Abstract The experiment was conducted at the Colorado State University Department of Horticulture Field Research Center, Ft. Collins, CO. Plots were established 13 May by use of transplants, with an 18-inch in-row spacing. Individual plots were single row, 20-ft in length, arranged in a RCBD with 4 replications. Insecticides were applied 27 June and 17 July using a CO2 compressed air sprayer delivering 15 gal/A at 45 psi. Food sprays (Good Bug Power Meal) were applied with a hand pump mister on 27 June, 5 July, 13 July and 24 July to cover the plants. Diatomaceous earth (Organic Plus Crawling Insect Killer) was applied 27 June, 4 July, and 17 July. Treatments were hand applied on the first two applications; the use of a Chapin Duster was utilized better to cover foliage on the latter treatment. Evaluations were made by counting all flea beetles on 6 sequential plants in the center of each plot.

Abstract Trials were conducted on spring-transplanted (13 May) broccoli (cv. Green Comet) at the Horticulture Field Research Center in Ft. Collins, CO. Individual plots consisted 20 ft long single rows with 15-in in-row spacing, arranged in a randomized complete block design with four replications. Insecticide applications were made 3 Jun and 21 Jun using a CO2 compressed air sprayer delivering 15 gpa at 30 psi in two passes directed along the sides of the planting. An organosilicant spreader (Kinetic, 6 fl oz/A) was added to all treatments. Evaluations were made by visual observations of flea beetles on six plants/plot.

Field research was conducted in 2002 and 2003 to determine the effect of twin- and single-row spacing and POST glyphosate application timing on light interception, weed control, and grain yield of glyphosate-resistant corn and soybean. Row spacing did not affect light interception measured 10 to 11 wk after planting. Corn grain yield in 2002 was 1.0 Mg/ha higher in single rows compared with twin rows when averaged over glyphosate timing, but was unaffected by row spacing in 2003. Soybean grain yield was similar in 19- and 38-cm single rows, and single-row grain yield was 0.2 to 0.4 Mg/ha higher than the twin-row spacing. Corn grain yields were similar to the weed-free control when glyphosate was applied to weeds 10 to 15 cm tall in 2002 and 10 cm tall in 2003. Soybean yield was maximized by application of glyphosate to weeds 15 to 30 cm tall in 2002 and 60 cm tall in 2003.

Overhead Power Lines

Avian collisions with overhead power lines are a global conservation concern. Collisions are mitigated primarily through marking power lines to increase their visibility. Line marking is typically accomplished via an expensive and potentially dangerous process of hovering a helicopter within 1 m of a wire and installing line markers by hand. Unmanned Aerial Vehicles (UAVs) may offer a less dangerous, less costly alternative that is also less disturbing to wildlife. Herein we describe equipping a commercially available UAV with an installation arm designed in collaboration with the Colorado State University Department of Mechanical Engineering to install line markers on a power line. The UAV installed line markers within a 30 cm target window on a model power line. The proof of concept described here demonstrates the potential utility of UAVs in mitigating avian collision with overhead power lines.

Abstract This trial was conducted at the Horticulture Field Research Farm north of Ft. Collins, CO. Plots were established by transplanting, 4 June, “Green Wave” mustard to single 32-in rows, at 12-inch in-row spacing. Experimental design was a RCB, with 4 replications and individual plots consisted of two 15-ft rows. Treatments were first applied 14 Jun, using a CO2 compressed air sprayer delivering 18 gpa. A reapplication was made 17 Jun. Evaluations were made by counting all flea beetles on the center 4 plants from each row per plot (8 plants/plot total).

Scientific Project

The report shows the results of the Russian-Ethiopian historic and ethnographic expedition – a joint scientific project of two countries, successfully implemented in the early 1990s. Advanced results achieved by this expedition were much owed to participation of several leading Russian and Ethiopian scientific centers and universities – the Institute for African Studies, the Institute of Asian and African Countries at Lomonosov Moscow State University, Addis Ababa University and Institute for Ethiopian Studies, The Primakov Institute of World Economy and International Relations, and others. The participants of the expedition gathered and summarized a large body of data acquired during opinion polls, held in the course of the visits to a number of educational, medical, economic and manufacturing centers and organizations, including workshops, agricultural farms, banks, scientific centers. The collected scientific data has allowed, based on multi-factor analysis, to specify the nature of evolutionary processes in communal relations, efficiency of various aspects of federalism policy in a cosmopolitan country. Its value is reflected by applicability and sharp demand for a scientific view on one of the most troubled sides of social and political life of many African countries, and of the modern world. Based on the field research, a high number of articles and monographs have been prepared and published in the Russian Federation. They include “Report on Field Studies of Ethiopia Carried Out by Russian Historical, Ethnic, Sociological, Expedition, 1990–1992”, “Ethiopia: History, Culture and Ethnicity”, “Ethiopia: the Particular Features of Federalism”, “Drama in Modern Ethiopian Literature and Theatre”, “Mission in Ethiopia. African Policy of the USSR in the eyes of the Soviet Diplomat. 1956–1982”, two volumes of “Africa” encyclopedia and others.
