The relationship between wheat head blast incidence (I; proportion of diseased heads in a sample) and severity (S; the average area sample heads) was studied with aim determining whether could be reliably predicted from incidence. Data were collected two main sources: a) EPAMIG (non-treated) field experiments spanning seven years (2013–2019 three cultivars) designed to evaluate effect planting ...

Dual-pol Shannon Entropy captures the dynamic crop growth parameters. It was used to evaluate biophysical parameters of important crops using Sentinel-1 data. Improved phenology information is vital input crop-growth models. Mustard experienced increase as it advanced in but for wheat, decreased due absorption. A significant relationship at initial stages (height < 150 cm and biomass 5 kg m−2) ...

this study was undertaken to investigate the effect of long-term reduced tillage on grain yield, grain quality, and weed infestation of spring wheat. the experimental variables were three tillage systems: (a) conventional tillage (ct): shallow ploughing (10-12 cm) and harrowing after harvest of the previous crop, ploughing (25-30 cm) in the autumn; (b) reduced tillage (rt): only a cultivator (1...

crop density measurement is one of the most important factors in precision farming and effect onthe performance of harvesting machines such as combine and mower. so, the purposes of this studyare to design, build and calibrate of an inexpensive and non-contact instrument that can estimatecrop density for crops such as wheat, barley and alfalfa stems. the sensing unit is consisted of lasertransm...

Although spectral remote sensing techniques have been used to study many ecological variables and biotic and abiotic stresses to agricultural crops over decades, the potential use of these techniques for greenbug, Schizaphis graminum (Rondani) (Hemiptera: Aphididae) infestations and damage to wheat, Triticum aestivum L., under field conditions is unknown. Hence, this research was conducted to i...
