Abstract:
Interest in the potential of sweetpotato (Ipomoea batatas) for the production of industrial products is increasing. As part of an effort to evaluate the potential of sweetpotatoes for starch and anthocyanin production in the southeastern United States, a 5 × 5 North Carolina mating design II (NCII mating design) was developed to estimate the relative importance of general and specific combining abilities for dry matter (DM) content, total monomeric anthocyanin (TMA) concentration, fresh yield, and total DM and anthocyanin yields. All five traits had significant general combining abilities (GCA

Abstract:
A field trial was conducted at Shika, Northern Nigeria to examine the effect of two plant spacings: 30 x 25cm (SI) and 60 x 25cm (S2), four phosphorus leves (75, 100, 125 and 150kgP.ha) and harvesting at 86, 100, 114 and 128 days after planting (DAP) on forage yield of La-blab purpureus cv. Highworth. Closer spacing significantly gave higher (P < 0.05) leaf, stem and total dry matter (DM) yields that wider spacing. Application of phosphorus fertilizer did not significantly (P > 0.p05) influence stem and total DM yield. Leaf DM yield was affected (P < 0.05) by the levels of fertilizer

Abstract:
A survey of commercial fodder beet crops across Canterbury and Southland was undertaken to determine average yields and to provide some basic information on commercial crops. Commercial yields were approximately 19 t DM/ha but higher yields (34 t DM/ha) were achievable. Dry matter content (DM%) of bulbs was higher for lighter than for heavier bulbs. Variation in DM% between bulbs was greater than the variation between parts (inner and outer fractions) of the bulb suggesting a rapid method of sampling multiple bulbs may lead to increases in accuracy of DM% assessment. A rapid coring method was

Observed and simulated potential dry matter (DM) yields of the timothy (Phleum pratense L.) primary growth were compared to disentangle the yield trend from the effect of year-to-year climatic variations in an ageing sward (1 to 7 yr). Observed DM yields were close to simulated potential DM yields in the first 4 yr, but they were around 60% of simulated potential DM yields in the last 3 yr. This confirms that variations in air tempera

Abstract:
The trade-off between forage yield and quality would be minimized by selecting a genotype that produces high-quality forage regardless of yield. This paper attempts to detect forage quality differences among timothy (Phleum pratense L.) genotypes that are independent of yield. Two separate field experiments were conducted from 1993 to 1995 on an Ando loamy sand in Hokkaido, Japan. For exp. 1, timothy plants (cv. Nosap) were harvested at various maturity stages for the first, second, and third cuts in 1994 and 1995 to evaluate the relationships of crude protein (CP) and neutral detergent fibre

Maize (Zea mays) grain yield in New Zealand has increased linearly, on average by 104 kg/ha/year (R2=0.51) while maize silage yield has increased linearly on average by 166 kg DM/ha/year (R2=0.47), based on strip trial data (1991-2015 for grain, and 1996-2015 for silage). Over the same periods, grain yields (based on 14% moisture content) have increased on average in the lower North Island (LNI) by 175 kg/ha/year (R2=0.45) while average silage yields have increased in the Waikato by 212 kg DM/ha/year (R2=0.48), in the LNI by 177 kg DM/ha/year (R2=0.31) and the South Island by 155 kg DM/ha/year

Pastures are the main source of energy and nutrients for dairy cows in the irrigated dairy region of northern Victoria, yet annual production and utilisation of pasture have remained static over the last 20 years. Previous small plot research has shown that pasture yields can be increased through systems of soil modification that improve soil structure and alleviate limitations to root growth. We compared the yield and nutritive characteristics of 4 forage species [tall fescue (Festuca arundinacea), lucerne (Medicago sativa), phalaris (Phalaris aquatica) and perennial ryegrass (Lolium perenne)

Dry matter (DM) yield, in vitro digestibility (DMD%), and nitrogen (N) concentration were determined for 28 cultivars of millet (Echinochloa utilis), hybrid forage sorghum (Sorghum spp.) and maize (Zea mays), under irrigation at Kyabram, Victoria. These summer fodder crops produced large amounts of digestible dry matter (DDM) under intensive irrigated management in northern Victoria, indicating their potential importance for animal production in irrigated warm temperate regions, where pasture dominates the present land use.

We consider regularizations of the convective term that preserve symmetry and conservation properties exactly. This yields a novel class of regularizations that restrain the convective production of small scales in an unconditionally stable manner Numerically, one of the most critical issues is the discrete filtering; properties required are, in general, not preserved by classical LES filters. Alternatively, here we propose to construct filters with the general form F = I + Σm = 1M dmD˜m where D˜ is the discrete diffusive operator. Then, the coefficients, dm, follow from the requirement that,
