Abstract: The aim was to explore the effect of seed manure on no-tilling and precision sowing summer maize. Two field tests with five treatments (NPK, NP, NK, PK and CK) of seed manure were conducted to determine the physiological parameters and yield index in 2013. Under the treatment of NPK seed manure, the seedling quality, root dry weight, root volume, root number, leaf Pn and SPAD were all the best, thus reduced the bald tip of maize ear length, increased the maize ear length, ear row number, row grain number, and 1000 kernel weight. The yield of NPK treatment increased by 4.52%, 6.06%, 13.21% and 29.05% in comparing with that of treatment NP, NK, PK, CK, respectively. The yield-increasing effect of NPK treatment was greater than that of the other fertilizer combinations. Seed manure affected seeding effect of no- tilling and precision sowing summer maize. At the same time, N, P and K were essential nutrients of seed manure for no-till and precision sowing summer maize.
