Abstract

In nature and in the most primitive agricultural systems, seed distribution
is broadcast across the landscape. Such a distribution results in nearly uniform
spacial interaction of the developing phytomass. With the development of
agrarian civilization has come an implement-dependent systemization of crop-
planting patterns. This has brought about the planting of crops in uniform
rows—from the drilling of small grains at inter-row spacings of 0.1 to 0.2
m and plant intra-row spacings of i to 5 cm, to the staking of horticultural
and vine crops at 2- to 3—m inter-row spacings and typically 0.3- to l-m intra-row spacings.

The implement dependence of agricultural cropping strategies has
resulted in row cropping. The staple crops regarded as most suited to this
approach are commonly called row crops, and this review will concentrate
largely on how row crops interact with plant geometry, water, and nutrients
to influence sustained productive capacity.
