Enhancement of Biological Nitrogen Fixation of Common Bean by Gudni Hardarson (auth.), F. A. Bliss, G. Hardarson (eds.)

By Gudni Hardarson (auth.), F. A. Bliss, G. Hardarson (eds.)

The universal bean (Phaseolus vulgaris L.) is crucial pulse crop in Latin the United States, in addition to in huge elements of Asia and Africa. it really is fairly vital because of its skill, in symbiosis with Rhizobium micro organism, to mend atmospheric nitrogen and because of its excessive nutrient value.
Incorporating contributions from plant breeders, microbiologists, plant physiologists and soil scientists, this quantity reviews the result of an FAO/IAEA Coordinated study Programme (1985--1991), whose major target was once to augment yield and organic nitrogen fixation in universal bean through lowering its reliance on soil and fertilizer nitrogen.
the quantity should be worthy to scientists engaged on organic nitrogen fixation and legume production.

Sample text

This requirement can be expressed mathematically as follows: 15 % Ndff (nfe) % Ndff (fe) -%-N-df-s-'--(n-fc"':"") = % Ndfs (fe) = R (1) Where % Ndff and % Ndfs are the proportions of N derived from the fertilizer and soil, respectively. Accordingly, differences in total N absorbed from the soil by the fixing and reference crop are unimportant, so far as the integrated ratio in which these two N sources is absorbed is similar for both crops. For equation (1) to hold, (i) the reference crop should not fix N 2' (ii) both the fixing and non-fixing crops must absorb N from the same nutrient pool, and (iii) in similar ratios of fertilizer N and soil N during each phase of growth.

Total N, ID, AVand NA methods will be the most suitable for these purposes, when only few and relatively accurate measurements have to be made. Uniform field sites will be important in these studies.
