Title : Evaluation of promising varieties for Early, Mid and Late crushing Season -6 experiments (Pooled data)

Author : R.B. Khandagave and P.G. Satpute.

Year : 1996-97and 1997-98.

Six experiments conducted during 1995-96 and 1996-97 season starting from September to February. Each experiment was laidout in completely Randomised Block Design with three replications and seven varieties with four harvesting dates combinations. The promising varieties tested in the experiments were CoC 671, CoC 92061, Co 85246, Co 87044. Co 86032, CoM 88121 and Co 8014 with 10th, 12th, 14th and 16th month of harvests. The mean values obtained from these two years of experiments are discussed below.

1. Experiment planted in the month of September (Table 7)

Among the varieties CoC 92061 (95.76) and CoC 671 (91.42) ranked first and second in terms of producing cane yield similarly CCS yield was 12.34 and 11.49 t/ha respectively. Other varieties which noticed as promising are Co 86032, Co 87044 and CoM 88121 in producing both cane and CCS yield. Increased age of harvest irrespective of varieties increased cane as well as CCS yield however more pronouncedeffect was noticed from 10th to 14th month of harvest and their after increase was slower.

2. Experiment planted in the month of October (Table 8):

Among seven varieties, CoC 92061 stood first in terms of cane yield (89.85) followed by CoC 671 (87.04), Co 87044 (84.38), Co 86032 (82.43) and CoM 88121 (80.77). 16th month of harvest produced significantly higher cane yield during both the years compared to 10th, 12th and 14th month of crop age. Similarly CCS yield was found maximum (12.37 t/ha) in CoC 92061 and followed by CoC 671 (11.59 t/ha) next being Co 86032 (10.54 t/ha), Co 85246 (10.49) and Co 87044 (10.44 t/ha). Significantly higher CCS yield was observed in both the years when harvesting was done at 16th month of crop age compared to 10th, 12th and 14th month of crop age. The mean value was maximum (13.98 t/ha) 16th month and 7.16 t/ha at 10th month of crop age.

3. Experiment planted in the month of November (Table 9):

Co 86032 (93.17 t/ha) and CoC 671 (91.65 t/ha) stood first and second in producing cane yield (mean values). The next varieties performed in descending order were CoM 88121 (88.68 t/ha), Co 87044 (87.66 t/ha), Co 85246 (80.45) and Co 8014 (79. 80 t/ha). Age of harvest also produced significantly higher cane yield from 10th month of harvest at biomonthly interval during both years. The maximum cane yield was  102.74 t/ha at 16th month and minimum at 10th month of harvest (71.48 t/ha). CCS yield was maximum in Co 86032 (12.90 t/ha) followed by CoC 671 (12.82 t/ha), CoC 92061 (12.49 t/ha) and CoM 88121 (12.0 t/ha). Similarly significantly higher CCS yield observed in both years and the maximum CCS yield was noticed at 16th month  (15.43 t/ha) and minimum being in 10th month (6.81 t/ha).

4. Experiment planted in the month of December (Table 10):

CoC 671 (87.42 t/ha) and Co 86032 (86.68 t/ha) produced higher cane yield followed by CoC 92061 (85.43) and CoM 88121 (85.21 t/ha). Significantly higher cane yield was observed in both the years due to age of harvest. In this case maximum cane yield was 96.84 t/ha and minimum at 10th month (68.33 t/ha). However CCS yield was higher in CoC 92061 (12.40 t/ha) and followed by CoC 671 (12.18 t/ha). Comparatively higher CCS yield was also obtained in Co 86032 (11.87 t/ha) and Co 87044 (11.44 t/ha) CoM 88121 (11.34 t/ha). In both the year significantly higher CCS yield was obtained at 14th month of harvest even compared to 16th month of harvest. Maximum CCS yield of 13.53 t/ha was observed at 14th month of harvest and 7.72 t/ha which was minimum at 10th month of crop age.

5. Experiment planted in the month of January (Table 11):

CoC 671 (98.14 t/ha) , Co 92061 (96.43 t/ha) were found better cane yield producers then followed Co 86032 (95.04 t/ha) and CoM 88121 (95.01). 16th month of harvest produced  aximum yield of 107.15 t/ha and minimum cane yield of 77.96 t/ha at 10th month of crop age. Significantly higher CCS yield was observed at 16th month of crop age however was on par with 14th month of crop age in both the years. Maximum CCS yield was observed at 16th month (14.56 t/ha) and at 10th month of crop age it was minimum (10.56 t/ha).

6. Experiment planted in the month of February (Table 12):

Maximum cane yield was observed in Co 86032 (100.13 t/ha) and then followed CoM 88121 (94.07), CoC 92061 (93.76), CoC 671 (93.44), Co 8014 (92.49) and Co 85246 (90.15) significantly higher cane yield was observed at 16th month crop age however it was on par with 14th month of crop age during seaons. Co 86032 recorded maximum CCS yield (14.22) followed by Co 85246, CoC 92061 (13.76) and CoC 671 (13.49 t/ha). 14th month of crop age recorded maximum CCS yield (14.65) then closely followed by 12th month (14.01) compared to 10th (11.33) and 16th month (13.29) of harvest.
