral part of chlorophyll (Brady, ).
Most agricultural soils are deficient in nitrogen for growth of crops, and this deficiency is overcome by the judicious. 42 EffEct of NitrogEN LEvELs oN graiN YiELd aNd somE attributEs of somE HYbrid maizE cuLtivars (Zea mays indentata sturt.) growN for siLagE as sEcoNd crop A.
