Se implementó un sistema silvopastoril de cerca viva en la finca Santa Maria en el Municipio de Sopo; para el cual se utilizaron 3 especies, Aliso, Acacia decurrens y Acacia melanoxylon distribuidos en 1536 metros lineales, se utilizo un diseño de bloques al azar y 4 replicas con 7 arreglos, T1 (testigo), T2 (aliso), T3 (Acacia decurrens), T4 (Acacia melanoxylon), T5 (Aliso + Acacia decurrens), T6 (Aliso + Acacia melanoxylon) y T7 (Acacia decurrens + Acacia melanoxylon), se evaluaron el crecimiento y desarrollo de los árboles, medidas dasométricas; presencia e incidencia de plagas y enfermedades; Cambios físico-químicos en el suelo, …


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

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 30.4 kg/ha.


Apparent Digestibility In Lamas (Lama Glama), Fed With Brazilian Grass And Wheat In The C.E.A.C., William Edson Velez Contacayo Jan 2006

Apparent Digestibility In Lamas (Lama Glama), Fed With Brazilian Grass And Wheat In The C.E.A.C., William Edson Velez Contacayo

Theses and Dissertations

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 …


Assessment Of Interactions Amoung Viruses Infecting Sweetpotato, Charalambos D. Kokkinos Jan 2006

Assessment Of Interactions Amoung Viruses Infecting Sweetpotato, Charalambos D. Kokkinos

LSU Doctoral Dissertations

Viral diseases, especially those caused by mixed infections, are among the economically most important diseases of sweetpotato. Real-time PCR assays were developed for the detection and quantification of the potyviruses Sweet potato feathery mottle virus (SPFMV), Sweet potato virus G (SPVG), Ipomoea vein mosaic virus (IVMV); the crinivirus Sweet potato chlorotic stunt virus (SPCSV), and the begomovirus Sweet potato leaf curl virus (SPLCV) directly from infected sweetpotato plants. Titers of SPFMV, IVMV, and SPVG were lower in singly-infected sweetpotato plants compared to singly-infected plants of the standard indicator host Brazilian morning-glory (Ipomoea setosa) and the standard propagation host I. nil …
