Nitrogen Content Of Panicum Maximum When Grown With Stylo And Siratro Under Two Moisture Regimes, U R. Sangakkara, K B. Attanayake
Nitrogen Content Of Panicum Maximum When Grown With Stylo And Siratro Under Two Moisture Regimes, U R. Sangakkara, K B. Attanayake
IGC Proceedings (1993-2023)
The impact of 2 popular tropical legumes on the nitrogen (N) content of the rhizosphere and an associated grass (Panicum maximum) in a soil with low N status was evaluated. The effect of 2 soil moisture contents on this process, (a) field capacity - 25% depletion and (b) 50% depletion or below, was also studied. At the high soil moisture level, both legumes increased the N content of soil and Panlcum over the control. The N content of the soil and grass treatments containing stylo was marginally higher than in soils containing siratro. This phenomenon was less marked …

Impact Of Dry Matter At Ensiling On Final Ph And Nutritive Value Of Mixed Cool-Season Haylage, Christopher D. Teutsch, A. E. Teutsch
IGC Proceedings (1993-2023)
Harvesting hay as baleage can allow for more timely harvest, especially in spring months when curing conditions are not ideal. Forage conserved as baleage undergoes anaerobic fermentation in which the sugars are converted to lactic acid, lowering final pH. To successfully conserve forage as dry hay, moisture concentrations must be less than 18%. In contrast, the ideal moisture concentration for baleage is between 55 and 65%. There are a number of producers harvesting and wrapping hay that is not quite “dry enough” to bale but is too dry to ensile. This produces a product commonly referred to by producers as …
Moisture Control, Inoculant And Particle Size In Tropical Grass Silages, S. F. Paziani, L. G. Nussio, D. R. S. Loures, L. J. Mari, José Leonardo Ribeiro, P. Schmidt, M. Zopollatto, M. C. Junqueira, A. F. Pedroso
Moisture Control, Inoculant And Particle Size In Tropical Grass Silages, S. F. Paziani, L. G. Nussio, D. R. S. Loures, L. J. Mari, José Leonardo Ribeiro, P. Schmidt, M. Zopollatto, M. C. Junqueira, A. F. Pedroso
IGC Proceedings (1993-2023)
Decreased fermentation and spoilage losses with improved aerobic stability during feed out can be accomplished by several strategies, such as wilting, addition of microbial additives and moisture absorbents. Particle size reduction may increase bulk density and improve the fermentation. The objective of this trial was to evaluate the effects of particle size, moisture content and a microbial additive on chemical-physical parameters and losses in silages made from Tanzania grass.

Bulk grain angle of repose (AoR) is a key parameter for inventorying grain, predicting flow characteristics, and designing bins and grain handling systems. The AoR is defined for two cases, piling (dynamic) or emptying (static), and usually varies with grain type. The objective of this study was to measure piling angles of repose for corn, sorghum, barley, soybeans, oats, and hard red winter (HRW) wheat in steel and concrete bins in the United States. Angles were measured in 182 bins and 7 outdoor piles. The piling AoR for corn ranged from 15.7° to 30.2° (median of 20.4° and standard deviation …
Effects Of Wheat Grain Moisture: Quality, Germination, And Relationship To Accumulated Growing Degree Days, Kirsten Thomas
Effects Of Wheat Grain Moisture: Quality, Germination, And Relationship To Accumulated Growing Degree Days, Kirsten Thomas
Open Access Theses
Bread wheat (Triticum aestivum L.) is a cereal crop of global importance. As global demand increases, it is essential to increase the quality and efficiency of crop production. Harvesting wheat early provides an opportunity for increased grain quality, and it may also allow the grower to double-crop soybean ( Glycine max L.) after wheat more effectively. Our objectives were to determine if harvesting grain early, at high moisture would, 1) increase milling and baking quality and 2) improve germination potential. As a result of these objectives, we will develop a model to predict dry-down of wheat. Five soft red …

