Onion occupies an important place in daily diet and is semi-perishable in nature. The production of off-season onion in Kharif season in North Indian plains can stabilize the market supply of fresh onion as well as its price in winter and spring seasons. Keeping this in view, the present investigation was carried out at the experimental farm of Krishi Vigyan Kendra, Bilaspur, Himachal Pradesh during 2013 and 2014. Two varieties namely, N-53 and Agrifound Dark Red (AFDR) were evaluated using sets and seedlings following randomized block design in four replications along with Farmer practice (FP). The marketable bulb yield of both the varieties raised through sets was significantly higher than those raised from seedlings during both the years. The higher bulb yield was the result of low mortality of seedlings and improved crop stand which resulted in higher economic returns. In another experiment on weed management practices, pre- emergence application of alachlor and pendimethalin @ 1.00 kg a.i. /ha, respectively along with hand weeding at 40 days after planting resulted in significantly higher bulb yield compared to their sole application. Hence, Kharif onion crop raised through sets of AFDR variety followed by N-53 is better than seedling raised crop under low hill conditions of Himachal Pradesh.Keywords

The efficacy of six insecticides namely chlorpyriphos 20 EC (5.0 ml/kg seed), imidacloprid 17.8 SL (5.0 ml/kg seed), clothianidin 50 WDG (3.5 g/kg seed), thiamethoxam 25 WG (3.5 g/kg seed), bifenthrin 10 EC (2.5 ml/kg seed) and chlorantraniliprole 18.5 SC (2.5 ml/kg seed) as seed treatment was tested against grubs of Melolontha indica Hope under laboratory conditions. Rajmash, Phaseolus vulgaris L. was used as test crop. The experiment was conducted in plastic trays filled with soil and farm yard manure (FYM) in 3:1 ratio. In each tray, ten third instar grubs of M. indica were released and 20 treated rajmash seeds were sown at a depth of about 5 centimeter. The results revealed that plants from chlorantraniliprole 18.5 SC (2.5 ml/kg seed) treated seeds registered least mortality (20.0 %), followed by chlorpyriphos 20 EC (5 ml/kg seed) (21.67 %) at 10 days after sowing (DAS). The grub mortality recorded in seeds treated with chlorantraniliprole 18.5 SC (2.5 ml/kg seed) and chlorpyriphos 20 EC (5 ml/kg seed) was 56.67 and 46.67 per cent, respectively at 20 DAS. Therefore, seed treatment with chlorantraniliprole 18.5 SC (2.5 ml/kg seed) could be another alternative in addition to chlorpyriphos 20 EC (5 ml/kg seed) for effective management of M. indica grubs infesting rajmash under field conditions in high hills of north western Himalaya.Keywords
