Nitrogen dynamics in the intact grasses Poa trivialis and Panicum maximum receiving contrasting supplies of nitrogen.
The C(3) grass Poa trivialis and the C(4) grass Panicum maximum were grown in sand culture and received a complete nutrient solution with nitrogen supplied as 1.5 mol m(-3) NH(4)NO(3). (15)N tracer techniques were used to quantify the relative use of root uptake and mobilization in supplying nitrogen to growing leaves in intact plants which either continued to receive nitrogen or which received...
متن کاملA Calculation Tool for Analyzing Nitrogen Use Efficiency in Annual and Perennial Crops
Assessment of crop nitrogen use efficiency (NUE) is important in agricultural research. Various approaches exist to analyze NUE. A recently proposed NUE concept is further developed and a calculation tool for practical use presented. A critical component in the NUE concept is the plants’ mean nitrogen (N) content during the main growth period (N’). The N’ is delimited by the critical crop pheno...

The present study was undertaken to encourage the farmers to cultivate fodder grasses as an intercrop in the areca and coconut gardens. A live demonstration of fodder crops was under taken in 12 villages of Bhadravathi taluk, Shimoga district, Karnataka, to educate the farmers in cultivating perennial fodder grasses in their areca and coconut gardens as inter crops.100 farmers were selected ran...
متن کاملStudy 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...
متن کاملEffect of nitrogen supplying sources on nitrogen use efficiency in rice (Oryza sativa L. cv. Shiroudi)
The use of nitrogen fertilizer has a key role in enhancing agricultural productivity worldwide. In order to achieve an effective approach to enhance nitrogen use efficiency in rice, a field experiment was conducted in a randomized complete block design with three replications and 13 treatments on Shiroudi, a high yielding rice cultivar in Rice Research Institute of Iran (Amol) in 2015 and 2016....
