Mungbean Cultivation in Pakistan


Mungbean (Vigna radiata) is grown mainly for its edible seeds which are cooked, fermented, roasted, sprouted and milled. In Pakistan, mungbean seeds like other pulses, are split in a mill, separated from the husk, and cooked as daal. Mungbean is also used in making soups, curries, noodles, bread and sweets; the seeds roasted with spices are also very popular. Mungbean is easily digestible and high in protein which averages 22-24%. The leftover leaves, stalks and husks of the mungbean plants are used as fodder and the whole plant can be ploughed as green manure for soil improvement.
Mung bean is one of the important kharif pulses of Pakistan. It is also grown during spring season mainly in southern Punjab and Sindh province. Punjab is the major mung bean growing province that alone accounted for 88% area and 85% of the total mung bean production. Cultivation is concentrated in the districts of Layyah, Bhakkar, Mianwali and Rawalpindi. It is mainly grown in Kharif season (July-October). Although it is grown in different crop rotations, about 75% cultivation follows mung bean - wheat crop rotation. With the development of short duration and uniform maturing varieties, mung bean can be fitted in various cropping systems. Research activities on mung bean have been mainly focused on the development of high yielding varieties with wider adaptability, resistant to diseases like Mungbean Yellow Mosaic Virus (MYMV) and Cercospora Leaf Spot (CLS), early maturity and insensitivity to photoperiod.

Growth Habbits

Mungbean belongs to Legume family of plants and are closely related to cowpea (in the same genus but different species). They are warm season annuals, highly branched and having trifoliate leaves like the other legumes. Both upright and vine types of growth habit occur in mungbean, with plants varying from one to five feet in length. The pale yellow flowers are borne in clusters of 12-15 near the top of the plant. Mature pods are variable in color (yellowish-brown to black); about five inches long and contain 10 to 15 seeds. Self-pollination occurs in mungbean plant. Mature seed colors can be yellow, brown, mottled black or green, depending upon variety. These rounds to oblong seeds vary in size from 6,000 to over 12,000 per pound, depending upon variety. Germination is epigeal with the cotyledons and stem emerging from the seedbed.


Mung bean is a warm season crop requiring 90-120 days of frost free conditions from planting to maturity (depends on variety). Adequate rainfall is required from flowering to late pod fill in order to ensure good yield. Late plantings result in flowering during the high temperature and low moisture period in July and August which will reduce yield. High humidity and excess rainfall in the season can result in disease problems and harvesting losses due to delayed maturity.


Mungbeans do best on fertile sandy, loam soils with good internal drainage. This crop does best if grown on fertile soils even without fertilizer application. Higher organic matter will lead to production of vigorous seed. They do poorly on heavy clay soils with poor drainage. Performance is best on soils with a pH between 6.2 -7.2 and plants can show severe iron chlorosis symptoms and certain micronutrient deficiencies on more alkaline soils. Mungbean has phosphorus, potassium, calcium, magnesium and sulphur requirements similar to other legumes which must be met by fertilizer additions if the soil is deficient in these elements.

Time for Sowing

For seed purpose there are two growing seasons of Mung crop.
  1. February to March
  2. June to July
Too late planting results in bloom and pod fill during the hottest, driest period of the summer. In some areas mungbean is planted as a second crop after the small grain is harvested. If this is done planting should occur immediately after the grain harvest with a minimal disturbance of the seedbed.

Land Prepration

Prepare the field by plowing, harrowing and leveling. The soil should be tilled to remove weeds and to prepare a seedbed which will provide good seed-soil contact. The final seedbed needs to be firm with a surface free of clods and debris to allow a good distribution of seeds. If moisture is short, keep pre-plant tillage to a minimum to prevent drying out the top two or three inches.

Sowing Method

Most suitable method of sowing is drilling. Broad casting is usually done in dry regions. The seeds are sown at 2 cm depth with a plant to plant spacing of 8 -10 cm and 30 cm between rows. If the surface layers are dry this depth can be increased to 3 cm if the soil type is one which does not crust easily. The seedlings of mungbean can have a hard time breaking through a thick crust and stands will be reduced. Planting equipment for soybean, fieldbean and cowpea can be used to plant mungbean but careful adjustments must be made to properly deliver and distribute the small seeds. Populations of 150,000-200,000 plants per acre can be achieved.


Mung Beans Varities

Pakistan. It is often included in rice or wheat based cropping systems in the tropics and subtropics. For example in spate irrigated areas, mungbeans are commonly grown along with sorghum for dual purposes i.e. fodders and grains. The short duration, early maturing and uniformity in maturity are now the breeding objectives and such varieties are being developed and seed is multiplied for availability to farmers. Pakistan has released early maturing cultivars using germplasm from international and national sources.
The mungbeans varieties released in Pakistan through National Testing Program are presented as under:

Seed Rate

Seeds used for sowing must be from an authentic source. An authentic source is one that proves the genetic purity and other aspects of seed quality of seed being sown. Seeds used for sowing must also be vigorous, only then one can expect a good field stand. Before sowing shrunken, shriveled, fungal infested and diseased infected seeds must be removed and only good seeds must be sown. Seed rate depending on the variety the seed rate varies from 8-10 kg per acre.


Mungbean is a legume. It has nodulation capability which can fix atmospheric nitrogen into the soil, if seed is inoculated with bio-fertilizer using inoculants developed for nodulation of mungbeans. High and effective nodulation on the roots of the mungbean is an important agronomic factor for enhanced productivity and fixation of atmospheric nitrogen into the soil. Fertilizer at the rate of 50kg or one bag of DAP can be broadcasted and incorporated into the soil before planting.


Mung bean is a short duration and drought tolerant crop therefore it requires less irrigation but to get maximum yield from irrigated areas 350 - 420 mm water is sufficient.

Harvesting and Yield

Pod maturity in mungbean is not uniform because the plants flower over an extended period. This makes it difficult to decide when to harvest. Generally harvest should begin when one half to two-thirds of the pods are mature. Seeds might be between 13%-15% moisture at this time. Swath the plants to allow further maturity of the pods and then threshed. This is an especially useful harvest system for the vine type varieties or when there is delayed maturity or problem weeds present. Swathing should be done earlier in the day to prevent severe shatter losses.
