| Summary, etc | A study was conducted to evaluate a site specific drip fertigation system <br/>based on the nutrient status maps prepared with help of GIS at Instructional Farm <br/>KCAET, Tavanur. Seventy soil samples were collected at a grid interval of <br/>50×50m and different soil parameters such as pH, Electrical conductivity, Organic <br/>Carbon, Available Nitrogen, Available Phosphorous and Available Potassium in <br/>the soil were determined. The nutrient index rating of the study area indicate that, <br/>nitrogen and potassium shows “low fertility”, whereas phosphorous found to be <br/>under “high fertility” range in the study area. <br/><br/>Using the spatial variability maps of the nutrients, two test plots, one from <br/>high fertility zone and one from low fertility zone were identified with the help of <br/>GPS for raising the test crop tomato. The experimental plot was laid out in a <br/>Completely Randomized Design (CRD) with four treatments and four <br/>replications. The results showed increase in yield and growth parameters under <br/>site specific drip fertigation treatment in low fertility area due to the adequate <br/>fertiliser application than general recommendation, which might be inadequate for <br/>that low fertility area. In case of high fertility area, reduction of fertilizer to site <br/>specific requirement has produced almost similar result of general <br/>recommendation which indicates that site specific dose was sufficient to produce <br/>optimum yield from the crop. Moreover, a site specific drip fertigation helped to <br/>achieve a higher water and nutrient use efficiency with high economic return of <br/>agricultural produce. <br/><br/>From this study, it can be concluded that nutrient status map prepared <br/>using GIS for a particular area can be used as an effective tool for the better <br/>nutrient management in that area for maximum productivity. Instead of going <br/>blanket nutrient recommendation, a site specific nutrient recommendation may <br/>help the farmers who want to achieve higher profit from unit land area by using <br/>optimum inputs, thereby reducing environmental stress due to over fertilizer <br/>application. |
