Product Description
In today's world, we are witnessing simultaneous breakthroughs in reproductive technologies, genomics, and molecular biology. Advances in molecular genetic technology and understanding of the bovine genome have led to the development of tools that can be used to enhance profitability on cow-calf enterprises. Factors Affecting Calf Crop: Biotechnology of Reproduction provides a detailed compilation of current and forthcoming technology for managing reproduction in cattle. The book discusses topics such as: approved techniques for controlling the estrous cycle in cattle; managing follicular growth with progesterone, estrogens, and prostaglandins; freezing, thawing, and transfer of cattle embryos; application of embryo transfer to the beef cattle industry; embryo transfer in topically adapted cattle; new factors affecting bull fertility; embryo collection and utilization technology, in vitro fertilization, somatic cell cloning, and genetic technologies; uses of real-time ultrasound; and sexed semen. Over 25 leading animal scientists have combined their expertise to produce the first single-source reference that covers successful reproductive techniques that will, most likely, be the wave of the future. Expansive in scope, the book addresses current biotechnologies as they impact the production of beef cattle. Written at a level to appeal to the researcher, commercial producer, or student, Factors Affecting Calf Crop: Biotechnology of Reproduction presents you with a wealth of technologies applicable to animal agriculture. ...

Product Description
With limited water resources to divert for agriculture,innovations aimed at increasing efficient use of irrigation water mustbe developed. Among the means to survive the consequences of waterscarcity and yet to sustain high crop production under irrigatedagriculture with decreasing share of water, deficient irrigationprograms are highly valued and their adoption is widely promoted.However, to ensure that the same level of crop yields as in fullirrigation can still be achieved with deficient irrigation, experienceregarding crop yield response to deficient irrigation programs must begained. This book discusses general concept and management issues ofdeficient irrigation practices, covering a wide range of field cropsincluding cotton, maize, soybean, wheat, sugar cane, and the like,based on five years of field research implemented in fourteendifferent countries, in Latin America, Africa, Europe and Asia.Additionally, guidelines are given for experimental methodology anddata analysis for evaluating crop yield response to deficientirrigation. Experimental data, discussions and cited references willbe an asset not only to field irrigation engineers but also toresearch scientists including soil and irrigation scientists andagronomists, for whom the book would be an invaluable referencesource. ...

Product Description
Lessons learned in Latin America is about the use and dissemination of cover crops in different agroecosystems need to be made more widely available not only to Spanish speaking, but also Anglophone regions. This publication aims to inform a wide range of actors involved in rural development projects, as well as those in applied research, of the potential of cover crops as components of low external input agricultural (LEIA) systems.Cover Crops are, or have the potential to be, an important component in complex, diverse, risk-prone and resource poor farming situations.

The publication includes selected case studies from four different countries within Latin America. These address key issues regarding crop cover integration in LEIA systems. A wide range of agroecosystems are covered by the case studies, so that the information can be adapted for use in other regions. The key issues covered by the case studies are the following:Cover crops in annual cropping systems (Honduras), Cover crops in Perennial crops (Bolivia), Role of cover crops in animal husbandry (Mexico), Cover crop systems - Soil improvement and conservation (Honduras), Alternatives to slash-and-burn (Mexico), Diffusion aspects of cover crop based systems, Applied research activities for agricultural systems improvement (Bolivia), Action research with campesino farmers in South-East Mexico ...
