Abstract: 【Objective】To explore the effects of different row spacing configurations on agronomic traits,yield and quality of millet in western Henan,and to provide reference for high-yield cultivation technology in western Henan.【Methods】Field experiments were conducted using the main cultivated varieties Yugu 18 and Tiansu 10 in the region as materials. The agronomic traits,yield and nutritional quality of millet were analyzed by using a completely random block design and three row spacings,namely T1(23 cm+43 cm),T2(16 cm+50 cm)and equal row spacing T3(30 cm+30 cm).【Results】The plant height,leaf length and leaf width of Yugu 18 reached the maximum values of 103.90,39.46 and 3.28 cm under T2 treatment,respectively,and the plant height and leaf width were significantly higher than those of other treatments(P<0.05);the internode length under panicle reached the maximum value of 13.06 cm under T2 treatment. Stem diameter,spike length,spike diameter and yield reached the maximum values under T1 treatment,which were 9.23 mm,21.17 cm,19.56 mm and 4 636.80 kg/hm2,respectively. Plant height,leaf length,leaf width,stem diameter,spike length,spike diameter and yield of Tiansu 10 reached the maximum values of 112.00 cm,45.80 cm,3.07 cm,8.77 mm,23.17 cm,17.60 mm and 4 680.40 kg/hm2 under T1 treatment,respectively. The internode length under panicle reached the maximum value of 14.07 cm under T2 treatment. The path analysis showed that the most influential factor on the yield of Yugu 18 was spike diameter(0.485),followed by spike length(0.209). Spike diameter(0.527),followed by stem diameter(0.348),had the greatest impact on the yield of Tiansu 10. Grey correlation analysis showed that the importance of different row spacing to the nutritional quality indexes of Yugu 18 and Tiansu 10 was ranked as carbohydrate> crude protein>crude fat>crude ash>crude fiber.【Conclusion】 When the yield is the goal,the row spacing of millet in western Henan is T1(23 cm+43 cm),which can increase the ear diameter;When the goal of nutritional quality is T2(16 cm+50 cm),the row spacing is preferred,which can improve the nutritional quality.
