Abstract

A field experiment was conducted at Department of Horticulture, College of Agriculture, Indore, during the rainy (kharif) season of 2009–10. Maximum plant height was attained in the treatment of 30 cm × 30 cm + 100% PSB (T1), followed by 30 cm × 30 cm + 100% Azotobactor + pinching (T4) and 40 cm × 40 cm + 125% Azotobactor + pinching (T8). Observations recorded on number of branches/plant showed at par results with each other among treatments except T1 (30 cm × 30 cm + 100% PSB), but highest number of branches in 40 cm × 40 cm + 125% PSB + pinching (T7) and T8-40 cm × 40 cm + 125% Azotobactor + pinching (T8). It was also recorded that differences among the treatments in respect of number of leaves/plant were at par except T1 and T5. However, it was higher in of treatment 30 cm × 30 cm + 100% Azotobactor (T2) and 40 cm × 40 cm + 125% PSB + pinching (T7), followed by 30 × 30 cm + 100% Azotobactor + pinching (T4), 40 cm × 40 cm + 125% Azotobactor + pinching (T7) and 30 cm × 30 cm + 100% PSB (T1). The higher leaf area/plant associated with treatment of 30 cm × 30 cm + 100% Azotobactor + pinching (T4) followed by 30 cm × 30 cm + 100% PSB + pinching (T3), T1-30 cm × 30 cm + 100% PSB (T1) and 40 cm × 40 cm + 125% PSB (T5), but result were at par among each other except treatment T6, T7 and T10. Similarly stem diameter also showed significant differences among the treatments and ranged between 2.11 and 2.55 cm. The significantly width and stem diameter were attained by the treatment 30 cm × 30 cm + 100% Azotobactor + pinching (T4), showing significant superiority over rest of the treatments except T7, T8 and T3, which were at par. The maximum yield was recorded with T4-30 cm × 30 cm + 100% Azotobactor + pinching (32928 kg/ha), followed by T3-30 cm × 30 cm + 100% PSB + pinching (32207 kg/ha) and T5-40 cm × 40 cm + 125% PSB (32161 kg/ha) and T2-30 cm × 30 cm + 100% Azotobactor (31707 kg/ha).
