|Abstract:||A field experiment was conducted on "Yield and quality of sugarcane varieties as influenced by planting techniques on saline sodic soils" during preseasonal season of 2003-05 at Post Graduate Institute Farm, Department of Agril. Chemistry and Soil Science. The experiment was laid out in Factorial Randomised Block Design consisting of three main treatments and two sub treatments in four replications. The soil was calcareous, alkaline in reaction, low in nitrogen, phosphorus and high in potassium. The soil was having pH 8.7 and EC 0.59 dSnr1. The soil was grouped under inceptisol order. It belongs to Sawargaon (Pather) soil series which is a member of fine montmorillonitic, hyperthermic family of Sugarcane variety CO 86032 grown under saline sodic soil recorded higher cane yield (54.73 MT ha-1) which was at par with COM 9516 (52.00 MT ha-1). Set planting technique had recorded higher cane yield (51.35 MT ha-1) than polybag techniques (44.88 MT ha-1) in saline sodic soil. The juice quality of preseasonal sugarcane was significantly influenced by planting techniques irrespective of varieties. Brix and sucrose per cent were significantly higher in set planting (21.83 and 19.66 % sucrose) than polybag planting technique (19.52 and 18.42). Sugarcane genotype COM-9516 had higher proline content (573.99 JJ, mol g-1) than CO-86032 and CO-8014 (517.67 and 485.37 JJ mol g-1). Uptake of nitrogen and potassium was significantly influenced by sugarcane varieties. Set planting improved the total potassium uptake than polybag technique. Micronutrient uptake did not show consistent relationship between sugarcane varieties, planting techniques and their interactions in saline sodic soil. The results indicated that set planting technique of CO- 86032 variety had resulted in higher cane and commercial cane sugar yield over polybag technique with CO-8014 varietal on saline sodic soil.|
