Tillage and Nitrogen Placement Effects on Yields in a Short-Season Corn/Wheat/ Double-Crop Soybean Rotation

In 2016, adding nitrogen (N) greatly improved average wheat yields, but the response to tillage and different N placement methods was minimal. Double-crop soybean yields were unaffected by tillage or the residual from N treatments that were applied to the previous wheat crop.

Timing of Side-Dress Applications of Nitrogen for Corn in Conventional and No-Till Systems

Corn yields were affected by tillage and nitrogen (N) side-dress options in 2016. Corn yields were 12% greater with conventional tillage than with no-till. Side-dress applications of N at V10 resulted in greater corn yield than side-dress N applications at V6.

Response of Soybean Grown on a Claypan Soil in Southeastern Kansas to the Residual of Different Plant Nutrient Sources and Tillage

Soybean yields measured from 2014 through 2016 were more than 50% greater from the residual from N-based turkey litter applications during 2011 through 2013 than in the control where no nitrogen (N) or phosphorus (P) was applied. However, residual from P-based turkey litter applications or fertilizer-only did not result in soybean yield different from the no N-P control. This ...

Nitrogen, Phosphorus, and Potassium Fertilization for Newly Established Tall Fescue

Tall fescue production was studied during a third year at two locations. In 2015, Site 1 was affected by an interaction between nitrogen (N) and phosphorus (P) fertilization rates; while in 2016, Site 2 mainly received production differences by N fertilization rates. Potassium (K) fertilization caused little effect at both sites. Third-year production of tall fescue was affected by ...

Tillage and Nitrogen Placement Effects on Yields in a Short-Season Corn/Wheat/Double-Crop Soybean Rotation

Conventional tillage resulted in greater corn yield in 2015 than with reduced tillage or no-till. A tillage × N fertilizer treatment interaction showed that N placement did not affect corn yield in conventional or reduced tillage systems, but subsurface knife N placement in no-till resulted in greater yield than when N was surface-applied.

Use of a Fungicide to Reduce Stomatal Conductance in Sweet Corn Planted at Different Populations with Limited Irrigation

In 2015, increasing seeding rates increased the number of harvested sweet corn ears; however, total fresh weight did not increase above 22,500 seeds/acre. Sweet corn was little affected by limited irrigation or a fungicide applied for stomatal control.

Timing of Side-Dress Applications of N for Corn in Conventional and No-Till Systems

In general, conventional tillage averaged nearly 40 bu/acre greater corn yield than no-till likely because of improved growth during the season. With conventional tillage, all side-dress treatments resulted in greater yield than with all N applied pre-plant. However, in lower-yielding no-till systems, the yield response to side-dress applications appeared to be greater for V10 ...

Response of Soybean Grown on a Claypan Soil in Southeastern Kansas to the Residual of Different Plant Nutrient Sources and Tillage

The residual from previous high rate turkey litter applications, which were based on N requirements of the previous grain sorghum crop, increased soybean yield above that obtained from the residual of P-based turkey litter applications (low rate), commercial fertilizer, or the control. Even though early soybean growth was not significantly affected by residual treatments, the ...

Response of Soybean Grown on a Claypan Soil in Southeastern Kansas to the Residual of Different Plant Nutrient Sources and Tillage

The residual effects of turkey litter and fertilizer amendments applied in previous years had little effect on the yield, yield components, and dry matter production of the following soybean crop grown in 2014.

Surface Runoff Characteristics from Claypan Soil in Southeastern Kansas Receiving Different Plant Nutrient Sources and Tillage

Preliminary results show that two-year average total nitrogen (N) runoff losses and ortho-phosphorus (P) and total P runoff losses in the second year were greater with N-based turkey litter/no-till applications than P-based turkey litter or fertilizer-only applications. Incorporation of turkey litter applied based on N requirements resulted in N and P losses that did not differ ...

Response of Wheat to Residual Fertilizer Nitrogen Applied to Previously Failed Corn

When drought conditions result in poor corn growth and yield, the potential exists for carryover of fertilizer nitrogen (N) to wheat. Soil sampling at the wheat jointing stage showed that NO3-N levels increased slightly as previous N rate increased up to 240 lb/a N, but did not appear sufficient for the wheat yield increase to previous N rate. The relationship between wheat ...
