Using plant extracts and essential oils
€ 28.99 *
ggf. zzgl. Versand

Yield, storability, processing quality and pest management of potatoes, several sets of experiments to investigate the effect of some plant extract and essential oils on the growth, yield attributes, storability, mechanical injures, physiological disorders, processing related characters and insect pest management, and to find out the effect of various application techniques of essential oils at ambient temperature on decay, weight loss and chips and French fries quality are also include in this book. This book also aims to provide a novel anti-sprouting agent for inhibiting growth of potato tubers and processing quality and to identify of terpenoids which may be used to inhibit tuber sprouting as compared to CIPC as a conventional chemical inhibitor. The experimentation and their respective procedures mentioned in this work, are carried out at favorable conditions under very good supervision, and the results are thus obtained, by analyzing the quality parameters on well-equipped laboratories.

Excellent yields, short maturity and other advantages ´´It is claimed for the system described in this book that by its aid no back-yard is too small, no soil too poor, to grow vegetables in such quantity and of such quality as will materially lessen a family´s food bill´´, wrote in 1921 the author in his introduction. Indeed, after nine years´ persistent experiments in the use of electricity and quick-growing methods, A. Carr Bennett developed a method which proved successful ´´in the stimulating of fertile vegetable seed.´´ It also increases the speed of germination and the number of plants that reach maturity, and accelerates maturation too: for example, white turnips reached maturity in just thirty-five days instead of the usual sixty, which allowed for a new crop to be planted. The Bennett method is one of a number of ´´electroculture´´ techniques which almost disappeared after WW2, when agrochemicals started to replace everything and brought with them all the dramatic side effects we know today. It works on all different sorts of plant: ´´In 1918, electrified seed of this description gave on an average over 30 per cent increased yield in bushels per acre; the grain produced was of a better quality, and the straw longer and stouter. This is the ´´larger sphere´´ which the writer is now contemplating. Imagine how much such an increase in wheat-yield would mean to New South Wales!´´ If we replace ´´New South Wales´´ with ´´Mankind´´ then everybody will understand how important this book is. Almost a century later, we are pleased to once again be able present this information to everybody, including farmers, gardeners, agronomists and anyone concerned about food, health and environment.

Precision in Crop Farming
€ 133.99 *
ggf. zzgl. Versand

High yields and environmental control in crop farming call for precise adaptations to local growing conditions. Treating large fields in a uniform way by high capacity machinery cannot be regarded as a sustainable method for many situations. Because differences existing within single fields must be considered. The transition from former field work carried out manually or by small implements to present-day high-capacity machinery caused that the farmers lost the immediate and close contact with soils and crops. However, modern sensing and controlling technology can make up for this deficit. High tech methods that include proximal sensing and signals from satellites can provide for controls that allow adjusting farming operations to small fractions of one ha and sometimes even down to some m2, hence in a site-specific mode. This applies to operations for soil cultivation, sowing, fertilizing and plant protection. This book deals with site-specific concepts, applications and results.

Dynamics, Silviculture and Management of Mixed ...
€ 133.99 *
ggf. zzgl. Versand

The capacity of mixed forests to mitigate climate change effects by increasing resilience and lowering risks is pinpointed as an opportunity to highlight the role of tree species rich forests as part of complex socio-ecological systems. This book updates and presents the state-of-the-art of mixed forest performance in terms of regeneration, growth, yield and delivery of ecosystem services. Examples from more than 20 countries in Europe, North Africa and South America provide insights on the interplay between structure and functionining, stability, silviculture and optimization of management of this type of forests. The book also analyses the role of natural mixed forests and mixed plantations in the delivery of ecosystem services and the best modelling strategy to study mixed forest dynamics. The book is intended to serve as a reference tool for students, researchers and professionals concerned about the management of mixed forests in a context of social and environmental change.

Microwave Based Weed Control and Soil Treatment
€ 86.99 *
ggf. zzgl. Versand

Herbicide resistance has become an important constraint on modern agricultural practices. An alarming increase in weed biotypes that are resistant to herbicides has also been reported. Opportunity exists for a novel weed management technology, which is also compatible with no-till agricultural practices. Microwave heating can kill both emerged weed plants and weed seeds in the soil. When the intensity of the microwave fields is moderate, plants, which have already emerged, are susceptible to microwave treatment. If the microwave field is intense enough, very rapid volumetric heating and some thermal runaway in the plant structures cause micro-steam explosions in the plant cells, which rupture the plant structures, leading to death. Soil treatment requires significantly more energy; however, there are secondary benefits for crops growing in microwave treated soil. These include: significant reduction of the dormant weed seed bank; significant reduction of nematode populations; significant reduction of fungal populations; better availability of indigenous nitrogen for the plants; more rapid humification; and significant increases in crop growth and yield. Microwave weed management and soil treatment is not restricted by weather conditions; therefore, the technology may offer some timeliness and environmental benefits, which are yet to be quantified in a cropping system.

€ 125.99 *
ggf. zzgl. Versand

This book focuses on the existing knowledge regarding the effect of global climate change on tea plant physiology, biochemistry, and metabolism as well as economic and societal aspects of the tea industry. Specifically, this book synthesizes recent advances in the physiological and molecular mechanisms of the responses of tea plants to various abiotic and biotic stressors including high temperature, low temperature or freezing, drought, low light, UV radiation, elevated CO 2 , ozone, nutrient deficiency, insect herbivory, and pathogenic agents. This book also discusses challenges and potential management strategies for sustaining tea yield and quality in the face of climate change. Dr. Wen-Yan Han is a Professor and Dr. Xin Li is an Associate Professor at the Tea Research Institute of the Chinese Academy of Agricultural Sciences (TRI, CAAS), Hangzhou, PR China.

Plant Parasitic Nematodes in Sustainable Agricu...
€ 125.99 *
ggf. zzgl. Versand

Plant-parasitic nematodes are recognized as one of the greatest threats to crop production throughout the world. Estimated annual crop losses of $8 billion in the United States and $78 billion worldwide are attributed to plant parasitic nematodes. Plant parasitic nematodes not only cause damage individually but form disease-complexes with other microorganisms thereby increasing crop loss. Nematode diseases of crops are difficult to control because of their insidious nature and lack of specific diagnostic symptoms which closely resemble those caused by other plant pathogens and abiotic diseases. Future developments of sustainable management systems for preventing major economical agricultural losses due to nematodes is focused on strategies that limit production costs, enhance crop yields, and protect the environment. This book presents a first compendium and overview for nematode problems and their management across North America. Each chapter provides essential information on the occurrence and distribution of plant parasitic nematodes, their major crop hosts, impact on crop production and sustainable management strategies for each region of the continent including, Canada, Mexico and all states of the USA. For each region, a thematic overview of changes in crop production affected by plant parasitic nematodes and their management strategies over time will provide invaluable information on the important role of plant parasitic nematodes in sustainable agriculture.
