چکیده
ABSTRACT Second-crop maize-ruzigrass (Urochloa ruziziensis) intercropping, nitrogen (N) fertilization, and high maize plant densities enhance biomass production N cycling, which may favor soybean growth yield in the following season. This study aimed to assess effects of second-crop top dressing, density on straw autumn/winter, agronomic performance crops grown succession. Field experiments were installed 2018/2019 2019/2020 seasons using a randomized complete block design with split-split plots four replications. The factors investigated: cropping system (sole intercropped ruzigrass), dressing (0 80 kg ha-1), (40, 60, 80, 100 thousand plants ha-1). Maize-ruzigrass intercropping improved (2,365 ha-1) cycling (50 increased season (232 fertilization grain by 180 ha-1. Maize did not influence succeeding crops, regardless growing

The Effect of Intercropping of Maize and Soybean on Microclimate
Intercropping induces the diseases decreasing, and yield increasing, may partly due to the improvement of microclimate in fields. In order to understand the mechanism and efficiency of resource utilization in intercropping of maize (Zea mays) and soybean (Glycine max), a field experiment was conducted as factorial on the bases of randomized complete block design of three patterns with three rep...
متن کاملArbuscular mycorrhizal fungi and rhizobium facilitate nitrogen uptake and transfer in soybean/maize intercropping system
The tripartite symbiosis between legumes, rhizobia and mycorrhizal fungi are generally considered to be beneficial for the nitrogen (N) uptake of legumes, but the facilitation of symbiosis in legume/non-legume intercropping systems is not clear. Therefore, the aims of the research are as follows: (1) to verify if the dual inoculation can facilitate the N uptake and N transfer in maize/soybean i...

Nitrogen uptake and transfer in a soybean/maize intercropping system in the karst region of southwest China
Nitrogen (N) deficiency occurs in over 80% of karst soil of southwest China, which restricts regional agricultural production. To test whether N fixed by legumes becomes available to nonfixing companion species, N fluxes between soybean and maize under no, partial, and total restriction of root contact were measured on a karst site in southwest China. N content and its transfer between soybean ...
