Abstract
An experiment on "Effect of biofertilizers and chemical nitrogenous fertilizer on growth and flower yield of chrysanthemum (Chrysanthemum morofolium Ramat)" was conducted at College Nursery of B.A. College of Agriculture, Anand Agricultural University, Anand during the winter season of 2004 - 05. The treatments comprising two biofertilizers (Azospirillum and Azotobacter) and three nitrogen doses (200, 170, 150 kg N/ha) including control (recommended dose) were tried in Randomized Block Design with three replications. The results revealed that 175 kg N/ha + Azotobacter + Azospirillum (T9) produced significantly maximum plant height at first flower picking (70.93 cm), number of branches per plant (6.29) and plant spread (24.20 cm2) followed by 200 kg N/ha + Azotobacter + Azospirillum (T8). The plants under the treatment T9 (175 kg N/ha + Azotobacter + Azospirillum) required significantly minimum days for appearance of first flower bud (85.47 days), it was followed by treatment T8. Treatment T9 produced maximum number of flowers per plant (44.51) and also recorded maximum flower diameter (7.18 cm) as well as weight of individual flower (3.11 g) followed by treatment T8. Significantly the highest flower yield per plant (110.33 g) as well as per hectare (11.76 t) was recorded in treatment T9 and followed by treatment T8, (102.33 g) and (10.841) flower yield per plant and hectare, respectively. The treatment T7 (150 kg N/ha Azospirillum) produced flowers with maximum vase life (15.25 days), keeping life with pedicel (12.0 days) and keeping life without pedicel (7.72 days). The treatment T9 (175 kg N/ha Azotobacter + Azospirillum) recorded the highest net realization (75153 Rs / ha) as well as highest cost benefit ratio (1:2.77) and saved 25 percent nitrogen.
