Using chlorophyll meter for Nitrogen Recommendation of wheat

Nitrogen is the most important nutrient for wheat growth and it is as primary nutrient element for plants. Time and amount of N application is an important factor to meet the plant requirement, farmer economy and environmental aspects.In the recent years, the chlorophyll meter has been a new device which can help the farmers to recommend the nitrogen fertilizers rapidly. This greenhouse experiment was conducted in a completely randomized design with six different treatments (0, 50, 100, 150, 200, 250 N Kg/ha) in nine replications.Wheat (Triticum aestivium L) sampling was done from the early growth stages up to the harvesting time. Total N, N-No3 were determined in this samples (soil, plant).The chlorophyll meter reading data were collected during the wheat growth. The results shoued that N application had significant effect on the chlorophyll content of leaves. The critical value of chlorophyll meter reading was 48.5 for this experiment. In this study 100 Kg/ha urea had the highest yield.This research was conducted for the purpose of preventing the uncontrolled use of nitrogenon fertilizer and environ mental pollution.
