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.

Cc90-342 Soil Compaction...Fact And Fiction: Common Questions And Their Answers, Alice J. Jones, Robert D. Grisso, Charles A. Shapiro

University of Nebraska-Lincoln Extension: Historical Materials

What causes soil compaction? Compaction occurs when soil particles move closer together because of external forces exerted by humans, animals, equipment and water droplets. It can be found on the soil surface and at almost any depth. Compacting soils leads to conditions that are less than optimum for crop growth, soil water management and efficient use of agricultural chemicals.

Ec90-1762 Nut Tree Cultivars For Nebraska, William A. Gustafson Jr.

University of Nebraska-Lincoln Extension: Historical Materials

Proper nut cultivar (variety) selection is important for successful and satisfying results from the home gardener's efforts. Selection should be determined by personal preferences, available space, and intended use of the nuts. Harvest can be spread over several weeks if cultivars with different periods of maturity are planted.

It is important that homeowners select the nut plants or cultivars best adapted for cultivation in their area of the state. This extension circular covers how to select a nut cultivar, the plant hardiness zones, horticultural regions, and length of growing season. It contains a list of all nut cultivars suited for …

G90-963 Narrow-Row Soybeans, Roger Wesley Elmore, Russell S. Moomaw, Roger Selley

University of Nebraska-Lincoln Extension: Historical Materials

Narrow-row spacing of soybeans may be a profitable practice with modern herbicides and new lodging-resistant varieties. This NebGuide describes considerations for producing narrow-row soybeans. Early in this century crop row spacing was determined by the breadth of the animals used to work the fields. Spacing had an impact on methods of weed control and the varieties of soybeans developed. Even a decade ago row spacing was determined by tractor tire size since cultivation was required. Also, the tall varieties of soybeans lodged severely in narrow-row systems. However, the broad spectrum of herbicides now available and lodging-resistant soybean varieties have made …

G90-992 Evapotranspiration (Et) Or Crop Water Use, Norman L. Klocke, Kenneth Hubbard, William L. Kranz, Darrell G. Watts

University of Nebraska-Lincoln Extension: Historical Materials

What must irrigators consider in the most efficient use of water? Read on.

Irrigators in the Great Plains have two major challenges in the years ahead:

1. Maintain groundwater quality by adjusting management to minimize the leaching of agri-chemicals from the crop root zone;

2. Continue profitable production in the face of a less abundant and increasingly costly water supply.

Irrigators must learn to convert water to grain the most efficient manner possible. Applying only enough water to meet full evapotranspiration (ET) of the crop is one key to efficient water use (ET is also called crop water use.)
