“…3). Previous studies showed that nutrient enrichment by soaking seeds in macronutrient solutions had little or even a negative effect on subsequent plant growth (Scott 1989;Guttay et al 1957;Ros et al 2000). We hypothesised that the outcome of these previous studies was due to the use of inappropriate P concentrations in the solution to enrich the seed with P. By testing a wide range of P concentrations, we found that the 50 g L −1 potassium phosphate solution (approximately 0.35 M) was optimal for seed Penrichment for production of subsequent wheat shoots (Figs.…”

“…In the study, rice growth was enhanced when a larger amount of P was coated onto the seed with P-containing adhesives, implying that rice growth might require a far greater concentration for seed P-enrichment. Maize growth was suppressed when seeds were soaked in solutions that exceeded 1.8 M P (Guttay et al 1957), probably due to osmotic stress; hence, lower concentrations should have been considered. These previous and the present studies indicate that P-enrichment of seed requires soaking the seed in solutions of different P concentrations to achieve the optimum effect for different crop species.…”

Most fertilizer phosphorus (P) is sorbed by soil rather than being taken up by crops. We hypothesize enriching wheat seed with P before sowing the crop will reduce requirement of fertilizer P for subsequent wheat production. We produced Penriched wheat (Triticum aestivum L.) seed by soaking the seed in different concentrations of potassium phosphate solution. We found that 0.35 M potassium phosphate was the most effective concentration for P-enrichment of the seed. In pot and field experiments we found that the P-enriched seed required~60% less fertilizer P than seed not soaked with potassium phosphate before sowing. Increases in shoot P content could not be explained only by the increase of seed P-enrichment, suggesting that P acquisition from soil was also enhanced. Under hydroponic conditions we found that root length was greater in seedlings grown from P-enriched seed with higher specific root length than in seedlings grown from non-P-enriched seed. We conclude P-enrichment of wheat seed before sowing reduces fertilizer P requirements of plants.

“…Olson and Dreier ( 10) have recently reviewed the subject. Guttay ( 6) showed that wheat is more susceptible to fertilizer injury than oats and pointed out that phosphate in the fertilizer, in some cases, could be as injurious to germination as nitrogen or potash. Further, he showed that fertilizer placed 1 inch to the side and 1 inch below the seed did not injure the germination.…”

Effect of Seeding Rate, Row Spacing, and Rate and Placement of Fertilizer on Winter Wheat Performance in Michigan¹

Synopsis Culms per square foot, height, and vigor in the fall were much affected by seeding rate, row spacing distance, fertilizer rate, and fertilizer placement while yield, lodging score, and test weight were less affected. However, the positive correlation between fall culm count and yield in 3 of the 4 experiments emphasizes the importance of selection, of proper row spacing distance, seed rate, fertilizer rate, and fertilizer placement for producing winter wheat in Michigan.

Response of Corn to Small Amounts of Fertilizer Placed with the Seed: V. Seed Coating Compared with Banding¹

Response of corn (Zea mays L.) to a complete NPK fertilizer banded with the seed was compared with response to the same fertilizer coated on the seed before seeding in the greenhouse. Fertilizer was more efficient in its effect on P uptake and growth of seedlings when coated on the seed than when banded with the seed. It was more toxic, however, than banded fertilizer. Thus a greater growth response was obtained with banded fertilizer at rates which did not seriously delay or reduce emergence than could be obtained with the lower rates required for similar emergence when fertilizer was coated. In attempts to reduce the toxicity, a number of compounds were coated on the seed before the fertilizer was added. Sucrose and polyvinyl acetate reduced the toxicity of coated fertilizer appreciably, but probably not enough to make seed coating a practical method of fertilizing corn.
