Abstract
In order to investigate the effects of various soil amendments, including municipal waste compost its biochar and bentonite in the presence of pollutant nickel, on morphological characteristics, yield, and nutrient absorption of triticale seeds, a factorial experiment was conducted based on a completely randomized design with 3 replicates in the research greenhouse of the College of Agriculture and Natural Resources of Darab, Shiraz University. Experimental factors included: Nickel at three levels: control (no nickel application), 150 mg nickel/kg soil, and 300 mg nickel/kg soil supplied from a nickel chloride source, and soil amendments at seven levels: control, municipal waste compost, biochar, bentonite, bentonite and biochar, bentonite and municipal waste compost, biochar, and municipal waste compost, each at a level of 2% by weight. The results showed that the effect of different levels of soil amendments on morphological traits was significant. The highest plant height (80.29 cm) was related to the use of municipal waste compost. The highest seed yield of triticale (1.86 g/plant) was obtained with the application of municipal waste compost. All seed nutrients were affected by the interaction of nickel and soil amendments at the 1% probability level. It was interesting that, the highest seed phosphorus content (0.29%) was obtained with the application of 300 mg of nickel combined with the application of bentonite and biochar. The highest seed zinc concentration with an average of 49.8 mg/kg and seed manganese with an average of 38.3 mg/kg were obtained in the absence of nickel and the addition of biochar.
