The Effect Of 2,4-D, Grazing Management And Nitrogen Fertilizer On Pasture Production, M. K. Mccarty, M. L. Cox, D. L. Linscott

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Many pastures in eastern Nebraska and surrounding areas have gradually decreased in productivity. Over a long period of heavy grazing, native warm-season grasses have been largely replaced with Kentucky bluegrass, other less desirable grasses, and broadleaf weeds. A program was started in 1949 to study the effectiveness of protection from grazing in changing the botanical composition and yield of a pasture where the predominant forage was Kentucky bluegrass. Several weed control treatments were included in this experiment to determine if mowing or spraying would hasten the return of more desirable forage. After weed control and differential grazing treatments had been …

A Mode Of Action Of Herbicides: Inhibition Of The Normal Process Of Nitrite Reduction, Lowell Klepper

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Herbicides were shown to interfere in the normal process of enzymatic nitrite reduction by the plant in photosynthetic and nonphotosynthetic plant tissues with little effect on nitrate reduction. This preferential inhibition caused nitrite to accumulate. The occurrence of free nitrite within the plant can help to explain the toxicity symptoms, nastic growth reactions, abnormal metabolism and rapid death due to herbicide action. This blockage of nitrite reduction was shown with all photosynthetic inhibitor herbicides tested and with numerous other herbicides. The effect was demonstrated using an in vivo assay, intact green plants and germinating seedlings. A basic in vivo method …

Skeleton Weed : The 1974 Narembeen Campaign, C R. Chambers

Journal of the Department of Agriculture, Western Australia, Series 4

Skeleton weed took an alarming, historic turn in Western Australia at the 1974 New Year.

After a decade of an almost complacent pattern—control of one or two small outbreaks annually by the Agriculture Protection Board— general alarm erupted with the discovery of big areas at Pithara and mainly Narembeen.

What followed was a massive movement and engagement of not only Department staff but also the farming community in an attempt to beat this outbreak.

The Effect Of Applied Nitrogen And Subterranean Clover On The Growth Of Doublegee, D J. Gilbey

Journal of the Department of Agriculture, Western Australia, Series 4

Until 20 years ago doublegees in Western Australia were mainly confined to the red-brown earth soils of the wheatbelt.

Since then, they have spread to light loamy sand soils in the wheatbelt, many of which have carried subterranean clover from the mid-1940s onwards.

It has been widely presumed that the spread of doublegees on to the lighter sandy soils of W.A. can be associated with the establishment of subterranean clover on these soils.

This report summarises the results of a glasshouse experiment on the effect of clover and nitrogen on the growth of doublegee.

This farm has paddocks ranging from relatively newly sown pastures with a high clover percentage, few weeds and high dry matter production (resown 1973 and 1974), through to extremely poor pastures with as little as 3 % clover and a weed component of over 80% (resown 1970 and 1971)... b.

Weed Trials 1974 Summary - Annual Ryegrass Control - Wild Oats - Cereal Tolerance To 2,4-D - Annual Ryegrass Toxicity, G. A. Pearce

Experimental Summaries - Plant Research

A herbicide trial and demonstration was commenced in 1973 and the treatment repeated in 1974. the objective was to control the annual ryegrass which was the dominant species and allow the scattered plants of sub clover to re-establish a clover dominant pasture. (See table) Despite the high reduction of seed stalks formed on some treatments in 1973 the ryegrass was only reduced by 50 per cent on the best treatment in 1974, The reduction in seed production in 1974 will no doubt further reduce the density of ryegrass in 1975 but eradication is unlikely. The value of burning in destroying …

Pasture Species Investigations - Wheat Belt (May, 1975), N. R. Mckeown

Experimental Summaries - Plant Research

Results from trials comparing the growth and persistence of a number of annual pasture legumes are presented in this report. Rainfall conditions during the year are described briefly and a table of annual and growing season rainfall at relevant centres is appended. The experiments are grouped as follows according to average annual rainfall:- Zone A - Average annual rainfall > 400 mm Zone B - Average annual rainfall 345 - 400 mm Zone C - Average annual rainfall < 345 mm and then, further, on soil type. District Rainfall, 1974. 71LG16,, 72LG3, 74KA3, 70OTS2, 72TS5, 70NA3, 71TS22, 74NO3, 70ME4. The early break, with good rainfall continuing through most of the growing season, provided optimal conditions for most wheat belt trials. These conditions were in direct contrast to the dry years of the late 1960's and early 1970's. In 1974, legume growth on droughty deep sands should have been at its best. Serradella responded at Kukerin in direct relationship with earlier heavy dressings of potash. West of Three Springs, serradella and Tornafield medic stayed a little ahead of Harbinger medic and well ahead of Daliak sub. clover and rose clover. On deep sands at Marchagee and Arrino, subterranean clover was the only species worth considering. The failure of Eragrostis curvula to persist through the dry 1973-74 summer after good germination in late winter, indicates a need for more work on the establishment of this grass on deep sands. The low yields of dry matter at Tincurrin do not offer much incentive for such work, but Eragrostis, lupins and serradella probably give the best chance of pasturing the grossly infertile, erodable sands. Under favourable conditions, Geraldton sub. clover continued to show its versatility and aggressiveness. On an alkaline loamy sand at Lake King, waterlogged for periods during the winter, Dwalganup, Geraldton and Northam A produced more dry matter than a wide range of other pasture legumes. At Walgoolan, Geraldton maintained better than 503 content in mixtures with other sub. clover cultivars sown in 1970, while in a trial at Marchagee there was evidence of gradual, aggressive regeneration of Geraldton from a sparse pasture sown before the trial. Only two new legume species trials were planted in 1974, and these were not successful. Trial 74KA3, east of Katanning, demonstrated the need for timely planting. Had seed been available on time, the trial would have been planted before the onset of heavy rains and would have given better results. The failure of Tornafield and Harbinger on 74N03 should not weight the record unduly against these medics; :they have never excelled on clay loams, and they were sorely harassed by redlegged earthmite. The medics will not be replanted, but Northam A and Geraldton will be observed in 1975. :

Residual Effects Of N-K Fertilization Of Coastal Bermudagrass On Spring Populations Of Weed Species, R. A. Allured, E. C. Gordon, R. E. Frans, Lyell F. Thompson

Journal of the Arkansas Academy of Science

A "Coastal bermudagrass" (Cynodon dactylon L.) sod was treated during a five-year period with rates of N and K fertilizers ranging from none to high levels of both elements. In the spring of the sixth year differences in weed species and population densities among the treated plots were observed. Spring weed counts showed that high rates of N fertilizer reduced the number of weed species and the total broadleaf weed population density by 37 and 81%, respectively. The higher rates of K fertilizer also reduced the population density of common dandelion (Taraxacum officinale Weber) and yellow toadflax (Linaria vulgaris Hill),the …
