Cover crop interseeding effects on aboveground biomass and corn grain yield in western North Dakota

چکیده

Including cover crops in established crop rotations can enhance the delivery of ecosystem services from agricultural lands. Inclusion rainfed cropping systems northern Great Plains, however, is challenging due to short growing season, limited precipitation, and variable weather conditions. Cover interseeding row has been proposed as one approach address these challenges. A 3-yr study was conducted near Mandan, ND evaluate effects planting time on weed aboveground biomass subsequent corn grain yield. Treatments included a no control planted at advancing vegetative growth stages (1st planting=V4, 2nd planting=V6, 3rd planting=V8), replicated 4-6 times each year. Across years, greatest 1st (393 lb/ac), least (Mean = 212 intermediate (247 lb/ac). treatments had significant effect yield any year, suggesting that will not reduce under conditions like those observed this study. Limited competition weeds likely contributed outcome, production low. Future research western North Dakota should consider forage value biomass, winter survival different crops, spacing This article protected by copyright. All rights reserved

MODIS-based corn grain yield estimation model incorporating crop phenology information

a r t i c l e i n f o A crop yield estimation model using time-series MODIS WDRVI was developed. The main feature of the proposed model is the incorporation of crop phenology detection using MODIS data, called the " Shape-Model Fitting Method ". MODIS WDRVI taken 7–10 days before the corn silking stage had strong linear correlation with corn final grain yield at both field and regional scales. ...
