Evaluation of peanut seed treatments in west Texas, 2008.

摘要

A field trial was conducted at the Texas Tech University Quaker Research farm located in Lubbock, TX. The soil was a Brownfield sandy clay loam that had no history of seedling disease. Soil temperature was 64.2 deg F at a 6 in. depth on the day of planting (16 May), with adequate soil moisture. To increase disease pressure, plots were artificially infested with ground oat seed colonized by Rhizoctonia solani (3 grams per seed packet). Plots (two 40-in. rows by 35.5 ft) were arranged in a split-plot design with four replications.Whole plot treatments consisted of seed treatment and inoculation (natural or artificial) served as sub-plots. All production practices followed Texas AgriLife Extension Service recommendations. Stand counts were recorded on 6 Jun, 13 Jun, and 20 Jun. Vigor ratings were made 20 Jun. Plots were inverted on 16 Oct and harvested 23 Oct. Data were analyzed using the ANOVA procedure of SAS, and means were separated usingFisher’s protected LSD (P<0.05).
