Elliptical Combing Motion For Harvesting Bell Peppers, J. H. Wilhoit, George A. Duncan, Larry G. Wells

Biosystems and Agricultural Engineering Faculty Publications

A new concept for mechanically harvesting bell peppers, intended specifically for multiple-pass harvesting, utilized spaced horizontal fingers combing vertically upward through plant foliage in an elliptical path alternating from both sides of the row. An apparatus based on this concept was designed and built, and harvest tests were conducted to determine the effect of two main machine operating parameters, vertical picking speed and disk angle. Harvesting performance was evaluated in terms of harvest efficiency, fruit damage, and plant damage as it related to multiple-pass harvesting. Fruit removal, both harvestable size and immature, increased significantly as vertical picking speed increased. Branch …

Soybean Chlorosis Studies On High Ph Bottomland Soils, E. J. Penas, R. A. Wiese, R. W. Elmore, G. W. Hergert, R. S. Moomaw

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

Soybean varieties are different in tolerance to lime-induced chlorosis. Field trials were conducted to evaluate variety performance on soils where chlorosis in soybeans was a known problem. Thirty-six varieties out of 177 were identified as tolerant to soil conditions that cause chlorosis. Eleven varieties of these 36 were found to have the most consistent yield performance on high pH soils. Tolerant varieties must be planted at adequate densities for best performance. A seeding rate of 13.5 seeds per foot of row, the highest seeding rate employed, did not appear to maximize yield on soils where chlorosis was severe. On some …

Pesticide Use On Crops In Nebraska - 1987, Maurice Baker, Nancy Peterson, Shripat T. Kamble

Historical Research Bulletins of the Nebraska Agricultural Experiment Station

This is the third and most comprehensive study of pesticide use on crops in Nebraska. The first was completed in 1978 and the second one in 1982. The first study indicated that approximately 25 million pounds (11.34 million kg) of active ingredients were used on the major crops in Nebraska. This increased to approximately 30.2 million pounds (13.7 million kg) in 1982. The USDA requires accurate information to meet their responsibilities. Thus, this survey was undertaken to determine: 1) the use of pesticides on crops, pasture and rangeland and 2) to identify pest management practices.

Triazine Resistant Pigweeds In Kentucky Corn Fields, Jonathan D. Green, Michael Barett, Mike Radford

Agronomy Notes

Smooth pigweed (Amaranthus hybridus) control from atrazine and/or simazine (Princep) has been unsatisfactory in some Kentucky corn fields. Many of these fields have grown corn where one or both of these herbicides have been used continuously for several years. These two triazine herbicides, particularly atrazine, are used annually on over 90% of the corn grown in Kentucky. Other areas in the U.S. and around the world have reported. unsatisfactory control from atrazine where triazine resistant pigweed has developed.

Toward Better Minimum Tillage For South-Coastal Sandplain Soils, W L. Crabtree

Resource management technical reports

Seventeen farmers compared their conventional cropping practices with some form of minimum tillage cropping. The minimum tilled crops yielded 21 percent less grain than the conventionally sown crops. The reasons for these decreased yields were in most cases related to inexperienced management. The minimum tilled treatments usually had very poor weed kill strategies which often resulted in large weeds at sowing, very cloddy seed-beds, and numerous insects in the young crops.

Automated Harvesting Of Burley Tobacco I. System Development, Larry G. Wells, George B. Day V, Timothy D. Smith

Biosystems and Agricultural Engineering Faculty Publications

A fully automated system for harvesting and handling mature buriey tobacco has been developed. This article identifies the operations essential to this harvesting concept and describes the development of the mechanisms by which they were accomplished. The system detaches, inverts and places mature plants into portable holders for air curing under waterproof covering without requiring any manual handling of the crop. Manual labor currently required to harvest buriey tobacco would be reduced by 80-85% and the system would eliminate the drudgery associated with manual handling. The harvesting system has an approximate capacity of 1.4 to 2.0 ha/day (3.5 to 5.0 …

Automated Harvesting Of Burley Tobacco Ii. Evaluation Of System Performance, Larry G. Wells, George B. Day V, Timothy D. Smith

Biosystems and Agricultural Engineering Faculty Publications

A prototype system for fully automated harvesting of burley tobacco has been developed and tested. Three years of field testing has shown that mechanical losses associated with the system were only slightly higher than via conventional methods. The system performed reliably at a sustained harvesting rate of approximately 1.4 ha/day (3.4 acre/day), while indicating that a rate of 2 ha/day (5 acre/day) should be easily achievable. The system is operated by two workers and reduces conventional labor requirement by approximately 80-85%.

