| Abstract:
It was seen from the data that both Cultar (87.2%) as well as Austar (85.4%) were slightly more effective in inducting flowering in mango trees than the untreated control trees (83.6%). More over both the products were effective in inducing earlier flowering by 20 to 30 days than the control. However, Cultar as well as Austar both were at par with each other in their effectiveness on induction of flowering and earliness of flowering. The induction of flowering in all the treatments including Control was much higher due to prolonged lower temperatures causing better induction of flowering. The use of Cultar and Austar was significantly better in getting more number of mango fruits per tree (65.25 and 70.52 fruits/tree, respectively) as compared to the control (44.73 fruits/tree). However there was no statistically significant difference in number of fruits harvested from trees treated with these two products. Therefore the conclusion from these results is that Cultar as well as Austar are equally effective in inducing flowering as well as fruiting in Kesar mango under Jamnagar conditions. These results have been confirmed by the large scale use of Austar on our Farm during 2004-05 flowering season also. Therefore one can use either Cultar or Austar for flowering and fruiting in mango. At present Austar is available in the market at prices 40% cheaper than Cultar and hence mango growers can save substantial amounts by using Paclobutrazol in other brands like Austar. | |
