Abstract
The present work was carried out to study the main effects of using Municipal waste water as source of irrigation to Oryza Sativa L. (Rice) and Abemolchus Esculent L. (Okra) from El-keblia Drain in Antoniadis -Kafr Eldawar district El-Behera Governorate on some eco-physiological parameters including some growth criteria, yield and heavy metals concentration in soil and (roots ,shoots and grains) of rice as well as the concentration of the heavy metals in (roots-branches-leaves-legumes) of okra and compare the results with the same plants in the same conditions but irrigated by freshwater.
The concentrations of elements attained their maxima in soil irrigated with municipal (Type I) for rice and okra crop except for Cd in the later compared to Type II. Regarding element ratio in rice and okra, Al attained a maximum of about 83.4 and 83.8 mg/g for the two plants, respectively. Likewise, the highest values of 44 and 61.6 mg/g were attained for P in the soil underneath the two plants. It is currently known that the most visible effect of using wastewater for irrigation is a productivity increase due to its content of nutrients and organic matter.
The variation in the length and ratios of length (cm) of rice roots and shoots as well as number of tillers in rice during summer 2020 from two locations (I: irrigated with municipal wastewater and II: irrigated with freshwater. For Type 1 roots attained length of about 19.6 cm compared to 13.0 for Type II. Regarding shoot it attained about 121 cm and 102cm in Type I and Type II respectively. Obviously the number of tillers attained about 18.6 and 8.8 in Type I and Type II respectively. Commonly, length attained their maxima in roots, shoot as well as number of tillers in rice (Type I) compared to roots, shoots as well as number of tillers in rice (Type II).
Yield and yield components of okra have been illustrated in the present study. In the variation in the length and ratios of length (cm) of okra roots and branches as well as number of nodes in okra during summer 2020 from two locations (I: irrigated with municipal wastewater and II: irrigated with freshwater. For Type 1 roots attained length of about 25 cm compared to 16 for Type II. Regarding branch it attained about 134 cm and 92cm in Type I and Type II respectively. Obviously the number of nodes attained about 28 and 17 in Type I and Type II respectively. Commonly, length attained their maxima in roots, Branches as well as number of nodes in okra (Type I) compared to roots, branches as well as number of nodes in okra (Type II).
