Book excerpt: Dryland agriculture is of more consequence now than ever because the world's dependence on food produced in dryland areas is even greater. In recognition of this, and the fact that global food supply is increasingly interconnected, this volume takes a world view of dryland production continent by continent. The initial chapters of the monograph address the principles that underlie all dryland farming, and are the basis for the following chapters that address dryland farming issues around the world.

Book Synopsis The Biology and Agronomy of Stylosanthes by : Helen Stace
Download or read book The Biology and Agronomy of Stylosanthes written by Helen Stace and published by Elsevier. This book was released on 2012-12-02 with total page 655 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Biology and Agronomy of Stylosanthes covers the proceedings of the 1982 International Symposium on The Biology and Agronomy of Stylosanthes, held in Townsville, Queensland, Australia. The symposium aims to present the developments in the research of the economically important genus, Stylosanthes. Comprised of three parts encompassing 31 chapters, the book discusses Stylosanthes taxonomy, genetic resources, plant-environment interaction, and agronomy. The opening part discusses the taxonomic problems, evolution, and cytogenetic studies of Stylosanthes species. This part also considers the natural variation and distribution, Brazilian species, and existing collection of the genus. The second part of the book presents available data on the occurrence of water shortage in plant tissue and how plants react to it. This part also deals with other environmental constraints to growth and survival, the mineral nutrition, reproductive physiology, and diseases and pest problems of Stylosanthes. A discussion on the influence of mycorrhiza and rhizobium in the genus is also included. The concluding part examines the effect of seed biology on initial pasture establishment and the population dynamics of established pastures. Considerable chapters in this part are devoted to the agronomical aspects of the genus, including nitrogen inputs; chemical composition and nutritive value; and animal and seed production. The book further presents data on global ventures in Stylosanthes, including agricultural projects, research and development, breeding programs, and productivity programs in various regions. This book is an ideal source of information for biologists, agronomists, scientists, and researchers.

Book Synopsis Evaluation of the Nitrogen Supplying Potential of Legumes Placed on the Surface Or Incorporated in a Brazilian Oxisol by : Francisco José Sá Antunes Costa
Download or read book Evaluation of the Nitrogen Supplying Potential of Legumes Placed on the Surface Or Incorporated in a Brazilian Oxisol written by Francisco José Sá Antunes Costa and published by . This book was released on 1988 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based en several experiments, legume green manures are excellent sources of nitrogen for crop production in the cerrado. However, the variability in results among species/varieties and managements illustrate that considerable research must be done before green manuring can be recommended to farmars with a reasonable assurance that the results will be acceptable and consisten. Thus, two experiments, one in the greenhouse and other in the field, were conducted to screen legumes and managements in terms of inorganic nitrogen accumulation in the soil. Both experiments used the same, a typic haplustox of the cerrados region of central Brasil, and the same properties were measured. Ammonium and nitrate levels of the soil samples, and dry matter and nitrogen content of the remaining undcomposed residue on the surface were measured. The fallow soil method was used in both experiments, which were conducted at CPAC/EMBRAPA, Brazil in 1986. Fresh chopped leaves of mucuna aterima (piper and tracy) merr. were surfae placed or incorporrate in pots of 4.5 kg soil in the greenhouse. This experiment was conducted for 178 days. Fresh chopped aboveground parts of canalia ensiformes (L) DC., crotaleria paulina schrank, lablab purpureus (L). sweet, and mucuna aterrima (piper and tracy) merr. were surface placed or incorpoated in a field experiment in the beginning of the season. The experiment was conducted for 168 days with irrigation. In the greenhouse experiment the legume incorporated treatment had an inorganic nitrogen acculation 60 % higher than the surface placed legume treatment. The nitrification was so intense that after 35 days all of the inorganic nitrogen was in the form of nitrate. After 3 and 178 days, 15 and 45 %, respectively of the surface applied nitrogen was not recovered as inorganic in the soil or residue on the soil surface. One can speculate that some of this unaccounted for nitrogen was lost by ammonia volatilization. There was no string evidence that the incorporated legume decomposed faster than suface placed legume. In the field experiment the net nitrogen mineralization of all legumes was so low that there was no significant difference between the acculated inorganic nitrogen of the legume treatments and chek, except for incorpated c.ensiformes. The net nitrogen mineralization of incorporated c.ensiformes, c.paulina, L.purpureus, and m.aterrima were 45, 22, 13, and 15 % of the initial amounts of nitrogen applied as incorporated legume, respectively. There was no signicant difference between the two managements (incorporation or surface placement), except for c.ensiformes. The acculation of mineral nitrogen was very rapid for the firtst 30 days, relatively slow for 30 to 100 days and almost zero between 100 and 168-178 days for both experiments. The controlled irrigation experiment in the dry season was successful in avoiding nitrogen nitrogen leaching to soil below the sampling depth.
