This experiment
was laid out on 31st August 1995. In this trial, three levels of seed rate viz. 56,250
(So) (25% less than the recommended) 75,000 (S1) (recommended) and 1,12,500 (S2)
(50% more than the recommended), eye buds per ha and three levels of Nitrogen viz. 187.5
(No) (25% less than the recommended) 250 (N1) (recommended) and 375 (N2) Kg N/ha (50% more
than recommended) were imposed for normal furrow planting as well as paired row
planting method. In between laid out in randomised block design with three replications.
a) Yield and
yield attributres
The observations
on germination percentage, cane formed shoots (lakh/ha), plant height (cm), number
of internodes, number of millable canes ('ooo/ha), cane yield (MT/ha) C.C.S. Yield (MT/ha)
etc. are given in Table 1. Quality parameters are given in Table 2.
None of the juice
quality parameters were influenced either by methods of planting or seed rate or nitrogen
levels. Similarly fibre and moisture% also did not significantly differ due to any of the
treatments. All the interaction effects of all parameters were found non-significant.
Soybean which was sown in between paired rows of sugarcane failed due to severe incidence
of rust. It was sown in month of August-95 (late sowing).
Based on the
observations it is concluded that paired row planting produced same cane and CCS yield
compared to conventional furrow method of planting without leaving any deterimental effect
on any of the parameters studied. Therefore by adopting this method, weed control, becomes
cost and additional yield of intercrop could also be obtained. The optimum seed rate
for CoC 92061 is found to be @ 75,000 eye buds/ha for obtaining higher cane and CCS yields
and similarly varied levels of nitrogen increased sugarcane yield without having
significant ill effect on juice quality parameters. The suitable dose of nitrogen for CoC
92061 is found to be 250 Kg N/ha, (although 375 Kg/ha produced significantly higher CCS
yield) because application of N @ 250 and 375 Kg/ha produced non significant results with
respect to cane yields.
