Nitrogen (N) is the most limiting nutrient in cereal production, yet its use efficiency remains very low at only 35%. Nutrient (NUE) crucial for increasing crop yield and quality while reducing fertilizer inputs minimizing environmental damage. Optimum N rates that maximize without NUE have been found to vary from location location. This field study assessed effect of on spring wheat (Triticum ...

A large amount of nitrogen (N) fertilizer is required for paddy cultivation, but use efficiency (NUE) in farming low (20–40%). Much the unutilized N potentially degrades quality soil, water, and air disintegrates functions different ecosystems. It a great challenge to increase NUE sustain rice production meet food demand growing population. This review attempted find out promising management pr...

Crop breeding for high nitrogen use efficiency (NUE) or tolerance to low fertilization is thought be an ideal solution reduce the cost, carbon footprint, and other environmental problems caused by excess of fertilizers. As a model plant cereal crops, barley has many advantages, including good adaptability, short growth period, natural stress resistance tolerance. Therefore, research on improvin...

in order to increase grain yield, nitrogen use efficiency (nue) and nitrogen apparent recovery fraction (narf) in wheat (triticum aestivum l.), this experiment was carried out with 5 or 6 treatments and 3 or 4 replications in 14 locations at 22 different sites in iran during the 2004-05 growing season. the experiment was designed as a completely randomized block. the effect of n sources and tim...

conclusions this study on a limited number of patients treated with adjutant anthracyclins-based regimens, revealed that her2/neu is not a unique strong predictor for outcome, thus according to combination of her2/neu status and other clinical factors, it is necessary to distinguish patients at high risk of recurrence. results her2/neu amplification was identified in 19 (38%) of 50 patients. no...

The nitrogen use efficiency (NUE) is the ratio of N uptake by plant to total amount applied fertilizer. optimization NUE essential for sustainable agriculture, especially in breeding programs improve yield barley (Hordeum vulgare L.). We investigated variation 32 genotypes and examine response relationship between phenotypic traits level determine selection optimize NUE. was 2 yr under field co...

Potato (Solanum tuberosum L.) production on sandy soils requires added N. Only 40–60% of the applied N is acquired by crop. Increased use efficiency (NUE) and its components, utilization (NUtE) uptake (NUpE), could reduce fertilizer rates environmental losses. We compared in fresh-market red potato varieties, terms yield quality traits, examined potential mechanisms for that including uptake, u...

The Green revolution era has been the golden period for boosting food production specifically in South-Asia, but signs of fatigue late 1980s with a sharp decline factor productivity, stagnation crop yields dwindling and marginal farm incomes pose serious threat to security, agricultural sustainability, soil environmental health. In nutshell, growing concerns related health, productivity nutrien...

Abstract Grass nitrogen (N) concentrations of dairy grasslands are higher on peat soil than mineral soils. This can lead to increased N losses air and water from farming systems Our hypothesis was that the use low-N perennial ryegrass ( Lolium perenne L.) genotypes could be a means lower grass concentrations, when grown objective determine whether populations with different shoot tissue recorde...
