Tillage Intensity In A Long-Term Wheat- Sorghum-Fallow Rotation, A. Schlegel
Tillage Intensity In A Long-Term Wheat- Sorghum-Fallow Rotation, A. Schlegel
Kansas Agricultural Experiment Station Research Reports
Grain yields of wheat and grain sorghum increased with decreased tillage intensity in a wheat-sorghum-fallow (WSF) rotation. In 2015, available soil water at wheat planting was greater for no-till (NT) and reduced till (RT) than for conventional till (CT). Similarly, for grain sorghum in 2015, available soil water at planting was increased with NT or RT and least with CT. Averaged across the 15-yr study, available soil water at wheat and sorghum planting was similar for RT and NT and about 1 inch greater than CT. Averaged across the past 15 years, NT wheat yields were 5 bu/a greater than …
Effects Of Phosphorus On No-Till, Minimum-Till, And Conventional Till Irrigated Field Corn, John A. Mckay
Effects Of Phosphorus On No-Till, Minimum-Till, And Conventional Till Irrigated Field Corn, John A. Mckay
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This investigation involved three tillage treatments, fall plowed (conventional) (moldboard IS-centimeter depth), fall chiseled (ripped) (25-centimeter depth), and no-tillage (zero tillage) replicated four times on an established alfalfa field. Rye was planted in the fall and harvested prior to planting the corn. Soil samples contained an average of 5.9 ppm phosphorus in the 0-30 centimeter soil layer, indicating the need for additional phosphorus. Within each tillage treatment, six rows received 11 kilograms/hectare phosphorus with the seed and 34 kilograms/hectare phosphorus side-dressed. Six rows received 45 kilograms/hectare phosphorus side-dressed, and four rows received 0 phosphorus. All 16 rows received 64 kilograms/hectare …
