Abstract
A field experiment was conducted to study the efifect of planting methods
and intercrops on growth and yield of sugarcane in medium deep black soil at Kamataka
Institute of Applied Agricultural Research, Sameerwadi during 1997-98. The experiment
consisted of two planting methods and seven intercrops compared with sole sugarcane.
The experiment was laidout in split-plot design with planting methods at m^n plots and
intercrops in the sub plots. The treatments were replicated four times.
The data revealed that planting methods did not influence the cane yield
and sugar yield. However, paired row method of planting recorded higher cane yield
(102.57 t/ha) and sugar yield (11.29 t/ha) than normal method of planting (101.15 t/ha and
11.23 t/ha, respectively). Similar response was observed with LAI, dry matter produced
per plant throughout the crop growth and yield components at harvest.
Intercropping and incorporation of iti situ green manure like sunnhemp
recorded higher cane yield (111.09 t/ha) and sugar yield (12.49 tflia) compared to rest of
the treatments. Intercropping of sugarcane with maize recorded significantly the lowest
yield (70.82 t/ha) and sugar yeild (7.60 t/ha). The yield attributes like intemodal length
and cane weight per plant recoreded numerically higher values in sugarcane + sunnhemp
intercropping system as compared to other treatments. The dry matter production, LAI,
plant height, number of intemodes and number of leaves were highest in sole sugarcane at
90 150 and at 210 DAP compared to other treatments and later on differences were
smoothened out (i.e., 270, 300 DAP and at harvest).
Intercropping of sugarcane with soybean gave higher gross (Rs. 99,248/ha)
and net income (Rs. 68,336/ha) while, sugarcane intercropped with maize recorded the
lowest gross income (Rs. 68,142/ha) and net income (Rs. 36,374/ha). Benefitxosi ratio
was the highest when sugarcane was intercropped with soybean (3.21) while, cane
intercropped with maize recorded lower benefif.cost ratio (2.15).
Therefore, for getting higher net income, sugarcane may be intercropped
with soybean under paired row method of planting.
