abstract

Spacing of plants affects both the total yield and the size of broccoli heads according to recent field tests. These results are important because the freezing industry generally prefers heads of smaller size than those shipped for fresh marketing. The tests indicate that the closer the spacing, the smaller the heads produced. Total yield increased to a maximum when spacing was reduced to 8 or 11 inches (depending on season and variety). Further decrease in the space between plants results in an abrupt reduction in yield.
