Abstract
Agricultural system is currently undergoing uprising in political social shift to form a sustainable agricultural system with the aim of providing adequate ecological biodiversity and food production. Weeds are wild plants grow in an environment without the contribution of any human activities that that have positive or negative impact to the environment. The study aims at carrying a survey on weeds of family Amarantheceae grown in cultivated environment with purpose of recording and identification. the study was conducted in the Taif region of Saudi Arabian kingdom in a mountain with an elevation level of (Area A = Al sail 1700 m, Area B = Al Wahat and Al Watit 1500, C = Leeih 1500, D = AL Gaim and Saisad 1500, F = E = Al Shafa 2200 m, F = AL Hada = 2000 m). The study was conducted between December 2018 to August 2019. The study was carried out based on enviromental survey. Diverse number of weeds were identified and collected from the examined study area. Results revealed 10 aggressive weeds species. hybridus 407, Amaranthus viridis 382, Chenopodium murale ,Chenopodium album 142, Chenopodium vulvaria 81, Amaranthus graecizans 32, Chenopodium 39, Atriplex leucoclada 30 ,Chenopodium opulifolium 15, Aerva javanica 3. Similarly, eight agricultural crops were documented from the study area; Brassica oleracea var, botrytis 159, Solanum melongena 54, Petroselinum sp 165, Ficus carica 178, Lactuca sativa 27, Punica granatum 12, Vitis spp 43 and Brassica oleracea 56 respectively. Results of the survey obtained from the study would be useful in creating management control and proposing research toward improved new weed control measures. Also has provided insight on purposeful weeds control in Taif Area. The study recommends further studies on order types of weeds in the area.
