Traditional use of areca

: SANTAL: (i) a patient of small pox is given to eat the areca nut when the pustules subside; (ii) a mixture for biliary colic is prepared with areca nut as a constituent; (iii) an ointment for chancre and syphilis is made by pestling areca nut with the root of Gymnema hirsutus, leaf of Piper betel and then cooking the same in mustard oil or butter; TRIBALS also use this plant in rhagadas, venereal sores, syphilis, dysentery, cholera, small pox and for fractured bones.
References to this plant are found in the BHAGVA TA along with the plants of Musa paradisica and Borassus fIabellifer. CHARAKA SAMHITA : Fruit: useful in the diseases caused by bile; SUSHRUTA SAMHITA : Fruit: beneficial in the diseases caused by phlegm; but overuse of this may distort voice of a man; CHACRADATTA : Paste of unripe fruit: may be used as liniment; Extract of unripe fruit: useful in small pox; HARITA SAMHITA : sesame oil in which extract of unripe fruit has been boiled should be used; A YURVEDA : various preparations of unripe and ripe nuts are useful in toothache, pyorrhea, gum diseases, in treatment of worms, while extract of young leaf mixed with mustard oil is useful as liniment in rheumatism; BRAHMAVAIVARTA PURANA : brushing the teeth with twig of this plant is beneficial; AGNI PURANA : (i) immortality can be attained by consuming decoction of this plant along with the powder of root, bark, leaf and fruit of margosa and juice of Wedelia calendulacea; (ii) alkaloids of this plant are beneficial medicine.

ARECA Crop management

Fertilizer recommendation: for areca  plant  
Chemical fertilizer recommendation /plant/ year
100g of N (220g urea)


40g of P2O5 (200g rock phosphate)


140g of K2O (225g muriate of potash)


Should be applied in two split doses


Organic fertilizer
12 kg each of green leaf and compost/plant/year


Weed Control
Research in India has shown that cultivations free of weeds gives better yield


Mulching
Mulching is a regular operation practiced in areca nut gardens in India. It keeps the plant base moist, reduces erosion and keeps the weeds under check. Chopped areca leaves and husks, grass or dry leaves are used for mulching.

What is pH?

Acidic and basic are two extremes that describe chemicals, just like hot and cold are two extremes that describe temperature. Mixing acids and bases can cancel out their extreme effects; much like mixing hot and cold water can even out the water temperature. A substance that is neither acidic nor basic is neutral.
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic.
Pure water is neutral, with a pH of 7.0. When chemicals are mixed with water, the mixture can become either acidic or basic. Vinegar and lemon juice are acidic substances, while laundry detergents and ammonia are basic. Chemicals that are very basic or very acidic are called “reactive.” These chemicals can cause severe burns. Automobile battery acid is an acidic chemical that is reactive
The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value. For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8.

Agribiotech conclution -PH value is very very important in agriculture fertilizer and fungiceides becuse -each whole pH value below 7 is ten times more acidic than the next higher value

Agribiotech conclusion.-Natural Fertilizers Vs. Chemical

Most of the fertilizers called "chemical" occur naturally in Nature. In fact, that is where man discovered them  Ammonia, ammonium, ammonium sulphate, nitrites, nitrates, potassium sulphate, calcium phosphate, urea are some of them. But  RARELY  are these chemicals found in the pure state. In Nature, they are almost always bound up in rock or in an organic form with other elements. Or they may be found in a state of transition


Natural fertilizers are rich organic sources of these elements, but chemical fertilizers get these nutrients from artificial compounds. Chemical fertilizers also typically have high levels of acids that are used to control the pH balance in the ground. so if u take care about ACID LEVEL ( PH ) WHILE USING CHEMICALS IN AGRICULTURE THEN IT IS NOT HARMFULL  TO UR LAND ,TOO ACIDIC IS TOXIC TO PLANTS 

Natural Fertilizers Vs. Chemical

A fertilizer maintains a healthy soil composition by stimulating microbial activity, protecting roots and facilitating plant growth. But when it comes to selecting a product, you should consider a few things in terms of the fertilizer's ease of use and ingredients. Whether a fertilizer is comprised of natural or chemical compounds, it can have certain drawbacks and benefits.

Availability

• Natural fertilizers can be derived from household products or waste. Compost, manure, mulch, grass clippings, wood ash and even coffee provide effective fertilization treatments when applied to soil. Chemical fertilizers are widely available to consumers in mass-market retailers.

Composition

• In order to work as an effective fertilizer, a solution needs to have calcium, magnesium, iron, nitrogen, phosphorus and potassium. These elements facilitate plant growth by stimulating the activity of beneficial microbes in the soil. Natural fertilizers are rich organic sources of these elements, but chemical fertilizers get these nutrients from artificial compounds. Chemical fertilizers also typically have high levels of acids that are used to control the pH balance in the ground.

