Zonal management of cereal–legume cover crop mixtures may help address weed and nitrogen challenges common in organic reduced tillage systems. During a field study conducted over 3 years Michigan, we evaluated the effects management, tillage, supplemental mulch on organically produced acorn squash ( Cucurbita pepo ). fall season before production, rye Secale cereale L.) vetch Vicia villosa Roth...

Conservation tillage and even no tillage as a practice is not new. However, there appears to exist evidence that in some cases no-tillage is successfully incorporated into a new concept of truly sustainable agriculture, gaining popularity as “conservation agriculture” all over the world. Conservation Agriculture is, besides no-tillage and direct planting, based on very old concepts such as gree...

the recent decades emphasis on reducing pesticide use especially herbicide has led to increased interest in alternative weed control methods. the purpose of this study was to evaluate the hilling time and simultaneous interseeding of two cover crops as living mulch to control weeds in potato and to determine the impact of these actions on potato yield. a randomized complete block design as spli...

Residual herbicides and cover crops are important tools inside an integrated weed management program. The straw produced in crop rotation can interacts with herbicides. aim of this study was to evaluate the interaction diclosulam, sulfentrazone, imazethapyr, flumioxazin, s-metolachlor pyroxasulfone black oat, cereal rye, common vetch oilseed radish it´s reflection on control soybean p...

Soil N2O emissions from three corn (Zea mays L.)-soybean [Glycine max (L.) Merr.] systems in central Iowa were measured from the spring of 2003 through February 2005. The three managements systems evaluated were full-width tillage (fall chisel plow, spring disk), no-till, and no-till with a rye (Secale cereale L. 'Rymin') winter cover crop. Four replicate plots of each treatment were establishe...
