Title: Effects of Planting Density and Nitrogen Applications on Grain Yield and Quality of ZHENMAI168
Abstract: Zhenmai168 is a first strong gluten and red-seeded wheat cultivar in southern Huaihe River in Jiangsu Province,which exhibited strong gluten quality,high yield potential,strong resistance to diseases and environment.In order to explore suitable cultivation measures for the large-scale of wheat cultivar,Zhenmai168,the effects of different planting density,nitrogen fertilizer level and their interaction on its yield and quality were investigated in this study.The results showed that effective spikes,yield,dough development time,stability time,crude protein content and volume weight rose first and then dropped as plant density increases of Zhenmai168,however,grains per panicle,1000-grain weight and wet gluten content reduced gradually.When nitrogen application amount was 240 to 330kg·hm-2,the increase of nitrogen would improve wheat yield,affect its components,and improve quality indices of crude protein content,wet gluten content and volume weight as well.Under this condition,in order to get high yield and good quality,the optimal combination of density and nitrogen applications were 270 × 104plants.hm-2and 330kg·hm-2,respectively,for Zhenmai168.
