Effects of Fertilizer and Planting Density on Yield and Benefit of Spring Maize

Using split plot design, studied the effects of different maize special fertilizer(STANLEY compound fertilizer) and planting densities on the yield and economic benefit of Spring Maize Zhengdan 958, the results showed that the yield increased at first and then decreased with the increase of fertilization amount, in A2 treatments were the highest(750kg/ha2), 15.86t/ha2; the yield with the increasing of planting density increased at first and then decreased, in B3 treatments were the highest(7.5million lines/ha2), 16.31t/h2; Refer to the benefit of pure increase yield on density and fertilizer treatment combinations, A3B3 treatment(900kg/ha2,7.5million lines/ha2)was the highest, A2B3 treatment(750kg/ha2,7.5million lines/ha2) was the second, the benefits of pure increase yield were12600.00yuan/ha2 and 12440.00 yuan /ha2respectively; A3B3 treatment combination had the best overall performance in the comprehensive yield and benefit analysis, which could be widely applied in the test area.
