- W2373338475 abstract "In order to investigate the effects of staging fertilization on the growth and yield of different corn varieties in alluvial soil in the east of Henan province,the effects of traditional fertilization and different nitrogen amount in topdressing stages(180kg/ha,270kg/ha,360kg/ha,amount of nitrogen topdressing in small horn stage and booting stage was 50%respectively)on growth and yield of eight corn varieties were studied in Tongxu county,of which corn varieties including Xiandan 158,Zhengdan 958,Zhongbo Zhengdan 23,Jidan 7,Liyu 16,Xundan 20,Liyu 37 and Dika M9.The results showed that compared to traditional fertilization,there was positive effect on corn growth with staging fertilization,the number of visible leaves of Xiandan 158and Xundan 20increased 1-2leaves,the plant height of different varieties increased 2.7cm to 83.6 cm,the stem diameter increased 0.1cm to 0.6cm except Xundan 20,and their rows per ear,grain number per spike,ear length,ear diameter and 100-grain weight were obvious different too.Compared to traditional fertilization,the yield of staging nitrogen topdressing 180kg/ha increased overall by 0.23%to 34.42%,the yield of staging nitrogen topdressing 270kg/a and 360kg/ha increased by 1.63%-32.35%,0-14.60%respectively,except Jidan 7and Liyu 16,indicating that the demand of nutrients of different corn varieties had obvious difference;compared to staging nitrogen topdressing 180kg/ha,only the yield of Xundan 20stably increased 0.48%and 2.34%respectively under staging nitrogen topdressing 270kg/ha and 360kg/ha,which indicated that Xundan 20had certain yield-increasing effect at the higher fertilizer;compared to staging nitrogen topdressing 270kg/ha,the yield increased 0.97%to 8.43%except Xiandan 158,Zhongbo Zhengdan 23and Dika M9.In a word,the effect of production increasing with staging nitrogen topdressing 180kg/ha is the best,and the best varities are Zhengdan 958,Liyu 37and Xundan 20in different fertilization according to the yield stability performance of different varieties." @default.
