Copy link Rice Trial with Nova HiPeaK in China
38
China
38
Key Conclusions
- HiPeaK treatments gave the best results compared to the control and MKP treatments.
- HiPeaK was found safe for rice, with no signs of leaf deformities, distortions, seedling dwarfing, or leaf yellowing.
- Foliar application showed better results in seed number and yield.
- Drone application showed better results in plant height and seed weight.
- Better results were achieved with the highest HiPeaK concentration (foliar / drone).
Objective
- To evaluate the safety of different Nova HiPeaK concentrations applied on rice.
- To explore the effects of different Nova HiPeaK concentrations on growth period and yield of rice.
- To provide a scientific basis for promoting applications of Nova HiPeaK’s different concentrations on rice in cold regions.

Crop
Rice
Product
HiPeaK 0-44-44
Assessments
Plant height (cm), number of ears/m², number of seeds (per plot), 1000 grain weight (g), yield (kg/667m²)
Treatments
The trial was set up in China in 2020 in rice (Oryza sativa), cv. ‘Longjing 46’ and tested the efficiency of watersoluble fertilizer Nova HiPeaK compared to traditional MKP. Nova HiPeaK has a higher solubility which makes it suitable for use in low temperatures.
- Two treatments (one in jointing and one in booting stage).
- Three different concentrations (0.75, 1, 1.5 kg/ha) of Nova HiPeaK and MKP.
- Two forms of Nova HiPeaK applications (foliar spray and drone spray).
- All plots received the same base dose of a conventional fertilizer. The control plot received only the base fertilizer.

Results
Plant height
Rice plants grew the highest after the drone application of 1.5 kg/ha Nova HiPeaK.
Number of ears and seeds
The most concentrated foliar application of Nova HiPeaK gave the highest number of ears as well as seeds.
Grain weight
The highest concentration of Nova HiPeaK applied by drone resulted in the highest weight of 1000 grains.
Yield
Yields were highest after the foliar applications of Nova HiPeaK; with the highest concentration giving the best yield.
