Evaluation Of Secondary And Micronutrients For Soybean Production In Kansas, M. N. Gutierrez, D. A. Ruiz Diaz
Evaluation Of Secondary And Micronutrients For Soybean Production In Kansas, M. N. Gutierrez, D. A. Ruiz Diaz
Kansas Agricultural Experiment Station Research Reports
Study of secondary and micronutrients is growing because of their potential contribution to yield increases. The objective of this study was to evaluate soybean response to secondary and micronutrient fertilizer application to maximize yields. A randomized complete block design was employed with four replications at five locations during 2013 and five locations in 2014. Treatments consisted of an unfertilized control; micronutrient fertilizer as individual nutrients for boron, copper, manganese, sulfur, and zinc; and a mix of these nutrients using two different placements (dry broadcast and liquid band). Soil samples were collected prior to planting and after harvest. Soybean trifoliates were …
Corn Response To Foliar-Applied Zinc Fertilizers, A. Lamb, N. O. Nelson
Corn Response To Foliar-Applied Zinc Fertilizers, A. Lamb, N. O. Nelson
Kansas Agricultural Experiment Station Research Reports
This study was conducted to determine corn response to three foliar-applied zinc sources. The study was conducted on dryland corn in Manhattan, KS, during the 2014 growing season. Yields were low as a result of very low precipitation during pollination and grain fill. There was no yield response to foliar-applied Zn; however, grain analysis show significant increases in grain Zn concentration from foliar-applied Zn. Foliar-applied Zn products are effective for increasing Zn uptake in corn. Additional studies need to be conducted to determine the yield response.
