Abstract/Contents:"There exists the relation y = y(x) = w(x) [N0 + q(x) x], where x = nitrogen dose, q = apparent recovery of fertilizer nitrogen, N0 = amount of nitrogen present in the harvested plant matter in case of x = 0, w = internal efficiency of nitrogen taken up, and y = dry matter yield. The possibilities for improving q by way of plant breeding are rather limited because cultivated grasses usually take up almost the entire amount of available nitrogen. On the contrary, improvement of the internal efficiency w by breeding procedures offers much better opportunities. It may occasionally be useful to combine such improvement with increased nitrogen fertilization, the more so as w is strictly in the inverse ratio to the crude protein concentration of dry matter."
