The soil of the experimental site was sandy loam in texture, slightly alkaline in reaction, low in organic carbon, and medium in available phosphorus and potassium. The experiment consisted of 5 treatments, viz., T1-Control, T2-75% Recommended Dose of Fertilizer (RDF), T3-100% Recommended Dose of Fertilizer (RDF), T4-125% Recommended Dose of Fertilizer (RDF), and T5-Based on Crop Sensor. The experimental results revealed that the treatment based on the Crop Sensor recorded the highest growth and yield attributes, i.e., plant height was 89.81 cm, number of tillers/m2 was 459 per square meter, grains per spike was 40.07, grain yield was 5.61 tonne per hectare, and straw yield 11.54 tonne per hectare. Higher net returns and B: C ratio was 3.68 which was recorded with the treatment based on the Crop Sensor, followed by T3-100% Recommended Dose of Fertilizer (RDF) whose B: C ratio was 3.63, during the year. Hence, based on the one-year study, it may be concluded that among the different sensor-based nitrogen application treatments, the treatment based on the Crop Sensor was found to be the most effective treatment in the economical control of nitrogen management in Raj-4238 wheat cropsEnglishThesis
