And yet, horticulture is a very important facet of the food we consume daily. Horticulture, however, embraces much more than just food crops. Although horticultural practices go on all year, we are according to many people just at the beginning of the gardening season. Gardening to some means planting flowers and to others it means planting a vegetable garden. Take, for example, the fact that countless business men and women have found gardening in some form is a wonderful way to diffuse the pressures encountered in the business world. Just tinkering with a few potted plants may be just as effective as planting a big flower bed or vegetable garden.

In a garden there are certain operations that are to be followed judiciously for successful cultivation of flowers and ornamental plants, most of these operations, such as pinching, deshooting , disbudding, desuckering etc , are of vital importance for the growth of the plants.

These operations are generally known as special horticultural practices. The operation of pinching or stopping involves the removal of the growing-point of a shoot along with a few leaves. The m ain purposes of pinching are To increase the production of flower-buds on the branch which is pinched. Pinching is done at a stage when the plants are young and between 7 and 15 cm in height, depending on their habits of growth.

The plants which need pinching include dahlia, chrysanthemum, marigold, carnation, rose. First pinching is done when the plants reach a height of cm with pairs of leaves. A second pinching may be necessary if the plants make straggly and lean growth. In soft pinching the soft tip of the shoot along with open leaves is removed while in hard pinching a longer portion up to hard shoot is removed.

In case of standard chrysanthemum only single bloom on a branch is usually allowed to produce. The pinching is not done if only one central bloom is desired on the main branch. Single pinching is done, if two flowers are desired, whereas double pinching is done for four flowers. In spray chrysanthemum numerous small to medium sized flowers are produced, therefore, two pinching are required to encourage lateral growth.

As a general rule rooted cuttings are pinched 2 weeks after planting or approximately days before full bloom. Pinching in rose is generally practiced to adjust flowering for a particular season. An examination of the rose stem will show that below a flower bud there is strap shaped leaf followed by 3 leaflet and 5 leaflet leaves, in the axils of which there are a reasonably long stem, pinching has to be done above a 5 leaflet leaf with a rounded bud.

The shoots selected for later flower production, are pinched by removing cm of terminal growth, after at least 15 cm growth is formed. This procedure of pinching prevents flowering and encourages the plants to form new growth the base.

Single pinch is done once at 5 node stage by retaining shoots for obtaining early crops. Second type of pinching is pinch and a half. In this type of pinch, the main stem is pinched and later when the resulting shoots are long enough, half of largest shoots on each plants is pinched.

Double pinching is done in carnation, first by doing single pinch followed by another pinching of all the shoots when they are cm in length. Marigold plants grow straight upward to their final height and develop into terminal flower buds. After production of terminal flower bud, side buds become free from correlative inhibition of apical dominance and these buds develop into branches to produce flowers. If the terminal portion of shoots is removed early, that is 40 days after transplanting, emergence of side branches starts earlier and more number of flowers of good quality and uniform size are produced.

Some flowering annuals and herbaceous perennials produce numerous side shoots and if all of them are allowed to lower, the size and quality of the flowers will be greatly reduced. Only a specific number of side shoots are allowed to flower and the others are removed at an early stage.

Deshooting is practiced from time to time by removing all side shoots before they attain the size of 2. Removal of all secondary shoots from 5 week after planting and on alternate days till flowering does not affect the stem lengths but stem size and flower size is increased by per plant. To produce large specimen bloom, the flower buds per stem must be restricted to one.

For this, the central or crown bud is retained and the buds or side shoots clustered around the central bud are removed. In many plants several superfluous bud, flowers, and shoots develop in the axils of the main stems and branches.

Many of the varieties are disbud or standard types, in which the largest terminal bud is retained and all axillary buds are removed. Disbudding of spray varieties is very easy because in this case only the large apical bud is removed and the axillary buds are allowed to develop.

The disbudding must be done regularly and also as soon as possible in order to avoid large wounds in the upper leaf axil. In hybrid Tea roses only one or at best two buds should be allowed to flower upon each shoot so as to have a large sized bloom.

In standard carnations, side buds should be removed whereas in spray carnations, the terminal bud has to be removed. Dahlia will generally have three flower buds at the end of each branch.

If the crown bud is damaged, one side bud has to be retained in place of the central bud. During the vegetative growth phase, plant grows upward and new suckers continue to develop from the base of the plants.

For preventing improper and vigorous growth of plant, suckers are removed from time to time. This can also be done to reduce transpiration loss during periods of stress and strain and also during transportation of certain plants such as roses.

Defoliation can be achieved by the removal of leaves by hand or by the use chemical and withholding water. Various chemical defoliants reduced the apical dominance and encouraged lateral shoots. Pentachlorophenol and sodium chloride sprays increased flower yield than un pruned plants of Jasminum grandiflorum.

Application of ppm of pentachlorophenol was found more effective in flower production in Jasminum grandiflorum. This may be considered as an alternative to root pruning. In the hotter parts of India it may not be wise to resort to root pruning. Flowering shrubs such as rose and jasmine can be wintered in northern and eastern India. During resting period the water supply to the plant to be wintered is stopped for a few days and the roots are exposed to the sun by removing the surface soil around the trunk.

The duration of exposure varies from three to fifteen days depending upon the age, the nature, and the hardiness of the plant. After this the roots are covered with the same soil enriched with farm yard manure and copiously watered. Leaf is a source of food for every plant. There should be balance between Source Assimilation and sink Dissimilation.

