Graftage includes budding and grafting methods used to propagate fruit trees. Budding involves inserting a single bud from the desired cultivar into the rootstock and is usually done in late summer. Grafting joins a scion containing buds or shoots to the rootstock during winter dormancy. Both result in a tree with the scion cultivar but budding requires less skill and time. Knowledge of graftage techniques is important for fruit growers and nursery workers to propagate cultivars and preserve mutations. The document then provides detailed instructions for budding, grafting, and collecting and storing scion wood.
This document describes a new grafting method for propagating seedless watermelon plants. The method involves grafting cuttings from seedless watermelon scions onto rootstocks of different gourd varieties, including bottle gourd, pumpkin, and squash. The grafted plants showed increased growth, yields, fruit characteristics, and sugar content compared to seedless watermelon grown without grafting. The new grafting technique could help reduce the high costs of producing seedless watermelon in Egypt by providing a means of asexual propagation to minimize the need for expensive hybrid seeds.
This document discusses propagation of plants through grafting and budding. It describes reasons for using grafting and budding such as propagating plants that do not root easily from cuttings, changing cultivars, and repairing damaged plants. Key terms used in grafting and budding like scion, stock, and callus are defined. Factors that affect the success of grafting and budding are discussed, including the appropriate time of year, compatibility of the stock and scion, temperature, age of plant parts used, and care of grafted plants. Various grafting and budding methods are described along with tools and materials needed and handling of scion material.

Layering is a method of vegetative propagation where a stem is induced to root while still attached to the parent plant. There are several types of layering including simple layering, where a stem is bent to the ground and covered with soil, and air layering, where a stem is girdled and surrounded with moist moss to promote root formation. Layering has advantages over other propagation methods as it prevents water and carbohydrate stress on the new plant and ensures a high success rate. Factors like wounding, moisture, and growth regulators can influence the rooting of layers.

Selecting and Planting Fruit and Nut TreeseAfghanAg
This document provides guidance on establishing a fruit garden by selecting an orchard site, preparing the land, choosing fruit trees, and planting trees. The ideal orchard site has good drainage and a slope of 4-8% facing south. Soil tests identify fertility and potential pest issues. When selecting trees, factors like size, cultivar, rootstock and pollination requirements are important. Orchards are laid out with consideration of tree spacing, varieties, and placement of pollinizer trees. Proper planting involves digging a hole for the roots, placing the tree at the right depth, and filling in gently around it.
Layering is a method of plant propagation where stems are bent to form roots while still attached to the parent plant. There are several types of layering including simple, compound, trench, air, and mound layering. Simple layering involves bending stems to the ground to encourage root formation. Compound layering alternates buried and exposed stem sections. Trench layering uses permanent rows with stems pegged into trenches. Air layering forms roots from stems enclosed in moist material. Mound layering cuts plants back and mounds soil over new shoots. Layering allows propagation of plants that do not root easily from cuttings and produces genetically identical offspring to the parent.
This document provides information on cultivating citrus nursery trees including propagation, rootstock collection and seedling care. It discusses that grafting is commonly used to propagate trees and transmit diseases. It is important to use certified disease-free scion wood and control insect vectors. The document outlines best practices for collecting and treating rootstock seeds, growing seedlings, grafting, and caring for nursery trees to produce healthy plants free of viruses and diseases.
Topworking is a grafting technique used to repair or change the variety of fruit trees without removing and replacing the entire tree. The top of the tree is cut back to several major limbs and the stubs are then grafted or budded with the desired variety. Bark grafting is commonly used for topworking larger rootstocks, where several small scion pieces are inserted into slanted cuts in the bark. Bridge grafting is used to repair damaged bark areas, with scion wood attached across the injured part to reconnect the sections. Inarching is a similar repair method where healthy rootstock cuttings are planted next to the trunk and grafted on above the damaged area.
Propagation by cuttings, layering and divisionDebbie-Ann Hall
This document provides information on asexual plant propagation methods including cuttings, layering, and division. It discusses preparing rooting media and conditions to promote rooting. Various types of cuttings are described such as stem, leaf, and root cuttings. Methods of layering plants include tip, simple, compound, and mound layering. The document aims to inform readers on vegetative propagation techniques to reproduce desired plant varieties.
