Pointers on Applying Flower Inducer to Mango Trees by Felix B. Daray
Simultaneous fruiting is possible nowadays with flower inducer. By spraying it to mango trees, not just more, but bigger fruits are produced.
Potassium nitrate is the generic name of chemical flower inducer in mango, and the chemical symbol for this compound is or KNO;. It contains 13% nitrogen and 46% potash, hence it is also called 13-0-46. KNO supplies the potassium requirement of the tree and in the process, induces flowering.
Another flower inducer used, nowadays is calcium nitrate (CaN). It contains 45% calcium and 15% nitrogen. It is affordable, yet the effect is just the same.
Here are some pointers on applying flower inducer to mango trees.
1. Flowering and fruiting vary, depending on the variety.
2. Chemical flower inducers should not be used under the following circumstances:
• when the tree is 10 years old or below
• when the leaves and buds are young
• when the tree is weak and sickly
• during rainy days
3. High dosage of flower inducer should be applied when the tree is healthy and starting to mature, the leaves and buds are maturing, and the weather is cloudy.
4. Use low dosage of flower inducer (1% - 2% of KNO;) when the tree is already mature, healthy, and has dormant buds; the leaves and buds are mature; and the weather is sunny.
5. Induce flowering once a year. However, if it did not flush during the fruiting time, spray again after harvest, but do not expect full bloom.
6. Spraying should be done when the tree and leaves are dry, and with no expected rain within the next six hours.
7. Use Apsa-80 as sticker.
8. Using the same formulation, spray again after two days to hasten the emergence of flowers.
9. From flowering to harvest, it takes 7 to 8 months to rejuvenate and accumulate nutrients for the next fruiting season.
10. Trees that have yielded in the previous season but have not flushed can be induced, but do not expect a full bloom.
In spraying potassium nitrate, prepare a 1% - 3% solution, depending on the condition of the tree. Or, mix 4 kilos per 200 liters of water. Spray it onto the leaves and branches, totally wetting but not dripping. Spray early in the morning (from sunrise to 9:00 a.m.) or late in the afternoon (from 4:00 p.m.-6:00 p.m.) to prevent leaf burning due to sunlight. In applying CaN, one one hand, mix 5 kilos to 200 liters of water.
After 12 days, when the flowers start to emerge, spray pesticide and fungicide. The flowers would be fully opened after 20 days. At this time, the flowers are susceptible to pest, so inspect the plants every day to see if there are damages caused by insects, and spray appropriate pesticide.
Applying flower inducer at the right time and amount indeed results in significant increase in production. One mango farmer in San Roque, Digos City, Davao del Sur who uses inducer is Arnold Nebria. In fact he is the first one in San Roque who has succeeded in mango farming. At present, he grosses an average of PI million every harvest. Also applying inducer is Victorino Ramos, and in September 2008 this 70-year-old farmer and councilman of San Roque has earned almost P1 million.
In the same year, I grossed P960,000 from my 2-hectare lot planted to grafted Cebu Mango; and it was the biggest income that I ever earned in my entire life! So consider the said tips on using flower inducer, and you, too, would have a hefty profit.

Growing Pechay in PotsGardening has always been a favorite pastime of many people including me. That’s simply because it’s a relief from stress and brings joy, especially when it’s harvest time.
I am growing pechay organically in my backyard. I have 15 pots planted to pechay, and I enjoy sharing my harvest with my friends and neighbors. Likewise, I want to share my little knowledge on backyard gardening for the benefit of those who are interested in it, too.
I suggest to those who are planning to establish a garden to select an area that is exposed to sunlight and is near the kitchen. With the garden being one stone’s throw away from the kitchen, it would be convenient to water the crops with rice wash or with fish or meat wash, which are all good for the plants as these contain nutrients and minerals. Preventing infestation would be easy, too, as it would be easy to see
from the kitchen window the condition of the crops.
I also suggest that they construct a stand to elevate the pots to maximize use of space. Fill the pots with humus soil or compost. Plant one seed in small pots and two in bigger pots through direct seeding. When the pechay begins to sprout, start to water the same with either rice wash or fish- wash or meat wash.
As for pest management, I inspect my pechay plants every morning to see if there are tiny holes or scratches on the leaves. These are indications that the plants are infested with small pin worms or cutworms. I remove these greenish black worms using a stick and puller.
I start to harvest after 30 days. I do not uproot pechay plants until these start flowering. Pechay grow up to four months. Replace the soil in the pots with new garden soil and replant again.
