Nitrogen Fixation with Non-Legumes
Diazotrophic bacteria convert atmospheric nitrogen to plant-useable form and this input of nitrogen through biological fixation is of great agronomic importance. The contributions presented in this volume relate to free-living nitrogen fixers and the diazotrophs associated with plants. Symbiotic association of Frankia with non-legumes and cyanobacterial associations are also discussed. Research topics covered in this volume include the biochemistry and genetics of diazotrophs, recent developments in improvement of plant-microbe interactions and their molecular basis, the use of molecular probes in taxonomy and ecology of diazotrophs and reports on field applications, agronomic importance and improvement in methodologies for assessing their contribution to plants. This book provides valuable information not only for researchers working in the field of biological nitrogen fixation but also for biochemistry, molecular biologists, microbiologists and agronomists.
The Quest for Nitrogen Fixation in Rice
This book features the latest research advances made in developing nitrogen-fixing rice.
Frankia Symbioses
Five years have now passed since the first symposium on frankiae was held at Harvard Forest, Petersham, Massachusetts, USA and the inauguration of the term actinorhiza. Many advances have been made during these five years in our understanding of the actinorhizal symbioses. Evidence for this was provided by the papers presented at the Wageningen Workshop on Frankia symbioses, held in Wageningen at the Department of Microbiology of the Agricultural University. Most of these papers are now published in this volume of PLANT AND SOIL. We kindly acknowledge the assistance of Anton Houwers, editor of the journal, in planning, reviewing and publishing these studies. Although the papers presented at ...

Urdu Letters of Mirza Asadu'llah Khan Ghalib
Mirza Asadu'llah Khan Ghalib was the brightest luminary of his time in the South Asian, Muslim literary community. A poet in Urdu and Persian, he was endowed with exquisite imagination, sparkling wit, and a charming presence. Ghalib was a brilliant conversationalist, skilled in the art of human relations. In the last twenty years of his life, the political conditions of northern India caused the death or dispersion of many of his best friends. He satisfied his gregarious urges by writing exquisite letters in Urdu, in a delightfully conversational style. By these means Ghalib kept in touch with his scattered friends. These letters were so novel in style that the first collection was published only a month after the poet's death. In this book, Daud Rahbar provides thoroughly annotated English versions of 170 Urdu letters. These letters exemplify the possibility of elevating human relations to an art form, and Rahbar's translation reproduces the delicate flavor of the original Urdu prose.
Biopesticides in Environment and Food Security: Issues and Strategies
Drivers behind food security and crop protection issues vis-à-vis the food losses caused by pests include rapid human population increase, climate change, loss of beneficial on-farm biodiversity, reduction in per capita cropped land, water shortages, and pesticide withdrawals. Integrated pest management, therefore, becomes a compulsory strategy in agriculture, which offers a 'toolbox' of complementary crop- and region-specific crop protection solutions to address these rising pressures. IPM aims at more sustainable solutions by using complementary technologies and one of them is the use of biopesticides including genetically modified cropping systems. The aim is to reduce pests below econom...
Advances in Microbiology
Microbiologist have made significant contributions to basic biological sciences as well as in the applied areas of public health and medical sciences, agriculture, industry and environmental sciences. The most dramatic current development in applied microbiology is due to development of genetic engineering and recombinant DNA technology. The book "Advances in Microbiology" provides a comprehensive and critical review of the work done on different areas of microbiology including agriculture, industry, medical science, bioremediation etc. The book contains 24 chapters. Chapters cover information on the status of microbial diversity, application of biosensors, Azolla as biofertilizer, Frank/a -...
