Package of Practice for Soyabean

SOYBEAN ( Glycine max (L.) Merr.)

Introduction : Globally legumes play a vital role in human nutrition since they are a rich source of protein, calories, certain minerals and vitamins. Among which soybean is probably the largest source of vegetable seed oil (20%) and protein (40%). Owing to the nutritional and health benefits of soybean, it excited the growers in recent years. Similarly other pulse crops like red gram, black gram, Moong, Bengal gram, Urad dal has good nutritive value and the area under pulses production is taken up in different states in India. 

Soil and Climate:

Well drained and fertile loam soils with a pH between 6.0 and 7.5 are most suitable for the cultivation of pulses. Sodic and saline soils inhibit germination of seeds. Water logging is also injurious to the crop.  Pulses grow well in warm and moist climates. A temperature of 26 to 30OC appears to be the optimum. Soil temperatures of 16OC or above favor rapid germination and vigorous seedling growth. Day length is the key factor in most of the pulses, as they are short day plants. 


Field preparation:

Prepare the main field by ploughing and harrowing and 4 to 5 tons per acre of FYM or compost is applied at the time of field preparation. Add 90 - 100 kg of Bio organic Manure (Multiplex Annapurna or Mangala Biogold plus), 1 to 2 kg Bio Jodi (Consortium of Bacillus subtilis and PSEUDOMONAS FLUORESCENS) and 5 kg Bio-activator mixture (Navajeevan - G) per acre. In case of problematic soils with root grubs & termites apply Multiplex Soldier (Entamopathogen) @ 1 kg/acre along with  Bio organic Manure . These pests can also be controlled by application of 5 kg Cartap Hydrochloride 4G (Nagtap or Cartox G or Boregan G).


Seed rate and Spacing :


Seed Rate


Spacing rows x plants (cm)

Soybean (rainfed)

Pure crop - 25

Mixed crop - 15

30 x 10

Soybean (irrigated)

Pure crop - 25

Mixed crop - 15

30 x 10


Note: When grown as a mixed crop add about 20 % of the recommended quantity of NPK fertilizers of the main crop.


Nutrient Management :

All legume crops have the ability to supply their own nitrogen needs provided they have been inoculated with nitrogen fixing bacteria (Sunrise, Azab, Aadhar) along Srushti @ 5 kg per acre. The fertilizers should preferably be placed, at sowing time, about 5-7 cm away from the seed at a depth of 5-7 cm from seed level.
Fertilizer Application.

Recommended dose of Fertilizer Application: NPK – 10:20:40 kg/ per acre

Weed management :

  1. Flumioxazin 50% WP (Chateau, Nozomi, Pledge, Terreiin, Valor) @ 18 -20 g/acre and Diclosulam 80% WDG @ 8 g/acre as pre-emergence were found to be promising herbicides for the management of weeds in pulses.
  2. The tank mix combination of Chlorimuron ethyl 25% WP (Almix, ricestar, whip super) @ 3.6 g/acre + quizalofop tefuryl 4% EC @ 16 g/acre could effectively control the monocot as well as dicot weeds in pulses.
  3. Alachlor 50 EC (Lasso) @ 1.6 litre or Fluchloralin 45 EC (Basalin) @ 1.2 litre per acre, dissolved in 400 litres of water and sprayed after tow days of sowing with sufficient soil moisture.

To control Damping Off

Drench  Metalaxyl + Mancozeb (Ridomil gold 80 WP or Krilaxyl Gold) + Bactinash @ 0.4 g/litre + Humic acid (JIvras) @ 3 ml/liter (100 – 150 ml/plant  drenching).

To control Bacterial Leaf Spot

PSEUDOMONAS FLUORESCENS + BACILLUS SUBTILIS (Multiplex Biojodi) @ 5 – 10 g/litre OR Copper Oxychloride (Nagcoperor Blue Copper or Blitox) @ 2 g/litre OR Copper EDTA (Neel Cu) @ 0.5 g/litre + Bactinash @ 0.4 g/litre OR K – Cykline 0.15 g/litre.

The maturity period ranges from 50 to 140 days depending on the varieties. When the plants reach maturity, the leaves turn yellow and drop and soybean pods dry out quickly. There is a rapid loss of moisture from the seed. At harvest, the moisture content of the seeds should be 15 per cent. Harvesting can be done by hand, breaking the stalks on the ground level or with sickle and threshed.
