Based on the analysis of the above data, the following can be noted.
According to the results of experiments, the maximum branching
60x20-1 planting system 0-3-1 luck in feeding cotton with 200 kg / ha of
nitrogen, 150 kg / ha of phosphorus in the order of irrigation, 1-3-1 in
the irrigation order, similar data were obtained in other cotton varieties.
In the variant with a phosphorus content of 300 kg/ha and 180 kg/
ha, the plant was placed in a 60x20-1 system, and when cultivated in a
1-3-1 irrigation regime, the highest branching success was observed in
the cotton variety. This variety is relatively large, but has the same
number of branches, and the rest of the varieties are very close to each
other. Relatively low branching occurred when irrigated 0-3-1.
Minimum branching of cotton in the experimental fields When
cotton is fertilized with 300 kg / ha nitrogen and 180 kg / ha phosphorus
and irrigated in a 0-3-1 system, relatively more branching is successful.
We observed when the cotton was placed in a 60x15-1 system, the bran-
ching was further reduced.
