Autor: H. M. El Sharkawi, I. M. Hashem, E. S. Naeem, T. F. Metwally

Publikováno v: Journal of Plant Breeding and Crop Science. 8:34-44

Lodging of rice in Egypt reduces production and may be related to the agronomic practices. A 2-years field experiment was conducted at the Experimental Farm of Rice Research and Training Center, Kafr El-Sheikh, Egypt, during two growing summer season

EFFECT OF NITROGEN FORMS AND RATES ON SOME HEAVY METALS AVAILABILITY AND RICE PRODUCTIVITY UNDER WASTEWATER IRRIGATION

Autor: H. M. El Sharkawi, B. A. Zayed

Publikováno v: Journal of Plant Production. 3:173-190

Water shortage in rice cultivation area in Egypt pushed rice farmer to use poor quality water in rice irrigation. Using the correct nitrogen form with the proper rate might be coping with the condition and possible heavy metals in such water. Two fie

Trifactorial interactive effects of nutrients, water potential and temperature on carbohydrate allocation to the embryonic axis of desert plant seeds

Autor: S.A. Sayed, K. A. Farghali, H. M. El‐Sharkawi

Publikováno v: Journal of Arid Environments. 35:655-664

Seeds of Prosopis juliflora, Calotropis procera and Sorghum × drummondii seeds were subjected to trifactorial treatment combinations of: nutrients (Nr), temperature (T) and reduced water potential (ψ m ) in their incubation medium. The embryonic ax

Effects of drought and salinity on some growth-contributing parameters in wheat and barley

Autor: H. M. El‐Sharkawi, F. M. Salama

Publikováno v: Plant and Soil. 46:423-433

This study is mainly concerned with some parameters contributing to growth as indicators of difference in drought resistance and salt tolerance of wheat and barley cultivars. Parameters made use of are: transpiration efficiency (‘dry matter/transpi

Autor: F. M. Salama, A. A. Fayed, H. M. El‐Sharkawi

Publikováno v: Feddes Repertorium. 93:125-133

Torrential rains (in January 1980) that had suddenly swept a limited area in the eastern desert facing Qena Province (Upper Egypt) resulted in enriching the vegetation of some extremely dry wadies at this location. Vegetation survey carried out short

Response of Olive and Almond Orchards to partial irrigation under dry-farming practices in semi-arid regions

Autor: M. El-Monayeri, H. M. El-Sharkawi

Publikováno v: Plant and Soil. 44:113-128

The response of elements of the water balance of olive plants grown in desert farms to partial irrigation was investigated. Among these are transpiration, leaf relative water content, the number of leaves carried by trees and the osmotic pressure of
