IMPACT OF DRIP AND GATED PIPE IRRIGATION SYSTEMS, INTERVALS ON YIELD, PRODUCTIVITY OF IRRIGATION WATER AND QUALITY OF TWO COMMON BEAN (PHASEOLUS VULGARIS L) CULTIVARS IN HEAVY CLAY SOIL
Autor: Ibrahim El_metwally, Noura Taha
Publikováno v: Egyptian Journal of Chemistry.
Two field experiments were conducted during the two successive winter growing seasons of 2018/2019 and 2019/2020 at Kafer El-Khawazim, Talkha district, Dakahlia Governorate, Egypt to study the effect of irrigation systems (drip and gated pipe) and ir

A modified topology achieved in OFDM/SAC-OCDMA-based multi-diagonal code for enhancing spectral efficiency
Autor: Bedir Yousif, Ahmed S. Samra, Ibrahim El. Metwally
Publikováno v: Photonic Network Communications. 37:90-99
In this paper, a modified topology-based orthogonal frequency division multiplexing–spectral amplitude coding in optical code division multiple access (OFDM–SAC-OCDMA) has been introduced. Such analysis aims to explain the effect of spectral effi

Response Of Wheat (Triticum aestivum L.) Crop And Broad-Leaved Weeds To Different Water Requirements And Weed Management In Sandy Soils
Autor: Ibrahim El_metwally, Oussama Mounzer, Mohamed Abdelmonem, JUAN JOSE ALARCON, Abdelraouf Abdelghany, Magdi Abdelhamid, Mohamed Ahmed
Publikováno v: Agriculture, Vol 61, Iss 1, Pp 22-32 (2015)
Water scarcity is a major cause of crops yield reduction in many parts of the world. So, a more rational use of irrigation water should be adapted and deficit irrigation principles should be accepted with a certain level of reduction in yield level.
