Protected Cultivation|Green House Cultivation of Rose

Rose is called the king of flowers, the most beautiful creation of nature, the world’s most known and famous cut flower. Roses are at the forefront of the world’s flower industry has sales of approximately 1.8 billion dollars. The market for Roses in Holland alone is approximately 500 million USD, which is growing at a rate of 7-8 percent annually. Colombia, Kenya and other African countries account for 30 percent of the total rose production in the world.

In cold zone countries, the temperature in winter goes below zero, artificially greenhouses have to be heated at 26° – 28° C.G. to maintain temperature and light relatively more expensive.

India’s contribution is not significant in rose production. Now the importance of the flower industry in our country has increased since the last decade, so India has many opportunities to export Roses and earns foreign currency.

If, we want to grow Roses for foreign markets like Europe, Japan, and America, those countries’ popular varieties and high-quality standards such as

  • BUD SIZE,
  • STEM LENGTH,
  • GREEN GLOSSY LEAVES,
  • DISEASE AND PEST-FREE FLOWERS have to be kept in mind.

Points to keep in mind for variety selection:

  • High-yielding varieties should be grown.
  • Varieties with more durable flower power should be chosen.
  • Flowers can store more water.
  • Thornless varieties that are easy to groom.
  • Red color is very popular among varieties with good color. But pink, orange, bicolor, and non-fading varieties are also popular.
  • Medium aromatic.
  • Varieties resistant to diseases, pests, and other physical conditions or deterioration in harvesting or transport.

FIVE Different types of Roses Grown in Greenhouses and Varieties:

THERE ARE FIVE DIFFERENT TYPES OF ROSES

  • Long-stem Roses: Hybrid-T with large flowers
  • Medium-length stems: Floribunda, medium-sized flowers

1.Long Stem Rose (Hybrid-T):

  • Generally, the stems of these flowers are 50-120 cm long and production is 100 to 150 flowers/sq. m/year. Flowers are harvested 40-60 days after planting. These flowers require a lot of care. The vase life of these flowers is shorter than Floribunda flowers.

2.Medium-stem Roses (Floribunda):

  • Generally in Holland, the stem length of these flowers is kept 50-70 cm. The production of these flowers is 200 flowers/sq.m/year. Here the size of the flower is big. These flowers are widely grown in Kenya.

3.Short Stem Flowers (Sweet Heart):

  • The stem length of these flowers is seen up to 30-70 cm in the market. The production of these flowers is 250-350 flowers/sq.m./year. It takes a lot of time to harvest these types of flowers.

4.Spray-type Roses:

  • This type of rose has flowers in clusters on a stem. Generally, these flowers have low production and the stems weigh more. So the cost of sending by plane to other countries becomes expensive.

5.Miniature Roses:

  • The stem length of this type of flower is 20-50 cm. The size of this rose is much smaller than other Roses. Generally, these types of Roses have become popular for planting in pots. The production of this type of flower is 500 flowers/sq. m/year. But harvesting these flowers takes a lot of time.

Varieties of Roses Grown in Greenhouses:

Long Stem (Hybrid Tea) Rose Varieties Grown in Indian Greenhouses:

Flower color varieties:

  • Red Top Secret, Samurai, Passion, Lovely Red, First Red, Grand Gala
  • White Avalanche, Tinke, Masai
  • Pink Poison, Pretty Gal, Noblesse, Shakira, Vivaldi
  • Orange Naranga, Candied Profita,
  • Yellow Gold Strike, Papillon, Yellow Unique, Alsmeer Gold, Confetti, Yellow Success

Climate:

  • A greenhouse should have enough light throughout the year along with temperatures ranging from 18° to 28°C. If the temperature is above 28°C, the relative humidity should be increased, so that water can be prevented from flying off the surface of the plant. There should not be more than 15°C to 18°C night temperature and 30°C during day time in the greenhouse.
  • During the winter period, additional light is very beneficial for cut flower production. It is very important to maintain the ratio of light and temperature. Vegetative growth, cut flower production and flower quality of rose plants in greenhouses can be enhanced by additional carbon dioxide (up to 1000 ppm). Excessive temperature and humidity can lead to blistering. Day length of less than twelve hours and cloudy weather are detrimental to plant growth.

Land and Preparation:

  • To grow Roses in a greenhouse, proper size bed should be made and afterward sown the rose plant. Roses require a medium with a very good drainage facility.  Loamy, well-drained, loamy soil with PH 5.5 is suitable for rose farming. If the water table is high, make a cushion bed 25-30 cm long and sow the plant.
  • The length of the row depends on the size of the greenhouse. Usually 90 cm wide and 30-40 meters long can be made. Distance between rows should be maintained at 14 to 18 cm. Generally, the plant density of Roses in greenhouses is kept at 60,000 to 70,000 plants per hectare.

