“…We hereby discuss the impact of one of those innovative management practices, aimed at a more efficient use of nutrients in Agriculture: their direct application to the seeds via a coating technique. In the particular case of soybean seeds, the effect of several nutrients on seedling establishment and yield has been studied in the literature: phosphorus 1,2 , potassium 3 , zinc 4 , cobalt 5 and molybdenum 6 . In the study presented herein, the impact of calcium, magnesium and silicon is studied for two soybean genotypes.…”

“…compounds (Figure 2). These results indicate that the seed coating with molybdenum compounds improved the impaired establishment of seedlings flooded for a few days, as well as in the rice seeds (Hara, 2013c) and soybean seeds (Hara, 2015) sown in flooded condition.…”

“…However, the seedling establishment under a non-flooded condition seemed to be inhibited by coating with a molybdenum compound above .1 mol-Mo kg −1 (Figure 4). The inhibition under a non-flooded condition was also observed for soybean (Hara, 2015). Coated molybdenum compound around seeds elutes soluble molybdate ions.…”

Wheat and barley are often cultivated also in paddy fields in winter in Japan. The drainage of paddy fields is often poor. The seedling establishment of wheat and barley is more prone to become poor if it rains heavily after sowing. The flooding damage on seedling establishment is thought to be caused by many factors. The generation of sulfide ions in flooded and reduced soil is thought to be one factor of the flooding damage. In this study, the effect of seed coating with molybdenum compounds, which suppress the generation of sulfide ions, on the flooding damage of wheat and barley seedling establishment. Two poorly soluble molybdenum compounds were coated on wheat or barley seeds at different amounts. Coated seeds were sown in soil and soon flooded for 2 d at 20 °C. When seeds were not coated with molybdenum compounds, rates of seedling establishment were no more than 32%. However, when any molybdenum compounds of .05-.5 mol-Mo kg −1 were coated, seedling establishment was significantly improved and rates of seedling establishment were no less than 54%. However, when sown seed were not flooded, the establishment rates of the seeds, which were coated with a molybdenum compound of no less than .1 or .2 mol-Mo kg-1, were significantly decreased. Accordingly, coating of molybdenum compounds could improve the seedling establishment of coated seeds under flooded condition, but might impair the seedling establishment of coated seeds under unflooded condition.

“…Water drainage is often poor in paddy fields and may negatively affect seedling establishment of these upland crops, especially if it rains heavily after sowing. Seed coating using poorly soluble molybdenum compounds improved seedling establishment for wheat, barley (Hara, 2016), and soybean (Hara, 2015), under flooded conditions.…”

Seed coating with molybdenum compounds improves seedling establishment for rice, wheat, barley, and soybean when such seeds were sown under flooded conditions. Tungsten belongs to the same chemical group as molybdenum in the periodic table, and similar to molybdenum, inhibits the generation of sulfide ions. Here, the effects of tungsten and molybdenum containing seed coatings on seedling establishment under flooded conditions were compared using rice, wheat, barley, and soybean. In rice, the effects of tungsten compounds on seedling establishment varied. Tungsten trioxide had little effect but tungstic acid and ammonium phosphotungstate significantly improved seedling establishment when the amounts were at least .1-.2 mol W kg −1. Although the effect of tungsten coating varied depending on the compound used, ammonium phosphotungstate, along with other tungsten compounds, improved seedling establishment in a manner comparable with that of molybdenum compounds. For wheat and barley, ammonium phosphotungstate treatment resulted in a significant increase in establishment that was only slightly less than the results observed using molybdenum compounds. Tungstic acid and ammonium phosphotungstate treatments improved soybean establishment in a significant manner that was comparable with those of molybdenum compounds. Collectively, these results suggest that tungsten compounds, as well as molybdenum compounds, improve seedling establishment under flooded conditions.
