bhindi productionhow to grow and care okra crop



(Syn: Lady’s finger, Bhindi)

(Abelmoschus esculentus (L.) Moench) (2n = 130)

(Hindi: Bhendi)

Okra is predominantly a crop of tropics and subtropics. It occupies fifth position, next to

tomato, in area under vegetables in the country with a production of 33.24 lakh metric tonnes

from an area of 3.47 lakh hectares. The crop is cultivated for its young tender fruits, used in

curry and soups after cooking. It is a good source of vitamins A and B, protein and minerals. It

is also an excellent source of iodine and is useful for the treatment of goiter. Fruit is useful

against genitor-urinary disorders, spermetorrhoea and chronic dysentery. Fruits are also dried

or frozen for use during off-season. Dried fruit contain 13-22% edible oil and 20-24% protein

and is used for refined edible oil. Dry fruit skin and fibres are used in manufacture of paper,

card board and fibres. Root and stem are used for clearing cane juice for preparation of


Origin and distribution

Okra originated in tropical and subtropical Africa. Existence of a large number of related

species with wide variability and dominant characters suggest possible role of India as a

secondary centre of origin.

India is the largest producer of okra in the world. It is also used as a vegetable in Brazil,

West Africa and many other countries. In India, major okra growing states are Uttar Pradesh,

Bihar and West Bengal.

Taxonomy and botany

Cultivated bhendi belonging to Malvaceae was

earlier placed under Hibiscus esculentus L. Since its

calyx, corolla and staminal column are fused together and

fall down at anthesis (caduceus), it was renamed as

Abelmoschus esculentus L. in Hibiscus, calyx is

persistent. Cultivated bhendi is an annual herb with

duration of 90-100 days. Flowers are bisexual and often

cross-pollinated. Time of anthesis is 8.00-10.00 a.m.

Dehiscence of anthers occurs 15-20 minutes after

anthesis and is completed in 5-10 minutes. Pollen fertility

is maximum in the period between one hour before and after opening of flower. It takes 2 to 6

hours for fertilization after pollination. Stigma is receptive at opening of flower and hence, bud

pollination is not effective in okra. Fruit is a capsule. Usually fibre development starts from fifth

to sixth day.

Most of cultivated varieties are amphidiploids with 2n=130. A. esculentus is noted for its

chromosome polymorphism and 2n ranges from 72 to 144. It tolerates addition or deletion of

one or a few chromosomes. The chromosome number of A .esculentus is 2n=130 which is

evolved by crossing. A. tuberculatus (2n=58) with A. ficulneus (2n=72). The F1 developed was

subjected to colchicines treatment to make it an amphidiploid. A. esculentus (2n=130).

Similarly, A. caillei, a complex polyploidy, can be evolved by colchicines treatment of F1

of cross between A. manihot and A. esculentus.

Four species viz., A. esculentus, A. manihot, A. caillei and A. moschatus include both

cultivated and wild forms.

Crop improvement

Yellow vein mosaic virus disease being a serious problem in okra cultivation, concerted

effort was made to develop high yielding as well as YVMV resistant varieties in the country.

With development of YVMV resistant variety, Pusa Sawani, most of the primitive low yielding

local cultivars has become less significant. After break down of resistance of Pusa Sawani,

research on virus resistance was intensified at various research centres in India and it resulted

in development of a number of YVMV resistant varieties.

Various methods like plant introduction (Perkin’s Long Green), single plant selection and

pure line selection from local collections (Pusa Makhmali, Salkeerthi), selection from bi-parental

crosses (Pusa Sawani from IC 1542 x Pusa Makhmali) and selection from complex crosses (sel

2 from (Pusa Sawani x Best 1) x (Pusa Sawani x IC 7194) were used. YVMV resistant variety

Susthira developed at the Kerala Agricultural University is A. caillei. Pedigree selection in the

segregating populations of resistant YVMV varieties resulted in Hisar Unnat (Sel 2-2 x Parbhani

Kranthi) and Varsha Uphar (Lam selection 1 x Parbhani Kranthi). Related wild species were

also utilized in development of YVMV varieties like Parbhani Kranti (A. esculentus cv. Pusa

Sawani x A. manihot ssp. Manihot), Punjab 7 (A. esculentus cv. Pusa Sawani x A. manihot ssp.

