It grow at pH range of 5.5 to 7.5 is considered as ideal. However, they can also be grown in a pH range of 4.0 -9.0. High calcium carbonate concentration in feeder roots zone directly affect the plant growth.

Flowers of lemon

 

Lemons are wider adoptability and grown in an areas receiving higher rainfall humid regions for its successful cultivation. Itís grown an altitude up to 1200m. It grows best in between the temperature range of 130c to 370c. They are much tolerant to heat and frost condition then limes.

Propagation

The best method of propagation of lemon is T budding.  Apart from this stem cutting and layering also used for propagation. Trifoliate orange and Jatti Katta are compatible rootstocks for lemon.

Cultivation

Planting: Pits of 6ox 60 x 60 cm size are dug 5 to 6 meters apart each way and filled with 30 to 40 kg. Farm yard Manure or compost and Top soil along with 2 kg superphosphate. One year old, healthy budded seedlings are used for planting. Most ideal season for planting is the onset of monsoon (June - July) for  lemon. However, in heavy rainfall area September-October would be appropriate planting season

Spacing- the spacing in lime is varies with the varieties, rainfall, and soil. normal spacing of lemon is 6m X 6m.
Manures and fertilizers

In lemon the nitrogen should be applied in the form of farmyard manure/compost (25%), oil cake (25%), and chemical fertilizers (50%). The fertilizer dosage for lemon plants are N, P2O5, and K2O at 500:300:500g/plant/year.

Interculture

Ploughing, spading of basins, weed control, etc., are important operation for soil aeration and health. Chemical control of weeds with pre emergence weedicide like diuron (3Kg /ha), simazine (4Kg/ha), glyphosate (4 l/ha), paraquat(2 l/ha) used.

Intercrops

Leguminous crops like soybeans, peas, French bean, cowpeas, gram, groundnut etc., are grown in lemon orchard. Intercropping is done during initial 3-4 year after planting.

Training and pruning

Training system followed in lemon is open centre method. Trees are trained to form a low headed open centered crown which can harvest maximum sunlight. This can be achieved by removal of twigs annually. Very light annual pruning is advisable for lemons to remove dried and diseased branches, to stimulate new growth and to maintain optimum production.

Harvesting

It bears fruits almost throughout the year. The fruits are non- climacteric. Generally the lemons are harvested with the clippers. Mechanically by tree trunk shakers and abscission chemicals are used.

Yield

Economic life of plant is 15 to 25 years. The fruit yield is depends on the region, soils, climate, varieties etc., the average yield of lemon is 200-300 fruits/plant. Seville lemon yields 10Kg /plant in south Indian condition. Pant lemon-1 in Uttar Pradesh produces 32Kg fruits/plant. In north east India, Assam lemon produces on an average 150 fruits/ plant.

Post harvest management

After harvesting, fruits are stored at room temperatures for varying periods. The lemons are stored at 7-80c with 85-90% RH for longer period. Wax coating (12%)+ capton (0.1%) increase the shelf lime of baramasi lemon up to 35 days. In case of eureka lemon storage period is increased by use of 2, 4-D and 2, 4, 5-T in was emulsion.
