Special Practices on Crop Production (part 2)
Special production practices are unique ways by which plant growth can be improved for functional or aesthetic reasons through controlling the plant environment or its parts. Example of these special techniques are as follows:
3. FLOWER INDUCTION- from the word itself this practice helps the plant to induce even during off- season thus producing without time consideration. Great example of these is on mango and pineapple. It makes the flower of mango more uniform and abundant. Various techniques such as the use of chemical, potassium nitrate (KNO3) as flower inducer on carabao mango, modifying the photoperiod, pruning, and timing of irrigation are used in inducing flowers on plant. Thus, making the plant yield all throughout the year. But of course the effectiveness will always depend on the specific crops.
On the case of pineapple, flower induction makes the plant attain uniform maturity and also makes the time of harvest controlled in order to avoid too much production in some instances calcium carbide are deposited in the crown of each plant that is dissolved by rain is proven effective by some growers. Also, compress acetylene gas or a spray of calcium carbide solution (that generates acetylene) accelerate uniform blooming. A more advanced method is the use of the hormone, a-naphthaleneacetic acid (ANA) or B naphylacetic acid (BNA) which induce formation of ethylene. In recent years, B-hydroxyethyl hydrazine (BOH) came into use. Treatment is given when the plants are 6 months old, 3 months before natural flowering time. The plants should have reached the 30 leaf stage at this age(www. hort.purdue.edu/newcrop/morton/pineapple.html).
4.DESUCKERING- This special practice involves the removal of unnecessary suckers from the base of the plant to allow better growth of the remaining suckers. A very common technique of banana or abaca. This also aims to regulate the volume and schedule of production. In the case of banana specially on a plantation, only 3 to 4 suckers of varying ages, usually of 3 to 4 months interval, are retained per month at any 1 time.
