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 At 1440 g/10 a of boron, a decrease in seeds per pod was also involved in the yield decrease.
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.

Intervention effect Yields of the three crops were 5-18% higher under WPF.
Intervention effect Yield of sorghum and corn was 8-15% lower under BF than under PEF.
Intervention effect Soil water storage was 9-30 mm lower under BF than under PEF in sorghum and corn during the middle growth stage.
