Opportunities for Increased Nitrogen Use Efficiency in Wheat for Forage Use

Study of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics

In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...

growth and nitrogen use efficiency response of wheat and wild mustard to increased nitrogen levels

to investigate wheat and wild mustard growth and competition to n levels, an experiment was conducted in ramin agriculture and natural resources university of khouzestan, located at 36 km north of ahvaz. treatments included planting wheat solely, wild mustard solely, and intercropping wheat and wild mustard in pots. these combinations were exposed to n levels including 0, 60, 120 and 180 kg.ha-...

Deconvoluting nitrogen use efficiency in wheat: A simulation study

Cereal producers are under pressure to increase yields and maintain profitability against a background of environmental constraints and high ertiliser costs. The production of high yields requires high inputs of N, and excessive N can lead to pollution of watercourses. This provides an ncentive for the maximisation of nitrogen use efficiency (NUE), defined as grain yield per unit available soil...

Assessing Nitrogen Use Efficiency and Nitrogen Loss in a Forage-Based System Using a Modeling Approach

In intensive agriculture, N supply often exceeds crop requirements, even in nitrate vulnerable zones (NVZ). In farmland, the N surplus gives rise to NO3 ́ leaching and consequent groundwater pollution. The present study aimed at proposing measures to reduce N leaching and hence improve N efficiency in a buffalo livestock farm located in the NVZ of Latina plain (Central Italy). The farm was culti...
