2.3. Year 1 experiment
In year 1, a chisel plow and middle buster were used to prepare
the field in May 2011. The field was then irrigated and solarized for
1.5 months with clear greenhouse plastic in order to reduce weed
pressure. Upon removal of plastic, a row-maker was used to make
three 1.5m long rows per replicate for a total of nine rows. Drip
tape was installed down the center of each row during the rowmaking
process.
