He said that boll
picked by the machine are exposed before sunlight to kill pink boll
-worm and larvae inside them.
Every Mississippi child knew a cotton boll
when he or she saw one.
The previous studies reports the DCB population decline from 24 to 4 per boll
after first spray and 1.
The spatial and temporal distribution of reproductive structures [cotton squares of large (68mm diameter), medium (3-6mm diameter), and small bolls
size (5-8mm diameter)] fallen on the soil damaged by boll
weevil between cotton rows were determined in a randomized block design with a factorial arrangement of 4x3, represented by soil surface tracks located at 1-11cm, 12-22cm, 23-33cm, and 34-44cm away from planting row on cotton plants at 70, 85, and 100 days of age.

Plant height, number of bolls

The stripper-type harvester combed the plant with teeth or drew it between stationary slots or teeth, while the picker- or spindle-type machine was designed to pick the open cotton from the bolls
using spindles, fingers, or prongs, without injuring the plant's foliage and unopened bolls
General combining ability mean squares for all the characters were significant at 5% level of probability in case of plant height and lint index, and were significant at 1% level for sympodial branches plant-1, number of bolls
weight, seed index and seed cotton yield plant-1.
After this the attack of spotted boll
worm will be started which also effect the crop growth.
The mean performance of parents and their hybrids have been summarized in Table 1, which indicates that among the parents, FH-113 formed maximum bolls
/plant, produced highest number of sympodial branches/plant and gave maximum seed cotton yield/ plant, highest seed index and ginned maximum lint%; the dwarfed plant with heavier bolls
were recorded by the parent IR-1524.
are aspirated by bugs, and even if they manage to open, they have lighter seeds and therefore, making higher seed-lint ratio.
Consequently, this feeding by puncturing the flower buds or the young cotton bolls
usually causes reduction in size; or the fruiting body may abort and drop to the ground.
