OVERVIEW
- Boron deficiency in cotton may cause a distorted, stunted terminal, abnormal uppermost leaves and aborted flowers (Figure A).
- Soil applications of B are traditionally made with potassium prior to planting and/or as a foliar application at early bloom.
- Aspire® with Boron nourishes plants at the root level so nutrients are available when and where plants need them.
TRIAL DETAILS
Locations and Crop Management:
Crop: Cotton (Gossypium hirsutum L.)
Year: 2013
Locations: 6 trials across cotton growing regions of the U.S. (AL, GA,LA, MS, SC, TX)
Data Source: Field studies conducted by third-party, independent researchers.
Experimental Design: Small-plot RCBD with 4 replications.
Cropping Conditions: All trials conformed to local cropping practices.
K Rate: 120 lbs K₂O/ac
B Rate:
Preplant: MOP + B blend (1 lb B/ac)
Preplant: Aspire® (1 lb B/ac)
Preplant + Foliar: MOP + B blend (1 lb B/ac) + early bloom: (0.5 lb B/ac)
Preplant + Foliar: Aspire® (1 lb B/ac) + early bloom: (0.5 lb B/ac)
Results
SUMMARY
- Aspire® yielded higher in both preplant and preplant + foliar applications. Yields were higher with 1.5 lbs B/ac compared to 1 lb B/ac.
- A preplant application of Aspire® (1 lb B/ac) outyielded an MOP + B blend (1 lb B/ac) by 22 lbs lint/ac and MOP by 64 lbs lint/ac.
- The preplant Aspire® application (1 lb B/ac) with foliar application (0.5 lb B/ac) provided an additional 26 lbs lint/ac over the comparable MOP + B blend (1 lb B/ac) with foliar application (0.5 lb B/ac).
- The higher yields with Aspire® compared to other treatments demonstrate the advantages of uniform nutrient distribution from Nutriform® technology.
