we are having good quality & high yield G9 banana saplings promoted by tissue culture.I recently harvested banana fruit bunch in my nursery garden without any specific fertilisers and care .only giving water to banana plants regularly.Some body told after visit my banana tree and told their opinion that your tree will gives only minimum yield i.e 35 kgs.Because our area very hot and tropical climate i.e minimum 20 celious and maximum 39.4 celious (In vellore 40.3 c in peak summer).Recently i have harvested the banana fruit bunch last week now also 104 f temparature.By the grace of god the weight of the G9 fruit bunch was 52 kgs.So all tissue culture promoting companies are major vital role .The setting of mother culture and using bio harmones ,bio fugicide & fertilisers .And the secientist of the tiisue culture lab is very very very important factor.the secientist is just like skilled artist like cinema director.the director is good the move will succeed.
