Fed on organic farming (RM) 1 rosemary cultivation tips 

Soil and climate 

PH 5.5 to 7 varaikonta laterite soil with good drainage facilities suitable for rosemary. Soil pH of 2.5 tons per hectare when there is less than 5 ittup of talamaittai be planted in the soil. Frost-free tropical and subtropical summer monsoon (temperature less than 30 degrees), the temperature is optimal. At an altitude of 2500 meters above sea level, 900 of the first well in the kulirpirateca areas.Image title

Rosemary J.% of root seedlings - J% Lie and September - the months of October, suitable for rainfed crop planting. 

Perennial crop. Can be grown commercially until twelve years. 

Land preparation 
Panpatutta well be plowed land twice. 50 tons per hectare during the last plowing well-composted manure, neem cake a ton, 5-ton natural life force of compost manure is mixed with soil lead. 30 cm in height, 1.5 meters wide plots. Natumpolutu seedlings per acre and 5 kg 5 kg PSB supplying bio-fertilizers applied to the soil mix. 

Seed size 
50,000 seedlings - ha.

Seedlings from the breeding method 

Before leaving for flowering plants to choose from 10 to 15 cm long pieces of cut. Leaves, leaving only the tip of the stem sticks to the bottom of the planting should be used to remove the remaining leaves. Before planting to enhance rooting of stem sticks herbal natural life force, fertilizer, bio-fertilizer solution containing 10 percent of the 20 minute walk back to thinking. Polythene bags filled with soil mix after the planting of the stem pieces and pour water twice daily to keep in shady areas. Sixty days, the rooted seedlings are ready for planting. 

With the exception of the poly malaippaci budded seedling production 


45 cm row to row and plant cetikkuc vittac root plants should be transplanted in 45 cm intervals. And 6 months after planting, the plant should be cut maiyattantai. By doing so, the plant grows well in the lateral branches.

Water cannon 
Drought tolerance is also suitable for planting in dry land. Green leaf with water in dry periods payccutalin get higher yield. 

Basal FYM 50 t / ha, neem cake @ 1 t / ha, the natural life force Compost 5 t / ha and vermin-compost compost 5 t / ha can be applied as a seedling natumpolutu. Phosphobacterium bio-fertilizers, bio-fertilizers and inoculant and 5 kg per ha as basal dose required. 

Application of bio-fertilizers 
பாஸ்போபாக்டீரியம் and supplying fertilizers, such as from the second year after planting survival rate of 5 kg to 30 kg per hectare should be applied with FYM. The solution of 3 per cent per year, 5 times more pancakavyam telippatin the leaves will increase the quality and yield. 

Post Treatment 
A month later weeding nut boiling mud. 4 or 5 times per year need deadheading. The solution of 3 percent to 5 times a year Panchagavya foliar spray to spray at 10 days interval. Tacakavya 3 percent solution is to spray 3 times per year. Vermi compost 10 percent distilled water solution 3 times per year with a foliar spray to spray on a monthly interval.

Crop Protection
It is resistant to pests and fungal diseases. 

12 to 13 tons per hectare of green leaves 

Rosemary plant leaves can be harvested at flowering stage. 30 to 35 cm in length with the flowering stage over the leaf stems should be harvested with sickles. Hard tanmaiyataiyata well developed trunk areas suitable for oil distillation. If you are using a number of filtering portions of the shaft with the number and complexity of the quality suffers and the mind. Yield in the first 215 days of the year preparing for planting. In the following years, three times per year, respectively, can yield three to four month intervals.

Processing leaves 

The leaves are harvested in the soil and removing the dust should wash three times. Then dried in the shade. Nilgiris dried up in the 10 to 15 days. Exactly equal to the plain areas, such as dried leaves, leaves scene to take concrete floor ventilation caused by the electric fan to keep dry. In the three days, with 10 percent moisture can get good quality leaves. Then the quality of the food to be stored in a Polyethylene bags.

, layers and division of roots.   Commercial propagation is through 10-15 cm cuttings which are planted in the nursery beds and after about 6-8 weeks they can be transplanted in the main field.

Weed control

Pest and disease control
Rosemary is vulnerable to spider mites, mealy bugs,Whiteflies and thrips.  
Late blight disease has been reported which can be controlled by drenching the plant with Maneb (1%) at 8-10 days interval.

The first harvest of leaves begins from 8 months after planting, and subsequent harvests can be done at an interval of 3 to 4 months. Annually three to four harvests can be had, and this perennial crop can be retained for upto twelve years, based on the vigour of the crops. 
Harvest will commence at the time of 50% blooming and continues till 75-90 % inflorescence emergence and must end when the flowers have finished blooming.

On an average, about 12-15t/ha/annum of herbage and an oil yield of about 85 to 100 kg/ha/annum can be obtained.
