Effect of nitrogen sources on thrips, Scirtothrips dorsalis Hood in chilli

Author(s): RG Samota and BL Jat
Abstract: Investigations on “Effect of nitrogen sources on thrips, Scirtothrips dorsalis Hood in chilli.” were conducted at Horticulture farm, S.K.N. College of Agriculture, Jobner during Zaid, 2014 and 2015. Among the different sources of nitrogen the treatments T4 (100% N through NC), T3 (75% N through NC + 25% through urea), T8 (100% N through VC) and T7 (75% N through VC + 25% through urea) resulted in the population of thrips (3.69 to 3.96 thrips/ three leaves) were found most effective whereas, the treatment of T9 (25% N through FYM + 75% through urea) with 6.53 thrips per three leaves and T10 (50% N through FYM + 50% through urea) with 6.11 thrips per three leaves proved least effective and both were at par. The maximum fruit yield of chilli was also obtained in these treatments which exhibited 86.52, 84.79, 83.85 and 82.54 q ha-1, respectively while, the minimum was found in the treatments T9 (25% N through FYM + 75% through urea) and T10 (50% N through FYM + 50% through urea) was found least effective resulted in 62.57 and 63.61 q ha-1, respectively.
