enhancing nitrogen use efficiency is one of the most important strategies for improving productivity in agriculture and reducing risk of environmental pollutions in sustainable agriculture. in order to study the effects of different levels of organic manure and chemical fertilizer on nitrogen uptake efficiency (nupe), nitrogen utilization efficiency (nute) and nitrogen use efficiency (nue) of i...

Identifying Coffea arabica cultivars that are more efficient in the use of nitrogen is an important strategy and a necessity context environmental economic impacts attributed to excessive fertilization. Although breeding data have multi-trait structure, they often analyzed under single trait structure. Thus, objectives this study were Bayesian multitrait model, estimate heritability broad sense...

Regardless of the crop production system, nutrients inputs must be controlled at or below a certain economic threshold to achieve an acceptable level of profitability. The use of management zones and variable-rate fertilizer applications is gaining popularity in precision agriculture. Many researchers have evaluated the application of final yield maps and geo-referenced geophysical measurements...

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...

Nitrogen and rainwater use efficiency in semi-arid smallholder farming systems is low due to soil fertility unreliable rainfall. The objective of this study was evaluate the effect harvesting mineral nitrogen fertilizer on under two sorghum (Sorghum bicolor) varieties. A split-split plot experiment, replicated three times, conducted Mt Zonwe area from 2016/17 2018/19. results showed that water ...

High usage and low efficiency of fertilizers not only restrict sugarcane production but also destroy the soil environment in China. To solve this problem, a network-structured nanocomposite as fertilizer synergist (FS) was prepared based on attapulgite (ATP) polyglutamic acid (PGA). Field demonstrations were conducted from 2020 to 2021. Leaching tests characterization used evaluate ability netw...

Through in vitro tissue culture techniques it is possible to propagate high quality nursery plants faster. Cryotherapy is a promising tool, based on in vitro culture techniques, for achieving in a short time, high frequency of regenerating plants free of viruses. The objective of this review is to present and analyze the results of research conducted in cryotherapy methods based on cryopreserva...

Abstract Seeking food security, contemporary Chinese agriculture has followed a trajectory of overfertilization and associated environmental problems, hence the need for nitrogen-balancing practices that do not compromise yield quality. Here we present national meta-analysis using 224 studies with 1972 comparisons to quantify potential reduce nitrogen (N) fertilization improve outcomes while ma...
