Answer:
Spatial arrangement is the systematic apportioning of the farm area or any growing surface for crop production. In multiple cropping by intercropping, the intercrop can be planted in any of the following ways:
(1) within the rows of the maincrop,
(2) between the rows of the maincrop, and
(3) in replacement series (Abellanosa AL, HM Pava.
1987. An Introduction to Crop Science. Central Mindanao University, Musuan, Bukidnon, Phils.: Publications Office. p. 135-136).
Planting of the intercrop between two adjacent hills within the same row of the main crop allows interrow cultivation but the intercrop has limited exposure to sunlight. This is exemplified by the planting of peanut or mungbean between corn plants within the same row or two coffee plants that are 3 m apart between coconut plants.
Single row planting of the intercrop can also be done between the rows of the maincrop. For example, peanut or mungbean can be dibbled between two adjacent rows of corn. This system of planting arrangement is likewise common in coconut farms where fruit trees like durian, lanzones and mangosteen are grown in single rows between coconut.
In replacement series, one or more rows that are intended for the maincrop are replaced with the intercrop. For example, a 3:2 corn+mungbean intercrop means that for every 4 rows that are intended for sole corn, only 3 rows are planted to corn and one row may be substituted with 2 rows of mungbean. Another practice is in strip intercropping, for example the simultaneous growing of 6 rows corn and 12 rows soybean in alternating strips. These particular examples result to multiple row arrangement.