Layering is a method of plant propagation where a stem or branch is rooted while still attached to the parent plant. There are several types of layering including simple/ground layering, tip layering, trench layering, air layering, and mound layering. Factors like girdling the stem, applying rooting hormones, preventing light, and maintaining proper moisture levels can influence the success of layering. Layering allows plants to be propagated without detaching from the parent, providing nutrients and promoting higher survival rates compared to cuttings. However, it is a slower process that produces fewer plants compared to other propagation methods.
Breadfruit trees are commonly propagated through vegetative methods like root shoots, root cuttings, and air layering of branches. Root shoots and cuttings are collected from healthy roots after the fruiting season, when carbohydrate levels are highest. Shoots begin developing after 3-4 weeks and are transplanted when 20-25cm tall. Air layering involves removing bark from branches and wrapping with media to encourage root growth over 2-6 months. Seed propagation is rare as seedlings are not true to type. Young plants require shade but mature trees full sun. Careful acclimation is needed when transplanting.
Division is a method of plant propagation where the crown of the plant is separated into smaller pieces for propagation or rejuvenation. Each divided piece must have at least one bud and some roots. Benefits of division include acquiring several new plants and rejuvenating mature plants. Certain species like lavender and rosemary cannot be divided as they do not form crowns. The timing of division depends on when the plant blooms - spring bloomers are divided in fall and fall bloomers in spring, avoiding periods of active growth. Plants are divided when they have outgrown their space or have decreased flowering over years. Perennials form clumps over time and dividing allows producing several plants from one.
Raising Vegetable Plants from Seed for the School Gardenxx5v1
1) Raising vegetable plants from seed has several advantages over purchasing plants, such as being cheaper and avoiding the introduction of diseases into the garden soil.
2) Seeds of vegetables like lettuce, cabbage, and tomatoes can be sown from mid-January to early February in flats or containers kept in a warm room.
3) As the plants grow, they will need to be transplanted into larger containers and eventually into a plant frame by early March to harden off before being planted in the garden.
This document discusses vegetative propagation techniques of budding and grafting. Budding involves joining a bud (scion) from one plant to the stock of another plant of the same species. Grafting similarly joins the scion and stock, but uses a piece of stem rather than a single bud. Reasons for using these techniques include propagating plants that do not breed true from seed and controlling size or traits through the rootstock. Success requires compatible plant materials and proper technique matching vascular tissues. Aftercare such as watering and pruning is also important for graft and bud unions to form. Specific techniques like T-budding roses, chip budding fruit trees, whip-and-tongue grafting, and side v
Stem cuttings are the most common method of vegetative plant propagation. A stem cutting is a portion of a stem that includes at least one node and is rooted to form a new plant. There are several types of stem cuttings including softwood, semi-hardwood, and hardwood cuttings. Softwood cuttings are taken from new, succulent growth while hardwood cuttings are taken from dormant, mature stems. Leaf cuttings can also be used to propagate some plants by rooting leaf blades or sections. Proper environmental conditions and sometimes treatment with rooting hormones helps promote root formation on cuttings.
This document provides suggested cultural practices for growing the moringa tree. Some key points:
- Moringa is one of the world's most nutritious crops and has many uses for food, medicine, and more.
- It can be grown from seed, transplant, or stem cuttings. Spacing depends on the part of the plant being grown (leaves, pods, etc).
- Moringa grows in a wide range of climates and soils but prefers well-drained soil and temperatures between 25-35°C.
- Leaves, flowers, and young pods can all be harvested for food. Pruning encourages branching and higher yields.

Proper soil preparation, fertilization, and irrigation are essential for optimal watermelon growth and high yields.
This document provides instructions for growing native plants from seed and cuttings. Some key points include:
1. Native plant seedlings need strong light, light, and more light to thrive. Fluorescent shop lights placed close to the seedlings work well.
2. The soil mix is made mostly of peat moss, vermiculite, sand, and calcined montmorillonite clay to prevent damping off. Seeds should be planted at a depth twice their diameter.
