The effect of soil on Ammi visnaga (L) Lam. plant grown in several localities of Egypt and Sudan

This study shows the effect of soil structure, soil texture and different types of nutrients on the growth of Ammi visnaga (L.) Lam, as well as the yield of the fruit crop and its content of the main active principals (ɣpyrones). The study was carried out in several localities in Two Arabian countries in North Africa; Egypt and Sudan. Egypt: at three localities:-1st at Mepaco Farm in Enshas El-Raml, Sharkya Governorate, the2nd at Al-Alfy Farm in Dakahlia Governorate, while the 3rd in Assuit Governorate in Upper Egypt. Sudan: the first locality is in Abo Halema farm, 20 km North Khartoum city, the second locality is in WadRaml, about 60 Km North Khartoum. Source of seeds, the time of seeding, schedule of irrigation, thinning and collection were all fixed. So; the only differences were: the Farmers care for soil and plants as well as soil characteristics. Soil samples were subjected to elemental analysis to analyze their content of essential (Macro and micro) nutrients, non-essential nutrients as well as non-mineral nutrients. Soil PH, bulk and taped densities were also determined. The number of plants per Fadden, number of umbels per plant, number of rays per umbel and number of fruits per ray were determined. The yield of fruits per Fadden, fruit characteristics and the percentage of total and separate ɣ-pyrones were also determined and recorded.
