c     ac0rg  - Crop seeding location in relation to ridge
c         0     o plant in furrow
c         1     o plant on ridge

c     acdpop - Crop seeding density (#/m^2)

c     acntil - typical tillering factor for crop
c
c              range values      min        max

c              ------------   ---------  ---------

c     acytgt - target yield (in units shown below)
c     achyfg - flag indicating part of plant which is harvestable yield
c         0     'yield' is all of the 'reproductive' mass
c         1     'yield' is a fraction of the 'reproductive' mass
c         2     'yield' is all or a fraction of the aboveground biomass
c         3     'yield' is all or a fraction ofthe leaf mass
c         4     'yield' is all or a fraction ofthe stem mass
c         5     not used at the moment

c     acynmu - string for name of units in which yield of interest will be
c              reported
c     acycon - conversion factor from Kg/m^2 to units named in acynmu (all
c              dry weight)
c     acywct - water content at which yield is to be reported

c     acrsfg - row spacing flag
c         0      o Broadcast Planting
c         1      o Use Specified Row Spacing
c         2      o Use Existing Ridge Spacing

c     acxrow - Crop row spacing (m)

c     acthud - heat units or days to maturity flag
c         0      o Days to maturity and average conditions used to find heat units
c         1      o Heat units specified used directly
