Abstract:
The effects of planting density on the stem elongation,distribution of pod and seed,yield and yield components of summer soybean under drip irrigation were studied.Treatments were established following one factor and randomized block design.The result showed that the number of pods,seedless pods and seeds per plant declined with the increasing density.The effect of planting density on variations of the number of pods and seeds were significant in upper and lower layers,but not in middle layer.With the increasing of planting density,plant height and internode length increased,while the grain density and stem diameter decreased.The difference in grain density was up to 63.16% due to plant density.The yield showed a downward parabola against planting density.It found that 5.25×105plants per hectare had the highest yield of 3 205.04 kg·ha-1,which reached a very significant difference(P<0.01)compared to the other treatments.
