Historically preparing cottonseed for planting purposes involved the use of an acid delinting process, which allows the seed to flow in a single seed manner required for planting. This process is very effective and inexpensive, yet it could potentially be very hazardous to the seed, workers and the environment. This study evaluates the performance of a polymer starch coating applied to partially mechanical delinted fuzzy cottonseed as an alternative method of preparing cottonseed for planting purposes. The seed treatments were evaluated in the field comparing the performance of acid delinted seed to that of the alternative polymer starch coated seed. This study was performed in a large scale plot trial using a producers land and equipment. The following data were collected: Cool Germination Test - CGT, Warm Germination Test -WGT, Cool Warm Vigor Index - CWVI, Seed Index, Seeding Rate, Establishment Percentage - EP, Emergence Rate Index - ERI, and Lint Yield. There was no significant difference between the acid delinted and coated seed in the CGT and WGT 4 and 10 DAP. There was however a significant difference in the CWVI which was probably due to a slightly slower rate of imbibition by the coated seed. There was also a significant increase in seed weight of the coated seed. This was due to a combination of residual linters and the coating that was applied to the seed. In the field parameters tested we observed no difference in the seeding rate between the coated seed and the acid delinted seed. The coated seed did have a lower actual number of seeds planted per acre but this was not significantly different from that of the acid delinted seed. The EP and Final Stand count did not show a significant difference between the two treatments. For the ERI there was no difference, but we did see the same trend as in the laboratory where the coated seed had a lower absolute number, possibly due to a slightly slower rate of imbibition by the coated seed. For the Lint Yield parameter we observed no difference between the acid delinted and coated seed. From this one study conducted at one location in 2004 we observed no difference between the performance of the acid delinted and starch coated seed. [ABSTRACT FROM AUTHOR]
