Influence of fertilizer treatments on stand or germination of cotton
1927
Musgrave, G.W. | Coe, D.G.
Certain relationships between fertilizer applications and resulting stands (or germination) of cotton are shown. Applications made below the seed along the row, a method commonly followed in practice, have inhibited the germination of cotton. The effect appears to be more pronounced from nitrogen and potassium salts than from phosphorus. The inhibition increased with increasing quantities of nitrogen from all sources and is more marked with applications at time of planting than with applications made prior to planting. Comparing different methods of locating the fertilizer with reference to the seed, there are several which, under the conditions of these experiments, have given results, that are fully equal to the checks. Direct contact applications are inferior and so also are concentrations of fertilizers immediately below the seed. Especially worthy of consideration (from the viewpoint of seed germination) are applications at the side of the seed row, within the cotton bed, and at approximately the same level as the seed.
