This paper examined the effect of variety attributes on adoption of improved sorghum varieties in Kenya. Using data from a random sample of farmers, a multivariate probit was used to identify variety-specific drivers of adoption.

The results on the perception of farmers variety attributes showed that improved varieties had desirable production and marketing attributes while the local Download crop improvement adoption and impact of improved varieties in food crops in sub saharan africa or read online books in PDF, EPUB, Tuebl, and Mobi Format.

The book reports on the results of the DIIVA Project that focussed on the varietal generation, adoption and impact for 20 Book. PDF Available The bulletin in the form of “Improved Forage Crop Varieties of IGFRI” is the output of efforts.

11 Quality attributes Crude Protein = Approx. IVDMD = %. Technological change has been the major driving force for increasing agricultural productivity and promoting agriculture development in developing countries. To improve the agricultural productivity and farmers’ livelihoods, several agricultural technologies (improved crop varieties and related agricultural practices) were introduced by various agencies to the farmers in the Rift Valley of   Chapter 4 Crops and varieties.

Farmers will need a genetically diverse portfolio of improved crop varieties, suited to a range of agro-ecosystems and farming practices, and resilient to climate change. Sustainable crop production intensification will use crops and varieties that are better adapted to ecologically based production practices than those currently available, which were bred for   How do scientists create new varieties of maize.

Plant breeding. Plant breeding is the purposeful selection, growth, and cross-pollination of particular plants. This differs from natural selection in that, in nature, plants that do better in a particular environment will set seed and pass on the genes that made them successful in that   The development of improved, fertilizer-responsive high-yielding vari- improving crop germplasm and the development of new varieties through well focused crop breeding programmes have been extended to not benefited from the application of scientific crop breeding.

Each crop has its own story to tell, as evident in this book. There are Conventional plant breeding methods aiming at the improvement of a self-pollinating crop, such as wheat, usually take years to develop and release of the new variety.

During the past 10 years, significant advances have been made and accelerated methods have been developed for precision breeding and early release of crop ://   Varieties in Developing Countries by Dana G. Dalrymple, Dr.

N.C. Brady, former director general of the International Rice Research Institute (IRRI), wrote, “The most significant technological accomplishment of this century in international agriculture is the development of high-yielding cereal crop Improved varieties.

Improvement of a crop lies in its genetic make up and the environment in which it grows and interacts. An improved variety is one that is superior to other existing varieties in one or few characters. It may show high yield than other varieties, early maturity, disease and pest :// About this book.

Two major challenges to continued global food security are the ever increasing demand for food products, and the unprecedented abiotic stresses that crops face due to climate relatives of domesticated crops serve as a reservoir of genetic material, with the potential to be used to develop new, improved varieties of This paper examines the effect of variety attributes on adoption of improved sorghum varieties in Kenya.

Using data from farmers, the paper uses a multivariate probit to identify variety   genetic uniformity in improved varieties, invasive alien species, drought, and environmental degradation. Un‐wise market‐oriented and cash crop production systems have resulted in the loss of farmers' varieties.

Ethiopia is the sole gene pool for globally important crops such Developing Crop Varieties with Improved Nutrient-Use Efficiency. In book: Engineering Nitrogen Utilization in Crop Plants, pp crop varieties that are better at exploiting supplies of With the introduction of improved crop rotations at the end of the sixteenth century, grasses and legumes began to be also grown to an important extent as forage crops on arable land.

In the last decades the importance of amenity grasses increased markedly, due to the demand of the society for new usages like landscape :// Plant breeding is a method for the creation, selection, and fixation of superior plant phenotypes in the development of improved crop varieties which fulfills the need of farmers and consumers.

Primary goals of plant breeding with agricultural crops have aim to improve yields, nutritional qualities, and other traits of Genetic and Genomic Resources of Grain Legume Improvement is the first book to bring together the latest resources in plant genetics and genomics to facilitate the identification of specific germplasm, trait mapping and allele mining to more effectively develop biotic and abiotic-stress-resistant grains.

This book will be an invaluable resource This paper evaluates the ex post impact of adopting improved groundnut varieties on crop income and poverty in rural Uganda.

The study utilizes cross-sectional data of households, collected in   improved varieties of common beans which in most cases are disease resistant, high yielding, drought resistant, and fast cooking.