Method of Planting:

  • Generally healthy and disease-free eye-grafted seedlings are used. Plant out small plants in April-May and large plants in August-September, so that the first cutting is available during CHRISTMAS and then the second cutting during VALENTINE’S DAY. Young plants of 6-18 months are considered suitable for planting. Dig a suitable size pit, so the roots of the plant best fit in the soil, press the soil around it and water it. Planting should be done in such a way that the grafted part of the plant is above the ground while planting.

Special Care:

  • After planting, keep the greenhouse warm and humid, so that it can grow quickly. Spraying water on young plants during periods of heavy sunlight, so that mortality rate can be reduced. After four weeks, in the eye-grafted plant, a flower bud (like a pea) will appear which should be broken off so that the plant can grow well.

Building Infrastructure:

  • Establishing a strong plant structure is very important for the production of good-quality flowers.

Resting the plant:

  • Stop fertilizing and watering after the last flower is harvested in June-August. Rest for 4 to 8 weeks depending on the type of soil. Most of the leaves will fall off. Prune plant 30-60 cm above the ground. After that, watering and fertilizing should be done.

Daily Work in Greenhouse:

  • Supporting the plants: Planting supports at a distance of 3 meters on both sides of the bed with 30-40 cm above it. Support the plant with galvanized wire or plastic rope at a distance of
  •  Picking off extra buds (Disbudding): Breaking the extra buds below the main bud, so as to increase the size and quality of the main flower.
  •  Level the land with additional land if the land of the cushion bed has come up on the road.

Bending Method:

  • The bending process is very important when growing Roses in the greenhouse. The leaves on the rose plant produce carbohydrates and these leaves are called the lungs of the plant. Here you have to bend (bend) the eyeless stalks from bottom to top by 5 cm and take special care that the stem of the plant does not break at that time. So first bend the stem of the plant at an angle of 450 and then 900. By doing this, the growth of the eyeless stem is stopped and the food in it reaches the other budded stem.

Pruning of flowers:

  • The pruning stage of rose flowers is determined by variety. Harvesting is determined by market demand and its distance from the farm or export market. After harvest, the rose should be in full bloom when it reaches the consumer. If the flower bud is cut at the wrong position, it will not open properly in the vase.
  • One to two ripe leaves should remain on the plant at the time of harvest. Flowers should be removed early in the morning. Flowering should be done when the petals have fully colored and the outer one or two petals have started to unfold (tight bud stage). The number of whorls varies with temperature and species.

Crop Protection:

MITE:

  • Pests like Aphids, Jassid, and Thrips are found in abundance. Damage from this type of pest can be seen on the plant with wilting, bitten leaves or yellowing leaves. Such pests can be controlled by repellents like Fipronil 10 ml/10 litres, Imidacloprid 8 ml/10 liters of water.
  • For effective control of mites use Abamectin 1.9% EC drug 5 ml/10 liters or Dicofol 18.5% EC 25 ml/10 liters. For control of Budworm use Emamectin Benzoate 5% soluble granules 3 gm or Diflubenzuron 25% WP 16 g/10 liters.

Disease:

  • Powdery Mildew:- Wettable Sulfur 20 gms/10 liters
  • Black spot disease:- Propiconazole 10 ml/10 liters of water should be sprayed.

Maintenance after flowering:

  • The flowers should be placed in a bucket full of water immediately after plucking. Then keep it in cold storage at 2°C to 10°C for three hours. Classification of rose follower is done according to the length and quality of the stem. Stems should be free from pests, free from soil or drug residues, and free from spots. The size of the bud and the thickness of the stem should be the same. So quality and good looks can get good prices.

Grading:

  • Grading of flowers is done in a cold storage room before packing. Rose flowers are graded based on stem length and flower color.

Packing:

  • Roses are packed in Corrugated Fiber Board (CFB) boxes and cover should be telescopic. These flowers should be arranged in a round bunch and the stem part should be wrapped with moist paper and the upper bud part should be covered with tissue paper.
  • Polyethylene sheet should be spread in the bottom part of this box and tissue paper should be placed on the sides. Placing tissue paper does not cause friction to the flowers. A tissue paper should be placed between the two layers forming a bunch. So that the flowers cannot touch each other. Separate the flowers according to the length of the stem and make bundles (20 flowers) and wrap them in corrugated paper. Four pairs of flowers (80 stems) are arranged in a box. Flowers should be kept at room temperature.

Steps to keep flowers fresh for longer:

  • To keep rose flowers fresh for a long time, systematic use of sucrose solution (1-3%), 8-HQC (100-200 ppm), and citric acid solution can keep the flowers fresh for a long time.

Yield:

  • Generally, Roses produce 10 to 30 flowers per plant or 150 to 200 flowers per square meter per year. Production is based on breed and fitness.

Conclusion: For better quality and higher yield it is essential to cultivate ROSE plant in the poly house
