Gramin Krishi Mausam Sewa Regional Research and Technology Transfer Station(OUAT), Keonjhar, Odisha-758002, Email: monikarayouat@gmail.com Online published on 2 January, 2017. Abstract In India rainfall is the major source for the most sought commodity of water all over the world. India experiences a monsoon of four months making it more precious. The amount of rainfall received over an area is an important factor in assessing availability of water to meet various demands of agriculture. A direct relationship between rainfall and agricultural production exists in Indian agriculture, where more than 50% of cultivable land is rainfed. Rainfall has a pivotal role not only in agriculture but also in allied day-to-day activities. Every attempt is therefore made to study and analyse rainfall data in order to understand its distribution, pattern and characteristics.. The analysis of 36 years (1980–2015) daily rainfall data of Keonjhar district coming under North Central Plateau agro-climatic zone of Odisha has been done for determining the characteristics of rainfall, and probability of occurrence of normal weekly rainfall. Seasonal and yearly analysis of the rainfall was also done for the Keonjhar station whose annual average rainfall is 892.53 mm, with 52 numbers of rainy days. Top Keywords Daily rainfall, normal rainfall, probability analysis, rainfed agriculture. Top | |