3. Cuttings can be taken from plants throughout the year, with softwood cuttings taken in the growing season and rooted on a mist bench, and hardwood cuttings taken dormant season and stuck directly in
Moringa trees can be easily grown from seed or cuttings. They prefer full sun and well-drained soil. Seeds should be planted 1 cm deep and kept moist. Seedlings can be planted out when 60-90 cm tall. Moringa trees grow quickly, reaching 5 meters in the first year, and produce pods within 3 years. Regular pruning and pinching encourages bushy growth and maximizes pod production. Moringa is resistant to most pests and diseases.

chrysanthemum propagation and cultivation.pptbabu kakumanu
Chrysanthemum is a popular commercial and exhibition flower grown for its wide variety of sizes, colors, and forms. It is a short day plant requiring less than 10 hours of daylight and prefers sandy loam soil with a pH between 6.2-6.7. Suckers or cuttings are used for propagation. Pinching, disbudding, and destemming are practiced to control plant shape and flowering. Chrysanthemums require adequate fertilization and protection from various pests and diseases.
Carrots are a cool weather crop that originate from Asia. They grow best in deep, well-drained sandy loam soil with a pH between 6.5-7.0. There are several varieties of carrots suited for different purposes, with Imperators being long and slender and best for fresh markets. Proper cultivation practices include deep plowing, applying fertilizers like nitrogen, phosphorus and potassium, and irrigation to maintain soil moisture. Carrots are harvested when the roots reach sufficient size, usually 90-110 days after planting, and are graded and packaged for various markets.

Layering and grafting are vegetative propagation techniques for native plants. Layering involves bending stems to the ground to form roots while still attached to the mother plant, providing advantages like less maintenance than cuttings. Grafting joins parts from two plants so they grow as one, allowing benefits like changing varieties or taking advantage of particular rootstocks. Both techniques can help propagate native species when resources are limited.
Permaculture- Chicory Crop, Asteraceae family
Common chicory is a somewhat woody, perennial herbaceous plant of the dandelion family Asteraceae, usually with bright blue flowers, rarely white or pink. Many varieties are cultivated for salad leaves, chicons, or roots, which are baked, ground, and used as a coffee substitute and food additive.
Chicory root is primarily composed of inulin, a prebiotic that encourages the growth of healthy gut bacteria. Chicory is used for liver and heart health, constipation, swelling, and other conditions, but there is no good evidence to support its use. In foods, chicory leaves are often eaten like celery, and the roots and leaf buds are boiled and eaten. Chicory is also used as a cooking spice and to flavor foods and beverages.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Growing strawberries in_high_tunnels
1. Growing Strawberries in High Tunnels in Missouri
Lewis W. Jett1
Figure 1. High tunnel strawberry production research in Columbia, MO, 2006
Introduction
Strawberries are one of the most popular fruit crops produced in Missouri. The typical field
production season for this high-value crop is mid- to late May through June for matted row (open
field) berries. High tunnels may give growers the opportunity to produce early-season or late-
season strawberries in Missouri. High tunnels are unheated, plastic-covered, solar greenhouses.
Ventilation is passive through roll-up side walls or curtains and roof vents. Crops are grown in
native, mineral soil under the high tunnel. The high tunnel protects the growing crop from
environmental extremes such as wind, hail, rainfall, insects and diseases which allows for
significantly earlier and higher marketable yields. Since high tunnels have low startup and
operating costs, a single crop often provides enough revenue to pay for the cost of the structure.
Strawberry Culture
In 2006, I initiated a high tunnel strawberry evaluation using ‘Chandler’ variety. ‘Chandler’ is a
productive, plasticulture strawberry variety which performs well even as a field variety in
southern Missouri (Zone 5B and 6). ‘Chandler’ is relatively susceptible to anthracnose, a fungal
disease often triggered by rainfall.
Using plug plants obtained from Jersey Asparagus Farms, Inc. (see appendix), the strawberries
were planted in mid-September 2005 in each of four high tunnels (20 ft wide x 12 ft high x 36 ft
long) in Columbia, MO. Each high tunnel had a single layer of 6-mil plastic.
