The present study was undertaken with an objective to determine the impact of climatic variables on the population of Trichoderma sp. in the rhizosphere of black pepper. Rhizosphere soil samples were obtained from pepper plantation at a monthly interval for one year. Trichoderma sp. population were assessed at monthly interval along with weather parameters from July, 2015 to June,2016. The number of Trichoderma sp. were maximum in July and lowest in June. The correlation between weather parameters on the population of Trichoderma sp. revealed that the population increased with an increase in rainfall and relative humidity, whereas it decreased by an increase in temperature. The results of the present studies showed that climatic variables affect the population of Trichoderma sp. in the rhizosphere of black pepper. However, further studies are needed to confirm it.
