Dear Sandeep sir, Any crop requires full attention if it is planted at high/ultra high density. For high density plantation, G9 banana, reciprocates well. Proper timely care should be taken for diseases, insects etc and good ,caliculated fertigation schedule to be maintained.
When i attended the symposium of world banana (paired row system high density) , it is learnt that the following system do well.
4 ft x 4ft x6 ft x4 ft x 4 ft x 6ft x 4ft x 4 ft…of the rows , north to south and in the rows at 4 ft interval from east to west. It can acoomodate around 2100 plants.
Immediately,in peddipalem village of visakhapatnam dist of AP, i did plantation of G9 banana in 2 acres and planted 4200 plants. Good, medium results were witnessed. On average each bunch weighed around 28 kgs and i got a yield of 59 tonnes per acre (118 tonnes for 2 acres).
I have inspected several farms planted, (1) 3.5 ft x 3.5 ft x 6 ft x 3.5 ft x 3.5 ft x 6 ft…, and at 3.5 ft in the rows…,(2) at 6 ft distance row to row and plant to plant and planting 2 plants at each place of one plant, which can accomodate 2400 plants per acre.
I suggest you to plant @ 2000 to 2500 plants per acre as per your convinience in diffarent spacings , all in half acre ( 1000 to 1250 plants per half acre ), and study and come to a conclusion that which syatem suits you well.
Already one farmer of karnataka got 69 tonnes per acre , so many times and got a doctorate also.
I suggest you to follow feeding fully organic or atleast 60 to 75 % organic mannures.
Hope you will be a role model in future in banana farming. g.p.rao, farmer
