Growth, Yield, and Nitrogen Accumulation by Sesame (Sesamum indicumL.) grown in North Central Florida. |

Sesame has the potential to be a new agronomic crop for Florida with important drought tolerant and nematode resistant properties. However, because commercial production in FL began in 2012, little is known about the crop’s phenology, physiology, nutrient uptake patterns in this semi-tropical environment. Research was initiated at the University of Florida’s Plant Science Research and Education Unit in Citra, Florida to evaluate six commercial varieties and six experimental varieties for physiological plant characteristics such as yield, leaf area index (LAI), root growth, and dry matter accumulation. Root architecture will be evaluated in situ using minirhizotron imaging throughout the season. In addition, the amount of nitrogen accumulated in sesame during the 2013 and 2014 growing seasons will be quantified using total Kjeldahl nitrogen (TKN) for the above ground biomass of one experimental and three commercial sesame varieties at five times during the growing season. TKN will also be measured for the below ground biomass for two of the three commercial varieties. Soil samples will be taken throughout the season to determine the available nitrogen in the soil. A nitrogen budget will be completed based on the data collected. |
