A rapid screening (hydroponic) and field testing programme There is increasing interest in improving the nitrogen (N) use efficiency of cultivated crops, due to the high cost of synthetic N fertiliser. Since existing differences in N use efficiency between sugarcane varieties could be exploited to improve N fertilisation, a hydroponic pot experiment was conducted to test the performance of seven commercial South African varieties (NCo376, N12, N14, N16, N19, N24, N25) at three N concentrations…

NITROGEN RESPONSES AND NITROGEN USE EFFICIENCY OF FOUR SUGARCANE VARIETIES IN MPUMALANGA
Nitrogen recommendations for sugarcane are currently based largely on responses of variety NCo376 in the various bioclimatic regions of the industry, together with an estimate of the nitrogen (N)
Nitrogen use efficiency of sugarcane (Saccharum spp.) varieties under in vitro conditions with varied N supply
TLDR
There was an indication that the distribution of NO3−-N between shoots and roots might affect NUE since varieties with a high in vitro NUE stored less NO3+-N in roots (compared with shoots) or exhibited better translocation of NO2-N from roots to shoots than those with low NUE.
The effect of form and level of inorganic N on nitrogen use efficiency of sugarcane grown in pots
ABSTRACT To-date, assessments of nitrogen use efficiency (NUE) of sugarcane have not included the contribution of its components, nitrogen uptake efficiency (NUpE) and nitrogen utilization efficiency
TO IMPROVE NITROGEN USE EFFICIENCY OF SUGARCANE IN THE SOUTH AFRICAN SUGAR INDUSTRY By
THE NITROGEN requirement of sugarcane in South Africa has been the subject of extensive research. Results of more than 200 trials conducted over the past four decades have shown that the response to
Variations in Growth Performance and Nitrogen Uptake of Sugarcane Cultivars Under Rain-Fed Conditions
TLDR
NiF3 and Ni27 could be introduced as the promising sugarcane varieties for better growth performance and high nitrogen uptake under rain-fed conditions because of positive associations between total nitrogen uptake with total biomass production and cane yield.
Inorganic nitrogen uptake kinetics of sugarcane (Saccharum spp.) varieties under in vitro conditions with varying N supply
TLDR
Assessment of the relative preference index (RPI) for NO3−-N and NH4-N uptake revealed that, at present, the RPI has no application in sugarcane due to its preferential uptake of NH4+-N.
Uptake of nitrogen, phosphorus and potassium by some promising mid late maturing sugarcane clones
A field experiment was conducted at the ECC farm of Sugarcane Breeding Institute, Coimbatore during 1999–2000 to evaluate promising mid late maturing sugarcane clones for nutrient use efficiency.
Effects of Pre Cutting Nitrogen Application Rate and Time on Seed Cane Quality of Sugarcane (Saccharum officinarum L.) Crop at Finchaa SugarEstate
Field experiment was conducted at Finchaa Sugar Estate during the 2010/11 cropping period to assess the effect of rate and time of pre-cutting nitrogen fertilization on seed cane quality of sugar
Integrated Effect Of Inorganic And Organic Fertilizers On The Yield Sustainability Of Plant And Ratoon Sugarcane (Saccharum Officinarum L)
Integrated nutrient management is an important tool in crop production. Inadequate or excessive fertilizer applications not only limit crop yield but deteriorate soil and environment.This study was
Nitrogen use efficiency and drought tolerant ability of various sugarcane varieties under drought stress at early growth stage
TLDR
The significant positive correlations among NUE traits and DTI suggested higher NUEs could support better a tolerant ability to drought stress at the early growth stage, and DTIs for aboveground and stalk dry weight could be used as the important DTIs to evaluate drought tolerant ability in sugarcane varieties.