Rooted, plug plants are more expensive than using dormant runner tips, but good quality plants
with strong root systems are quick to get established. Dormant runner tips can be purchased
from many northern nurseries and rooted in 50-cell trays. Tips should be rooted in late August
since it will take approximately 4 weeks to develop a root system. To accelerate root growth, the
runners stubs can be dipped in a rooting powder (e.g., Rootone®) (Figure 2). Try to root runner
tips as soon as they arrive.
Figure 2. Strawberry runner tips should be rooted approximately 30 days before transplanting in a high
tunnel.
1
2. Each runner tip can be rooted using standard potting mix and 50-cell planting trays.
If there is variability in size of the runner tips, the larger tips can be rooted in a 38-cell tray.
After planting in trays, the plantlets can be placed in a greenhouse under a mist bed. Some
growers have had success rooting strawberry runner tips by placing the trays on a wagon in
indirect sun and watering twice daily.
A. Fertilizer and Soil Fertility
A soil analysis should be performed prior to planting strawberries within a high tunnel. The
optimal pH range for strawberries is 5.8-6.5. Preplant, granular fertilizer (10N-10P-10K) can be
broadcast over each raised bed prior to laying plastic mulch. Approximately 30-40 lbs (per acre
equivalent) of nitrogen is sufficient for strawberries which is 0.7-0.9 lbs of actual nitrogen/1000
ft2 of bed area. Generally speaking, a granular fertilizer (such as 13-13-13) broadcast over the
beds before planting is best, but if you choose to not apply fertilizer this way, you can apply a
soluble fertilizer (such as 20N-20P-20K) through the drip irrigation system. It’s very important
not to apply too much preplant nitrogen to strawberries (especially ‘Chandler’). Also, if a lot of
manure or compost has been applied to the soil within the high tunnel, no preplant nitrogen will
be needed. Excessive nitrogen will result in an abundance of branch crowns. When a strawberry
plant has too many branch crowns, the average fruit size is significantly reduced.
When the strawberries emerge from dormancy the following spring and resume growth,
additional nitrogen (approximately 5 lbs/acre/week equivalent of actual nitrogen or 1.8 ounces of
actual nitrogen/1000 ft2/week) can be applied via the drip system. At first flowering, a tissue test
should be performed by taking a few leaf samples from each high tunnel, drying them, and
sending them to a diagnostic lab for analysis. Always choose a recently mature leaf from a
single variety. Generally 20 leaves per high tunnel per variety will be sufficient. Consult your
local extension agent for details about sufficiency ranges for tissue tests.
Strawberries are especially sensitive to salt in the soil. Have the soil tested for soluble salts. Soil
salinity can be a problem if a lot of high salt fertilizers or animal manures are used over time.
Normally rainfall would leach these salts out of the root zone, but since the high tunnel excludes
rainfall, salts will accumulate. Salts within the soil make it harder for the plants to extract water
from the soil (Upson, 2006)
In the high tunnel, strawberries can be rotated with such crops as tomatoes or peppers. It is true
that both tomatoes and strawberries can share certain soilborne diseases (Verticilllium wilt).
However, as long as you don’t have a disease outbreak, rotation is flexible within the high
tunnel.
B. Spacing and Planting
Each plant was planted 12 inches apart within the row with rows spaced 12-15 inches apart.
Each row was offset from the other so as to produce a staggered planting arrangement (Figure 3).
All planting within the high tunnel was done by hand. After planting, apply a starter solution
(for example, 9N-45P-15K fertilizer) to encourage root growth. One of the keys to success with
high tunnel strawberries is obtaining an optimal plant population. A four-row bed with each
plant spaced 12-15 inches apart is an optional planting arrangement for high tunnels (Figure 2).
In a commercial high tunnel (2500-3000 ft2), approximately 1200-2000 strawberry plants can be
planted using the twin to four row planting arrangement.
C. Drip Irrigation
When there are 2 or more rows per bed within a high tunnel, 2-3 drip lines are essential for
uniform watering. This is particularly true with coarse or sandy soils. Each drip line can be
placed between each row on the bed. Choose drip lines with a 4-6 inch dripper spacing, and bury
the drip line about 1-2 inches in the bed with the drippers (emitters) facing upward. Burying the
2
3. drip tape protects it from rodents and prevents movement of the drip line in hot or cold
temperatures. If Queen Gil® drip tape is used, it must be buried to properly distribute water.
