Study on the Effect of Sowing Date and Fertilizer on Growth and Yield Components of New Soybean Variety Henong 63

Taking new soybean variety Henong 63 as test material,the effect of different sowing date and fertilizer on leaf area dynamics,dry matter accumulation and yield components were studied.The results showed that the effect of early sowing and late sowing on soybean growth were inferior to normal sowing,the vegetative growth would be inhibited in early sowing,the growth period of late sowing date was shorter than normal sowing date,the two both affected the accumulation of dry matter.There were no obvious difference on plant height between early and late sowing date and normal sowing date,on average,the early sowing was a little more than late and normal sowing.The plant pods,plant seeds,100-seed weight and yield would be lower than those of normal sowing.It could draw a conclusion that it should be planted around May 8th in Jiamusi region,which would lead to average yield 14.3% higher than those early sowing and 16.7% higher than those late sowing.
