Abstract
Three cropping sequences and three tillage systems were evaluated under reduced tillage. Sequences were spring `Packman' broccoli followed by `Sunny' tomatoes or 'm.s. Ky 14 × L8 tobacco, spring broccoli/tomatoes or tobacco/fall broccoli, and tomatoes or tobacco/fall broccoli. Each sequence was grown conventionally tilled/no winter cover, conventionally tilled/wheat winter cover and no-till transplanted directly into killed wheat. The study was conducted at Knoxville, (elev. 251m), Greeneville, (elev. 400m) and Crossville, (elev. 549m) during 1989 and 1990. Experiments were arranged in a strip-plot design with sequences stripped across tillages. No. 1 tomato yield was reduced in no-till at Greeneville (1989). Percentage of No. 1 tomatoes was not affected by tillage but the tomato-broccoli system produced a greater percentage at Greeneville (1990). Broccoli head size and subsequent yield was generally greater in conventionally tilled plots. Sequence generally had little affect on broccoli production. Yield and revenue of tobacco were generally lower in no-till treatments. Broccoli/tobacco sequences generally had the highest yield but varied by location. No-till produced lower quality tobacco both years at Knoxville but not at Greeneville.
