Corn yield increased after treatment with Nousbo Controlled Release Fertilizer in Philippines. Research summary

 

 

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

 

 

 

 

Proper use of fertilizer to satisfy plant needs is one of the component-input to increasing corn yield due to its content of several macro and micronutrients which are becoming deficient under natural ecosystem. Use of newly formulated Nousbo controlled release fertilizer (CRF) 28-5-10 can be a good alternative over conventional fertilizer due to its ability to provide nutrients in a controlled manner. Nousbo CRF 28-5-10 is a fertilizer in the form of granules coated with material that can control the rate, pattern and duration of plant nutrient release. 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, CRF 28-5-10 was evaluated for its efficacy as one-time application product for complete nutrient supply for Corn from June 2018 to November 2018 in two locations in Philippines: Barangay Caurdanetaan, Umingan, Pangasinan (Barangay) and Barangay Bantug, Science City of Munoz, Nueva Ecja (Barangay Nueva Evja).

The recommended rate of conventional fertilizer was applied based on soil analysis recommendation at the rate of 120-20-30kg NP2O5K2O per hectare in Barangay and 120-40-30kg NP2O5K2O per hectare in Barangay, Nueva ecija, applied as basal and top dressing. Inorganic fertilizer sources were complete fertilizer 14-14-14 and Urea 46-0-0 and Muriate of Potash. CRF 28-5-10 was applied once as basal through dibbling. The following data were gathered: plant height(cm) at 30DAT, total number and weight of harvested marketable corn ears and computed yield (tons/ha). Results are summarized in the following table.

 

 

 

 

Yield and growth parameters of Corn affected by various kinds of fertilizers in Barangay and Barangay, Nueva ecija

 

 

 

 

Highly significant effect on the different agronomic and yield parameters of corn were observed from plants treated with CRF in both locations. Application of CRF 28-5-10 at the rate of 5g/hill applied as basal in Barangay location produced the tallest plants at 30 DAT (103.10cm), highest number (around 91 corn ear/plot with highest weight (18.62kg/plot)) of marketable ears per plot and highest computed yield (11.64tons/ha). Insignificant differences on the above agronomic characteristics were obtained from the application of CRF 28-5-10 at the rate of 4g/hill. Similar result was observed in Barangay, Nueva ecija location. Application of CRF 28-5-10 at the rate of 5g/hill applied as basal in Barangay, Nueva ecija location produced the tallest plants at 30 DAT (82.92cm), highest number (around 81 corn ear/plot with highest weight (16.58kg/plot)) of marketable ears per plot and highest computed yield (10.36tons/ha).

 

 

 

 

(Yield quality of Corn affected by various kinds of fertilizers)

 

 

 

 

Application of CRF at the rate of 5g/hill applied as basal produced the tallest plants at 30DAT, highest number and weight of marketable ear and highest computed yield. Plants applied with CRF 28-5-10 at the rate of 4g/hill produced statistically similar result. Findings showed that the recommended rate of CRF 28-5-10 for corn production is 4-5g/hill applied as basal through dibbling.
