für 62.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
En 1987 la Dra. Martínez inició en el CSIC un trabajo de selección de la variedad Albariño (Vitis vinífera L.), fruto del cual se seleccionaron 11 clones, que se conservan en la colección de variedades de vid de la Misión Biológica de Galicia (CSIC). En el año 2000, los coautores de esta obra, emprendieron el estudio de dichos clones desde el punto de vista agronómico y de resistencia a Mildiu. Para evaluar la resistencia a mildiu en campo, pusieron a punto una técnica original de muestreos y análisis de imágenes en hoja. Los resultados obtenidos permitieron demostrar la existencia de una elevada variabilidad entre los clones estudiados, tanto a nivel agronómico, como de sensibilidad a Mildiu, lo que demostró que la preselección clonal había sido exitosa. Los resultados obtenidos abren la posibilidad, en la variedad Albariño, de elegir clones más o menos adaptados a las diferentes condiciones de los viñedos o de reducir el número de tratamientos fitosanitarios. Todo ello implicaría una mayor rentabilidad, menor deterioro del medio ambiente y la elaboración de vinos más saludables. Las conclusiones alcanzadas en este trabajo permitirán abordar nuevas líneas de investigación. ····· 103611290

Gender Disparity in Agricultural Technology Adoption

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Agro-pastoral women make significant contribution to subsistence agriculture and ensuring food security and the mainstay of the farm labour. They work in all aspects of agriculture. In addition to their active engagement in agriculture and livestock production women are responsible for all household chores, mainly as a result of the gender division of Labour. However, agricultural development programs and planning give inadequate attention to women farmers and their needs, and hence their farming activities take place on an ever shrinking resource base with extremely primitive technology and with severely stretched time resources. The model result revealed that adoption of improved sorghum package is biased by gender, where Female Headed Households adopt the package relatively less due to Socio-cultural, Economic, and Institutional factors. Therefore, equal access to resources and extension services, gender sensitive participatory technology development efficient inputs delivery systems, and linkage to market are essential to accelerate agricultural development through technology adoption. ····· 103611237

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Nutritional status of children is greatly depended on nutritional knowledge and feeding practices of the mother which vary substantially between population due to socio-demographic, economic and cultural variations. Childhood malnutrition is a major health problem in Bangladesh, but the relationship between maternal knowledge and practices with the nutritional status of children have not been adequately studied in Bangladeshi population. This relationship along with factors affecting the maternal knowledge and practices, have been addressed in this work including 400 mothers of 2years children. This study has also identified misconception regarding mothers` nutritional knowledge and underlying reasons of improper child feeding practices. The work emphasizes on the importance of providing nutritional knowledge to the mothers (irrespective of educational status) and it also highlights the need for policy and strategy adaptation to provide more effective behavior change education targeted particularly to the people with lower education levels. ····· 103611231

Machinery and Power Selection Models for Paddy Wheat Farms

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
Power and machinery is a single largest cost component, constituting about 60% of the total investment cost on mechanized farm. The profit of a farm depends, to a great extent, on the appropriate mechanization planning of the farm. Selection of proper size of power source(s) and its matching equipment is of paramount importance for an efficient mechanization planning.The bottleneck in the farm mechanization planning has been due to complexity of available machinery systems and their diversity with respect to type, size, number and operational characteristics. The process is further complicated in multiple cropping farms. Several models have been developed for the selection of agricultural machinery system using different techniques, like, linear programming, heuristic models, dynamic programming, and least cost approach. All those models were crop and location specific. This book describes the development of computer based mathematical models using least cost technique and a software for the selection of optimum power and machinery system. The developed models were validated for paddy-wheat crop rotation of Northern India. ····· 103611217

