Abstract:

To explore and develop the production potential of broomcorn millet in the arid and semi-arid region of northern Shanxi Province, different planting density and row spacing treatment combinations of broomcorn millet were plotted out to study the effects on millet yield and quality. The results showed that the yield components of the A2B3 treatment were significantly higher than the those of other treatments. At mature stage the leaf area index value of the A2B3 treatment was lower than that in the heading stage, but it was still higher than rest of the other treatments. At the mature stage, the total amount of dry matter accumulation in A3B2 and A3B3 was relatively high, 13.17g and 13.18g respectively. Comprehensive grey correlation analysis results showed that A2B3 (30cm row spacing, density of 1.05 million plants/hm 2), A3B3 (35cm row spacing, density of 1.05 million plants/hm 2), A2B2 (30cm row spacing, density of 750 000 plants/hm 2) treatment combination were suitable to be used in north region of Shanxi Province.

Key words: Millet, Row spacing, Planting density, Growth characteristics, Production, Grey relational analysis
