“…Spatial complementarity in exploring the root zone can occur by species with contrasting root architecture [13], such as maize and turnip. Additionally, that the oat had reached maturity and was senesced in the present study would have reduced oat CP concentration (Table 2) [29]. Oat CP concentration in the present study was slightly less than the 150 g kg −1 average of five cultivars measured by others [19], but consistent to that measured for more mature oat [29].…”

“…Between-year and between-site variability in the benefits of intercropping have been attributed to environmental conditions, with greater benefits observed in semiarid environments [14]. At 2 Mg DM ha −1 , aboveground biomass yield of oat sown in late summer and harvested in the autumn in this study (Table 2) was somewhat less than that reported by others for late summer sown oat [19,20,29]. The mid-summer-sown oat in the present study was headed when harvested.…”

Turnip aboveground CP concentration measured in this study was consistent to that measured for turnip planted in August [18] and for three species of brassica (Brassica campestris L. x napus L., B. rapa L., and Raphanus sativus L.) [27].…”

Relay Intercropping with Cover Crops Improved Autumn Forage Potential of Sweet Maize Stover

et al. 2018

Maize (Zea mays L.) stover is used globally as winter feed for livestock but the nutritive value is low, requiring supplementation. A 2-year randomized complete block study with three replicates at New Mexico State University's Alcalde Sustainable Agriculture Science Center compared sweet maize (Zea mays var. rugosa; maize-alone) with sweet maize relay intercropped with oat (Avena sativa L.; maize-oat) or turnip (Brassica rapa L.; maize-turnip). Relay intercropping had no effect (p > 0.05) on sweet maize stover dry matter (DM) yield and there was no difference in aboveground biomass DM yield of the intercropped species. Turnip aboveground biomass had greater crude protein concentration and 48-h in vitro dry matter disappearance (IVDMD) than oat aboveground biomass. Relay intercropping with turnip improved sweet maize stover IVDMD (443, 439, and 515 g IVDMD kg −1 for maize-alone, maize-oat, and maize-turnip, respectively, p < 0.0001). Intercropping increased animal gains compared to maize-alone (0.36, 0.52, and 0.59 kg/day for maize-alone, maize-oat, and maize-turnip, respectively, p < 0.02), likely due to provision of additional crude protein. Relay intercropping oat or turnip into sweet maize is viable for improving sweet maize stover for fall forage. In addition turnip, specifically, had a positive effect on stover nutritive value.

“…The detergentbased methods are a well-established method to measure composition concentrations. Forage quality laboratories and research groups routinely use these methods [1,3,5,6,8,16,22]. Development of near-infrared spectroscopy (NIRS) calibrations based on the detergent-based methods can be used to predict these components in a high-throughput manner.…”

Cell Wall Composition and Ruminant Digestibility of Various Maize Tissues Across Development

Maize stover, including stalks, leaves, and cobs, has potential utility as a cellulosic biofeedstock. Understanding how total stover ethanol potential is affected by the proportion and quality of major plant components would facilitate the genetic improvement of stover quality and inform decisions regarding which plant parts should be targeted for harvesting. Our objectives were to determine how the proportion and composition of plant components affected ethanol potential and whether there are early season predictors of stover quality at maturity. Twentythree hybrids were evaluated including 20 from a factorial mating design between five silage inbred lines and four commercial inbreds and a brown-midrib3, a Leafy1, and a commercial grain hybrid checks. Plants were harvested and dissected into component parts at developmental stages vegetative 3, vegetative 12, reproductive 3, and reproductive 6 (R6). Tissues were evaluated for acid detergent fiber (ADF), neutral detergent fiber (NDF), and NDF digestibility (NDFD). Stalk was the largest fraction of whole plant dry matter (46.2%) and had the lowest NDFD (3,750 g/kg) at R6. No relationship was found between stalk ADF at early developmental stages and whole plant ADF at R6, suggesting that quality at early developmental stages is not indicative of quality at physiological maturity. Differences were observed among hybrids for ADF and NDF for most plant parts evaluated. Hybrid-bydevelopmental stage and hybrid-by-plant part interactions were statistically significant. This indicates that there is minimal opportunity to identify superior hybrids for biofuel production based on the proportion of total biomass represented by a plant part and its quality at early developmental stages. Maximum conversion efficiency is attained when leaves are harvested compared to other tissue types at physiological maturity.
