The effect of bio-fertilizer was studied in banana accessions intensively collected from ICAR Research Complex for NEH Region, Mizoram Centre, Kolasib, Mizoram during 2009-2010. To assess the efficacy of different bio-fertilizer viz., Azospirillium, Azotobacter and phosphorus solubilizing bacteria (PSB) either alone or in combination was applied 20g per plant with recommended dose of FYM. The six treatments were arranged in a Randomized Block Design in three replications and spaced at 2.5 × 2.5 m in order to study its effect on growth, yield and quality attributing traits. All the characters were significantly increased except number of suckers and number of leaves due to application of each of the two-bio fertilizers either separately or in combination. Moreover in combination ofAzotobacter + PSB 20g per plant showed that more effective than either combination or in separately of another bio-fertilizers. This might be due to because biological nitrogen fixation depends appreciably on the available form of phosphorus. So the combined inoculation of nitrogen fixers and PSB may benefit the plant better (by providing both nitrogen as well as phosphorus) than either alone.Keywords

The present investigation was carried out at the Horticulture Research Center, of the SardarVallabhbhai Patel University of Agriculture and Technology, Meerut during 2013- 2014.The maximum number of fruits (20.85) were recorded in the variety Chandler which was significantly superior to the rest of the varieties and followed by Gorella,Selva and Confictura.The maximum fruit yield per plant (385.57g) was recorded in the variety Chandler which was superior to the rest of the varieties and was followed by Selva, Confictura and Douglas. The minimum fruit yield per plant (177.79g) was noted in Gorella variety.The maximum fruit weight (18.41g) was recorded in the variety Chandler which was significantly superior to the rest and followed by Confictura, Selva and Douglas.Application of gibberellic acid (GA3) 100 ppm + vermicompost @ 100q/ha was found to be the best treatment in response to fruit weight among different varieties of strawberry and recorded 16.48g. The maximum fruit yield (171.36q/ha) was recorded in the variety Chandler which was significantly superior to the rest and was followed by Selva, Confictura and Douglas; however, Selva and Confictura were statistically at par to each other. Variety Chandler responded maximum effect on fruit yield per hectare i.e. 205.357q/ha with the spray of gibberellic acid (GA3) 100 ppm and application of vermicompost @ 100q/ha. The maximum total soluble soilds (10.68ºBrix) was recorded in the variety Douglas which was superior to the rest and was followed by Confictura, Selva and Gorella. The minimum TSS value (9.41ºBrix) was noted in Chandler variety. Douglas responded maximum effect on TSS value i.e. 11.50 ºBrix with the spray of gibberellic acid (GA3) 100 ppm and application of vermicompost @ 100q/ha as basal dose which was statistically significant to other treatments and followed by Confictura, Selva and Gorella. Viewing the above observations, Chandler, Confictura and selva were found promising for commercial cultivation, however, Gorella was found to be earliest among all.
