Cereal and legume intercropping could improve cereal yield, but the role of in grain quality still lacks a full understanding. A two-year bi-factorial trial was conducted to investigate two planting patterns (mono-cropped wheat (MW) intercropped wheat+faba bean (IW)) four nitrogen (N) fertilization levels (N0, no N fertilizer applied both faba bean; N1, 90 45 kg ha–1 N2, 180 N3, 270 135 bean), ...

Abstract Negative pressure irrigation (NPI), which is a new subsurface technique, promotes vegetable yield, water productivity (WP), and nitrogen use efficiency (NUE). However, it not clear how NPI improves growth, especially in terms of supply characteristics uniformities soil nitrogen. In this study, cucumber pot experiment that had 0 kPa (PW1), –5 (PW2), –10 (PW3), –15kPa (PW4), traditional ...

k field, algebraically closed G finite group Definitions (1) A representation of G over k of degree n is a homomorphism of groups ρ : G→GLn(k), or equivalently, a kG-module structure for an n-dimensional k vector space M , where kG is the group algebra. (2) A representation M is irreducible if it is a simple kG-module, and indecomposable if M 6= N1 ⊕ N2 for any non-trivial submodules N1, N2. No...

introduction: gastroesophageal reflux (ger) is the most common of esophageal disorder in all ages.  ger defined as passage of gastric contents into the esophagus, and ger disease (gerd), (symptoms or complications of ger), are common pediatric problems. clinical manifestations of gerd in infants include regurgitation, irritability, choking, gagging vomiting, poor weight gain and respiratory dis...

Fertilizer management is one of the easiest and most practical ways combating salt stress. This study was done to evaluate alleviative effects nitrogen phosphorus on growth tolerance salt-affected sorghum. A controlled organized in a randomized block design with three replications conducted, testing rates (N0: 0 kg ha−1, N1: 180 N2: 360 N ha−1) (P0: P2O5 P1: 60 P2: 120 ha−1). Nitrogen applicati...

It has been established that maize/soybean intercropping can improve nitrogen use efficiency. However, few studies have addressed how affects nitrogen-fixing bacterial diversity and N fixation efficiency of intercropped soybean. In this study, communities, efficiency, their relationships with soil properties under three fertilization application rates (N0 0 kg/ha, N1 40 N2 80 kg/ha) were explor...

Tillage practices and nitrogen (N) sources are important factors affecting rice production. Few studies, however, have examined the interactions between tillage practices and N fertilizer sources on NH3 volatilization, nitrogen use efficiency (NUE), and rice grain yield. This study aimed to investigate the effects of N fertilizer sources (no N fertilizer, inorganic N fertilizer, organic N ferti...

Abstract Soil microbes perform important functions in nitrogen and carbon cycling the biosphere. Microbial communities rhizosphere enhance plants’ health promote nutrient turnover soil. In this study, we evaluated effects of soil fertilization with organic inorganic fertilizers on abundances distribution genes within maize plants. Our result showed that plants through selected enriched same fun...