Use

• Since natural fertilizers do not contain synthetic chemicals, they are generally safer for handling and close contact. Meanwhile, gardeners need to be conscientious of their exposure to chemical fertilizers because they can have caustic effects. And although natural fertilizers are less likely to contaminate the water table, they are more likely to be washed away with the rain. As a result, they need to have a deep, regular application in order to work as effective treatments.

Regulation

• Natural fertilizers can also be found in specialized products that are synthesized from green ingredients. These products are typically confined to specialty stores and online shops. But consumers need to consider the ingredients in these products to ensure that they are purchasing a green alternative. A fertilizer can still be marketed as "natural" or "organic" even if it is formulated with carbon-based compounds. And when it comes to chemical fertilizers, consumers should make sure the solution complies with their community guidelines. Due to concerns over water pollution, some products may be banned in regions with phosphorus-free fertilizer regulations.

Organic (Natural) and Chemical (Inorganic) Fertilizer ;;:

The argument continues. The organic proponents say only organic should be used. The chemical proponents have their argument of high analysis and quicker availability.

Why don't we consult Nature and see how she has been feeding plants life since the very beginning?

Most of the fertilizers called "chemical" occur naturally in Nature. In fact, that is where man discovered them. Ammonia, ammonium, ammonium sulphate, nitrites, nitrates, potassium sulphate, calcium phosphate, urea are some of them. But seldom are these chemicals found in the pure state. In Nature, they are almost always bound up in rock or in an organic form with other elements. Or they may be found in a state of transition.

Man-made chemical fertilizers always have a high total NPK, from 20 to 60 percent or more. The total NPK for organic fertilizer blends will always be low. Fourteen percent is about as high as it gets.

The balance of the ingredients in the chemical fertilizer bag, aside from the NPK, is usually made up of inert filler or possibly a chemical that isn't needed. The balance of the ingredients in the organic fertilizer bag beyond the NPK are all necessary soil nutrients. The fact that the material is organic means it came from a once-living entity-plant, animal or a blend of both-which tells us that every ingredient there is important to life. In the best organic fertilizers, everything in the bag is needed and is in correct proportions to feed and sustain the next generation of life.

Many chemical fertilizer formulas that contain major, minor and trace elements are labeled "Complete." That is really a false statement. It takes much more than a few chemicals to maintain the healthy soil and grow healthy plants. For example, there is very little, if any, carbon in a bag of chemical fertilizer. When a plant or animal body is analyzed, one of the most abundant elements in it is carbon, in the form of energy, mainly carbohydrates.

In order for a plant to be properly fed, whether with chemical or natural fertilizer, the microbial life in the soil must first process the fertilizer into a substance and release it in the correct amounts that are perfect for a plant to absorb. In order for the microbes to perform this service, they must have energy. They are not in the presence of sunlight, nor do they have chlorophyll like higher plants, so the microbes must get their energy from decaying plant or animal matter in the soil.

A bag of organic fertilizer has all the carbon/energy to meet the needs of the soil microbes. A bag of chemical fertilizer has no energy. If organic matter is not already present in the soil, the chemicals can quickly become stressful, even toxic, to the plants. This causes plants to be susceptible to disease and insect problems.

Organic fertilizers are believed to be slower acting than the chemical fertilizers. This is true to a degree. Being a lower NPK analysis and slower acting, organic fertilizers can be used in higher volume around plants without danger of burning. However, there are some organic fertilizers that are fast acting, such as bat guano or fish meal, that can show results as quickly as the chemical fertilizers do. They are still slower to burn the plants than the chemicals and last much longer in the soil.

Unless chemical fertilizers are impregnated or coated with a microbe inhibitor and some substance to keep them from quickly dissolving, they must be used very cautiously. Especially in sandy soils, they can burn the roots of the plants and quickly leach beyond the reach of the roots. They generally end up polluting a water supply because they are too quickly dissolved and moved out of the soil. In heavy clay soils or any soil with a high organic and humus content, this is less of a problem.

Chemical fertilizers that are blended to perfectly fit a given soil and then used in the correct season and correct amounts can do nothing more than grow a plant. They do not build or sustain a healthy soil. Organic fertilizers contain the energy and the many other things that continually build soil fertility, crumb structure, increased water holding capacity, food for all the beneficial soil life, condition the soil and contribute to the hundreds of other yet-unknown things that cause a plant to grow healthy and perfect.

Only healthy and perfectly grown plants can feed and support healthy and perfect animal and human life.

Reasons to fungicides fail

One thing to consider is inaccurate disease diagnosis. There are common problems that may be misidentified as fungal diseases including insect damage, chemical injury, bacterial diseases, nematodes, and environmental damage  Fungicide applications do not affect these other problems.
do not use dated fungicide material. The general rule is that fungicides stored over two years begin to lose their activity and may fail to work.

Loading fungicide in the sprayer

Mixing fungicides with too acidic or alkaline of water can reduce fungicidal activity, especially for water with a pH greater than 8.0. Optimally, water with a pH near 7.0 should be used for mixing pesticides. If water pH is not optimal, it easily can be corrected with pH buffers that are added to the water before mixing in fungicides.

