Rice production efficacy after treatment with Nousbo
One Time Paddy in Vietnam. Research summary

 

 

(Summary of the study of Nousbo One Time Paddy effect on Rice growth and yield
performances in Vietnam)

 

 

 

 

Nousbo One-Time Paddy (29-4-6) is a slow release fertilizer, that requires only one time application until harvest and promotes the growth and development of roots. It contains humic acid to promote proper soil aggregation and fertility. In order to evaluate the effects of One-Time Paddy on rice (indica), including the growth disease and pest resistance, yielding parameters, the trial was carried out from August to November 2017 at the Hau Giang Agricultural Hi-Tech Park, Hamlet Vinh Vien, Long My district, Hau Giang province, Vietnam. The rice variety used for this experiment was OM 5451 from Cuu Long Delta Rice Research Institute.

The recommended rate of conventional fertilizer was applied at 12 days after sowing (DAS) as 7kg/1300m² of Urea and 3kg/1300m² of DAP, at 17DAS as 5kg/1300m² of Urea, 4kg/1300m² of DAP and 3kg/1300m² of NPK 25-25-5, at 40-45DAS as 12kg/1300m² of NPK25-25-5(12kg/1300m²). Nousbo One Time Paddy was applied at 22-25DAS at the rate of 39 and 26kg/1300m², after application of Urea and DAP at 12 and 17DAS at the rate of 5kg/1300m² each every time.

The following parameters were gathered: plant height, number of shoots and grain yield. Plan height of 10 shoots was measured using the measuring tape from the rice root to the highest peak. Number of shoots was evaluated by counting all shoots in the frame (25x30 cm). For grain yields measurement yield was collected from 3 frames (2x2.5m). After that, rice yield was threshed, dried, cleaned, weight and measured moisture separately at the lab. Results are summarized in the following table.

 

 

 

 

Yield and growth parameters of Rice affected by One Time Paddy fertilizer in Vietnam

 

 

 

 

The effectiveness of One Time Paddy showed significant effect on the yield of Rice in Vietnam. The height and number of shoots of rice treated with Nousbo-One Time Paddy were higher than that of rice on control about 2.8cm and 22 shoots/m², respectively. The yield of rice treated with the Nousbo-One Time Paddy was increased by 0.85 tons/ha (18%) compared with control rice. In total, the Nousbo-One Time Paddy initially shows positive effects on the growth and yield of rice growing at the Hau Giang Agricultural Hi- Tech Park
