Soy (India)

Study details

  • Date: 2003-2004
  • Location: Punjab, India
  • Soil: Alluvial soil, loam, 0.24-0.30% organic content, 132-145 kg/ha total nitrogen, 14.2-13.4 kg/ha available phosphor, 178-190 kg/ha available potassium, pH = 8.2-8.3
  • Crop variety: Jundan 20
  • Fertilizers: Water soluble particles with B ≥10%, Zn ≥10%, 400 g/mu was spread in the soil when the maize seeds were sowed together with routine fertilization.
  • Trial design: 3 treatments (0.75, 1.00, 1.25 kg B/ha), 3 replications, randomized block design


Applications of 0.75, 1.00 and 1.25 showed significant yield increase over the control. There was no significant effect between treatments.
