The extraction of coalbed methane produces a significant amount of coalbed methane co-produced water (CBMW). Coalbed methane co-produced water is often characterized by high levels of pH, total dissolved solids (TDS), sodium (Na) and bicarbonate (HCO−3) and if used for irrigation without treatment, it may be detrimental to the surrounding soil, plants and environment. CBMW ideally should be disposed of by reinjection into the ground, but because of the significant cost associated, CBMW is commonly discharged onto soil or water surfaces. This study was conducted to elucidate the effect of the CBMW (with TDS value of <1500 ppm) at various blending ratios with fresh water on the yield and quality of representative forage crops [i.e., oat (Avena sativa) and alfalfa (Medicago sativa)]. Various blends of CBMW with fresh water reduced fresh and dry weight of alfalfa by 21.5–32% and 13–30%, respectively and fresh and dry weight of oat by 0–17% and 0–14%, respectively. Irrigation with various blends of CBMW and fresh water increased soil pH and soil sodium adsorption ratio. However, forage quality parameters such as crude protein (CP), acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrients (TDN) and relative feed value (RFV) of both forage crops remained unaffected.

This research was conducted to determine performances of seven alfalfa cultivars with different fall dormancy rates in terms of dry matter yield and some quality parameters under Mediterranean conditions throughout the years of 2007-2009. In the study, cultivars were evaluated for dry matter yield (DMY), leaf/stem ratio (LSR), crude protein (CP) content, crude protein yield (CPY), acid detergent fiber (ADF), neutral detergent fiber (NDF), digestible dry matter (DDM) content and relative feed value (RFV). According to average of two year results, there were significant differences among alfalfa cultivars in terms of all characters studied. Mean DMY, LSR, contents of CP, ADF, NDF, DDM and RFV were determined as 18.147 t ha-1, 0.82, 17.4 %, 41.0 %, 49.0 %, 56.9 % and 114. The highest DMY averaged over two years was obtained from cultivar Nimet while lowest one was obtained from Magnum 5. As a dormant cultivar, Magnum 5 was superior in terms of LSR and CP content to the other alfalfa cultivars and it was lower in ADF and NDF content than the others. It was concluded that cultivar Nimet with the highest DMY and CPY yields can be recommended as a non-dormant cultivar for farmers in regions of Turkey with the Mediterranean climate.

Recognizing the potential and importance of cultivating improved forage crops as a means of tackling the recurrent feed shortage facing the study area, seven oat genotypes were tested in randomized complete block design with three replications across two locations for three growing seasons (2014, 2015, and 2016). The study was aimed to evaluate dry matter (DM) and digestible organic matter yield and nutrient composition of oat genotypes. The study revealed that oat genotypes responded differently for herbage dry matter (DM) and digestible organic matter (OM) yield, and quality parameters in both study locations. Averaged over the seven oat genotypes, herbage DM and digestible OM yield. recorded at Bako were higher than Boneya Boshe location across the study periods. The ash ( P  > 0.05) content did not vary among oat genotypes at both testing locations, while variation was observed for DM, crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), in vitro digestibility, and metabolizable energy (ME) constituents. In general, genotypes ILRI 6710 and 5453 showed higher herbage DM and digestible OM yield. Moreover, the two genotypes are also higher in their in vitro digestibility value and ME, DM, and CP contents but relatively lower in NDF, ADF, and ADL fiber constituents, and thus, they are recommended for wider cultivation.

This experiment was conducted to determine the effects of mixture rates of hairy vetch with oat, barley and wheat on dry matter yield and its quality and to determine the suitable mixture when grown as catch crop at Uludag University, Faculty of Agriculture, Agricultural Research and Application Center, Bursa Turkey during 2011-2012 and 2012-2013 growing seasons. The experimental plant entries were Menemen-79 variety of hairy vetch, Faikbey cultivar of oat, Akhisar-98 cultivar of barley and Flamura cultivar of wheat. Nine mixtures (25 % oat:75 % hairy vetch, 50 % oat:50 % hairy vetch, 75 % oat:25 % hairy vetch, 25 % barley:75 % hairy vetch, 50 % barley:50 % hairy vetch, 75 % barley:25 % hairy vetch, 25 % wheat:75 % hairy vetch, 50 % wheat:50 % hairy vetch, 75 % wheat:25 % hairy vetch) were used. Several parameters such as dry matter yield, leaf area index, light interception, crude protein content and yield; ADF (acid detergent fiber) and NDF (neutral detergent fiber) contents and relative feed value have been examined in the experiment. The highest dry matter yield was obtained from the mixtures of 50 % oat:50 % hairy vetch (12 040 kg ha-1) and 75 % oat:25 % hairy vetch (11 748 kg ha-1). According to the two-year results, the higher and quality hay yield (low in ADF and NDF values, high in relative feed value) was produced at 50 % oat:50 % hairy vetch mixture, and this mixture have been proposed to the experimental conditions due to its suitability.

