Objective:

To compare a soil test recommended Agro-Culture Liquid Fertilizers program to a conventional dry fertilizer program on navy beans.

The AgroLiquid program consisted of 8 gal/A High NRG-N + 4 gal/A Pro-Germinator + 4 gal/A Sure-K + 2 qt/A Micro 500 placed 2×2 with the planter. This program was compared to conventional dry fertilizers consisting of 17 lb/A Urea + 143 lb/A DAP + 103 lb/A Potash + Mn + Zn applied pre-plant incorporated. Navy Beans were planted into a conventional tilled soil on June 5th at a population of 110,000 in 30″ rows. These same treatments are applied nearly every year to continually prove the effectiveness of AgroLiquid nutrition. All rates were applied according to the target fertilizer rate of 34-66-64. Yields of the comparison and a no fertilizer check appear on the chart below.

Navy Bean Fertilizer ProgramsConclusions:

  • The AgroLiquid program shows over a one hundred pound/A yield advantage over that of conventional dry fertilizer.
  • A liquid program using safe and highly efficient nutrients from Agro-Culture Liquid Fertilizers that is easy to apply with a planter gives plants an advantage.
  • Applying less pounds of nutrients saves time and handling.

Objective:

To determine if an early foliar application to Navy Beans has an advantage in 30” rows over a later application time.

Navy Beans have shown over the years in North Central Research Station testing that they respond very well to foliar applications of nutrients such as ferti-Rain which has a blend of primary, secondary and micro nutrients. These applications have typically been made at the flowering or vine stage. In 2012 an experiment, on 15” rows, testing earlier foliar applications showed an advantage at the three trifoliate when compared to the vine stage application. A repeat of that test was made on 30” rows for multiple years of data. All treatments received the same 2×2 planter applied nutrients. Foliar applications were made at the third trifoliate or the vine stage of the dry beans. Yield results are in the table below.

Navy Bean Foliar Timing ComparisonConclusions:

  • The earlier application of 2 gal/A of ferti-Rain at the third trifoliate stage had a small yield advantage over the later application.
  • Either timing of a foliar application of ferti-Rain did improve yields over the standard planter applied program without a foliar application.
  • A foliar application can be made between the third trifoliate and vine stage as needed with other crop protection products.

Objective:

Compare yield response of foliar fertilizer applications at different growth stages. Three foliar products (ferti-Rain, FK-12 and FHP-12) were used, each at a 2 qt/A rate. There was no difference in yield effects between any product, so the yields of each product were averaged for the three growth stages. Applications were made using the Hagie plot sprayer. The timing effects appear in the chart below.

Foliar Application Timing on Navy BeansConclusions:

  • Foliar applications made at the 4th trifoliate significantly increased yield over the flowering and 4th trifoliate + flowering time application.
  • Two foliar applications did not have a combined effect on yield.
  • Continued research is needed to see if foliar feeding at the 4th trifoliate proves to be practical application timing.

Objective:

To compare Agro-Culture Liquid Fertilizer products with a conventional fertilizer program for dry beans.

The AgroLiquid program for this year includes a comparison of 8 gal/A of Sure-K to 8 gal/A of K-10. These products were added to 1 gal/A Pro-Germinator + 2 qt/A Micro 500 + 14 gal/A High NRG-N and placed 2 x 2 with the planter. The experimental product K-10 has shown good results when used to replace Sure-K in a planter program. Another option added to the AgroLiquid program to address the lower soil test level of 6 ppm Sulfur is the 2qt/A of accesS. Adding accesS into the 2 x 2 planter program is an excellent way to boost the availability of this nutrient. The dry fertilizer program consists of 185lb/A of 0-0-62 + the micronutrients 4lb/A Zinc and 8 lb/A Manganese that were applied with the Gandy air delivery system and incorporated into the soil ahead of planting. This treatment also used 20 gal/A of 28% UAN for its nitrogen source applied broadcast after planting. The results appear in the following graph.

Fertilizer Program Comparisons in Navy BeansConclusions:

  • Foliar applications made at the 4th trifoliate significantly increased yield over the flowering and 4th trifoliate + flowering time application.
  • Two foliar applications did not have a combined effect on yield.
  • Continued research is needed to see if foliar feeding at the 4th trifoliate proves to be practical application timing.

Objective:

Evaluate different foliar product applications and their ability to be combined with a planter applied program to increase yield. This year’s experiment included two new experimental products: FK-12 is a foliar Potassium product and FP-12 is a foliar Phosphorus product. Previous testing with foliar applications has shown to be advantageous in a dry bean crop and this continued testing verifies product performance.

Foliar Application Effects On Navy Bean YieldConclusions:

  • As in years past, the application of 2 qt/A of ferti-Rain gave a yield advantage, demonstrating ferti-Rain as a beneficial foliar application.
  • Results of using 1 gal NResponse + 2 qt/A eNhance as a foliar treatment are similar to a 2010 (270 lb/A increase) and 2011 (170 lb/A increase) experiment that used the same rate. This year’s increased yield of 220 lb/A over the planter only program gives a three year average increase of 220 pounds per acre for using these products.
  • Highest yield was achieved using the planter program + 2 qt/A FK-12 which yielded 340 pounds over the planter-only program. This could be attributed to the extra usable Potassium provided by this experimental product.

Objective:

Evaluate placement options for Agro-Culture Liquid Fertilizer products in a planter-applied program for Navy Beans.

Fertilizer is not usually recommended for in-furrow placement with Dry Bean seed due to injury potential. However, some growers are questioning that position and are curious about the effects of low-rate planter-applied options. The North Central Research Station can do the tests to determine if a recommendation change is warranted. As with any research, more than one year’s data is required to prove a significant yield advantage and potential for detrimental effects. Planting conditions on June 6th were very favorable, with adequate moisture and temperature to achieve quick germination and emergence. These types of conditions do not favor seedling injury, so results should be reviewed carefully.

Navy Bean Planter Fertilizer Placement ComparisonConclusions:

  • Highest yields were achieved using a 2 x 2 application of a full planter program with High NRG-N broadcasted.
  • Yields from treatments utilizing 2 x 2 placement of both Pro-Germinator and Sure-K, yielded significantly higher than the unfertilized check.
  • Continued research should be completed to determine if in-furrow applications can be a safe practice every year with differing environmental conditions. This research is not promoting in-furrow placement at this time.
  • Any planter placed Pro-Germinator and Micro 500 did not result in yields higher than the “All 2 x 2”. However, this may be due to the broadcast placement of Sure-K.
