Abstract:

The present study was conducted to observe the activity of thrips on garlic crop using variety Yamuna Safed-3 at Regional Research Station, NHRDF, Salaru, Karnal (Haryana) during three consecutive years i.e. Rabi, 2011-12, 2012-13 and 2013-14 seasons, which was based on a Randomized Block Design with six planting dates, i.e. October 1st (D1), October 15th (D2), November 1st (D3), November 15th (D4), December 1st (D5) and December 15th (D6). The bed size was kept as 3.6m x 1.8m with 5 replications. The data on thrips population (nymphs/plant) were counted on 10 plants selected randomly in each replication at seven days interval. The result revealed that significantly lowest mean thrips population (4.71 nymphs/plant) were recorded in 1st October planted crop, which was found at par with 15th October planted crop (6.71 nymphs/plant) and 1st November planted crop (7.74 nymphs/plant). Significantly highest mean thrips population (13.73 nymphs/plant) was recorded in 15th December planted crop due to increase in temperature from 26.56 to 35.65ºC during observational period. The significantly highest yield (113.39 q/ha) was recorded in 1st October planted crop, which was found at par with 15th October planted crop (111.21 q/ha) and 1st November planted crop (105.92 q/ha).
