Understanding tillage, N, and P interactions can contribute to improved N and P utilization and crop response. This study examined the interaction effects of tillage and N rate of two N sources on N and P uptake by corn (Zea mays L.). The study was conducted on Kenyon loam (fine loamy, mixed, mesic Typic Hapludolls) soil at the Iowa State University Northeast Research and Demonstration Farm nea...

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...

Farmers in the tropics and subtropics of Asia usually transplant rice seedlings puddled soils which makes crop establishment weed control easier. But can be grown successfully by planting into non-puddled after a single shallow pass strip tillage. This method was globally reported to produce same yield as traditional puddle farming saved labor, fuel water, too. With this aim asses effect tillag...
