摘要：Global warming has recently been highlighted as a major threat for all the living beings on earth. In the current scenario the agriculture ecosystem significantly plays a role in global warming, indirectly, because of heavy quantities of chemical fertilizers and pesticides used to increase the yield. Through the increasing use of nitrogen fertilizer, which is added at a rate of 1 billion tons per year presently to the already existing amount of reactive nitrogen. Nitrous oxide (NO), has become the third most important greenhouse gas after carbon dioxide and methane. For reducing above mentioned problem in agriculture ecosystem, IPM (Integrated Pest Management) is one of the most suitable programme which establishes chemical use on a need basis only. The current study based on chickpea crop field for controlling Helicoverpa armigera (Hub.) through some IPM techniques during 2009-2010, revealed that first appearance of Helicoverpa armigera larvae in IPM treated plot was in the 2nd week of February while in control plot (with net) it was in 2nd week of January. The total grain yield in IPM plot was 15.20 q/ha whereas in control plot (with net) it was 10.12 q/ha recorded. The maximum number of larvae/10 plants in control plot (with net) was 24.0 but in IPM treated plot the maximum number of larvae/10 plants was only 10.33 recorded. Hence we can combat with global warming through IPM techniques by minimizing the quantity of chemical insecticides and fertilizers.
