Light Absorption in NO2 Ion in State of Solution (Part III- Effect of Cation)

200mμ band, which is an allowed π-π* transition has been studied in five monovalent nitrates. The blue shift of the band has been found to be proportional to the inverse of the cationic radius

Research Notes : United States : Evaluation of soybean germplasm for stress tolerance and biological efficiency : To evaluate soybean germplasm for biological efficiency in - Nitrogen Fixation

Twenty commercial soybean cultivars from maturity groups IV through VIII were screened for nitrogen-fixation in a growth chamber using Rhizobium strains 3IlB 6,122 and combination of 6 and 122. The data on nodule number, nodule weight, shoot fresh weight, shoot dry weight, and acetylene reduction were recorded. Among twenty cultivars, \u27Lee 74\u27 (MG IV), \u27Bay\u27 (MG V), and \u27Essex\u27 (MG V) were identified as high N-fixers, based on more nodules and high acetylene reduction