The Effects Of Within-Row Spacings & Cultivars On The Yield Of Bush Snap Beans (Phaseolus Vulgaris L.), Timothy Hafner

Masters Theses & Specialist Projects

The effects of within-row spacings and cultivars on the yield of bush snap beans (Phaseolus vulgaris L.) were studied in two experiments. In each experiment, two cultivars and four within-row spacings (8, 15, 23 and 30 cm) were arranged in a split-plot with four replications. Spacing treatments were the whole plots and cultivars were the split plots. In 1988, the two cultivars were 'Blue Lake 274' and 'White Half Runner'. In 1989, the cultivars were 'Blue Lake 274' and 'Kentucky Wonder 125'. All rows were spaced 91 cm apart. Pods were harvested and oven dried. The data were subjected …

Response Of Soybeans To Available Potassium In Three Kentucky Soils, John H. Grove, William O. Thom, Lloyd W. Murdock, James H. Herbek

Agronomy Notes

Soybeans are produced in nearly all of Kentucky's soil physiographic regions. Soybean response to potassium (K) fertilization and soil test Kvaries with soil type and location. This variation may be associated with the wide range in soil chemical and mineralogical properties among the different regions. Of particular interest are differences in that level of soil test Kat which no further yield response to K fertilizer application would be expected. The main objective of this work was to evaluate the soil K-soybean response relationship on three different field sites where soybean yields were increased by fertilizer K. Several measures of soil …

The Effect Of Phosphorous Placement & Rate On Phosphorus Uptake, & Growth & Yield Of Tomatoes, Christopher Thompson

Masters Theses & Specialist Projects

Research was undertaken in the summer of 1989 to determine the effect of phosphorus placement on the yield and quality of field grown tomatoes Lycopersicon esculentum. A subsequent study was undertaken in the winter of 1989 to determine the effect of phosphorus rate and placement on the early growth and phosphorus uptake of young tomatoes in the greenhouse.

The purpose of this study was to attempt to find the most efficient placement and rate of supplemental phosphorus when growing tomatoes. It has been shown that placing phosphorus in a concentrated zone in contact with plant roots results in more …

Soil Test Potassium As An Indicator Of Tobacco Response To Band Application Of Fertilizer, J. L. Sims, Kenneth L. Wells, E. C. Schwamberger

Agronomy Notes

During the past 10 years, several studies have been conducted at Lexington on the University of Kentucky Experiment Farm to compare the effect of banding fertilizer 10 to 12 inches to each side of the row with preplant broadcast applications on growth and yield of burley tobacco. Generally, banding most of the nitrogen and potassium has led to fewer problems with salt and manganese toxicity and to improved growth during the early season. However, as compared to broadcast application, banding has had varying effects on cured leaf yields. In 'some experiments banding resulted in higher yields, in other experiments in …

Potential Use Of Ethephon To Control Lodging Of Soybeans, Larry J. Grabau, Robert C. Pearce, J. V. Konsler

Agronomy Notes

Lodging is sometimes a serious problem with soybeans in Kentucky, especially with the full season crop. However, under, excellent growing conditions, or if planting rates are too high, substantial lodging of double crop soybeans can also occur. If lodging occurs early during seed fill, it can reduce yields directly by causing poorer light use and increasing diseases. If lodging occurs late during seed fill, it will have little direct effect on yield, but may have an indirect effect by slowing down harvest and increasing harvest losses. Thus, the use of an inexpensive chemical to reduce soybean lodging is attractive. Our …

Effect Of Banded Fertilizer On Manganese Toxicity Of Burley Tobacco, J. L. Sims, Kenneth L. Wells, E. C. Greer

Agronomy Notes

Relatively large amounts (1500 to 3000 lbs per acre) of inorganic fertilizers are commonly broadcast preplant in the production of burley tobacco. Such high rates of fertilizer increase both the salt content of the soil solution and soil acidity, often causing reduced stands, manganese toxicity, plant molybdenum and calcium deficiencies, delayed growth and maturity, and reduced yield and quality of cured leaf. Manganese toxicity alone is thought to cost growers 30-40 million dollars each year from yield loss and the costs associated with growing extra acreage the following year to make up their quota¥ Improved fertilizer management systems are needed …

The Effect Of Oil Well Brines On Agricultural Fields And Water, V. P. Evangelou, M. Marsi, Kenneth L. Wells

Agronomy Notes

What is Brine and Where Does it Come From?
Brine is the salty water trapped in rock formations associated with oil and gas deposits. It consists mostly of sodium chloride but can also contain other things such as organics, bromide, some heavy metals and boron. Its source as a pollutant is usually oil stripper wells which produce less than 10 barrels of oil per day with typically a 10:1 ratio of brine to oil. Such wells are distributed throughout Kentucky and are often located on farmland. In some cases, brine rises to the land surface even where no oil wells …

Iron Fertilization Of Kentucky Bluegrass, David J. Wehner, Jean E. Haley

Office of the Dean (CAFES) Scholarship

Iron applications are sometimes used to enhance the color (darker green) of turfgrass stands even when iron is not deficient. A study was conducted to determine the feasibility of replacing a portion of the total yearly N applied to Kentucky bluegrass (Poa pratensis L.) with iron. Turfgrass response to iron chelate (Sequestrene 330) applications at 2.2 kg Fe ha^-1 in combination with three liquid-applied N sources (urea, Formolene, and FLUF) at 25 kg N ha^-1 was compared to turf response from applications of the N sources at 49 kg N ha^-1. Iron was substituted for …
