Crop Regulation of Guava by Bending of Shoots:



This practice is very much dependent on training
of guava branches. On the basis of calculation of
expected flowering, the branches of guava plants
are bent down about 45-60 days before the
expected date of flowering and to produce fruits in
the off season.
First time bending of branches of guava plant
should be employed at the age of 2nd year of plant.
Before bending, the leaves, small shoots, flowers &
fruits from branch are removed or cut off,
keeping 10-12 inch of terminal twig intact.

During summer (April – June), the new shootlets
emerged within 8 to 10 days of bending
During autumn (Sept. – Nov.), the new shootlets
took 20-25 days to emerge
Bent branches should be untied when the new
shootlets is about 1 cm in length
Flowering occurs in the new shootlets at 4-5 pair
of leaf stage, after 45-50 days of summer bending
& 60-65 days of autumn bending
Manures & fertilizers should be applied 15 days
before bending of branches & again at pea stage
of fruit growth followed by irrigation.

Net Income (Rs./Bigha)
For guava cv. Allahabad
Safeda :
Total no. of fruits=258/plant
Yield=258x187g=48.25kg/plant
48.25x50 = 2400 kg/Bigha
Gross income =2400x10 =Rs.24000
(@ Rs.10/kg of fruit)
Net income (Rs./Bigha)
= (24000-7800)=Rs. 16200 /Bigha
For guava cv. Khaja :

Total no. of fruits=225/plant
Yield=225x289g=65.02 kg/plant
65.02x50 = 3250 kg/Bigha
Gross income =3250x10 =Rs.32500
(@ Rs.10/kg of fruit)
Net income (Rs./Bigha)
= (32500-7800)=Rs. 24700 /Bigha
