Maize (Zea mays L.) is one of the most important crops in the world. In this study, 13 agronomic traits of a recombinant inbred line population that was derived from the cross between Mo17 and Huangzao4 were investigated in maize: ear diameter, ear length, ear axis diameter, ear weight, plant height, ear height, days to pollen shed (DPS), days to silking (DS), the interval between DPS and DS, 1...

Planting maize (Zea mays L.) reasonably densely and adding amounts of appropriate nitrogen fertilizer are essential measures to improve the efficiency yield use. In this study, two planting densities 7.5 × 104 plants ha?1 12.0 were established with varieties DengHai 618 (DH618) XianYu 335 (XY335). Simultaneously, 18 levels application established, including a lack (N0) increments 45 kg up 765 (...

In previous investigations of several maize cultivars, an improvement the harvest index was obtained by paclobutrazol (PAC) application combined with increase in water-use efficiency. However, so far nutrient-utilization efficiencies could not be enhanced when control and PAC-treated plants received same amount fertilizers. With adjusted fertilizer supply according to lower requirement smaller,...
