Application of biochar and superabsorbent on the morphological characteristics of forage maize (Zea mays L.) in Varamin region.

In order to investigate the application of biochar and superabsorbent on some morphological characteristics of the forage maize plant (Zea mays L) in Varamin region was performed in the field. The experiment was performed as split plots in a randomized complete block design with three replications. The first factor is superabsorbent in 100% bile concentrations (S0, S1, respectively), the second factor is biochar coal consumption with a ratio of 0, 5 and 10 tons per hectare (B0, B1 and B2, respectively). The title of the treatment was considered. The water cycle included seven, 10, 13 days and 10 and 13 (D0, D1 and D2, respectively) as the main plot. The superabsorbent factor had a significant effect on the saturation loss percentage traits. Biochar factor had a significant effect on leaf fresh weight and leaf dry weight, total chlorophyll, relative water content, saturation loss percentage. The dual effects of irrigation and superabsorbent had a significant effect on leaf fresh weight, leaf dry weight, total fresh weight, total dry weight, chlorophyll a, chlorophyll b, total chlorophyll, saturation loss percentage. Factor of dual effects of irrigation and biochar significant effect on plant height, leaf fresh weight, leaf dry weight, total fresh weight, total dry weight, leaf area index, chlorophyll a, chlorophyll b, total chlorophyll, saturation loss percentage Had. The dual effects of superabsorbent and biochar had a significant effect on leaf fresh weight, leaf dry weight, total fresh weight, total dry weight, chlorophyll a, chlorophyll b, saturation loss percentage. Factor of triple effects of irrigation, superabsorbent and biochar A significant effect on plant height, fresh leaf weight, leaf dry weight, crack weight and total dry weight, leaf area index, chlorophyll a, total chlorophyll, relative water content And had a saturation loss percentage.
