Post‐harvest drone flights to measure weed growth and yield associations
نویسندگان
چکیده
Abstract Drone flights are often only performed during the growing season, with no data collected once harvest has been completed, although they could be used to measure winter annual weed growth. Using a drone mounted multispectral sensor, we flew small plot corn ( Zea mays L.) fertility, cover crop, and population studies at black layer 0–14 d after (DAH). Yields had positive correlations normalized difference vegetation index (NDVI) but negative yields DAH. After harvest, NDVI associated growth, yield point reduced canopy allowing light reach late‐season weeds. In fertility studies, excess nitrogen appears increase biomass which can easily identified through imagery. Flights should as growth may provide additional insight into management decisions.

ABSTRACT- Crop residue is applied to amend soil properties and increase crop yield. In this study, the effects of rapeseed residues and different rates of nitrogen on grain yield and yield components of sunflower and weed dry matter were investigated. The experiment was conducted at the Experimental Farm of College of Agriculture, Shiraz University, located at Badjgah, Shiraz, Iran in 2007-2008...

Management of nitrogen fertilization in crops is one of the most important components of integrated weed management. A two-year field experiment was conducted to determine the direct effects of wild mustard aboveground biomass and N content of wild mustard on oilseed rape yield. A set of factorial treatments was arranged in a randomized complete block design with four replications. Treatments w...

Growth and yield response of potato genotypes to deficit irrigation
In Ardabil region potato crop needs several irrigation, however ground water supplies arebeing exhausted due to reduced precipitation and intensive irrigation. In this research droughttolerance of 10 commercial potato cultivars was studied at three irrigation treatments (100%,80% and 60% of required irrigation water) in Ardabil in a two years field study, 2013-2014.At harvest, marketable tuber ...
