Pasture renovation with herbicide suppression of weeds and no-till seeding of orchardgrassFitzsimmons, James P. 17 June 1993 (has links)
No-till pasture renovation can increase the quality and forage yield of
underproductive pastures. Decreased erosion, lower costs, and less lost
grazing time are advantages of no-till renovation compared to conventional
renovation. Unwanted vegetation is first controlled with herbicides to decrease
competition for introduced orchardgrass. Two field trials were conducted using
a split-plot design to compare three seeding methods and two herbicides. An
Aerway no-till drill, a Tye double disk drill, and broadcast followed by harrowing
were the seeding methods. Paraquat and glyphosate were used to determine
herbicide effect on vegetation control.
Orchardgrass did not adequately survive at either trial site. However,
where some orchardgrass did survive, vegetation control was more important
than seeding method. Competition from annual grasses, many germinating
after herbicides were applied, was the reason for renovation failure. Herbicide
and initial growth for best control.
Yield was doubled in the first harvest by the addition of fertilizer. Early
spring forage production from poor pastures is usually more than adequate, so
the increase from fertilizer is of marginal value unless it is stored for later use.
Yield increase did not carry over to the second harvest when it could be better
utilized. Later application dates would extend yield increases from certain
species if water is available. / Graduation date: 1994

Orchard Floor ManagementRowley, Marc A. 01 December 2011 (has links)
Orchard floor management is vital to tree health, yield, and fruit quality. Current standard management practices include maintaining a vegetation-free tree row and a grass-covered alleyway. This system is effective at limiting competition from undesirable vegetation and creating a favorable environment for the fruit trees. However, limitations to standard orchard floor practices are that the grass alleyway provides no nutrient benefit, and current practices do not readily lend themselves to organic management constraints. Alternative in-row and alleyway systems are requisite to creating improved orchard floor management systems. Three different approaches were used to investigate alternative orchard floor management strategies, including: alternative in-row weed control with combinations of mulch and organic herbicides, alternative alleyway management with legume cover crops, and combinations of in-row and alleyway alternative strategies. Although organic in-row weed control was best accomplished with combinations of straw and acetic acid, this management approach was not economically viable at current costs of labor and supplies, and current fruit prices. Alfalfa and alfalfa clover treatments contributed the most aboveground biomass and nitrogen among alternative alleyway covers, but consumed 45% more water than the conventional grass alleyway. In combinations of in-row and alleyway alternatives, birds-foot trefoil alleyway had a beneficial effect on tree growth compared to grass, while consuming the greatest amount of water. Peach yields were the highest for the integrated compost and NPK fertility treatments that used herbicides to minimize competition. Treatments that experienced the most competition from weeds, no herbicide and reduced herbicide treatments, resulted in lower yields. Weed fabric and tillage in-row weed control methods resulted in the highest tree growth as compared to the straw and alyssum treatments. Finally, results from the combined studies were integrated into a series of recommendations for commercial fruit growers. While alternatives to orchard floor management show a number of potential benefits for growers in the Intermountain West, additional work is needed to determine the long-term viability of these approaches.
