in order to evaluate the response of russian knapweed seeds to cardinal temperatures a factorial experiment was conducted base on completely randomized design with 3 replications. russian knapweed seeds (collected from irrigated and rainfed wheat fields), and germination temperatures (constant temperatures of 10, 15, 20, 25, 30 and 35° c) were used as first and second levels of the experiment. ...

abstract rainwater harvesting (rwh) is one of the most effective water resources management techniques for confrontation with water shortage condition. rwh which is basically known as a traditional method, has been developed rapidly and being used widely in dryland countries throughout the world. rwh is defined as collecting and storing rainwater from nearby catchment and delivering it to plant...

Genetic analyses and association mapping were performed on a winter wheat core collection of 96 accessions sampled from a variety of geographic origins. Twenty-four agronomic traits were evaluated over 3 years under fully irrigated, rainfed and drought treatments. Grain yield was the most sensitive trait to water deficit and was highly correlated with above-ground biomass per plant and number o...

the sunn pest, eurygaster integriceps put. is an important pest of wheat in firozabad region of ardabil province, iran. in this study the spatial distribution of overwintered adult was investigated in rainfed wheat fields. then, fixed precision sequential sampling plan was developed and validated for estimating overwintered adult density. iwao's patchiness regression gave a better fit to d...

poor wheat stand establishment is a major cause of yield loss, particularly in rainfed and poorly irrigated environments. seeds of eight wheat cultivars (triticum aestivum l.) including irrigated and rainfed varieties, belonging to three different climates of iran (hamedan as cold, karaj as temperate and sarpolzohab as warm climates) were primed using osmoprimig treatments through use of urea ,...

Effect of Plant Growth Regulators on Soluble Carbohydrates, Photosynthetic Pigments and Chlorophyll Fluorescence Sirvan Homa Wheat Cultivars in Rainfed Irrigation Conditions

The concept of stability is important for the selection crop Cultivars and in breeding programs. aim this work was to evaluate productivity some bread wheat cultivars under rainfed conditions different locations NWCZ Egypt. Results current study showed that studied performed differently environment and. AMMI analysis revealed responsible most yields variation also AMMI2 bi-plot East Barrani fir...

Drought significantly reduces yield of many crop plants including wheat in the world. Identification of wheat genotypes that can thrive on limited water is vital to boost the wheat production of rainfed areas. Forty wheat genotypes were screened for drought tolerance using 0, 7.5, 15 and 22.5% Polyethylene Ethylene Glycol 6000 solutions at PMAS Arid Agriculture University, Rawalpindi, Pakistan ...
