Fertilizer Rate and Placement Alters Triticale Forage Yield and Quality

Abstract

On a soil low in available phosphorus (P) and nitrogen (N), 14 combinations of N and P fertilizer rates and placement were compared for ‘Presto’ winter triticale (× Triticosecale rimpaui Wittm.) forage production and forage quality. Increasing broadcast N rates increased forage yield and crude protein percentage while lowering forage fiber components. Additional P fertilizer banded with the seed increased forage yield, but crude protein percentage declined and fiber concentrations increased with the additional P. The most efficient use of the fertilizer resource was experienced with small incremental levels of N or P both banded with seed. Seed‐banded N at 20 lb/acre produced as much quality forage as when 80 lb of N per acre was broadcast and incorporated. Fertilizing with P at 10 lb/acre banded with the seed produced as much or greater forage as N at 120 lb/acre broadcast and incorporated. Both N and P fertilizer, alone or in combination, can efficiently improve forage yield and quality of ‘Presto’ winter triticale, especially when banded with the seed.

Perennial cereal rye performance and comparisons with winter annual cereal forages in the semiarid, subtropical southwestern United States

“…Irrigated cereals grown at Los Lunas had higher CP than at Tucumcari (Table 2), likely due to the additional soil N at Los Lunas (Cazzato, Laudadio, & Tufarelli, 2012;Harmoney & Thompson, 2005); however, MacKown and Northup (2010) found no difference in CP of WW or perennial Crop Science cool-season grass due to split autumn-spring applications totaling 90 or 135 kg N ha −1 . Fiber components and digestibility (ADF, aNDF, and NDFD) and ADL also were higher at Los Lunas (Table 2).…”

Valor nutricional da planta, padrões de fermentação e qualidade da silagem de triticale em seis idades de corte

“…Ao avaliar o efeito do estádio de desenvolvimento das plantas (89 a 122 dias pós-semeadura) de três cultivares de triticale no período de inverno, em Jaboticabal (SP), Jobim et al (1996) (Juskiw et al, 2000). Estudando diversos aspectos relacionados à fertilização da cultivar de triticalePresto, colhido no estádio de botão floral, Harmoney & Thompson (2005) relataram concentrações (% da MS) de PB, FDN e FDA, respectivamente, nas faixas de 5,8 a 13,8%; de 61,5 a 64,5% e de 38,1 a 41,3%. Na Tabela 2, são apresentados os parâmetros de degradação ruminal in situ da MS da forragem verde em função da idade de corte do triticale.…”

Identifying Winter Forage Triticale (×Triticosecale Wittmack) Strains for the Central Great Plains

“…W inter triticale (× Triticosecale Wittmack) is predominantly used as an annual forage crop (Harmoney and Thompson, 2005) in the Great Plains, though it can provide other economic and environmental benefits (e.g., Schwarte et al, 2006a,b; Nance et al, 2007). Triticale grain also can be used as a feed grain or to make flour for use in different products like cookies (Hede, 2001), and the plants can be used as a cover crop during winter periods where bare soils are vulnerable to erosion.…”

“…The problem of seed cost could be reduced by developing forage cultivars with better grain yield. It is important to carefully select cultivars that will achieve high forage yield and quality in late fall or early spring, when additional feed is needed to reduce feed costs (Harmoney and Thompson, 2005), or that have the ability to provide forage over an extended period (Rao et al, 2000). Forage cultivars also need to be selected for high biomass yield and digestibility, as these will increase livestock performance and profitability (Mitchell et al, 2005).…”
