In the experiment following treatments viz. control; Soil + Sand (1:1); Soil + Vermiculite (1:1); Soil + Cocopeat (1:1); Soil + Perlite (1:1); Soil + Vermiculite + Perlite (1:1:1); Soil + Vermiculite + Cocopeat (1:1:1); Vermiculite + Perlite + Cocopeat (1:1:1); Soil + Sand + Vermiculite + Perlite (1:1:1:1); Soil + Sand + Vermiculite + Cocopeat (1:1:1:1) and Soil + Sand + Vermiculite + Cocopeat + Perlite (1:1:1:1:1). Among different treatments combination used the medium Soil + Sand + Vermiculite + Cocopeat + Perlite (1:1:1:1:1) with cow urine found significantly superior over other treatments and control with respect to that minimum days required for first germination (6.17 days) and for 50 per cent germination (9.00 days), span of germination (19.17) and maximum germination percentage (90.24%). It has also given better height of seedling (15.48 cm), number of leaves per seedling (9.83), stem girth (7.75 mm), leaf area (51.85 cm2), vigour index-I (1550.27 cm), vigour index-II (59.55 g), fresh weight of seedling (2.86 g), and dry weight of seedling (0.42 g) at 75 days after sowing. The maximum length of longest tap root (14.20 cm), diameter of tap root (4.12 mm), number of secondary roots (17.00) and root/shoot ratio (0.869) were also found significantly superior in the same treatment as compared to rest of the treatments. Further, it was also found superior with relation to maximum nitrogen (1.87%), phosphorus (1.14%), potassium (2.26%) and chlorophyll (2.49 mg/100g).EnglishThesis
