Weeds compete with plants for food, space and other essentials. So timely control of weeds is necessary. For weed control weeding, use of cover crops, mulching, use of chemicals weedicides are practiced. Pre-emergence weedicides like Basaline or post-emergence weedicide like 2; 4-D and Roundup are useful. The younger seedling is susceptible to strong sun and low temperature.
For protection from strong sun, shading with the help of timber framework of 1 meter height may be used. Net house and green house structures can also be used. Packing is the method or way in which the young plants are tied or kept together till they are transplanted. So they have to be packed in such a way that they do not lose their turgidity and are able to establish themselves on the new site. At the same time, good packing ensures their success on transplanting. For packing baskets, wooden boxes, plastic bags are used.
In some parts of the country banana leaves are also used for packing the plants with their earth ball. This is useful for local transportation. In general the main demand for nursery plants is during rainy season. A proper strategy should be followed for sale of nursery plants. For that advertisement in local daily newspapers, posters, hand bills, catalogue and appointment of commission agents can be followed. Care of mother plants is necessary so as to get good quality propagules and scion.
Labeling and records B. Protection from pests and diseases Collection and development of new mother plants Fruit Nurseries. We can propagate plants by sexual or by asexual means. Both the methods have certain advantages and disadvantages. So we must select proper method according to our needs and situation. Seed propagation is the simple way of multiplying plants but for plants which do not set fertile seeds we must practice vegetative types of propagation.
Layering, grafting, budding and tissue culture. For propagation, medium is an essential factor. We should use proper medium for particular method of propagation and for particular plant. In this lesson we have also studied the nursery and its management. Growing seedlings under proper supervision and care is the prime objective of the nursery. For this we must follow the nursery techniques. State the prime reasons for asexual propagation.

The Relative Moisture Content of stock lifted during dry conditions can be increased gradually when stored in appropriate conditions. During the growing season, g increased to about 0. Minimum xylem pressure potential PSIm was initially During the first half of the growing season, PSIm was below turgor loss point. The osmotic potential at turgor loss point decreased after planting to In the greenhouse, minimum values of PSIT were Available turgor TA , defined as the integral of turgor over the range of RWC between PSIb and xylem pressure potential at the turgor loss point was 4.
The stomata of both white and black spruce were more sensitive to atmospheric evaporative demands and plant moisture stress during the first growing season after outplanting on 2 boreal sites in northern Ontario than were jack pine stomata,  physiological differences that favoured growth and establishment being more in jack pine than in the spruces. With black spruce and jack pine, but not with white spruce, Grossnickle and Blake's  findings warrant mention in relation to the bareroot-containerized debate.

During the first growing season after outplanting, containerized seedlings of both species had greater needle conductance than bareroot seedlings over a range of absolute humidity deficits. Needle conductance of containerized seedlings of both species remained high during periods of high absolute humidity deficits and increasing plant moisture stress. Bareroot outplants of both species had a greater early season resistance to water-flow through the soil—plant—atmosphere continuum SPAC than had containerized outplants.
Resistance to water flow through the SPAC decreased in bareroot stock of both species as the season progressed, and was comparable to containerized seedlings 9 to 14 weeks after planting. Bareroot black spruce had greater new-root development than containerized stock throughout the growing season. The greater efficiency of water use in newly transplanted 3-year-old white spruce seedlings under low levels of absolute humidity difference in water-stressed plants immediately after planting  helps explain the commonly observed favourable response of young outplants to the nursing effect of a partial canopy.
Silvicultural treatments promoting higher humidity levels at the planting microsite should improve white spruce seedling photosynthesis immediately after planting. Planting stock is grown under many diverse nursery culture regimes, in facilities ranging from sophisticated computerized greenhouses to open compounds.
Types of stock include bareroot seedlings and transplants, and various kinds of containerized stock. For simplicity, both container-grown and bareroot stock are generally referred to as seedlings, and transplants are nursery stock that have been lifted and transplanted into another nursery bed, usually at wider spacing. The size and physiological character of stock vary with the length of growing period and with growing conditions. Until the technology of raising containerized nursery stock bourgeoned in the second half of the twentieth- century, bareroot planting stock classified by its age in years was the norm.
The number of years spent in the nursery seedbed by any particular lot of planting stock is indicated by the 1st of a series of numbers. The 2nd number indicates the years subsequently spent in the transplant line, and a zero is shown if indeed there has been no transplanting. A 3rd number, if any, would indicate the years subsequently spent after a second lifting and transplanting. The numbers are sometimes separated by dashes, but separation by plus sign is more logical inasmuch as the sum of the individual numbers gives the age of the planting stock.
Plant nursery - Wikipedia
The class of planting stock to use on a particular site is generally selected on the basis of historical record of survival, growth, and total cost of surviving trees. Because age alone is an inadequate descriptor of planting stock, various codes have been developed to describe such components of stock characteristics as height, stem diameter, and shoot: Neither age classification nor seedling description code indicate the physiological condition of planting stock, though rigid adherence to a given cultural regime together with observation of performance over a number of years of planting can produce stock suitable for performing on a "same again" basis.
Planting stock is raised under a variety of systems, but these have devolved generally into 2 main groupings: Manuals specifically for the production of bareroot  and containerized  nursery stock are valuable resources for the nursery manager. As well, a lot of good information about nursery stock specific to regional jurisdictions is well presented by Cleary et al. From Wikipedia, the free encyclopedia.
