Estimating the Yield and Biomass of Maize during the Growing Season Using Satellite (Data) (A Case Study: Dasht-e-Farahan)
Nowadays, the satellite data and remote sensing technologies are widely known as efficient tools for the inspection, identification and management of land resources and precision agriculture in most countries. Satellite information could be used in supplying basic and updated information in the estimation of vegetation cover map, irrigated land area and some biological indices of the major agri...
متن کاملHistorical changes of temperature and vapor pressure deficit during the crop growing season in Iran
Climate change variables have rarely been analyzed specifically for the growing season of crops. In this study, changes in minimum (Tmin) and maximum temperature (Tmax), daily maximum saturated vapor pressure (VPsat) and estimated daily VPD weighted for transpiration (VPDtran) were examined at five locations in Iran over 40 years during the growing seasons of chickpea and maize. The results of ...
متن کاملAfrican Elephants Adjust Speed in Response to Surface-Water Constraint on Foraging during the Dry-Season
Most organisms need to acquire various resources to survive and reproduce. Individuals should adjust their behavior to make optimal use of the landscape and limit the costs of trade-offs emerging from the use of these resources. Here we study how African elephants Loxodonta africana travel to foraging places between regular visits to waterholes. Elephant herds were tracked using GPS collars dur...
متن کاملLeaf allometry of Salix viminalis during the first growing season.
We established linear and exponential relationships between leaf area (A) and leaf length (L), leaf width (W), W(2), L(2) and LW, in Salix viminalis L. Most relationships were significantly nonlinear, but good fits were obtained with both linear and exponential models. The nonlinear relationship between A and LW differed for leaves from sylleptic and proleptic shoots. Leaves from sylleptic and ...
متن کاملIncreasing Growing-season Length in Illinois during the 20th Century
Using daily minimum air-temperature (Tmin) data from the state of Illinois, the dates of spring and fall freezes – and the resulting growing-season length – are examined for trends during the period 1906–1997. Of the stations in the Daily Historical Climate Network, most show trends toward earlier spring freezes; however, trends in fall freezes are not consistent over the station network. Altho...