Challenges in science and industry usually arise from over-complex systems analyses. Simple and feasible on-farm approaches of barley use will enable concurrent improvements in rumen microbial efficiency and yield, post-rumen starch and protein assimilation, milk and meat outputs, animal immune function, and adequately persistent economic life. Optimizing barley grain value for ruminants has been a major global and environmental challenge. Mismanagement in feeding and processing barley grain for high-producing dairy and beef cattle can easily make a fiasco from the pearl of cereals. With its nutritional exclusivities underlined, optimum barley grain feeding to postmodern ruminants is a factual art that will either matchlessly profit or harm rumen microbes, cattle production and farm economics. ····· 103611212

The transformation of insoluble organic N via particulate and dissolved organic matter (POM and DOM) into inorganic N may represent the bottle neck mechanism in N mineralization. However, it is unknown how POM fractions are related to DOM pools, and how these particulate and dissolved pools are quantitatively involved in N mineralization. To understand and quantify the fate of these pools in N mineralization, we conducted an incubation experiment with 15N labeled radish residues to trace the flow of 15N through the different N pools. POM was fractionated with density fractionation as light and heavy fraction (LF and HF). Our analysis showed that neither DON nor POM function as a distinct N source fraction in soil. The collected DOM was predominantly recalcitrant (~80%), suggesting that the bioavailable DOM fraction cannot be measured with current sampling techniques. ····· 103611196

The purpose of this study is to determine the factors underlying the adoption of coffee hulling by farmers, and to estimate the price elasticities for hulled and unhulled coffee sold. 300 farmers were randomly selected and interviewed using a structured questionnaire. The censored Tobit model was used to analyse the factors that influence the sale of hulled coffee. Two OLS models for the marketed supply of unhulled and hulled coffee were estimated and their corresponding elasticities determined. The results indicate that higher market prices of hulled coffee positively and significantly (p0.01) enhance the proportion of hulled coffee sold, while distance from the farmer s home to the coffee processing factory and drought conditions during the season significantly (p0.05) reduce the proportion of hulled coffee sold. The sale of hulled coffee was found to be more price responsive than the sale of unhulled coffee both in the short and long run. Based on these findings the study recommends supporting the development of farmer institutions as a way of promoting the uptake of coffee hulling and value addition to improve farmers incomes. ····· 103611156

Indonesian Fisheries Management

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray
The analysis of the Indonesian fisheries assessment and management framework has revealed a picture of management gaps, data inconsistency and inadequacy of regulations to achieve the sustainability of fish resources. The open-access nature of the fisheries and complexity of licensing systems, split between three levels of government, make planning and enforcement difficult. To deal with the increasing exploitation of fisheries resources, the Indonesian Government enacted Fisheries Law No. 9 (1985), later followed by Fisheries Law No. 31 (2004). These laws covered most aspects of fisheries in Indonesia, including jurisdiction, management, exploitation, development, delegation of responsibilities, as well as monitoring, control and surveillance. Despite the good intention of these laws, there remain major problems in implementation, particularly in relation to the lack of agreement concerning the sharing of the marine jurisdiction and fisheries management responsibilities among the national, provincial and district governments within Indonesia. In general, fisheries officers understood the fisheries laws very well, but found it difficult to implement in a practical sense. ····· 103611145

Water and Nutrient Management in Bed Planting Wheat

Efficient input management along with varietal improvement is the two basic aspects that can help us in achieving the target. To fully exploit the potential of wheat yield the development of special management practices like sowing method, management of water, nutrient and weed etc are prime need which ensure for higher yield. The new resource conservation technology FIRBS (furrow irrigated raised bed planting system) can reduce the water usage by 25-40% and saved 25% of seed and nitrogen without any yield reduction compared to conventional tillage. Wheat productivity can be increased by providing copious water at the right time according to availability of irrigation water. Various essential nutrients play pivotal role in maintaining the quality of grains. Nitrogen being the constituent of all amino acids and protein fractions has great influence on growth and yield-attributing characters of wheat in relation to its major uses in bread making. Thus, the judicious use of available irrigation water and application of suitable dose of fertilizer in respect to available soil moisture plays important role in minimizing the present large gap between yield achieved and yield achievable. ····· 103611133
