Paper Summary

The study aimed to find the best N and K fertilizer ratio for spring rapeseed in eastern Qinghai Province. They tested different fertilizer amounts and found that N2P2K1 treatment had the highest yield. The optimal N and K fertilizer amounts were determined to be N 170.71 kg/hm2 and K2O 88.14 kg/hm2, resulting in the highest yield of 5 746.59 kg/hm2. It was suggested that N 170.00 kg/hm2 and K2O 85.00 kg/hm2 are the recommended fertilizer amounts for spring rapeseed in the region.
