Excerpt from A Contribution to Agricultural Botany: Being Lessons From Turnip Singling If 3 pounds of seed are sown at equal intervals on an acre of 27-inch drills, there will be plants, each having a space to grow in of little more than half an inch. These plants will each have room to attain a. Weight of nearly half an ounce, making the total weight upon an acre about six tons. Experience has shown that fewer and larger plants will give a greater total weight. And the question how many fewer and how much larger will give the greatest possible weight? Is a purely experimental question, to be answered only by actual experiment. If, then, a turnip will not attain its greatest size in a lineal space of half-ah-inch, there must be a lineal space in which a turnip will attain its greatest size. Let this length of drill, in which, under ordinary profitable cultivation, a turnip will attain its average maximum weight, be called the maximum individual unit. With the largest possible turnips growing at intervals of this unit, the balance will inform us what is the collective weight upon an acre.
