摘要

An experiment with different organic and inorganic nutrients'-was conducted at the Bidhan Chandra Krishi Viswavidyalaya during the year 2001 to 2005. The experiment was laid out in randomized block design with three replications. The results of applicaton of different organic and inorganic nutrients viz., (i) 50% of the recommended dose of NPK (T-1) (ii) 100% of the recommended dose of NPK (T-2) (iii) 50% of the recommended dose of NPK+Azospirillum inoculation (T-3), (iv) 50% of the recommended dose of NPK+VAM inoculation (T-4), (v) 50% of the recommended dose of NPK+Azospirillum+VAM inoculation (T-5), (vi) 100% of the recommended dose of NPK+Azopirillum inoculation (T-6), (vii) 100% of the recommended dose of NPK+VAM inoculation (T-7), (viii) 100% of the recommended dose of NPK+Azospirillum+VAM inoculation (T-8), (ix) Control (T-9) of flowering behaviour of mango cv. Himsagar (25 years old trees). The highest shoot growth was recorded in the plants receiving 100% recommended doses of fertilizers alongwith Azospirillum and VAM inoculation, whereas maximum flowering (63.60%) and fruiting (71.33%) were observed in the plants supplied with 50% recommended doses of nutrients combined with Azospirillum and VAM inoculation. The nitrogen, phosphor-us, potassium, phenol, starch, total and reducing sugar, non-reducing sugar content, C/N ratio of shoot and leaf were determined and the number of microbial propagules in different months and of different treatments was also counted. The results indicate that application of Azospirillum and VAM alongwith 50% recommended dose of fertilizers significantly influenced the physiological and biochemical behaviour in relation to flowering in mango cv. Himsagar. It was suggested that higher intensity of nitrogen fixing microbial colony improved the nutritional status of plants, which enhanced the growth response, flowering and related biochemical parameters.
