In each of our services, Greenhouse Trial Centre combines cutting-edge technology with top-class Agri-expertise to ensure sustainable growth and environmental stewardship.
POT TRIALS
- Crops: Monocot and dicot crops are to be used as the test crops
- Control plus different treatments at 1/2x, 1x , 2x normal application rates for Group 3, and applicable chemical dose rates for Crop Protection products.
- 8 Replicates (four for root study) to have enough degrees of freedom for ANOVA’s
- 120 Pots per table
- Trail duration – appropriate time – 4-5 weeks for root studies, 6-8 weeks for plant biomass production
- Weekly photos of comparative treatments
- Soils, Hydroponic solutions or growth media
- Own soil or growth media for evaluation of specific related problems
- Monitoring nutrient dynamics in fertilisers and lime related products
- Brix Readings if needed
- Monitoring of plant sap dynamics on young and old leaves for diagnosis
REGISTRATIONS
- Certificate of analysis of the active ingredient must be supplied.
- Certificate of analysis from an ISO 17025 accredited certified laboratory indicating the highest levels of potentially harmful elements and MRL analysis.
- Scientific proof of efficacy relating to every claim made in favour of the product.
- Statistical analysis and logical scientific conclusions
RECOMMENDATIONS
- If from the greenhouse trial the product in combination with fertilisers, or on its own, gives statistically significantly higher biomass yields (95% surety) than the control, it qualifies for a Group 3 Registration.
- Crops and soils react differently to fertilisers and bio-stimulants, this needs to form part of the original protocol, and the intended claims envisaged for the product marketing. Additions to fertilisers of bio-stimulants need to be seen in context, keeping in mind that interactions do occur. Sometimes it is necessary to add additional ameliorants such as growth hormones, amino acids, bases, surfactants, energy sources etc. On their own they may not show reactions, but in the right combinations, efficacy can be vastly improved.
- Tank combinations of crop protection products; time of application and the effect of a chemical on a specific variety becomes more and more important as farmers are seeking more precision-based applications. Our Team can assist in the decision making.
REPORTS
- Full plant analysis of pooled replicates, unless element uptake needs to be verified, then replicates are analysed separately for ANOVA’s.
- Full soil analysis of pooled replicates, unless as above.
- Brix readings during growth on young and mature leaves if required to ascertain dynamics of elements.
- Independent statistical analysis.
- Final signed PDF report with weekly photos of comparative treatments and control.
