The Effect Of Photoperiod On Reproduction Of Targhee Ewes, Richard D. Rogen Feb 1982

The Effect Of Photoperiod On Reproduction Of Targhee Ewes, Richard D. Rogen

Electronic Theses and Dissertations

Seasonality of reproduction in sheep has created an oscillating supply of lambs. A more constant supply of lambs would allow more efficient use of facilities and labor by producers, feedlots and packing plants. Seasonal reproduction also limits the lifetime production of the ewe. Extension of the breeding season would provide a more consistent supply of lambs. In addition, more than one lamb crop per ewe could be produced annually. Not only the yearly lamb production but also the lifetime production of the ewe would then be increased. Also, the generation interval would be shortened allowing faster herd improvement. It is …

Relationship Between Soil Moisture And Soil Surface Temperature, Steven Darwin Ness Feb 1982

Relationship Between Soil Moisture And Soil Surface Temperature, Steven Darwin Ness

Electronic Theses and Dissertations

Thermal-infrared imagery (thermography) obtained from satellite altitudes has been shown to be a promising new tool for resource management and development. Satellite-borne thermal-infrared sensors allow the collection of time-sequential thermal-infrared radiation (thermal emittance) data over large land surface areas of the earth at relatively low cost. Thus, any resource which can be related to thermal emittance can be readily monitored. Thermal emittance from a surface is proportional to the fourth power of the surface temperature. Thus any factor which affects the surface temperature greatly affects the surface thermal emittance. · Moisture is such a factor when the land surface is …

Nitrogen Fertility Requirements, Dry Matter Production And Nutrient Uptake Of The Sunflower, Robert Andrew Narem

Electronic Theses and Dissertations

Sunflower (Helianthus annuus L.) has recently become a major crop in the north-central United States. This is the result of the development of high yielding oilseed hybrids, a steadily expanding export market and the plant's inherent adaptability to severe weather conditions. During the early part of this century research was conducted throughout the nation investigating sunflower's potential for silage. As farmer interest declined, the crop was almost forgotten until the introduction of high oil cultivars from the Soviet Union where sunflower had been grown for oil since the mid-1700's. The discovery of cytoplasmic male sterility and fertility restoration then made …

The Effect Of Nitrogen Fertilization On Grain Protein Content And Yield Of Spring Wheat In South Dakota, Syed Dara Tazul Islam Feb 1982

The Effect Of Nitrogen Fertilization On Grain Protein Content And Yield Of Spring Wheat In South Dakota, Syed Dara Tazul Islam

Electronic Theses and Dissertations

It has been predicted that the cost of nitrogen fertilizer will soon triple. Consequently, N management by wheat growers in South Dakota will be even more critical than it has been in the past. Nitrogen is one of the most limiting nutrients for wheat production in South Dakota. Many of the spring wheat producers fail to take advantage of nitrogen fertilizer recommendations based on soil testing. Therefore, it is likely that a simple post-harvest method of determining if adequate N was present for wheat crop would be very beneficial to spring wheat producers. One such method is using grain protein …

Adjusting Potential To Actual Evapotranspiration Rates Applicable Over Large Spatial Regions, Leah Jane Horton Feb 1982

Adjusting Potential To Actual Evapotranspiration Rates Applicable Over Large Spatial Regions, Leah Jane Horton

Electronic Theses and Dissertations

Because of their repetitive flight patterns and broad spatial coverage, satellites hold great promise for supplying the data necessary to predict soil moisture conditions. Already satellite data have been used to predict such input parameters to soil moisture models as solar radiation values and leaf area indices. In addition, surface soil moisture or rainfall events could be detected remotely and used as model inputs. Conceivably, satellite imagery could be used to. predict most, if not all, of the inputs into a soil moisture model. Although the use of satellite data sounds like a timely panacea, there are some inherent questions …

Effect Of Ammonia On Post-Diapause Western Corn Rootworm Eggs And Larvae, Karen Cameron

Electronic Theses and Dissertations

Corn rootworms are the major economic insect pests of corn produced in the Midwest. Economic loss to the grower is through yield reduction caused by larval and adult damage and the cost of insecticidal control measures. Larval damage to corn roots is by tunneling in the roots and damage to the cortical parenchyma. Most of this damage occurs in late June and in early July. Brace root feeding by the larvae can cause the plant to lodge. Adults also damage corn by feeding-on all above ground portions with primary damage to silks and tassels. This feeding disrupts pollination resulting in …