These sprouts will grow as branches and these branches in turn form buds. The first bottom break or ground shoot will start coming from the base. These ground shoots form the basic framework for production and there on the ground shoots should be cut at 5th five pair of leaves and medium ground shoots should be cut at 2nd or 3rd five pair of leaves. Plants in the garden, either in pots or on ground, need support at least for a parts of, or throughout, its life. Selecting the proper stakes and fixing them aesthetically as well as purposefully is an art.

The most common stakes used in India are made of either whole bamboo or split bamboo of various sizes depending upon the type of plants to be stakes. Metallic wire is tied around the bed along the length with the support from supporting poles. For an optimum support, an increasing width of the meshes can be used. Bottom net can be of 10x10cm, then two nets ofEspecially large flowers varieties of gladiolus grown outdoor are susceptible to lodging, hence need staking.

Earthing up of the plants, when the spike starts elongation, also provides sufficient to prevent lodging. The plants should be tied loosely around the stem to allow further growth of plants. The lateral are staked with strong split bamboo stakes inserted in the compost with a view to given support and also see that these are spread out from each other.

The first crown bud develops at the end of each lateral which contains maximum number of ray florets and will be give the largest bloom, though may not be the best bloom.

The intention is to regulate soil temperature, to conserve moisture, and to control weed. There are several kinds of mulch such as straw, leaves, pulverized corn cobs, peanut hulls, cottonseed hulls, stable manure. Mulching helps to maintain an even soil temperature, induces early flowering and better blooms.

The main disadvantage is that, it serves as a home for various insect and pests. Pruning: - The planned removal of branches, twigs, limbs, shoot, or root is termed as pruning.

Root pruning is done to a limited extent in ornamental horticulture, as in the case of rose and jasmine. The main effects of root pruning are 1 reduced absorption, 2 reduced top growth, and 3 more branching in the root system. Pruning is an important cultural practice in jasmine, which encourages growth of new healthy shoots and influences the flower yield. In large plantations, pruning is done on different dates to get the harvest in well-spaced manner as otherwise all plants will start flowering at a time.

However, in Jasminum grandiflorum, December pruning is beneficial as maximum yield is obtained if the plants are pruned in this month ,and first picking could be done in March.

But all pruning dates in January and February delay the picking till May to June. Jasminum auriculatum can be pruned during January to March to have flowers for longer duration, while Jasminum pubescence should be prune as soon as they finish flowering in early summer. In Jasminum sambac pruning after normal flowering season stimulates another flush of flowers. Time of pruning:- In most parts of India, pruning is done during October. Pruning in Hybrid Tea roses - end of first week of October.

Pruning in Floribundas - In the first season, pruning will be similar to that of hybrid Tea rose to encourage more growth from the base. Pruning of standard roses - The pruning of standard roses is somewhat similar to that of bush rose. The aim should be to have a well-shaped plant with the crown growing symmetrically in all direction. Forcing lily flower for normal durations, the bulbs require cold treatment at 0 C for 6 weeks in case of Asiatic hybrids and 8 weeks for the Oriental ones.

It is possible to use "frozen-in" bulbs which are kept at 1 0 C after pre-cooling treatment for off-season flowering. A night temperature of 16 0 C with a day temperature below 21 0 C inside the greenhouse is recommended for forcing. Singh, A. Flower Crops Cultivation and Management. Randhawa, G.

Of the more than 1, species including poinsettia, castor bean and cassava , crown of thorns, E. Many cultivars and hybrids have been developed that vary in flower size and color. The species name milii honors Baron Milius, once governor of the island of Bourbon, who introduced the species into cultivation in France inThe common name refers to a legend that this plant was used as the thorny crown worn by Jesus at his crucifixion. There is evidence that this plant had been brought to the Middle East before the time of Christ and the stems are flexible enough to weave into a circle, but it is more likely that another plant was used as his crown.

Youth who grew up in the Taurus Mountains of Turkey have traditionally moved to the big cities to pursue their careers. It might seem counter-intuitive to suggest that agriculture should become more nutrition-sensitive — but many small-scale producers worldwide are at risk of food and nutrition insecurity. Ending extreme poverty and hunger will be difficult without more investment and more innovative approaches. Nowhere is the challenge of leaving no one behind more salient than in rural areas. The outbreak of COVID has rapidly spread across the world, profoundly disrupting the fundamental activities that bring the global community together, including agriculture — and endangering all those who depend on it as their livelihood. A food system includes all the aspects of feeding and nourishing people: growing, harvesting, packaging, processing, transporting, marketing and consuming food.

UAN application image source. Surface broadcast is a method by which fertilizer is applied on the surface across an entire field. High capacity fertilizer spreaders are often used which spin dry fertilizer or spray liquid fertilizer on the soil surface or on a growing crop. Broadcast incorporated improves on the efficiency of surface application by incorporating fertilizer through plowing or disking. Plowing is considered better in terms of nutrient availability, as it creates a nutrient-rich zone a few inches below soil surface where developing plant roots can absorb it.

This article covers these and some other crucial issues related to the topic. Monoculture farming is a form of agriculture that is based on growing only one type of a crop at one time on a specific field.

Agriculture Specialist

Horticulture is the art of cultivating plants in gardens to produce food and medicinal ingredients, or for comfort and ornamental purposes. Horticulturists are agriculturists who grow flowers, fruits and nuts, vegetables and herbs, as well as ornamental trees and lawns. The study and practice of horticulture have been traced back thousands of years. Horticulture contributed to the transition from nomadic human communities to sedentary, or semi-sedentary, horticultural communities. In order to conserve the science of horticulture, multiple organizations worldwide educate, encourage, and promote the advancement of horticulture.