For fungicides to effectively manage diseases, you must use them at recommended rates. In addition, care needs to be made when calculating treatment area and the amount of product to add to the tank. Be sure to carefully check the label before loading the sprayer and double check your calculations.

Mixing multiple pesticides in a spray tank can save time, but be sure they are compatible. Incompatibility can result in the formation of insoluble precipitates in your tank. Fungicide labels often contain information on mixing compatibility. If the label does not address compatibility, test a small volume of the spray mix in a glass jar for 30 minutes, and then look for separation or settling of pesticides in the jar. The order that pesticides of different formulations are added to the tank also may affect compatibility. Add different formulations of pesticides to the tank in this order: wettable powders, flowables, solubles, powders, surfactants, and then emulsifiable concentrates.

Fungicides begin to lose their activity if they sit too long in the spray tank. Fungicide activity declines within 12 hours after mixing and is accelerated by poor water quality (high or low pH).

Sprayer calibration and application

Perhaps the most common cause of fungicide-application failure is from incorrect sprayer calibration. If a sprayer is not properly calibrated, too much or too little fungicide can be applied, which can result in fungicide toxicity or unmanaged disease. To avoid these problems, recalibrate the sprayer after any modifications to nozzles, pressure, or speed are made. Also, the material should be applied in the recommended volume of water, at a constant speed, and at the recommended pressure. Be sure to adjust the spray pressure for the nozzles used. Excessively high sprayer pressures result in small droplets that may drift. Calibrating and adjusting a sprayer takes time, effort, and involves math, but it can save money and make fungicide applications more effective

Fruit rot or koleroga or mahali (Phytophthora arecae ):

The infection and spread of this disease is related directly to the incidence of heavy
rainfall. The disease first makes its appearance just after the first monsoon showers and
extends its stay throughout the monsoon period. A warm damp interval is always very
helpful for its rapid development. It attacks nuts of all ages and if unchecked will extend
to the crown of the plant ultimately bringing about its death.
The first sign of the disease is the appearance of patches of water soaked areas or rotting
tissue at the base of the nuts. The nuts darken and the patches enlarge and they begin to
drop in large numbers. These fallen nuts soon develop a whitish mass all over. If
unchecked, the disease may later invade the crown causing the leaves and bunches to die
within one or two seasons. The disease is carried forward in the remains of infected
materials lying in the gardens from year to year.

Management
 Spray 1% bordeaux mixture in 10 litres of water as  a prophylactic spray just
before the onset of the monsoon.
 Covering the bunches with polythene sheets in the month of June will also control
koleroga to a considerable extent
systemic fungicide  have exellent   protective activity against Phytophthora when spray before monsoon 


systemic fungicides need a minimum of 3 hours on the plant surface before a rain. Contact fungicides are always sensitive to rain but more so prior to drying on plant surfaces.

some usefull informations about ARECA or supari

Arecanut or betel nut or supari (Areca catechu) is  an important member of the family 

Araceae. It is chewed, both as raw nut and after processing.  

Climate and area of distributio

Arecanut is basically a tropical plant commonly found in most parts of the NER, also in karnataka.,

The crop 

flourishes well at temperatures ranging from 14–36  ºC. Extremes of temperature and 

wide diurnal variations are not conducive for desirable performance. Wet tropical and 

humid climate is considered to be most suitable for its successful cultivation and growth

In northeast India, arecanut is extensively grown in Assam, Tripura and in the foothills of 

Meghalaya. It also grows well in the foothills of Mizoram, Nagaland, Manipur and 

Arunachal Pradesh. Arecanut is an important component of multi-storied cropping 

systems and considering its addictive properties

Growing season  

The best months for planting arecanut are during the pre-monsoon period of May–June 

with the onset of the monsoon. It can also be planted in September–October provided 

there would be some sources of water for irrigation

Nutrients 

Adequate supply of plant nutrients in the soil throughout the life of the crop is essential to 

get high yields. Hence an annual application of about 1–2 kg each of green leaf and 

compost or cattle manure per bearing palm is recommended. Green leaf and compost can 

be applied as a single dose in September–October. Irrespective of the age of the plant, a 

full dose of green leaf and compost or cattle manure should be applied from the first year 

of planting itself. The green leaf and compost or cattle manure may be broadcast around 

the base of each plant after weeding and mixed with the soil by light forking. Or it may 

be applied in basins around the palm, usually dug to a depth of 15 to 20 cm, and at 0.75 

to 1 m radius. In acidic soils, the required quantity of lime may be forked in during the 

dry months. 

Water requirements  

Most of the arecanut plantation areas in the region are rain-fed. Irrigation of arecanut 

plantation, at least in northeast India, is uncommon. However, it is observed that in some 

pockets of the region, farmers occasionally carry out manual irrigation by connecting 

their fields with upstream or nearby perennial streams, for watering the plants during the 

dry season. The practice is more common when the plants are still small. 

Smart thinking that will revolutionise your approach to agriculture forever.
