The data regarding average crop growth rate (ACGR) given in Table 2 reflected that
sowing techniques affected ACGR significantly in 2005-06, but effect was not significant
during 2006-07. The data revealed that trench sown sugarcane exhibited significantly
more ACGR (7.32 and 7.90 g m-2 day-1) than flat sown crop, which showed 7.21 and 7.68
g m-2 day-1 in 2005-06 and 2006-07, respectively. Weed-crop competition period
significantly reduced the ACGR during both the years of study. Weed competition free
crop (zero competition) by giving 8.12 and 8.85 g m-2 day-1 ACGR in both the years
proved significantly better than crop facing weed competition up to any duration till
harvest (weedy check). Reduction in ACGR was recorded with increasing the weed crop
competition during both the years of study.
