Effects of Boron Application on Seed Yield and Yield- Related Traits in Kidney Bean

Ichi SASAKI; Takuya KITABATAKE; Toshiki MATSUI; et al. Japanese Journal of Crop Science 2026. doi:10.1626/jcs.95.104

Other claims from this paper (15)

Intervention effect In trial 1, the FTE plot (citrate-soluble boron) raised kidney bean yield by 12% over the untreated plot (mean of cultivars and years).
Intervention effect In trial 1, the Agri-Ace plot (citrate-soluble boron and zinc) raised kidney bean yield by 9% over the untreated plot.
Intervention effect In trial 1, the water-soluble plot (water-soluble boron and zinc) raised kidney bean yield by 14% over the untreated plot.
Intervention effect Yield did not differ with or without zinc in the fertilizer materials.
Association Post-harvest soil content of boron alone showed a significant positive correlation with yield.
Mechanism The yield increase is considered to come from increased boron uptake.
Intervention effect At Ebetsu, yield peaked at boron application rates of 360-720 g/10 a.
Intervention effect At Obihiro, yield peaked at a boron application rate of 720 g/10 a.
Intervention effect Yield decreased at boron application rates of 1080 g/10 a or more.
Intervention effect The yield increase at the optimum boron rate relative to the untreated plot was mainly due to an increase in node number.
Intervention effect The yield decrease at 1080 g/10 a or more of boron was mainly due to fewer pods per node.
Observation At Ebetsu, post-harvest soil boron content exceeded the upper diagnostic limit of 1.3 ppm at 1080 g/10 a or more.
Observation At Obihiro, post-harvest soil boron content exceeded the upper diagnostic limit of 1.3 ppm at 1440 g/10 a.
Recommendation Applying about 360-720 g/10 a of boron is recommended as effective for increasing kidney bean yield.
Recommendation At this rate boron accumulation is not worrying, and continued application to kidney bean in a 3-4 year rotation is considered unproblematic.

Method / resource The facility power consumption was 80% lower than that of Free Air Temperature Increase.
Method / resource The facility built a 25 m2 homogeneous heating area.
Intervention effect The facility had little effect on relative humidity in a paddy field.
Intervention effect Warming treatments significantly reduced rice grain yield by 4.4–22.7% in 2015 compared with the control.
Intervention effect Warming treatments significantly reduced rice grain yield by 30.8–61.9% in 2016 compared with the control.
Mechanism A reduction of 1000-grain weight led to a decline in grain yield.
Method / resource The increasing ranges of the temperature simulated by HBWF were stable across years.
Association Differences among elevated treatments in rice growth were mainly decided by the basic atmospheric temperature.
Recommendation The new warming facility is suitable for field trials assessing elevated temperature combinations.

Chad L. Kimmelshue; A. Susana Goggi; Kenneth J. Moore Crops 2022. doi:10.3390/crops2010006

Other claims from this paper (6)

Association Seed placement (sowing depth) was crucial to uniform corn emergence in both cropping systems.
Intervention effect Seed size did not affect corn emergence in either cropping system.
Intervention effect The perennial groundcover (PGC) cropping system delayed corn emergence compared with bare soil.
Intervention effect The PGC cropping system reduced corn grain yield by as much as 50% compared with bare soil.
Association Single-plant corn yield decreased with delayed emergence in both cropping systems.
Mechanism The yield decrease with later emergence is likely related to post-emergence environmental factors.
