Corn and soybean replant decisions

Written by William Wiebold (Professor Emeritus, Plant Science and Technology Extension), Ray Massey (Professor, Agricultural Business and Policy Extension)"Deciding whether to replant a sparse stand is one of the more difficult decisions a corn or soybean grower will face. The difficulty of this decision stems from the difficulty of predicting how the effectiveness of replanting will be affected by the combination of planting date and changing environmental conditions. However difficult, replant decisions are made by at least some Missouri farmers every year. This guide provides a step-by-step procedure for estimating dollar gain or loss from replanting. This procedure involves a careful study of the field in question and an analysis of its yield potential."--Page 1.William Wiebold (Professor Emeritus, Plant Science and Technology Extension), Ray Massey (Professor, Agricultural Business and Policy Extension).New 4/1999; Revised 6/202

Corn and soybean replant decisions

Deciding whether to replant a sparse stand is one of the more difficult decisions a corn or soybean grower will face. The difficulty of this decision stems from the difficulty of predicting how the effectiveness of replanting will be affected by the combination of planting date and changing environmental conditions. However difficult, replant decisions are made by at least some Missouri farmers every year. This guide provides a step-by-step procedure for estimating dollar gain or loss from replanting. This procedure involves a careful study of the field in question and an analysis of its yield potential. Follow these steps: 1. Determine the cause of the sparse stand. 2. Determine the stand density and condition of the stand. 3. Determine the yield potential of the sparse stand. 4. Estimate the expected gross revenue from the sparse stand. 5. Estimate the cost to replant. 6. Estimate the yield potential and gross revenue from a replanted stand. 7. Determine whether replanting will pay for itself.William Wiebold (Extension Professor, Division of Plant Sciences), Raymond Massey (Extension Professor, Department of Agricultural and Applied Economics and Commercial Agriculture Program)Reviewed November 2018 -- websit

Missouri 2011 Soft Red Winter Wheat Performance Tests

This report is published by the MU Variety Testing Program, Division of Plant Sciences, University of Missouri. The work was supported by fees from companies and organizations submitting varieties for evaluation. The large number of varieties available makes selection of a superior variety difficult. To select intelligently, producers need a reliable, unbiased, up-to-date source of information that will permit valid comparisons among available varieties. The objective of the MU Variety Testing Program is to provide this information. Tests are conducted under as close to uniform conditions as possible. Small plots are used to reduce the chance of soil and other variations occurring among variety plots. Results obtained should aid individual growers in judging the relative merits of many of the commercial wheat varieties available in Missouri

Drought-related issues in forage, silage and baleage

Many producers are now searching for alternative feeding options for livestock. In addition to safety and herd health issues, these factors affect the business decisions for each operation. In response to producers’ concerns, University of Missouri Extension has developed this list of producers’ questions answered by extension crop and forage specialists

Drought-related issues in forage, silage and baleage

"Drought often changes the composition of forages. Issues such as nitrate accumulation and reduced nutritive value often cause problems for farmers using drought-damaged forages. Many producers are now searching for alternative feeding options for livestock. In response to producers' concerns, University of Missouri Extension has developed this list of producers' questions answered by extension crop and forage specialists."--Page 1.Eric Bailey (Beef Extension Specialist), Joe Horner (Agricultural Economics Specialist), Robert Kallenbach (Forage Production and Management Specialist), Ray Massey (Agricultural Economics Specialist), Craig Roberts (Agronomy Specialist), Peter Scharf (Agronomy Specialist), William Wiebold (Agronomy Specialist

Missouri 2011 Corn Performance Tests

This report is published by the MU Variety Testing Program, Division of Plant Sciences, University of Missouri. The work was supported by fees provided by companies submitting hybrids for evaluation. The University of Missouri's hybrid performance testing program began in the mid-1930s, with results first published in 1937. The number of entries in the program has grown from fewer than 50 in the early years to more than 250 today. The large number of commercial hybrids available makes selection of a superior hybrid difficult. To select intelligently, producers need a reliable, unbiased, up-to-date source of information that will permit valid comparisons among available hybrids.
