Effects of Herbicide-Resistant Technology Fees on the Plant Population Decision for Cotton Production
This study evaluated effects on cotton net revenues of four herbicide-resistant technology policies used since 1996 by Monsanto. Results indicate that farmers may have an incentive to switch from narrow-row to wide-row cotton and to use a lower plant density when the technology fee is tied to the seeding rate.Farm Management,
OPTIMAL PLANT POPULATION FOR ULTRA-NARROW-ROW COTTON PRODUCTION AS INFLUENCED BY LINT AND TRANSGENIC SEED PRICES
Farmers are concerned about the high costs of transgenic seed and technology fees associated with the large plant population densities recommended for ultra-narrow row cotton. This study evaluated the effects of alternative plant population density decision criteria on net revenues under different lint price and transgenic seed cost scenarios. Results indicate that farmers may be able to maximize profits by seeding for a target plant population density of approximately 15.5 plants m-2.Crop Production/Industries,

Foliar feeding cotton: Evaluating potassium sources, potassium solution buffering, and boron.
ABSTRACT on soils having Mehlich-1 extractable K of 177 kg ha ĎŞ1 or less. Yield response to foliar K continued through were not increased by applying K to a soil having 193 solutions to pH 4 resulted in 10% higher yields than the check or kg extractable K ha ĎŞ1 . unbuffered K solutions. Adding a surfactant (ethoxylated alkyl aryl The foliar-applied K source may also affect yield rephosphate esters) to KNO 3 resulted in 5% higher yields then the sponse to foliar fertilization. Burmester (1995) reported that lint yields were instudy, these treatments should return 8 to 10 times the product costs

Herbicide-Resistant Technology Price Effects on the Plant Density Decision for Ultra-Narrow-Row Cotton
Farmers are concerned about the high cost of planting herbicide-resistant cotton with the high plant densities recommended for ultra-narrow-row cotton. This study evaluated the effects on net revenues of four herbicide-resistant technology fee policies used since 1996 by Monsanto, the technology license holder. Results indicate that changes in the technology fee policy by Monsanto have raised the cost of planting herbicide-resistant cotton. As a consequence, farmers may have an incentive to switch from ultra-narrow-row cotton to wide-row cotton and to use a lower plant density when the technology fee is tied to the seeding rate

Comparing the Value of Soil Test Information Using Deterministic and Stochastic Yield Response Plateau Functions
We determined the value of soil test information for potassium (K) in upland cotton production
using the linear response plateau (LRP) and linear response stochastic plateau (LRSP) functions. A
stochastic dynamic programming model was used to determine the net present value to K fertilizer
when optimal K was applied with knowledge about K carryover. Using K carryover information
for K application decisions increased net present value and helped maintain steady levels of soil
K. The LRSP function fit the data better than the LRP, and the value of soil testing was $27 ha-1
lower over ten years using the LRSP
