Effect of terminal bud clipping on growth and yield of soybean cultivars in the Pacific Northwest

Soybean [Glycine max (L.) Merr.] is one of the four major staple crops and world's most important vegetable protein source. Very little information available on performance, yield, cultivars soybean when choosing a cultivar to grow in Pacific Northwest (PNW). Of oilseed crops, appears have best potential be grown at profit (high yields) PNW considering high input costs for irrigated crops. The present study was conducted determine if terminal bud clipping would increase yields under conditions 2-year field experiments. Five were planted four-row plots with rows 0.13 m apart. Plots replicated times two treatments (early late clipping) control randomized complete block design. Data regarding yield growth traits recorded using standard procedure. significantly influenced by year production clipping, whereas showed no effect. Early resulted 15% 18% 2018, 16% 2019 compared control. Terminal shorter plants reduced lowest pod height, lodging, maturity Lodging decreased late-maturing cultivars. Finally, results suggest that increases yields. maturing (maturity group 0.4) are unsuitable due height.
