Case Study

Increased pumpkin yield using biostimulants Digester, Mycorrcin and Foliacin

BioStart Limited.

February 2007

Key words
Pumpkin, increased yield, Digester, Mycorrcin, Foliacin.


  • A block was divided into 4 x 11 bed sub blocks (one boom width). Two sub blocks were treated and two were left as a control.

Program used was: 

  • 4lt/ha Digester immediately prior to sowing (18 Oct 2006).
  • 5lt/ha Mycorrcin first true leaf (6 Nov 2006).
  • 1lt/ha Mycorrcin + 1lt/ha Foliacin (11 Dec 2006).
  • 1lt/ha Foliacin (12 Jan 2007).
  • 1lt/ha Foliacin (25 Jan 2007).
  • 1lt/ha Foliacin (15 Feb 2007).
  • On the 23 Mar 2007 6 plots measuring 3m x 8.3m (25m2) were selected from the top, mid and lower areas of the treated and untreated areas. The pumpkins were weighed, counted and sorted by weight – small: less than 1.4kg, medium: 1.4kg – 3kg, large: +3kg.
  • Right: Field weighing- large, medium, small.
