BOTANICAL DESCRIPTION OF ROSES
•Rose belongs to family Rosaceae.
•All species of this flower with minor exception belongs to the genus Rosa.
•There are about 150 recognized and described species of roses.
•The genus Rosa is divided into 4 sub genera namely- Eurosa, Platyrhodon,Hesperhodos, Hulthemia.




Floribunda:- (Hybrid tea x Poliantha)
•They combined the beautiful forms of the Hybrid Teas with the perpetual flowering habit of the Polyanthas.
•Flowering in clusters with small size and open centre.
•Good for garden display.
•Important Desi Variety is ARKA SAVI

CLIMATE
•The temperature should be maintained between 10-42⁰ C.
•Savi can sustain hard climatic conditions as well where is sun loving open field variety.

SOIL:
•An ideal soil should be rich loose and structurally stable with a depth of
•around 50cm ensuring optimum drainage and aeration of the roots.
•Roses do not tolerate water logging and high water table therefore an ideal soil must have a stable water table at the active root zone.
•Roses can also be grown in soil less media like rock wool, peat, cocopeat,
•perlite.
•Soil pH should be slightly acidic 6.2-6.8.

Land Preparation
•The soil should be dug to a depth of 60 cm. and incorporated with organic or inorganic additives to improve the soil structure.
•Soil sterilizing is an important technique to prevent the soil from soil borne diseases.
•Recommended for chemical poured lands earlier should do plantation of beans or navadanyas during flowering stage plough the same to increase microbial activities by the live mulch.

Manure and Fertilizers
•Roses are gross feeder.
•The requirement of major nutrient are broadcasted on the beds and mixed into the upper 30 cm of soil.
•After establishment of plant nutrition is applied through irrigation system.

CONCENTRATED REQUIRED FOR FERTIGATION ( These Manure and fertilizers covered in SAVI cultivation Whitepaper)


PLANTING
1.Ideal method of planting of rose double row system.
2.Plant to plant distance -1 Mtr.
3.Row to row distance-6 Feet .
4.Planting time: Except Summer.


Plant growth regulators
Gibberellic Acid:- Gibberellic acid is found at a high concentration in the developing seed of a peach. Other plant sources include onion bulbs, spinach and ferns. Overall, 136 different naturally occurring gibberellic acid compounds have been isolated in plants, fungi and bacteria. With Mulch we can achieve this
•Regulate the growth and flowering
•Increases the length of shoots
•Increases the number of nodes
•Prolonged the period of flowering and enhanced the yield.
•Waste Decomposer mixed solution caused dwarfing and improve flowering.

Irrigation
•Roses do not like water logging condition but need plenty of water for their growth and development.
•Frequency of irrigation depends on the water requirement of particular varieties.
•Ideal method-Drip irrigation system
•Another method of irrigation –Sub surface ,in which water is directly delivered at the root zone without any losses.
•Regular soil moisture is very essential for rose.

Manual weed control is effective if done frequently.
Rice straw mulch is also effective.
Major weeds of rose :- Anagallis arvensis, Melilotus albums. Chinopodium alba,

Mulching
•It conserve soil moisture.
•Supply humus.
•Suppress weeds.
•It is done with paddy straw, dried leaves.
•Also promotes growth and flowering.
•It promotes physical properties of the soil.

Pest Management
•Alphids : Remove aphids by hand by spraying water or knocking them into a bucket of soapy water. Control with natural or organic sprays like Wastedecomposer with Soapnuts or shikai , neem oil, or essential oils. Employ natural predators like ladybugs, green lacewings, and birds.
•Thrips : Foliar application of neem seed kernel extract or biodynamic liquid pesticides prepared with herbal plant extract will mange the thrips and other insect in organic farming. This spray at initial stage is more effective than at serious stage .
•Our regular Foliar management will address thrips . and Custard apple seeds oil sprays will downgrade any pest issues.
•Mites : Foliar application of neem seed kernel extract or biodynamic liquid pesticides prepared with herbal plant extract will mange the thrips and other insect in organic farming. This spray at initial stage is more effective than at serious stage .
•Our regular Foliar management will address thrips . and Dasaparni ARK which is prepared by WDC is recommended.
•White Fly: Foliar application of neem seed kernel extract or biodynamic liquid pesticides prepared with herbal plant extract will mange the thrips and other insect in organic farming. This spray at initial stage is more effective than at serious stage .
•Our regular Foliar management will address thrips . and Dasaparni ARK which is prepared by WDC is recommended.

