Report 1979

Autor: Graham, Peter H.

A report is presented on N fertilization and fixation in bean crops. The selection of N sources, the time of application and the amount applied guarantees a higher utilization of N by the plant. When the total amount of N required is applied prior to planting, the plant only uses 26 percent of th...

Conference Paper 1982

Autor: Graham, Peter H.

Five of the international agricultural research centers (IARC's) currently have research programs in the area of biological nitrogen (N2) fixation. This paper reviews the activities of the centers in this area and highlights common and distinctive features of the programs, as well as their links ...

Host-determined traits influence nodule initiation, development, and function. and can be of major importance to the proper functioning of the legume Rhizobium symbiosis under field conditions. Thls paper reviews such traits and considers their implications for practically oriented breeding progr...

Autor: Graham, Peter H. Temple, Steven R.

While symbiotic nitrogen (N2) fixation by G. max and P. vulgaris reduces their need for combined N, N2 fixation under field conditions is rarely maximized. This paper reviews constraints to N2 fixation in these species, then examines the genetic variability recorded for traits affecting N2 fixati...

Journal Article 1977

Autor: Munévar Martínez, Fernando Graham, Peter H.

The survival of Rhizobium trifolii (strain CIAT 61) in three carriers was studied. The rhizobial cells did not survive in "cachaza" (a froth obtained when sugar cane juice is boiled in refineries). The survival in peat and coal was good, at least until 120 days after the inoculation. Coal seems t...
