Description 172-176
In agricultural field experimentation, the result of an experiment conducted at particular place or in a particular
year is not of practical use unless the experiment is conducted with same set of treatments over two or more
than two years/locations. The combined results of the experiment after pooling over number of years/locations
will be more broad based and more stable and help research workers in formulating their future experimental
programmers and the extension workers in disseminating information for practical farming. The object of this study was to find the optimum time of harvesting and dose of potash for sugarcane crop in various states
of the country by using suitable response surface model. In most of the cases optimum times of harvesting
and doses of potash were calculated by using Quadratic Response Surface model for sugarcane crop. In Andhra
Pradesh optimum level of harvesting time was observed 12.96 months after planting at optimum level of 119.7
kg/ha of K₂O and its yield was 1106.87 qlha. In Bihar, optimum level of harvesting time was observed 11.04
months after planting at optimum level of 135.9 kg/ha of K₂O and yield was 796.00 qlha. In Maharashtra,
optimum level of harvesting time was observed 13.49 months after planting at optimum level of 175.89 kg/
ha of K₂O and yield was 1407.90 q/ha. In Kamataka, optimum level of harvesting time was observed 16
months after planting at optimum level of 151.9 kg/ha of K₂O and yield was 1666.83 q/ha. In Uttar Pradesh,
optimum level of harvesting time was observed 14 months after planting at optimum level of 177.5 kg/ha
of K₂O and yield was 692.45 q/ha. In most of the states early harvesting and late harvesting of sugarcane
were not beneficial for maximum yield.
