SOYBEAN PRODUCTION

• Alexander E. Santos

Background

• Soybean (Glycine max (L)
• one of the most important legumes
• describe as wonder crop of the 20th century
• annual, herbaceous, pod-bearing legume
• contains 40-45 protein
• most nutritious crops
• served as green manure crop

3
Uses of Soybean

• Soybean as Feed
• - high protein content (40-45) in terms
  of amino acid composition
• - adequate amount of vitamins minerals
• - as fodder forage

4

• Raw Materials for Industry

• - used as solvent and in making dyes,
  synthetic resins, lacquers, glues, paper
  coating
• - soybean oil for foaming, dispersing and
  wetting agents (lecithin)

5

• Soybean as Food
• - ingredients in traditional meal dishes
• - fermented products such as soy sauce
  (toyo), soy cheese, soy paste, etc.
• - soy bean milk
• - Net Income (P3,835/ha at 1.5t
  P10,000/ha at 2t)

6
Production Management

• Recommended Soybean Varieties

7

• Soil Requirements
• - deep, well drain fertile clay loam or
  sandy loam
• - with soil pH 5.8-6.5
• Climatic Requirements
• - less rainfall during wet season and
• only a short dry season
• - temperatures ranges from 10ºC 40ºC

8
Land Preparation

• Soil must have favorable moisture

• 2-3 times plowing for carabao drawn
• implements

• 2 plowing is enough using 4WT

9
Planting Fertilization
-Furrow distance 40-50 cm apart -seed are drilled
at the rate of 25- 30 per linear meter or 50-60
kg per ha - plant density 300,000-400,000
plants/ha - 2 bags 14-14-14(basal)

Cultivation, Weeding Side dressing
Off-barring 15-21 DAP Apply remaining 2 bags
triple 14, 30-35 DAP Hilling-up 30-35 DAP

Prevention Control

• use resistant varieties
• Practice crop rotation
• Practice IPM (bio-control)
• Chemical control

17
Biological Control
Earwig
Parasitoid
Trichocards
18
Harvesting/Drying

• indicated by the yellowing of the
• pods and falling leaves
• moisture content must be 16-18
• drying systems used for corn
• grain sorghum are adaptable to
• soybeans
• Split soybean are susceptible to
• Molds and fungi invasions

19
Storing

• Store uniformly dried soybeans at
• 14 MC if stored less than 6
• months and 11 for longer storage
• Practice Sanitation, Aeration and
• Monitoring (SAM)
