Fertilizer Practices for Bromegrass

Smooth Bromegrass (Bromus inennis Leyss.) is the dominant and mos t dependable perennial forage crop grown in Alaska. Preliminary studies of the influence of fertilizers upon crude protein yields of bromegrass in Alaska were reported in 1953 ( 5) .1 Several additional fertilizer experiments on bromegrass stands established from northern-grown commercial seed have been conduct ed from 1952 to 196 0 and are reported here

Effects of Nitrogen, Lime, and Boron on Candle Rape Grown in the Trapper Creek and Pt. MacKenzie Areas of Southcentral Alaska

When growers in the Susitna Valley and later in the Pt. MacKenzie area of southcentral Alaska inquired as to the feasibility of growing rapeseed, we decided to determine the crops suitability and performance by conducting a field experiment. Bolton (1980) had attempted to predict the feasibility of producing rapeseed in Alaska's interior, but no research had been done in southcentral Alaska. We conducted one study from 1979 through 1981 on Rabideux silt loam (pH 5.1) near Trapper Creek and another from 1982 through 1984 on Kashwitna silt loam (pH 5.4) on the University of Alaska' s research tract in the Pt. MacKenzie area. The first area had been cleared prior to 197 8. This area was rototilled and roots removed in September 1978. The second area was on a tract cleared during the winter of 1981. After clearing, rotary plowing was done twice on the area. During the summer of 1981, roots were removed , and a field cultivator was used twice to loosen and bring roots to the surface

Effects of Potassium, Sulfur, Nitrogen Rate, And Nitrogen Source on Bromegrass Forage Yield and Composition

Production of adequate , high-quality forage is essential for Alaska's livestock industry. Smooth bromegrass (Bromus inermis) is the dominant and most dependable perennial forage crop in the Matanuska Valley and other areas of Alaska. Four areas of Knik silt loam on the University of Alaska's Matanuska Research Farm near Palmer were seeded to bromegrass and were used over a period of 18 years to determine the need of high-yielding bromegrass for applications of potassium (K) and sulfur (S). A bromegrass field on the Woods estate two miles south of Palmer was selected in 1976 for a study comparing three rates of two nitrogen (N) sources with and without S. The soil type was Bodenburg silt loam

Queen mandibular pheromone: questions that remain to be resolved

The discovery of ‘queen substance’, and the subsequent identification and synthesis of keycomponents of queen mandibular pheromone, has been of significant importance to beekeepers and to thebeekeeping industry. Fifty years on, there is greater appreciation of the importance and complexity of queenpheromones, but many mysteries remain about the mechanisms through which pheromones operate. Thediscovery of sex pheromone communication in moths occurred within the same time period, but in this case,intense pressure to find better means of pest management resulted in a remarkable focusing of research activityon understanding pheromone detection mechanisms and the central processing of pheromone signals in themoth. We can benefit from this work and here, studies on moths are used to highlight some of the gaps in ourknowledge of pheromone communication in bees. A better understanding of pheromone communication inhoney bees promises improved strategies for the successful management of these extraordinary animals
