growth and yields. Plots were planted to cassava intercropped with maize. Soil accumulation by VGH serving as barriers to trap eroded soil was significantly affected by the spacing. Gravimetric moisture content increased with wider alley spacing
and infiltration characteristics were improved in the alleys. Maize grain yields were significantly increased by vetiver alleys. Areas of land taken out of cultivation by grass increased with time. Thus, a balance needs to be struck between the number of hedges

This study firstly simulated the potential and waterlimited yield of summer maize in the Beijing-Tianjin-Hebei (BTH) region using WOFOST model with meteorological data of 40 years, and then analyzed yield gaps between the actual and potential yield
of rainfed summer maize to reduce the pressure on water resource.

The fertilizer experimental site used in this study was established on a maize field in Shenyang Agriculture University in 1987. The treatments included, CK : unfertlized control, M : organic manure, N : inorganic N fertilizer and MN : combination
increase in degree of grain yield to the N and MN treatments, therefore it could be the best option for improving soil productivity and C storage in the maize cropping system.

A study was conducted to evaluate the effect of tillage method and depth on grain yield and irrigation water use efficiency (IWUE) of maize during the dry season at Dire Dawa, eastern Ethiopia, in 2005-2006. It was found that increasing till depth
The AA. present paleoecological data from the archaeological site of Cobá, which provides evidence bearing on lowland Maya development. Palynological and geochemical data record multidecadal precipitation cycles. Maize cultivation allowed the Maya
to develop a complex society and support a large population, but dependence on maize was ultimately doomed by variable rainfall. Precipitation in extreme years was insufficient to support crops, while native vegetation was not directly affected by drought
annual precipitation and rain periods gave no clear trends over the study period. Results from analysing the growing seasons for maize, the main annual crop, and periods during which maize plants are sensitive to drought showed decreasing trends
