Standardization techniques for soil mixture ratio and sowing depth in medicinal plants of Thar desert, India

The growth characteristics of three important medicinal plants of Thar desert, viz. Asparagus racemosus, Eclipta alba and Solanum surattense have been studied under different sowing depths and soil mixture ratios. Sowing depth of 1.0 cm and 1:1:1 soil mixture ratio [sand: clay: FYM] shows highest tuber yield in A. racemosus. However, sowing depth of 0.5 cm was suitable for both E. alba and S. surattense. The growth parameters were maximum in soil mixtures of 1:1:1 and 2:2:1 for E. alba and S. surattense, respectively
