Abstract:
An experiment was conducted to observe the effect of various rooting media on the growth of stools. During the investigation programme, ten hilling materials were applied viz., Vermiculite (T1), Saw dust(T2), FYM (T3) ,Vermicompost (T4), Vermiculite + Saw dust + Pseudomonas (T5), Vermicultite + Saw dust +Azotobacter (T6), FYM + Vermicompost + Pseudomonas (T7), FYM + Vermicompost + Azotobacter (T8), Pseudomonas + Azotobacter+ Soil (T9), Control(T10) (only soil was used as a hilling material). The rootstocks used during the research programme consist of M-9 T337 (S1), M-27(S2), MM-106(S3), P-22(S4), MM-111(S5). The experimental results showed that maximum shoot incremental growth (67.90 cm), shoot length (120.46 cm) and leaf area (32.00 cm2) were recorded under FYM + Vermicompost + Azotobacter treatment. Maximum mean soil hydrothermal condition Viz., temperature (26.130C) was recorded under saw dust treatment. Maximum mean soil moisture content (23.44%) was recorded in under vermiculite which was significantly, higher as compared to all other hilling media however root fresh weight (8.05) and root dry weight (5.91g), were recorded with saw dust (T2). The minimum shoot incremental growth (38.83 cm), shoot length (61.62 cm), leaf area (26.90cm2), root fresh weight (4.43 g), root dry weight (2.43 g) and mean soil hydrothermal conditions viz., soil temperature and soil moisture were observed under control (only soil was used a hilling media). Among the various propagation techniques it was observed that propagation technique P2 (trench layering) had a significant effect over P1 (mound layering) with regard to average shoot length, shoot incremental growth and leaf area.
