Crop geometry under border strip irrigation at IW/CPE ratio 1.0 did not influence the sugarcane yield, yield components and cane quality (Table 2). However, highest cane yield (98.80 t/ha), tillers (13.53/sqm), internode length (17.40 cm). Commercial canesugar (8.68 t/ha), juice content (35.30%), Brix percentage (15.97) and juice purity (82.50%) were obtained at 75 cm row spacing. Row spacing of 90 cm recorded highest cane girth (2.57 cm cane diameter) and commercial cane sugar (8.88%). Higher yield and most of the yield components with 75 cm row spacing might be due to proper utilization of resources in harsh arid climate of Rajasthan. Crop geometry under drip irrigation system significantly influenced cane yield and highest yield of 130.64 t/ha was recorded with 75 cm row spacing followed by 126.13 t/ha at 90 cm row spacing. Higher yield in 75 and 90 cm row spacing was attributed to higher tillers/m², cane length and inter node length. Paired row plantings fetched lower yields where single drip line was kept between 2 paired rows of sugarcane.