A field study was conducted at St-Augustin, Québec, in 1984 and repeated in 1985 to determine the influence of quackgrass on growth, stand counts, yield and quality of alfalfa established with or without oats as a companion crop. Four densities were obtained by treating quackgrass with glyphosate on 100, 50, 25 and 0% of the plot area. The results indicate that without oats, quackgrass reduced the growth of alfalfa. About 60 d after emergence, a density of 119 shoots m−2 reduced the root dry weight of alfalfa seedlings, but there was no effect of quackgrass on the shoot dry weight and the foliar area in 1984. In 1985, an infestation of 161 shoots m−2 reduced the above three parameters. In both years after establishment, alfalfa stands were thicker in quackgrass-free plots. In pure seedings, quackgrass increased forage yield but decreased the quality of the forage during both seeding years. As compared to the quackgrass-free treatment, a density of 275 shoots m−2 increased forage yields at first cutting of 1985, but there was no effect in 1986. Using oats significantly reduced the aerial growth of quackgrass in both seeding years and at first cutting of year after 1985 seeding. Forage quality, as evaluated by NDF concentration, was reduced at infestations of ca. 300 shoots m−2. Higher infestations were necessary to reduce crude protein concentration relative to that of quackgrass-free alfalfa. The ligno-cellulose content (ADF) was not influenced by quackgrass densities. The critical density of quackgrass in alfalfa lies between 150 and 300 shoots m−2. Above this level, quackgrass significantly reduces the quality of the forage.Key words: Quackgrass, alfalfa, critical density, forage yield, forage quality, companion crop

Abstract Storing hay outdoors can result in detrimental changes in forage quality. Additionally, alfalfa (Medicago sativa L.) cultivar may influence dry matter intake (DMI) and hay waste when feeding livestock. The objectives were to determine the effects of conventional or reduced-lignin alfalfa round bales stored outdoors and wrapped with plastic twine, net wrap, or B-Wrap on forage quality, beef cow preference, and hay waste. Round bales made from reduced-lignin (n = 12) or conventional (n = 12) alfalfa cultivars were baled and stored outdoors for 16 mo. Within each cultivar, four bale replicates were bound with plastic twine, net wrap, or B-Wrap. After storage, bales were fed in a switchback design with period confounded with alfalfa cultivar to 18 lactating Angus cows (Bos Taurus L.). The pairs had ad libitum access to three round-bale feeders where bales of each wrap type were placed for eight 48 h periods. Position of round bale wrap type was rotated according to a Latin Square arrangement. Bales were weighed and waste surrounding each feeder was collected at 24 and 48 h to calculate DMI and hay waste. Statistical significance was set at P &lt; 0.05. Alfalfa cultivar did not impact any of the response variables (P &gt; 0.05). At feeding, round bales wrapped in net wrap had greater (P &lt; 0.015) moisture content (16.4%) compared with those wrapped with B-Wrap (12.8%). Neutral detergent fiber was lower (P = 0.03) in bales wrapped in B-Wrap (46%) compared with twine-tied bales (49%) while net wrapped bales were not different. Total digestible nutrients (P = 0.02), and relative feed value (P = 0.04) were lower in twine-tied bales compared with B-Wrap while net wrapped bales were not different. Twine (7.1 × 106 colony forming units [CFU]/g) and net wrap (4.7 × 106 CFU/g) bales had greater (P &lt; 0.0001) mold counts than B-Wrap bales (4.8 × 104 CFU/g), while concentrations of other forage components and yeast counts were not different among wrap types (P &gt; 0.05). Total DMI, and DMI during the first 24 h, were greater (P ≤ 0.032) for B-Wrap bales compared to twine-tied bales indicating preference for hay wrapped in B-Wrap; net wrapped bales were not different. Dry matter intake in the first 24 h was negatively associated with the mold count (r = −0.52; P = 0.02), and hay waste was not affected by wrap type (P &gt; 0.05). These results confirm that wrap type affected forage quality and mold counts, which in turn influenced beef cattle preference of round bales stored outdoors.

