| Notes | 45-1381/S maize; planting density; slow-release biotic fertilizer; single fertilization （SF）; yield [Objective ] The aim of this experiment was to explore effects of planting density and fertilizer combining on the yield and its component factors of local main extended maize varieties and provide references for practical production. [Method]Complete randomized block design was applied in this experiment, three maize varieties vlz., CP619, Yumeitou 105 and Yumeitou 168 were used as test materials. Maize yield and its component factors were investigated and measured under the combinations of different planting densities （39000, 46500, 54000 plants/ha） and three fertilization modes （conventional muhi-application of compound fertilizer, single application of slow-release biotic fertilizer, and no fertilizer）. [Result]The yield of CP 619 reached the highest at planting density of 54000 plants/ha, while the yield of Yumeitou 168 and Yumeitou 105 reached the highest at planting density of 46500 plants/ha. 1000-grain w |
