Abstract

Effects of different irrigation rate and fertilizing rate on the productive performance of Trifolium pratense cv.Minshan were studied.The results showed that the fresh yield had extremely significant correlation with hay yield.The height had remarkable correlation with hay yield,heights had remarkable negative correlation with branch numbers.The correlation between forage yield and branch numbers was extremely low.Increasing irrigation rate(1 000 m3/hm2)and fertilizing rate(P2O5 360 kg/hm2+ K2O 90 kg/hm2)could get more branches and higher forage yield for the no P fertilizer and irrigation pasture.Irrigating rate could be relevantly reduced(500 m3/hm2)if the P fertilizer application rate was increased(P2O5 120 kg/hm2+ K2O 90 kg/hm2)and high branch numbers and forage yield could be achieved.The effects of irrigation and fertilizing on height were not significant.
