Aspire® Cotton Boron Study

Objective

Evaluate the yield response of cotton to preplant applications of different potassium (K) and boron (B) sources. [1] MOP (0-0-60), [2] MOP + B blend, [3] Aspire® (0-0-58-0.5B). Compare the yield response of cotton with different preplant K and B sources plus an additional foliar B application at early bloom. [1] MOP + B blend with foliar compared to [2] Aspire® with foliar B.

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

Cotton Yield by Treatment

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.