Manihot cv. Ghana) and Arka Abhay (A. esculentus x A. manihot ssp. Tetraphyllus). MDU 1

and Punjab 8 (EMS 8) were developed through mutation breeding using gamma rays and EMS


Exploitation of hybrid vigour

A large number of seeds in a fruit and large size of flowers are favourable factors for

exploitation of heterosis in bhendi. A number of hybrids resistant / tolerant to YVMV were

developed in public and private sectors. Most of the hybrids were developed by hand

emasculation and hand pollination. Two F1 hybrids developed by TNAU are CO.2 and CO.3.

CO.2: AE 180 x Pusa Sawani. Fruits very long (22-25 cm), thick, 7-8 ridged and light green in

colour. Productivity 15-16 t/ha. Susceptible to YVMV.

CO.3: Parbhani Kranti x MDU.1. Fruits very long (22-25 cm), thick, 7-8 ridged light

Green in colour. Productivity16-18 t/ha. Moderately resistant to YVMV.

COBhH 1: Varsha Uphar x Pusa A4 (T). Fruits are dark green, long, slender with five ridges.

High yield – 22.1 t/ha. Resistance to yellow vein mosaic virus


Bhendi is a typical tropical or sub-tropical crop and cannot tolerate frost. Performance is

also adversely affected by drought, low night temperature and shade. Even though fertilization

and seed set are affected during high rainfall, growth of plant and subsequent productivity is

exceptionally good rainfall areas. Under high temperature and low humidity, plant growth is

stunted and will be shorter in stature. Similarly flowers drop when day temperature exceeds




Okra prefers loose, well drained and rich soil. The ideal pH for growth of plants is 6-8.


In areas where winter is mild, bhendi is grown throughout the year. Since it cannot

tolerate frost and low temperature, only two crops are taken in plains of North India. As kharif

crop, seeds are sown from May to July and as a spring summer crop, sowing is done during

February-March. In hills of North India bhendi is sown during March-April.

Seed rate and spacing

During summer, vegetative growth is relatively less and seeds are sown at a closer

spacing of 45 x 20 cm or even less. Seed rate required is 18-20 kg / ha. During kharif, plant

grows vigorously with more branching and seeds are sown at wider spacing of 60 x 30 cm for

branching types and 45 x 30 cm for non-branching types. Seed rate recommended for kharif

crop is 8-10 kg/ha. For harvesting smaller fruits for export, three rows planting with a spacing of

20-30 cm between rows and 20 cm within a row is advantageous. Distance between two sets is

kept as 60 cm. This system has the unique advantage of easiness in inter cultural operations,

harvesting, application of plant protection chemicals, etc.

Land preparation and sowing

Field is ploughed thoroughly for 2-3 times for making soil to a fine tilth. Ridges and

furrows or raised beds are prepared and dibbling on sides of ridges or on raised beds sows

seeds. Soak seeds for 6-12 hours before sowing to enhance germination during summer.

Manuring and fertilizer application

Apply 20-25 t of farmyard manure as basal dose at the time of final ploughing. A dose of

150 kg each of N, P2O5 and K2O is recommended for Pusa Sawani in the coordinated trials.

NPK recommendation varies from state to state and a lower dose of 50:8:30 kg N is

recommended under Kerala condition. One third dose of N, full P and K are to be applied as

basal dose. Remaining N has to be applied in two split doses, 4 weeks after sowing and at

flowering and fruiting stages. Split application of N in soil at every 3rd picking is advantageous

for getting high yield, for increasing number of harvests and to maintain size of fruits towards

last harvests.

Application of Fertilizers in Tamil Nadu

Apply FYM 25 t/ha, N 20 kg, P 50 kg and K 30 kg/ha as basal and 20 kg N/ha 30 days

after sowing. Apply Azospirillum and Phosphobacteria each at 2 kg/ha mixed in 100 kg of FYM

before sowing.


Water stress at flowering and fruiting stages will drastically influence growth of plants,

size of fruits and yield. Immediately after sowing, field is irrigated. Subsequent irrigation is

given at fixed intervals depending on texture of soil and climate. In black soils, irrigation is done

at 5-6 days interval.


