Maize is the third most important cereal crop due to its importance in food, feed, fuel, specially corn, starch etc and acquires an important place in the food grain basket of our country. There is a need of better production technology to reach higher productivity to meet the projected demand in India. LCO (lipo-chitooligosaccharide) Promoter Technology present in Torque is a unique molecule enhances a plant’s nutritional capabilities that ultimately leads to higher yields and better returns at the end of the season when present at the time of planting independently of variety, soil and environmental conditions. So, a field experiment was conducted at Central Research Farm, Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal, India during Rabi seasons of 2012-14 to study the effect of bio-product Torque (LCO Promoter Technology) as seed treatment on growth and productivity of corn. The experiment was laid out in randomized block design with seven treatments combining Torque RTA @ 4 ml/2 kg seed, 8 ml/2 kg seed and 12 ml/2 kg seed and time of treatment @15 days before sowing and at the time of sowing, replicated thrice. Results revealed that treated plot performed better than untreated plot. Seed treatment before 15 days of sowing with high dose performed better than those sown immediately after treatment. The yield parameters like cob length, number of cobs plot-1 and cob yield were reflected better with Torque RTA @ 12 ml/2 kg seed treated at 15 days before sowing which ultimately resulted the highest grain yield of 6.83 t ha-1.
