CROP REGULATION OF GUAVA BY BENDING OF SHOOTS Prof. B. Ghosh Department of Fruits and Orchard Management Faculty of Horticulture Bidhan Chandra Krishi Viswavidyalaya Mohanpur, Nadia, W.B. 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. Crop Regulation of Guava by Bending of Shoots- contd……. 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.
