Abstract
The dataset includes detailed field experiments from four locations across a temperature gradient along the River Nile. The data covering four contrasting environments from North (low temperature) to South (high temperature), includes Sakha (North delta, lower Egypt), Menofya (Middle delta), Benisuef (Middle Egypt) and Aswan (upper Egypt). Measurements included plant density, aboveground biomass, anthesis and maturity dates, grain yield, grains m-2, kernel weight and N content in grains as well as daily weather data (solar radiation, maximum and minimum temperature, precipitation, surface wind, relative humidity, dew point and vapor pressure) and soil characteristics and crop management. Wheat was sown under full irrigation and fertilization with two planting dates. Simulations include three DSSAT-Wheat models (CERES, NWHEAT and CROPSIM).
Highlights
1 INTRODUCTION: Detailed field experiments were conducted during three growing seasons (2011–12 to 2013–14) at four locations along the River Nile
Additional details on the data obtained through observation and / or simulation are supplied in the supplementary which is provided with Asseng et al 2018
2 MODELS CALIBRATION AND EVALUATION: Three wheat crop models comprised in DSSAT v4.7 – i.e. CERES, NWHEAT and CROPSIM - were tested (Jones et al 2003, Hoogenboom et al 2017)
Summary
Detailed field experiments were conducted during three growing seasons (2011–12 to 2013–14) at four locations along the River Nile. The selected locations range from North (moderate temperature) to South (high temperature) and included Sakha (north delta, Lower Egypt), Menofya (middle delta), Beni Suef (Middle Egypt), and Aswan (Upper Egypt). The field experiments were conducted using the most common modern wheat cultivars Sakha, Misr, and Misr under full irrigation and fertilization. Two planting dates were adhered to: 20 November (recommended) and 30 November (late, to expose wheat to increased seasonal temperatures). Clac.edu.eg) collected daily weather data at the four locations of the experiments. These represent all agroclimatic zones in Egypt, with grain yield ranging from 4.2 to 9.0 t/ha. Additional details on the data obtained through observation and / or simulation are supplied in the supplementary which is provided with Asseng et al 2018
