Abstract EN
The importance of fertilizer especially nitrogen for cereal crops to increase the yield without or with less input is consider the goal of producers.
Wheat crop (Triticum aestivum L.
) is the first cereal crop for the food basket of the world people, thus it is important to determine the N-fertilizer recommendation at Thi-Qar rejoin by reevaluate the previous recommendation by using optical sensor.
Therefore, this experiment was hold to study the effect of five levels of N-fertilizer (zero N add as control, 50, 100, 150, 200 kg N ha-1) on the yield of winter wheat.
Wheat cultivar (Bora) was planted at two fields (the first one located at Alshatra city- north of Al-Nassiriya city and the other one was at Al-Fadliya city- south of AL-Nassiriya city).
RCBD experimental design was used in this study and also used Handle GreenSeeker to measure NDVI, which it used to study the response index (RI) and In-Season Estimate Yield (INSEY).
Grain Yield kg m-2 was evaluated.
The results showed that RI was 4% at the first yield and 2 % at the other field, and there was a significant correlation between INSEY and grain yield (r2=0.82) for both fields.
Predicting yield could be evaluated at early growth stages FK4 as well as at booting stages FK8.
The best grain yield was recorded from the highest level of N-fertilizer in which it did not differ from the treatment 100 kg N ha-1.
We noted that should make to each field N-fertilizer recommendation because of different in soil characteristics, thus the fields at Thi-Qar rejoin need to be study to give a good recommendation to N-fertilizer to get the highest yield.
