The influence of irrigation with ABSAR supplement on the growth of Panicum eruciferum

Limitations of water resources in the country and allocating a large share of water to agriculture section and natural resources is considered as an essential and vital matter to increase the efficiency of consumption and saving water. In this context, using modern technology with the use of some additive materials like supplements to the soil can play a major role in reducing drought stress in arid and semi-arid areas. In this study, the effect of ABSAR supplement was investigated on physiological features of “Panicum eruciferum” species. Greenhouses were used to increase the accuracy of the culture medium. Treatments used in this study were included normal irrigation, ABSAR supplement at two concentrations (1/10000, 1/6000) and three times of irrigation (one-day, three- day and six-day). The results showed that ABSAR supplement at a concentration of 1/10000 increased root length, stem length, root and stem dry weight as well as root specific weight. Using ABSAR also increased the irrigation intervals. However, the supplement at a concentration of “1/6000” caused a significant difference in increasing the ratio of root to stem length. Irrigation with ABSAR supplement at a concentration of “1/10000” and “1/6000” had no significant effect on the ratio of root-to-shoot dry weight. The ratio of root- to-shoot length and the ratio of root-to-shoot dry weight increased with increasing of stress from daily irrigation to every six-day irrigation.