In early fall after transplanting, irrigate approximately 3-4 hours per week. When the weather
gets cool, and the plants are transpiring less, irrigation frequency can be scaled back. No
irrigation will be necessary during the winter months when the strawberries are dormant.
Irrigation can be scheduled using either an irrometer (tensiometer) or the “feel” method. If an
irrometer is used, the reading should be in the 20-30 cb range at the 12” depth. For details on
using the “feel’ method, consult the Midwest Vegetable Production Guide (Table 8).
It is essential not to over water strawberries since they do not thrive in waterlogged soils.
12 in.
Figure 3. Strawberries are planted on raised beds with 2 rows or 4 rows per bed. Each plant should be planted in an
alternate planting arrangement for maximum light interception.
Do not plant the strawberries too deep. I usually plant about midway up the crown, making sure
not to bury the crown (Figure 4). Strawberries should be planted within a high tunnel from mid-
September until mid-October in Central Missouri. Planting too late will result in less branch
crowns per plant, poor winter hardiness, and the plant may produce an abundance of runners the
following spring.
Proper planting depth
Figure 4. Planting depth for strawberries. CROWN
3
Anatomy of a strawberry plant.
4. D. Row covers
As the strawberries continue to grow in the fall, the crown grows producing 4-5 branch crowns
per plant. Each branch crown will produce about 10 flowers. These flower trusses directly
translate into marketable yield. However, it is important not to get too many branch crowns
since this will result in a lot of small fruit. Too many branch crowns could be formed if the row
covers are placed on the strawberries too early. Remove any runners or flowers which appear in
the fall. This channels energy into branch crown formation.
Figure 5. Row covers are used on strawberries for frost or freeze protection.
Row covers are lightweight blankets of spun bonded fabric which are placed over plants to
protect them from frost or freezes (Figure 5). Row covers (1 oz/yard2) provide 4-6°F protection
in the open field and nearly double that when used within a high tunnel. Using row covers on
strawberries is tricky. Extended use of row covers could cause the strawberries to bloom too
early resulting in lost yield. However, failure to use a row cover may result in freeze damage to
the crowns. If the winter season is mild, I would use row covers in a high tunnel only for freeze
protection (temperatures lower than 20°F) and frost protection (temperatures lower than 34°F)
for the blooms the following spring. If the winter season temperature is average to below
average, I would apply a medium weight row cover (1 oz/yd2) in late December and keep it on
the plants until they begin sprouting new leaves from the crown in February. Taking the row
covers off at the beginning of leaf growth will slow the plants down so they don’t flower too
early. Flowering should commence in early to mid March on ‘Chandler’ within a high tunnel in
Missouri in order to begin harvesting in early April. Remember, strawberries are a cool season
crop, and the high tunnels should be kept relatively cool during the winter. Therefore, some
venting may be necessary during mild winter days. If temperatures get too warm within the high
tunnel, the strawberries may flower too early resulting in lost yield.
When the ‘Chandler’ strawberries are beginning to go into dormancy in late December, they
should have approximately 8 leaves per plant.
E. Pollination and Fruit Set
The ‘Chandler’ strawberries began to bloom in mid-March in Columbia, MO. At that time, the
vents were closed most days, and many natural pollinators could not enter the high tunnel.
Strawberries will set fruit without pollinators, but maximum berry size and weight are obtained
by having good cross pollination of flowers with bees (Figure 6A).

5. A B
Figure 6. A. Effective pollination of strawberries is essential for maximum yield. B. A NUC box used for
honeybees within a high tunnel (Courtesy: Jann Amos).
Different pollinators for high tunnel strawberries were evaluated in 2006 using honeybees,
bumblebees and natural pollinators (flies, solitary bees, wasps and native bumblebees). For
honeybees, a small NUC colony that was placed in one of the high tunnels (Figure 6B). An
entry/exit hole was made so the bees could freely exit the high tunnel from the 3-frame NUC
box. A Class C “mini hive” of bumblebees containing about 200 bees was used to evaluate
bumblebee pollination (Hydro-Gardens Inc.). Class C hives will last about 5 weeks. One high
tunnel was used to evaluate natural pollinators. Any pollinator which entered the high tunnel
from the outside was considered a natural pollinator.
