Drought is a major factor limiting growth and development of crops such as mung bean (Vigna radiate (L.) wilczek) in arid and semi-arid regions of the world. This study was conducted to investigate the effects of different timing and severity of drought stress on physiological traits of mung bean and its relation to grain yield. A field experiment was carried out during 2004 growing season at E...

Phenology is a broad science topic of Ecology. Study of phenology for regulating of animal grazing programs and determining of palatability and nutritive value of plant species at different stages of vital in range is important. This study was carried out to determine the chemical composition and nutritive value of Salsola vermicolata and Suaeda fruticosa that are halophyte plants, in three phe...

The effects of irrigation water salinity (12 dS m−), imposed at maximum tillering (35−40 days after sowing, DAS) or booting (50−60 DAS) or grain filling (75−85 DAS) stage of wheat, on growth and yield of the crop was demonstrated. The experiment comprised four treatments – I1: irrigation by fresh water (FW) at all three growth stages (control), I2: irrigation by saline water (SW) at maximum til...
