Behavior and fate of chlorpyrifos introduced into soil-crop systems by irrigation.

Assessing SALTMED model for wheat experiments irrigated with basin and sprinkler systems

Comprehensive agricultural models are crucial for assisting several decision makingprocesses due to their capability for use under different conditions. SALTMED is a holisticgeneric model, which simulates yield, dry matter and soil water content under differentirrigation managements and systems. The aim of this study was to calibrate the SALTMEDmodel to simulate wheat yield, dry matter and soil...

Photodegradation of Insecticide Chlorpyrifos in Aqueous Solution under Simulated Solar Light Irradiation Conditions using Babolrood River Water

Chlorpyrifos is an organophosphate insecticide, used to control foliage and soil-borne insect pests on a variety of food and feed crops. In the natural environment, Chlorpyrifos can be degraded  through  several  possible  processes,  including  photodegradation, biodegradation,  and hydrolysis.  In  the  present  work  the  photodegradation  and  environmental  fate  of  Chlorpyrifos  in aqueo...

Parametrizing Simple Model between Yield and Evapotranspiration for Amaranthus cruentus under Drip and Sprinkler Irrigations

Amaranthus cruentus, an annual vegetable crop, is known to be highly productive under rain-fed conditions and during the dry season when supplied with water. However, for good water management, there is need to accurately quantify the water consumed by the crop. This paper investigates the water use and biomass yield of differentially irrigated Amaranthus cruentus at different developmental sta...

Mitigation Strategies for Reducing Aquatic Toxicity from Chlorpyrifos in Cole Crop Irrigation Runoff

Reviewing the harvest index estimation in crop modeling

H Harvest index (HI), ratio of seed yield to aboveground dry matter, is a very important parameter for estimating seed yield in several crop models. In this study, the importance, definition, variability and estimation methods of HI in crop models were discussed. HI estimation methods are categorized into two groups including: (i) complex methods that estimate HI from the beginning of seed gro...