Honeybees were the most effective pollinators as measured by a significant increase in
marketable berry weight, but the bumblebees were close behind (Figure 7). There was no
difference in earliness with either bee treatment, although the naturally-pollinated high tunnel
was harvested one week later. Generally speaking, honeybees were easy to manage within the
high tunnel. They seemed disoriented at times, but were not a management problem. However,
if the high tunnel is used for strawberries and other vegetables concurrently, the bees may
interfere with planting and other activities. Honeybees will seldom fly at temperatures less than
55°F. Fortunately during March, the high tunnels are warm and the bees are active. Bumblebees
are active in cooler weather and are more controlled in their flying behavior within a high tunnel.
They are very efficient pollinators working the flowers until dark. However, since there are
fewer bumblebees relative to honeybees, they must be prevented from leaving the high tunnel
through vents and other openings. Insect screening can be placed over the sidewalls to prevent
the bumblebees from escaping the high tunnel. Insect screening will also prevent aphids and
mites from colonizing most high tunnel crops.

6. F. Pest Management
One of the most serious diseases of high tunnel strawberries is Botrytis gray mold. Gray mold is
severe in cloudy, cool, humid conditions. Gray mold is a fluffy fungal growth on the fruit or
flower stalks making the fruit unmarketable (Figure 8A). Avoid high humidity within the high
tunnel. Excessive foliage from too much nitrogen fertilization can also trigger gray mold
problems. Beginning at flowering the blooms can be sprayed with a fungicide such as Topsin®,
Captan®, Thiram® or Pristine®.
A B
Figure 8. Botrytis gray mold (A) and spider mites (B) on strawberries can be a problem in high tunnels.
Aphids can develop within the high tunnel especially if the plants are over fertilized with
nitrogen. Spider mites will often develop as a problem in May. Damage from spider mites looks
a lot like a nitrogen deficiency (yellowing of leaves)(Figure 8B). Predatory mites can be used to
control spider mites if they are detected early enough. Otherwise, there are several registered
miticides which will effectively control this pest. Consult the Midwest Small Fruit Management
Handbook for more information on pests affecting strawberries.
G. Harvest
Most strawberries were harvested starting 28 days after flowering. Harvest commenced on April
12, 2006 which is at least 4 weeks earlier than field-grown, matted row strawberries and 2 weeks
earlier than plasticulture, open-field ‘Chandler’ strawberries. Over 95% of high tunnel picked
berries were marketable, relative to only 60% for an open field plot of ‘Chandler’ berries. Size
and quality were excellent with most berries averaging approximately 12% sugars. ‘Chandler’
berries are firm with good shelf life. The berries were harvested in pulp, quart baskets and test
marketed in early May at three wholesale produce auctions in Missouri (Figure 9). Prices ranged
from $2.75- $6.00/quart with an average price of $4.40 per quart ($3.67/lb.). As supplies of local
berries increased, the price expectedly declined significantly. However, high tunnel strawberries
peaked in yield before local supplies became significant. Harvest continued until June 10, 2006.
In late May, a shade cloth was placed on the high tunnels to lower temperature within the high
tunnel.

7. The use of a shade cloth seemed to improve fruit quality as temperatures increased.
Average marketable yield across all high tunnels was 1.2 lbs (1 quart) of berries per plant. In
order for high tunnel strawberries to be profitable, each plant must yield at least 1 pound of
marketable fruit. High tunnels seem to offer potential for Missouri growers to expand their
production and marketing season for strawberries.

8. High tunnel strawberries are ready for market in early April when local berry supplies are low
and imported berries have inferior taste and appearance. The break even price for high tunnel
strawberries was calculated to be $1.28/lb or $1.53 per quart assuming an average yield of 1 lb
per plant. Most growers should expect a retail price of at least $3.00/lb or $3.60 per quart.
Wholesale prices should exceed $2.50/lb or $3.00/quart (Table 2). After the strawberries are
harvested in mid June, they can be followed by such crops as tomatoes, peppers, melons,
cucumbers or squash.
