Estimation of weekly potential evapotranspiration

MAUSAM, 1984
Weekly potel1tial evapotranspiration is estimated by four different methods- (A) Interpolation of monthly values estimated by modified Penman formula, (B) Estimation by modified Penman formula with weekly meteorological normals and measured net solar radiation as input data, (C) Computed following the method given by Doorenbos and Pruitt (1975) and (D)

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Estimation of Potential and Actual Evapotranspiration

Hydrology Research, 1984
A model for determining the potential and actual evapotranspiration from agricultural crops is presented. The model requires only a limited number of meteorological variables, i.e. global radiation, air temperature and precipitation. The vegetation is characterized by the crop surface area and the efficient root depth.

Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,
