We used a randomized split plot experimental design replicated in 6 blocks (each debris-treatment main plot had four herbicide-treatment split plots).
The study was conducted for 16 months using a randomized split-plot design experiment with four replications of all combinations of treatments, the treatments being litter type and site (plantation species).
A field experiment was conducted using a randomized complete block split plot design with three drip irrigation rates (I1: 1.00, I2: 0.80, and I3: 0.60 of the estimated evapotranspiration), and three plant population densities (D1: 48,000, D2: 71,000 and D3: 95,000 plants ha−1) as the main plot and split plot, respectively.
A field experiment was conducted using a randomized complete block split plot design with four irrigation frequencies (F1, F2, F3 and F4, irrigation events once every 1, 2, 3 or 4 days, respectively) and three drip irrigation rates (I1: 1.00, I2: 0.80, and I3: 0.60 of the estimated evapotranspiration, ET) as the main and split plots, respectively.
(USDA-NRCS 2012) using a randomized complete block, split-plot experimental design with fall moisture regimes (ambient or supplemental water) applied to main plots and defoliation treatments applied to subplots.
In 2008 (year 1) and 2009 (year 2) we planted seeds monthly, September–December, in 1-m2 plots (500 seeds per plot) using a randomized block design with five replications.
This factorial experiment was arranged in a split plot using a randomized complete block design replicated three times.
In 2011 2013, 500 seeds were planted in fall, or weekly from March through early May in 1·m- 2 plots using a randomized block design with 5 replications.
3,5,6-TPA (as a free acid) was sprayed by handgun to the entire tree until the point of run off, using a randomized design with one-tree plots and 8 10 replications.
