High alfalfa yields have been achieved across most of the US in these small plot trials (Fig. The smallest mean yield of these trials was tons/acre, under rainfed conditions in the semiarid climate near Moccasin, MT.

All of the other 63 nonirrigated sites yielded at least tons/acre. Of those trials in the predominantly. Five Decades of Alfalfa Cultivar Improvement: Impact on Forage Yield, Persistence, and Nutritive Value JoAnn F.

Lamb,* Craig C. Sheaffer, Landon H. Rhodes, R. Mark Sulc, Daniel J. Undersander, and E. Charles Brummer ABSTRACT Previous research has implied that forage yield in released alfalfa.

Private seed companies are paying to have their varieties tested in areas other than at the WSU Prosser Experiment Station. Trials were seeded in, and The WSHGA has arranged for WSU to manage and harvest these trials. Measuring the trade-off between: Alfalfa yield and quality across four harvest periods Our improving knowledge of the relationships among alfalfa yield, quality, and persistence has greatly influenced harvest recommendations made to farmers.

Consider this timeline of how alfalfa harvest management has evolved through the years (Figure 1). The analysis also indicated IAREC alfalfa yield trials the dry matter yield per area of land was much greater for oat grown with alfalfa than oat grown without alfalfa.

In this trial, the leaf to stem ratio of alfalfa and oat plant grown alone was statistically similar (P>) to those grown in a mixture. Effect of autotoxicity on alfalfa stands when alfalfa is seeded (a) immediately following alfalfa plowdown, (b) 4 weeks later, and (c) after 1 year.

The environment, especially weather variables, affects forage growth rate, biomass production, and forage quality.

However, most research has been done at only one point in time, usually at the end of production or harvest. Hay producers need to be able to predict the yield and quality of a forage crop prior to harvesting so they can decide what harvest strategy is required to get a.

As shown in figure 5, on the average over the last 20 years, yields in the UW alfalfa variety trials have been highest in the first and second production years and then began to decline.

This yield decline has averaged 15% in the third production year and almost 30% in the fourth production year. All economic analysis would clearly indicate. Alfalfa (Medicago sativa L.) forage production is seldom limited by one pest, but by a collectinn of pests.

Consequently, alfalfa cultivars need multiple pest resistance (MPR). Crossing alfalfa str. yield data from Uniform Alfalfa Trials established In, and at Lethbridge, Alberta and in at Swift Current, Saskatchewan, denoted by L83, L84, L85, and S85, respectively, were used.

Forage yields were observed for five years on L83 and L84 and six years on L85 and S All trials had varieties, were laid out in randomized. Methods currently available for inoculating alfalfa (Medicago sativa L.) seed with Rizobium meliloti were evaluated to determine their ability to produce effective nodulation and to increase forage yield under moderately acid (pH –) soil inoculation treatments were applied in a field experiment: no inoculant, g inoculant/kg seed applied without inoculant sticker, 5.

4 or 11 lbs/A of alfalfa seed. Forage yield was measured the year of overseeding and the year following overseeding (Year 2). Harvest number was the same for each treatment within a year. Numbers above bars indicate seeds planted Kehr et al., Nebraska 2 29 Michigan 4 16 Tesar, Illinois 1 23 26 Miller, required to maximize alfalfa yields, but the manner and the yield components associated with K-induced variation in agro-nomic performance remains unclear.

Studies have shown that increased forage yields obtained with K fertilization of alfalfa were mainly the result of increased mass per shoot (Berg et. Average yields from performance trials are compared to yields computed by the model in Fig.

Kolmogorov-Smirnov test (Conover, ) was used to assess the validity of the yields generated by the calibrated alfalfa growth simulation economic analysis requires only annual yields, but to ensure accurate results, yields from each cutting and annual yields were tested.

N2 - Previous research has implied that forage yield in released alfalfa (Medicago sativa L.) cultivars declined slightly between and Our objective was to compare alfalfa cultivars released during the past five decades side by side in replicated yield trials to test for any changes in forage yield.

Maximizing Alfalfa Yield and Quality QAlfalfa yield is directly related to profit QManaging yield and quality depends: Selection of fields w/ well-drained soils, no perennial grass, correction of soil pH and other nutrients, planting high-yielding varieties, manage for rapid establishment-Manage production for high yield – annually fertilize.

Alfalfa Variety Trial Data Alfalfa growers need to select alfalfa varieties based on yield and quality performance in their specific region.

The varieties best suited for the high elevation intermountain valleys of northeastern California are different from the varieties adapted to the warmer, longer-season production areas in the remainder of.

and high yields that can be consumed by livestock readily and has high protein content and it is also rich in minerals and vitamins (Soya et al., ; Geren et al., ).

Yield characteristics of alfalfa have been reported as follows; green herbage yield kg ha-1, dry matter yield.

alfalfa, as well as the characteristics of the alfalfa varieties and brands that are offered for sale. Then they can make the appropriate choice that will insure what I believe are the three most important requirements in alfalfa production.

High yields. bers beneath yield columns indicate whether the difference between yields is due to genetics or to other factors, such as variations in the environment.

If the yield difference between two en-tries equals or exceeds the LSD value, the higher-yielding entry probably Alfalfa Field Crop Trials Results. Variety improvement. Over the past 50 years’ variety trials, the average impact of variety on yield has been approximately 30% of the mean value (Putnam et al., ).It is highly doubtful that irrigation practices would be significantly different for higher-yielding varieties compared with lower-yielding varieties—at least they were not in these controlled trials.

Forage Yield Trial Applications and Results from to Under irrigated conditions, which in these trials were designed to minimize yield limitations due to drought, nearly one-half of the trials produced yields exceeding 8 tons per acre.

In every Western state except Montana and Wyoming, at least one location produced alfalfa dry hay yields. A multi-year Purdue study found that the highest alfalfa yields were recorded when fertilizer rates were 50 pounds of P 2 O 5 per acre per year, and pounds or more of K 2 O per acre per year.

There was no significant yield increase when rates of more than 50 pounds of P O 5. Alfalfa Variety Ratings Winter Survival, Fall Dormancy & Pest Resistance Ratings for Alfalfa Varieties This National Alfalfa & Forage Alliance publication is intended for use by Extension and agri-business personnel to satisfy a need for information on characteristics of certified-eligible alfalfa varieties.

2. Alfalfa, the “queen” of forages, is an excellent source of both fi ber and protein for dairy cattle. 3. New cropping systems using low levels of growth inhibitors will allow farmers to establish alfalfa during the last year of corn in a crop rotation.

Th e yield advantage can be seen in the alfalfa .Alfalfa has spread and become popular because of its productivity and high feed value. It has the highest yield potential of any perennial forage legume adapted to the United States.

It is also among the highest in feed value. With its high protein content, it complements corn silage and grains in .The effect of winter crown rot [Coprinus psychromorbidus] on stand density and forage dry-matter yield of alfalfa (Medicago saliva) was examined during in field trials in Saskatchewan.
