Copy link Agromaster Trial with Rice
61
Delta del Ebro, Spain 2021
61
Key Conclusions
Including Agromaster in the rice fertilizer strategy produced an increase of up to 15% in yield for an identical N rate; the same yield when the N application rate was reduced by 20%; and an increase of up to 61% in NUE.
Objective
The objectives of the trial are:
- to assess rice (Oryza sativa) Nitrogen Use Efficiency, and
- to compare the effect on the final rice yield of using a single application of Agromaster (a controlled release nitrogen-based product), with a split applications of conventional urea. Both treatments were tested at 2 different N application rates.

Treatments
The trial was carried out by Agricultura y Ensayo, in the Ebro river delta in Spain. The experiment consisted of a randomized block design with 4 replications.

Results
- Higher yields with the same level of N
Using Agromaster, statistically significant differences were registered in respect of yield – extra 15% at N rate of 200 kg/ha and 10% at 160 kg/ha. - Similar yield with less N (-20%)
Furthermore, when using Agromaster, at reduced rate (-20% of N rate), there is no detrimental effect in respect of yield. - Higher Nitrogen Use Efficiency with only 1 application
Thanks to the controlled release of nitrogen, only 1 application of Agromaster provides higher nitrogen use efficiency (NUE) compared to 3 split applications of conventional urea, in both fertilization strategies at 200 and 160 units of N per ha, respectively – extra 60% for the same kg of N applied.
Agromaster increased rice yield by up to 15%.
Agromaster increased nutrient use efficiency in rice by an impressive 61%.
Nitrogen Use Efficiency, calculated as Agronomy Efficiency = (Y–Y0)/F
Y = Yield of harvested portion of crop when the said nutrient is applied
Y0 = Yield of harvested portion of crop when the said nutrient is not applied
F = Application rate of said nutrient
