Many squash varieties are large-seeded and may be well-suited for planting under no-till production systems. A study was done at the Rutgers Agricultural Research and Extension Center in Bridgeton, N.J., to evaluate the yield and loss of soil when butternut squash (BS) ( Cucurbita moschata  `Waltham') was grown using no-till (NT), strip-till (ST), and bare ground (BG) tillage systems. The soil was a Sassafrass gravely sand loam and the field had a 3% slope. A cover crop mixture of hairy vetch and winter rye planted on 23 Sept. 1998 using a Brillion seeder at a rate of 136.2 kg/ha and 610.2 kg/ha, respectively, was used to create the NT and ST plots. NT and ST plots containing the cover crop mixture were killed with Glyphosate and chopped using a Buffalo stalk chopper on 27 May. BG plots were tilled clean before planting and ST plots were rototilled to a 30.48 cm band to establish a seedbed. BS seeds were hand-planted on 7 July with a spacing of 38.1 cm between plants and 182.9 cm between rows. Irrigation was applied overhead at a rate of 6.28 cm/ha weekly. Erosion was measured using inverted pans over the soil area to be measured. Harvest took place on 21Oct. and yields included only marketable fruit with the following results: NT = 8.65 t/ha; ST = 8.99 t/ha; BG = 4.06 t/ha. Yields in the NT and ST plots were significantly higher than yields in the BG plots. Soil erosion measurements were taken on 21 Oct. Soil loss results from the plots were 0.08 cm (NT), 0.84 cm (ST), and 3.33 cm (BG). Soil loss, mainly due to water erosion, was significantly higher in the BG plots. BS yields can be significantly higher when using alternative tillage systems like NT and ST. When using NT and ST systems for the production of BS, soil erosion is reduced
