Evaluation Of The Seed Production Of Tall Grasses Tolerant To Drought And Salinity In The Tamborada Region - Cochabamba, Magali Vallejos Arnez Jan 2006

Evaluation Of The Seed Production Of Tall Grasses Tolerant To Drought And Salinity In The Tamborada Region - Cochabamba, Magali Vallejos Arnez

All Theses and Dissertations

This study was conducted on plots established by the Benson Institute in the Tamborada region of Cochabamba, Bolivia. The objective of the study was to evaluate the seed production of tall grasses that are tolerant to drought and salinity. A design of randomized blocks in divided plots with and without fertilizer was used. The results showed that the species with the greatest number of stems and inflorescence was Bromus inermis with 10.9 and 88.67 respectively. It was determined that fertilization has an effect on plant height. Furthermore, the species with the greatest seed yield was Festuca arundinacea with ...


Agronomic Growth Characteristics Of Two Varieties Of Baby Carrots (Daucus Carota L.) At Three Planting Densities In Walipini (Ingavi Province), María Eugenia Valdez Cuba Jan 2006

Agronomic Growth Characteristics Of Two Varieties Of Baby Carrots (Daucus Carota L.) At Three Planting Densities In Walipini (Ingavi Province), María Eugenia Valdez Cuba

All Theses and Dissertations

Our objective is to study the agronomic growth characteristics of two varieties of baby carrots at three planting densities. The study site is in the area of Walipini, town of Lentanias, province of Ingavi, department of La Paz, Bolivia. In this investigation, the two varieties of baby carrots used were ‘Amsterdam Forcing 3-Minicor’ and ‘Thumbelina’ (Daucus carota var. sativus). Both varieties were planted at densities of 333 plants/m2, 166 plants/m2 and 111 plants/m2 with a planting interval of two days. Statistical differences were observed for the following variables: plant height, root length, root diameter, base diameter, leaf ...

Considering the activity of introducing genetic resources with a high potential for yield, and with a wide adaptation range, it is possible to strengthen the cattle production system, through the production of adequate forage in quality, and quantity. Brazilian grass was introduced to Bolivia in 1974 for demonstrating excellent forage characteristics, and great adaptation qualities to the different ecosystems of the Andes. The material was introduced through the Experimental Station of Patacamaya, with their material supplied through the Experimental Station of Obonuco (Colombia). The following study was conducted at the Agropecuary Experimental Center of Condori, located 49 km. north of ...


Agronomic Evaluation And Comparison Of The Yield Of Six Multiannual Forage Species, Under Dry Land Conditions In The Ingavi Province, Freddy Óscar Paye Paye Jan 2006

Agronomic Evaluation And Comparison Of The Yield Of Six Multiannual Forage Species, Under Dry Land Conditions In The Ingavi Province, Freddy Óscar Paye Paye

All Theses and Dissertations

The agronomical evaluation and the comparative work of six multiannual forage species was conducted in the facilities of the Benson Institute, in the community of Contorno de Letanias, Ingavi province, La Paz. The objectives were to evaluate the agronomic behavior, as well as to evaluate the dry matter (DM) yield of six multiannual forage species (grasses) under local conditions, and to determine the partial cost of production of the studied species. The annual mean temperature was 9.14°C, and 517.6 mm of precipitation. The test was conducted under the random block design test, with six different forage species ...


Energy Value In Llamas (Lama Glama) Fed With Alfalfa Hay (Modicago Sativa) And Barley (Hordeum Vulgare) For Apparent Digestibility In Vivo In The National Camelid Germplasm Bank (Ceac), Edwin Gonzalo Ugarte Huanca Jan 2006

Energy Value In Llamas (Lama Glama) Fed With Alfalfa Hay (Modicago Sativa) And Barley (Hordeum Vulgare) For Apparent Digestibility In Vivo In The National Camelid Germplasm Bank (Ceac), Edwin Gonzalo Ugarte Huanca

In this experiment, we used four male llamas that were three to four years of age from the Khara race. They were divided into two ad libitum feeding groups. The digestible energy (ED) was determined using samples that were sent to the laboratory. These samples were derived from a conventional in vivo assay using the method of total fecal collection in order to determine the difference between energy consumed and energy excreted. Metabolizable energy was calculated by deducting digestible energy, energy loss in the urine and energy loss in the gases (methane). Urinary energy was determined through the measurement of ...
