Water Budget Approach to Quantify Corn Grain Yields Under Variable Rooting Depths

Water Budget Approach to Quantify Corn Grain Yields Under Variable Rooting Depths

1991). These properties include soil bulk density and chemical properties. This study investigated the relationships between corn (Zea mays An objective of site specific management is to apply L.) grain yield and weather over a range of soil rooting depths with appropriate levels of agricultural inputs to localized areas. and without irrigation. The purpose was to test if variability of corn Si...

Grain yields with limited water.

Plant reproduction is sensitive to water deficits, especially during the early phases when development may cease irreversibly even though the parent remains alive. Grain numbers decrease because of several developmental changes, especially ovary abortion in maize (Zea mays L.) or pollen sterility in small grains. In maize, the water deficits inhibit photosynthesis, and the decrease in photosynt...

ژرفای بهینه آب آبیاری ذرت در روش آبیاری بارانی

In this study, the optimum irrigation depths for corn grain production under different conditions, i.e. maximum grain yield production and maximum benefit under limited land and water conditions, were determined under sprinkler irrigation in Bajgah (15 km. north of Shiraz). The results showed that, the optimum depth of irrigation for maximum grain yield production was 77.0 cm. Because of low pr...
