Simple Stations mod provides you structures which can be used to automate single crop farming. Station works according to the selected filter (seed or crop) which is not consumed. This mod is made to help in industrial mod packs.
For stable work you need water only - 1 bucket per cycle
One cycle takes 20 realtime minutes and produces a big batch of crops at the end Work time can be shortened with power (redstone or RF) to 8.3 minutes with fertilizer (bone meal) to 4 minutes with both to 2.5 minutes
Stations needs a single seed to start batch producing
Structure takes 3x3x1 space.