Moisture Potential Affects Rate Of Leaf Appearance In Cool Season Grasses, Nina Cherone Terrell
Moisture Potential Affects Rate Of Leaf Appearance In Cool Season Grasses, Nina Cherone Terrell
McCabe Thesis Collection
The rate of leaf appearance and onset of growth in cool season grasses may be influenced by soil moisture potential and exposure to below freezing temperatures. Levels of moisture potential and days exposed to freezing temperatures, which will restrict leaf appearance, are not well defined. The first part of this study was to determine the effects of different moisture potentials on the leaf appearance rates in two cool season grasses. Italian ryegrass (IRG) and tall wheat grass (TWG) were grown hydroponically at 4 moisture potentials in seed pouches in an incubator under a photoperiod of 13 hours light and 11 …

In Aroostook County, Maine, where the annual average rainfall is 35-40 inches, it is generalized by many that moisture is not a limiting factor in potato production. Weather data for Aroostook do, however, show frequent periods of low rainfall during the growing season, and these periods do cause temporary moisture deficiencies in the crop. Struchtemeyer, based on irrigation research in Maine, showed that the potato plant needs approximately 1 inch of water per week during the growing season. From the 1936 to 1955 Maine Weather Records, Pullen and Schrumpf (23) found that about 70 percent of the time, less than …

Influence Of Moisture And Nitrogen Levels And Harvest Interval On Water Requirement Of Two Genotypes Of Orchardgrass, William W. Wagner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In the semi-arid west, moisture is often the limiting factor in plant growth. High crop production is dependent upon rainfall and supplemental moisture supplied through irrigation. Plants for these areas, which are most efficient in use of water, other things being equal, would be more desirable.

The United States produces about 1.8 million tons of sugar annually. Approximately 75 per cent of this production is derived from sugar beets. The importance of the sugar beet crop in national and world economy is justification for research effort as a means to more economical production.
It is desirable that sugar beet processing be carried out in the most efficient manner. More effective utilization of the sugar beet and its by-products will add stability to the sugar beet industry.
For the past 170 years, since Achard found that sugar could be used for human consumption and that pulp might …

The Effect Of Limited Moisture Supply At Various Stages Of Growth On The Development And Production Of Hybrid Corn, Ralph E. Campbell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Corn occupies from 25 to 30 percent of the crop land harvested in the United States. In recent years the acreage devoted to corn in this country has been decidedly greater than that devoted to any other cultivated crop. In 1944 its dollar value exceeded the combined values of wheat, barley, rye, grain sorghums, and cotton.
Although South Dakota lies on the northwestern fringe of the corn belt, the corn crop is one of the most important in that state. Corn production in that area is somewhat unstable because of drought. Corn often fails to reach full maturity before the …
Leoti For Starch, R. L. Cushing
Leoti For Starch, R. L. Cushing
Nebraska Agricultural Experiment Station: Historical Circulars
The popular forage crop, Leoti sorghum, has possibilities of becoming an important special purpose grain crop for industrial utilization. Investigations of the Department of Agricultural Chemistry have shown that starch manufactured from the waxy grain of this variety has properties similar to those of tapioca starch. Tapioca starch, made from the roots of the cassava plant, has been imported by the United States to the extent of 175,000 tons annually. The chief source of supply, the Dutch East Indies, has been eliminated by the war, and domestic substitutes are being urgently sought by the industry. This type of starch is …

The Regional Adaptation Of Corn In Nebraska, T. A. Kiesselbach, F. D. Keim
Nebraska Agricultural Experiment Station: Historical Research Bulletins
The purpose of this investigation was to determine some of the factors involved in the regional adaptation of corn. The procedure has been to make a comparative study of native corn types, known to be locally adapted to various regional areas in Nebraska through long growth there. The work has been confined to the single species group - Zea mays indentata. No one variety of a common source is grown throughout the state, and therefore it has been impossible to keep within a single variety. It would appear that the data should indicate morphological and histological plant characteristics involved …
