Corn growth performance in response to Nousbo Controlled Release Fertilizer application in Malaysia. Research summary

 

 

(Summary of the study of Nousbo CRF 28-5-10 effect on Corn growth and yield attributes in Malaysia)

 

 

 

 

Nousbo CRF 28-5-10 is a fertilizer which each grain is coated with polymer that can control the rate, pattern and duration of nutrient release and contains all NPK required for plant growth and development. CRF 28-5-10 was evaluated for its efficacy as one-time application product for complete nutrient supply for Corn from March to July, 2019 in two locations with similar soil properties: MARDI Serdang and MARDI Cameron Highland, Malaysia, in order to determine the effect of Nousbo CRF on the growth and yield of Corn and to confirm the effective rate of CRF that will produce the highest yield.

Nousbo CRF 28-5-10 was tested using the following treatments: Control (without fertilizer), Recommended Rate of Conventional Fertilizer as basal and side dressing and Nousbo CRF at 3, 4 and 5 g/plant application rates applied once at basal. The values of Plant height, SPAD, Leaf fresh weight, Root dry weight were measured at 45 days after transplanting and Corn weight without husk leaf, Corn length were assessed at harvest. Results are summarized in the following table.

 

 

 

 

Yield and growth parameters of Corn as affected by treatments in Serdang and Cameron Highland

 

 

 

 

 

Vegetative growth results show that the advantage of CRF versus conventional fertilizer was clearly realized at 45 days after transplanting. It is obvious that the rate of CRF at 5 grams/plant was better than that of conventional fertilizer treated plants in all aspects of vegetative growth in terms of plant height, SPAD values, leaf fresh weight, root dry weight in both locations. This gives CRF user a potential of having improved yield ultimately if the rate of 5 grams/plant is used. The weight of marketable yield obtained in plants treated with the highest dosage of CRF exceeded significantly that of the value of the crops treated with conventional fertilizer.

 

 

 

 

 

 

 

 

The average advantage of 5g/plant CRF-treated plots over conventional fertilizer- treated fertilizer was 10.3% for the Serdang experiment and 9.5% for the Cameron experiment. It can therefore be recommended that the rate of CRF at 5 grams/plant assuming an economic advantage of conventional fertilizer could replace the existing fertilization practices.
