To assist the farmers improve crop yields amidst the skyrocketing worth of fertilizer within the world market, the Division of Agriculture (DA), by means of the Philippine Rice Analysis Institute (PhilRice), is selling the usage of biofertilizers and biostimulants together with inorganic fertilizer.
In a fertilizer derby, carried out by DA-PhilRice, outcomes confirmed that the mixtures of biofertilizers and/or biostimulants with inorganic fertilizers within the three to 4 seasons resulted in excessive yields whereas decreasing the fertilizer value per kilo of palay produced.
“We’d like extra manufacturing of scientifically examined biofertilizers as we’re involved that the Ukraine-Russia battle will disable us from getting the much-needed urea our farmers are clamoring to acquire,” mentioned Agriculture Secretary William D. Dar.
“Biofertilizer merchandise, akin to those used within the trials are the applied sciences that we want in our marketing campaign for balanced fertilization, the primary focus of which is to reinforce soil-based productiveness, bringing about nutrient-building qualities of the soil for soil sustainability,” he added.
Within the PhilRice trial, one mixture resulted in 7 tons/hectare (t/ha) produced at P7.77/kg. The associated fee amounted to P2,000/ha along with inorganic fertilizers. One other mixture resulted in 6.73 t/ha with P8.18 value/kg whereas one mixture yielded 6.35 t/ha at P7.71 value/kg. All three merchandise carried out higher throughout the dry season with a mean yield of seven.91 t/ha at P7.33 value/kg and throughout the moist season with 5.22t/ha yield at P8.58 value/kg.
Participated by largely personal corporations, the derby goals to find out the most effective nutrient administration expertise bundle to realize excessive yield not less than value in a worthwhile and environmentally-sound method. The expertise packages of most contributors included a mix of inorganic fertilizers and different merchandise akin to biofertilizers and biostimulants, soil conditioners, and micro-elements for foliar purposes.
In response to PhilRice, the present value of utilizing biofertilizers/biostimulants ranges from P900 to P6,900 per hectare relying on the variety of purposes.
Leylani Juliano, one of many mission leaders cited that the primary product’s composition primarily based on the evaluation offered by the Fertilizer and Pesticide Authority (FPA) included brassinosteroid, triacontanol, small concentrations of different components akin to iron, potassium oxide, copper, zinc, Vitamin B1, B2, B6, and has a liquid focus microbially synthesized from plant supplies.
The second product is a mixture of natural supplies and root exudates or fluids, which the manufacturing firm claimed can create wholesome soil by growing the presence of useful micro organism and fungi and can inhibit inhabitants of dangerous microbes within the soil.
The third product is a nanobiofertilizer, which incorporates nitrogen, phosphate, soluble potash, different supplies akin to algae, micro organism, fungi, sea kelp, mineral electrolytes, and humic & fulvic acids. Apart from the primary product, these merchandise lowered the usage of inorganic fertilizer by 25-50 p.c.
Juliano elaborated that most often, varied supplies can be utilized as biostimulants/biofertilizer akin to algae extracts, humic acids, enzymes, hormones, and plant growth-promoting microorganisms.
“Numerous researches present that pure biostimulants can improve diet effectivity in vegetation and general plant progress in addition to enhance soil circumstances to spice up the expansion of the rice vegetation,” Juliano mentioned.
Different mixtures achieved a mean yield of 5.83 t/ha – 6.25 t/ha with common manufacturing value of P7.79/kg – P8.08/kg of paddy produced within the three to 4 seasons of the derby. The derby’s fifth season is ongoing.
“With the worldwide worth hike of fertilizer because of the ongoing Ukraine disaster, the DA welcomes extra choices of fertilizer and different inputs to enhance fertilizer availability whereas pushing for balanced fertilization technique,” the agri chief mentioned.
Secretary Dar has been a long-time advocate of balanced fertilization, stressing that to realize the utmost potential of farmlands, a considered mixture of natural and inorganic inputs is critical. ### (PhilRice/DA-StratComms)