Weed growth should be under control till crop canopy covers fully. This is achieved by

frequent hoeing, weeding and earthing up. Used of weedicides like Lasso (2 kg a.i./ha) or

fluchloralin (1.5 kg/ha) or Metolachlor (1.0 kg a.i./ha) and one hand weeding at 45 days after

sowing was very effective and financially viable under the All India Co-coordinated trials.

Harvesting and yield

Harvest fruits when they attain maximum size but still tender. Fruits of 6-8 cm long are

preferred for export purposes. This is usually attained by 5-6 days after opening of flower.

Harvesting is done in alternate days with a knife or by bending pedicel with a jerk. For

harvesting, cotton cloth hand gloves should be used to protect fingers from stinging effect. It is

advisable to harvest in morning hours since fruit hairs will be soft. Sprinkling water on pods

during night will keep them cool and fresh for market.

Post-harvest management

Fruits after harvesting are graded and filled in jute bags or baskets or perforated paper

cartons and sprinkled with water. Pre-cooling of fruits before packing maintains turgidity of fruits

and will save it from bruises, blemishes and blackening. This is usually done before packing

fruits in perforated cartons of 5-8 kg before transporting to refrigerated van for export.

Yield 6.0 – 8.0 t / ha for spring-summer crop

10 – 12.5 t / ha for kharif crop.

Pests and Diseases


Yellow Vein Mosaic Virus Disease

This is the most serious disease of bhendi. Characteristic vein clearing is the typical

symptom and yield loss may be up to 100% depending on stage of occurrence of the disease.

Fruits of virus affected plants turn to cream or white in colour. Virus is transmitted through a

whitefly Bemisia tabaci. Removal of weeds susceptible to mosaic from nearby fields, control of

white fly, uprooting and burying of affected plants, adjusting time of sowing and cultivation of

resistant varieties like Arka Anamika, Arka Abhay, Susthira etc. are recommended for raising a

disease free crop. Recently, a hybrid COBhH 1 has been released from HC & RI, TNAU

Coimbatore which is resistant to YVMV.

Cercospora leaf spot

This disease is serious when there is high humidity in atmosphere and is common in a

seed crop. Sooty, black mouldy growth of pathogen appear as under surface of leaves and

finally leaves dry off and fall down. Mature pods are also attacked and show blackish spots.

Spraying with Bavistin (0.1 g /1) or Bordeaux mixture at fortnightly interval will control the


Powdery mildew

This is caused by a fungus Erysiphae chicoracearum under prolonged humid conditions.

White powdery pistules appear on lower surface of leaves resulting in yellowing and death of

leaves. Spraying of wettable sulphur (2g/l) at fortnightly interval is recommended for control.

Insect Pests

Jassids (Amrasca biguttula biguttula)

Wedge shaped pale green jassids suck sap from undersurfaces of leaves causing

marginal yellowing, cupping and drying of leaves. Due to intense hopper burn, defoliation also

occurs. Infestation is serious during summer. Prophylactic spray of neem oil-garlic mixture at

fortnightly intervals is advantageous for avoiding pest incidence.

Fruit borer

Borer infestation results in toppling and death of young seedlings, withering and drying

up of individual leaves and central shoot. Fruits will be damaged severely. Spray of carbaryl or

thiodan or endosulfan or fenvalerate or cypermethrin or deltamethrin is effective for control of

borer. Summer ploughing and clean cultivation are also helpful in reducing pest infestation.


Root knot nematode infects roots causing galls premature leaf fall, wilting and decline in

growth and fruit production. Symptoms in the field generally appear as well defined patches.

Crop rotation with non host plants like wheat, rice and corn should be practiced as a regular

measure. Successive deep ploughing during summer and soil solorisation gives very good

control. Treating field with nematicides also can be adopted.

Seed production

For seed production, adjust sowing in such a way that dry weather coincides with

maturation and drying of pods and incidence of yellow vein mosaic disease is minimum. Being

an often cross-pollinated crop, provide an isolation distance of 400 m from other varieties. Field

inspection and rouging should be conducted at pre-flowering, flowering and fruiting phases.

Harvesting of initial two fruits will be helpful in promoting growth of plants. Average seed yield is

1.0-1.5 t/ha.
