Effect of Heterodera glycines and soil chemical and biological cultivation factors on the yield of green soybean grown in a glasshouse in Japan
Nematology 19 (2), 237-244
Abstract: Yellowing symptoms sometimes cause yield losses in green soybean cultivation. The objective of this study was to estimate the yield loss factors in a glasshouse. The parameters evaluated were plant-parasitic nematodes (Heterodera glycines, Pratylenchus penetrans, Meloidogyne spp.) and soil chemical properties. While the density of H. glycines did not show a negative correlation with yield in the February planting date, it showed a strongly negative correlation in the March planting date. Multiple regression analysis showed that yield was significantly correlated with P. penetrans and nitrate in the February planting, and with H. glycines and K in the March planting. The present study revealed that yield loss was caused by P. penetrans and nitrate in seasons with unsuitable temperatures for H. glycines hatch, and by H. glycines and alleviated by K in seasons with optimum temperatures for H. glycines hatching.
