Soybean
Row Spacing, Plant Population, Planting Date and Water Management
|
| Paul Jasa,
UNL Extension Engineer ; Jim Specht, UNL Professor of Agronomy
and Horticulture |
- Learn
how to increase available soil water by reducing runoff and evaporation
- Observe
row spacing, population and planting date influences on plant
development
- Understand
the yield components of number of plants, seeds per plant, and seed size
- Learn
about water needs for the various plant growth and seed development
stages
|
Profitability
comes from developing the proper balance between increasing yields,
while reducing input costs.Before making changes, producers need to
understand how the soybean plant develops and what the components of
yield are.You also need to know how the plants respond to population
density, both within the row and between rows, and how the plant
development changes with planting date. Once you understand plant
growth, then you can manage your production system to make the most
efficient use of available water and sunlight to maximize profitability. |

- Soybean
root growth and nutrient uptake
- Starter
fertilizer use for high-residual no-till production
- Nitrogen
application at early seed fill for high yield soybean
- Improving
recovery of applied phosphorus
|
New
problems continue to make soybean production in Nebraska more
challenging. At this stop we will cover the most recent and
significant problems affecting production from the pest management
perspective (Diseases, Insects and Weeds).

| Nutrient
Management Issues for Soybean Production |
Charles
Wortmann, UNL Extension Soils Specialist
Ray Ward, Co-Owner and President, Ward Laboratories |
- Soybean
root growth and nutrient uptake
- Starter
fertilizer use for high-residual no-till production
- Nitrogen
application at early seed fill for high yield soybean
- Improving
recovery of applied phosphorus
|
Practical
aspects of soybean root growth and nutrient uptake will be addressed at
this stop. Learn about nitrogen availability with high residue
conditions, nitrogen availability during the reproductive stage when
biological N fixation may fail to meet the N requirement of high yield
soybean, and management for improved fertilizer P recovery. |

| Making
Crop Yield and Price Decisions |
| Steve
Johnson, Farm & Ag Business Management Specialist, Iowa State
University Extension Terry Hejny, UNL Extension Educator |
- Estimating
Your Soybean Yields
- Considering
Storage and Marketing Decisions
- Implementing
the 2007 Commodity Farm Program
- Managing
Crop Revenue Risk
|
At this
field stop, we’ll take a hands-on approach to learn how the
USDA estimates soybean yields, while learning to calculate
transportation and storage costs. Make important marketing decisions
that will allow you to develop a plan for financial change. |
