Book Description
Azolla green manure effect on paddy rice was compared to N fertilization with urea in 4 cultivation systems at two sites in Brazil, during the seasons 1983/84 and 1984/85. Fertilizer nitrogen equivalence was calculated by plotting parameter values obtained in Azolla treatments on the response regressions to N fertilization.

Biological Nitrogen Fixation Associated with Rice Production

Pages : 268

Book Description
Biological nitrogen fixation (BNF) has become important in rice farming systems because this process diminishes the need for expensive chemical fertilizers which have been associated with numerous health and environmental problems. The extensive exploitation of BNF would provide economic benefits to small farmers, avoiding all malign influences of chemical fertilizers. Meanwhile, advances in biotechnology have brought rice genetics to the threshold of new opportunities for increasing rice production. This volume focuses, in six different sessions, on the role of BNF in the improvement of rice production in the light of the current state of the art of BNF technology transfer and diffusion. New ideas on BNF technology in research, extension information and inoculant technology are also included, together with the socio-economic impacts of using BNF in rice farm systems.
