Effect of bio-fertilization and salinity levels of irrigation water on the growth and yield traits of wheat

Abstract

A field experiment was conducted for the winter season 2018 in the wire canopy belonging to Al-Furat Al-Awsat Technical University, Al-Mussaib Technical College, in order to study the effect of bio-fertilization and salinity of irrigation water and the effect of their interaction on some chemical traits for clay loam soil and wheat growth, where a Completely Randomized Design (CRD) was used, with three replicates, and the treatments of the experiment were four qualities of saline irrigation water (river water 4, 6 and 8) and the number of experimental units was 24 experimental units. The results of the study showed the following:1-Irrigation with saline water at electrical conductivity (8 dS.m-1) (W3) led to a significant decrease in the height of plants (84.9 cm) and the dry weight of the total vegetative (33.47 g.pot-1) compared to the control treatment irrigated with river water (W0) at electrical conductivity (1.3 dS.m-1) which their averages amounted to (102.53 cm and 42.33 g.pot-1), respectively.2-The addition of bio-fertilizer led to a significant increase in the height of plants, the dry weight of the total vegetative, the number of spikes, the number of grains per spike and the weight of 1000 grains for wheat, which their averages amounted to (94.05 cm and 39.14 g.pot-1, 19.82, 39.50 and 37.24 g), respectively, compared to the control treatment (without the addition of bio-fertilizer), which their averages amounted to (89.29 cm, 34.78 g.pot-1, 17.78, 37.37, and 34.22), respectively.
