Abstract
Soil amendments, chicken, and dairy manures have been widely used to improve soil properties as crop fertilizers. In recent years, charred material, “biochar” has been gaining acceptance in production agriculture as a soil amendment that improves soil quality, plant growth, and climate change mitigator. This study compared the combined effects of manures and biochar levels on sweet corn growth parameters. A field experiment was established at Prairie View A&M University Farm in a factorial design of two levels of biochar (2.5 and 5 t ha-1) and three levels of dairy and chicken manure (0, 224, 448 kg total N ha-1). The treatments were replicated three times. Sweet corn seeds were seeded 1 foot apart within rows and 2 feet between rows at a rate of 6.8 lb ac-1. Plant biomass, plant height, cob length, cob diameter, and height of cob from ground level were measured from all treatments. The results indicated that plant biomass did not change with manure type and rate but biochar at a rate of 5 t ha-1 had significantly greater biomass compared to control treatments after 21 days of planting. Similarly, cob length and height of cob from ground was significantly affected by manure rate. While the cob diameter was significantly affected by manure and biochar rates. No interaction effects were observed between soil amendment types, manure and biochar rates. Based on the preliminary results, the combined application of biochar and manures positively affected some of the sweet corn growth parameters: corn biomass, corn diameter.