Disease management
Leaf spot : Black Spot of Rose. Black spot is caused by the fungus, Diplocarpon rosae. It is one of the most common diseases found everywhere roses are planted. The disease does not kill the plant outright, but over time, the loss of leaves can weaken the plant making it more susceptible to other stresses and winter damage. As the root cause is fungus we can manage the fungus as we are using regular intervals WDC , Jeevamruth and additional to this sour butter milk can be applied .

Powdery mildew:Rose powdery mildew is a disease of roses caused by the fungus Sphaerotheca pannosa var. rosae. It forms what looks like a white powder over the surface area of the rose leaves and may also spread to the stems and new rose buds.As the root cause is fungus we can manage the fungus as we are using regular intervals WDC , Jeevamruth and additional to this sour butter milk.
Downey mildew:On roses, downy mildew occurs on all above-ground plant parts, blighting the leaves and canes. Sometimes the first symptoms of downy mildew are confused with a nutrient deficiency or spray injury. Infected leaves turn yellow and drop from the plant. A downy mildew infection may leave the plant nearly devoid of foliage. Foliar application can control Downey mildew too.
Botrytis blight : Botrytis Blight of Roses. Botrytis blight is a fungal disease found worldwide that infects a wide range of plants, creating devastating losses for ornamental plant and vegetable growers. On roses, the fungus botrytis cinerea causes the disease also known as gray mold. As the root cause is fungus we can manage the fungus as we are using regular intervals WDC , Jeevamruth and additional to this sour butter milk.
Crown gall : Use of disease - free planting material and destruction of infected material .
Crown Gall of Rose. Crown Gall, a disease caused by a soil borne bacterium, can severely damage rose plants. Galls begin as small swellings, usually at ground level, that slowly increase in size. Infected rose plants become stunted and very often die.

Die-back :copper fungicides to cut ends immediately after pruning. Immediately have to place cow dung for better protection and avoid dry back where as since the ages we are following this practices after pruning placing cowdung and its works well too. Rose dieback is a condition commonly affecting rose plants where there is browning or blackening of the tip of the rose stem or a branch which then travels down toward the graft and may engulf the whole plant causing death. It can either be a Branch die back or the main stem dieback towards the graft.
Blind shoots:
× No flower bud initiation .
× Shoots do not initiates of pistils and stamens primordial.
Causes :
× Low temperature.
× Boron deficiency.

Harvesting and yield:
Harvesting of flowers should be done either in the morning or evening hours. Stage of harvest varies with the variety and distance to the market. Loose flowers are harvested at the initiation of flower opening. Arka Savi - 30 tonnes per acre per year

Dhabolkar method of green manuring

Mr.Dhabolkar, an organic farming expert in Maharashtra, has proved the efficacy of green manure method, which helps to return to the soil many times more nutrients than what we take from that same soil. The first step, therefore, to enrich the soil organically is to grow a variety of crops on the land and then plough the green matter back into the soil. Using this method it is possible to enrich the depleted soil in just two hundred days. Even land that has been depleted of all nutrients due to chemical farming can be resuscitated in this manner.By growing the following crops for 50-60 days and then ploughing them in-situ we add balanced nutrients and micro-nutrients to the land. The soil will become enriched in less than a year and micro-nutrient deficiency is eliminated.

The following quantities will suffice for one acre.
Choose four of each of the following types:(One from category total five)

1. Grains: 5Kg (Example: 1 kg Sorghum, 500 gms Pearl millet, 250 gms Foxtail millet, 250 gms …

Navadhanya Cropping System

NAVADHANYA has not introduced by anybody from his/her own experiences and knowledge. It has evolved, by following the climatic conditions; district farmers were cultivated dryland agriculture in the district. With the erratic rainfall every year the farmers are facing drought in the district. Even though in erratic rainfall also the dry land agriculture is sustained in the district during the past. With experiences in their life, the cropping system was evolved as NAVADHANYA a dryland agriculture system in the district. The NAVA DHANYA is an intercropping system in dryland agriculture. It has evolved to sustain crops in erratic rainfall by the farmer’s experiments. And also, it has evolved the system for trapping erratic rainfall and utilizing 100% to the crops. So, the farmers used the system as net of erratic rainfall in drought-prone areas for protecting at least 2/3 of the crops in their fields. The cropping system will keep the land greenery for 10 months in a year. So, the syste…
