UTILIZATION OF BIO-N IN CORN PRODUCTION

DESCRIPTION:

The utilization of BIO-N in corn production increases yield while reducing the cost. This was proven thru an on-farm-research initiated by the Department of Agriculture (DA) XI conducted in Bansalan, Davao del Sur and Laak, Compostela Valley.

DETAILS:

The Department of Agriculture (DA) Regional Office XI has introduced the utilization of BIO-N to increase corn production while reducing cost. The effectivity of using BIO-N was proven by an on-farm-research recently conducted in Bansalan, Davao del Sur and Laak, Compostela Valley. By using BIO-N, more than half of fertilizer (particularly nitrogen) application has been cut down.

BIO-N is a solid inoculant in powder form that contains two important strains of bacteria capable of converting atmospheric nitrogen (N2) into a form usable by rice and corn plants. BIO-N contains bacteria that can enhance root development, growth and yield of rice, corn and other crops. This was developed by the National Institute of Molecular Biology and Biotechnology.

BIO-N is used by simply mixing or coating seeds or as suspension for use in watering seedbeds or as a root dip. BIO-N comes in a handy 200 gram packet. Five to six packets are recommended to inoculate rice and corn seeds or rice seedling enough to plant a hectare of land. Significant effects on rice and corn inoculation can be obtained in the presence of ¾ to ½ of the recommended amounts of inorganic N.

BIO-N also enhances yield of rice and corn where organic fertilizers have been applied basally. BIO-N has also been shown to work with other crops such as onion, squash, pechay, melon, tomato, eggplant and okra.

The tables below show the yield of corn fertilized with chemical or BIO-N and the cost and return analysis of using BIO-N.
