The results of the study are in line with the factory average over the years in wide row, the details are given in Table 1. Under wider row spacing, the technologies adopted in the area include drip irrigation, paired row planting, use of intercultural implements such as disc harrow, mini tractor and de-ridger cum stubble shaver. Trash mulching, growing green manures and intercropping with leguminous crops are also being done easily in the space between wider rows. Performance of Wider Row Spacing in Frontline Demonstrations. To popularize wide row spacing among farmers, frontline demonstrations were conducted by the first author in farmers’ fields in Coimbatore, Erode and Tirupur districts. Frontline demonstrations are first line demonstrations conducted by the research scientists to demonstrate promising technologies in the farmers’ fields under different agro-climatic regions and farming situations. These demonstrations are conducted under the macro management mode sponsored by the Ministry of Agriculture, Government of India Table 2. Invariably, in all the demonstrations, wide row spacing/ paired row spacing of 120 9 60 cm gave higher cane yield than the farmers’ practice of 90 cm spacing. The range of difference in cane yield was 5.70–41.59 t/ha. Since the demonstrations were conducted in farmer’s fields at varied locations such a vast range in yield difference is justified. There are reports from around the world indicating higher cane and sugar yields with wider row spacing (Richard et al. 1991). Irvine et al. (1980) considered that wider rows or wider distances between plants produced higher stalk numbers and higher cane yields in sub-tropical areas. Similarly, wider row plantings in tropical areas have been found to produce higher cane yields, facilitate mechanization of field operations and reduce production costs (Sundara 2003). Coleti et al. (1987) indicated greater yields with a wider spacing of 110 cm when compared to narrower spacing. Under Vapi in South Gujarat conditions, it has been reported that yields of 341 t/ha were achieved by adopting wide row spacing (MangalRai 2002). Wider row spacing of 150 cm gave significantly higher cane yields (156.6 t/ha) than the conventional row spacing (95.3 t/ha). Patel et al. (2006) evaluated the effect of different row spacing in Western Maharashtra and recommended that sugarcane should be planted at 75/150 cm paired rows or four rows planting at 90–180 cm for better yield. Scandaliaris et al. (1989) observed that growing sugarcane up to a 160 cm interrow spacing increased shoot and stalk population and raised the efficiency of solar energy utilization.
