Plant Population Effect on Silage Yield and quality

 

Plant Population Effect on Silage Yield and Quality

Objective

  • Determine the effect of plant population on silage yield and quality with elite silage hybrids.

Study Description

Plot Layout: 4-row, 17.77 feet plots; 2 replicates

Locations:

6 site-years in CO and KS

Years:

2011, 2012

Pioneer® Brand Hybrids:
   • P1151YHR  (YGCB, HX1, LL, RR2)
   • P1768YXR  (YGCB, HXX, LL, RR2)
   • P1690HR  (HX1, LL, RR2)
   • P2088YHR  (YGCB, HX1, LL, RR2)

 P1498 Family
   • P1498YHR  (YGCB, HX1, LL, RR2)
   • P1498XR  (HXX, LL, RR2)

 P1625 Family
   • P1625CHR  (RW, HX1, LL, RR2)
   • P1625HR  (HX1, LL, RR2)

Population:

26k, 34k, 42k, 50k, 58k plants/acre

Results

 

  • Across all locations, individual hybrids had a positive silage yield response to increasing plant population.
  • Increasing plant population did not significantly affect the NDFD* value for any of the hybrids tested.
  • All products responded well to increased plant population while maintaining starch content across all populations.

PIONEER® brand products are provided subject to the terms and conditions of purchase which are part of the labeling and purchase documents. 2011-2012 data are based on average of all comparisons made in three locations in 2011 and 2012. Multi-year and multi-location is a better predictor of future performance. Do not use these or any other data from a limited number of trials as a significant factor in product selection. Product responses are variable and subject to a variety of environmental, disease, and pest pressures.  Individual results may vary.
