Estimation of Acreage & Crop Production through Remote Sensing & GIS Technique

1. Estimation of Acreage & Crop Production through Remote Sensing & GIS Technique Presented By Abhishek Kumar Maurya Research Scholar Mahatma Gandhi Chitrakoot Gramodaya Vishawavidayala Satna (M.P.)

2. Introduction Soybean is an important crop in Madhya Pradesh. The crop is grown in average 21.88 lakh hectare areas. The production and area can be estimated in a very concise method and in very less time with maximum accuracy. Remote Sensing technique provides a methodology to map areas of Soybean field with the help of MODIS (TERRA) Satellite data and GIS (Geographical Information System) database. MODIS (Moderate-Resolution Imaging Spectroradiometer) satellite image offers a large choice of opportunities for operational application in a large area. Study area is selected and located with the help of time series (June 1st week to October 2nd week MODIS Images) which provides maximum accuracy. A concept of assessing areas of potential cultivation of Soybean is suggested by means of GIS technique. Integrating MODIS data with GIS techniques and time series based assessment (June 1st week to October 2nd week) the actual areas of Soybean fields have been mapped and yield production have been predicted. The Soybean acreage area and production accuracy is 80.72% and there is a 7% increase (compared to 2006) in 2007.

7. Acreage Estimation District wise acreage estimation of Soybean was done by using the following mathematical calculations- 1. Area in meter2 =Numbers of pixels of clusters * Resolution of the image 2. Area in hectare= Area in meter2 / 10,000 3. For MODIS - Area in meter2 =Numbers of pixels of clusters * 250*250

10. Result The process indicated in methodology has been used to extract the Soybean area in parts of Madhya Pradesh. The estimated Soybean area of Madhya Pradesh (districts-wise) is given in the table below. On the image, green color is assigned to Soybean in the table here gives the pixels and calculated area in parts of Madhya Pradesh district wise in Table 2.

12. Table-3 Comparison of acreage of year 2007 with acreage in the years 2005 & 2006

13. The total acreage of soybean estimated using Remote Sensing and GIS techniques in the different major districts of Madhya Pradesh is 26.5 in Lakh ha. Based on the satellite derived estimates of soybean acreage, Ujjain district has been adjudged the largest grower of Soybean during the current Kharif season with an estimated acreage of 421,106 ha. The other two major soybean growing districts, Shajapur (3, 08,087 ha) and Sagar (3,07,331 ha) have almost similar acreage of area under soybean. In Bhopal, although the acreage under soybean has increased as compared to last two years, but it is still the district with least acreage of soybean among the districts under study.
