Agriculture in India is mainly dependent on the monsoon and its rainfall patterns. Uttar Pradesh is a major food grain producing state of the country contributes about 21 Percent of total food grain production. The Major crop grown in state during kharif season is Rice. Productivity of rice is almost stagnant from since last ten years. State experiences frequent droughts, floods and dry spells during the monsoon season behind these vulnerabilities rainfall is the key climatic element. Prediction and modeling of rainfall is very important issue for atmospheric sciences and agriculture. Hence a comprehensive analysis of rainfall data is a crucial component of the planning phase in agricultural research. Pattern of south west monsoon is directly related with the productivity of crop during monsoon season. Onset and withdrawl of monsoon govern the length of growing period for any particular region. Number of Dry and Wet days during monsoon period deals with management practice of crop. Probability of getting dry and wet days spell length during growing season helps to identify the windows for planning of sowing or planting date, irrigation, harvesting and several other management practices. Instat v. 3.033 is used to identifying these characteristics in the Central part of Uttar Pradesh.