The Impact

The intercropping of ryegrass and red clover constitutes a sustainable alternative to mitigate the adverse effects of intensive livestock production on grassland degradation by increasing forage yield and quality. The implementation of biofertilization technologies has been widely used to improve soil nutritional properties, and therefore has the potential to ensure the success of this multicrop system. To determine the impact of bioaugmentation on forage growth and quality, as well as the associate changes in the rhizosphere bacterial community, we evaluated the inoculation with two plant growth-promoting bacteria (PGPB) under reduced nitrogen usage. Overall, Herbaspirillum sp. AP21 had a larger effect than Azospirillum brasilense D7 on plant growth. Inoculation with Herbaspirillum sp. AP21 together with 50% of the required nitrogen rate increased shoot dry weight, crude protein, and shoot nitrogen content, and decreased the amount of neutral detergent fiber. PGPB inoculation changed the rhizosphere bacterial community structure, which associated with forage growth and quality. We conclude that PGPB inoculation has the potential to improve the growth of the ryegrass-red clover system, decreasing the requirements for nitrogen fertilization.

ABSTRACT: The research was conducted to determine forage yield and some quality characteristics of Hungarian vetch + triticale mixture, sowed in five different times under rainfed conditions of central Anatolia, Turkey. The mixture was sowed in the second, third and fourth week of October, and the first and the second week of November in 2017 and 2018. Depending on the sowing times, plant height (PH) of Hungarian vetch and triticale was between 46.7 and 59.4 cm, and 85.9 and 93.4 cm, respectively. Green forage yield (GFY) was between 1746.2 and 2059.4 kg da-1, dry matter yield (DMY) was between 541.0 and 707.6 kg da-1, crude protein yield (CPY) was between 80.4 and 110.3 kg da-1, digestible dry matter yield (DDMY) was between 340.8 and 453.9 kg da-1, acid detergent fiber (ADF) ratio was between 31.8 and 33.7%, neutral detergent fiber (NDF) ratio was between 44.7 and 49.5%, total digestible nutrient (TDN) was between 57.9 and 60.4% and relative feed value (RFV) was between 118.6 and 133.8. Sowing time had a significant effect (P < 0.05) on PH of triticale, while it has a very significant effect (P < 0.01) on GFY, DMY, CPY, DDMY, NDF ratios and RFV. Delaying the sowing time caused a decrease in the GFY, DMY and quality of the mixture. Results revealed that the first week of October is the most appropriate sowing time to obtain high dry matter yield with high quality under continental climate conditions of the central Anatolia.

For the past 50 yr, meadow foxtail (Alopecurus pratensis L.) has been invading native flood meadows throughout the Harney Basin in southeastern Oregon. The expansion of this grass species has been the result of its broad climatic adaptation and ability to withstand drought while thriving in saturated soil conditions for a large part of the growing season. The growth of meadow foxtail starts as soon as adequate soil moisture exists. Managing this early-maturing hay species can prove to be a challenge because soil saturation and elevated water tables make it difficult to harvest hay when forage quality and yield are maximized. The purpose of this study was to evaluate whether planned grazing would retard maturation and thus prolong forage quality. Treatments included a non-grazed control and grazing durations of 2, 4, 6, and 8 wk. Grazing was initiated in May of 1998 and 1999 on six replications of each treatment arranged in a randomized block design. Within each treatment/replication combination, ten 0.2-m2 plots were clipped to ground level at about 2-wk intervals from May to August. The samples were weighed and dried for standing crop estimation and 4 of the 10 samples were selected at random and analyzed for acid detergent fiber (ADF), neutral detergent fiber (NDF), and crude protein (CP). We found that early spring grazing decreased forage yield significantly (P ≤ 0.05). Grazing tended to slow the seasonal decline in CP. The effects of grazing on the forage fiber components, however, were inconsistent. The relatively small increase in forage quality does not appear to compensate for the large decline in hay yield (a 40% decline in the shortest grazing duration treatment). We recommend that unfertilized meadow foxtail pastures be used for either haying or grazing, but not both in a given growing season. Key words: Grazing, beef cattle, regrowth, forage yield

Abstract Drought stress is the most important limiting factor in crop plants including maize (Zea mays L.), which is the third important world crop after wheat and rice. To examine the quantity and quality of forage as well as energy and water productivity of two maize varieties to drought stress, a field experiment was carried out as a split plot based on a completely randomized block design with three replications in Isfahan, Iran, during 2017 and 2018 growing seasons. The main and sub-plots were three irrigation regimes (100%, 80, and 60% full irrigation) and two maize varieties (704 and Maxima), respectively. Data analysis showed that drought stress harmed wet and dry forage yield and energy productivity, while its effect was positive on some forage quality such as ash, neutral detergent fiber (NDF), hemicellulose free cell wall (ADF), and lignin (ADL). Based on results, drought stress of 60% full irrigation resulted in reduced wet and dry forage maize yields. In addition, drought stress affected relationships among measured traits. According to increasing dried fodder and decreasing output energy under stress conditions, early mature variety Maxima is more proper to be used under drought stress. Besides, the Maxima variety was shown to be a suitable variety due to increasing dry matter and crude protein as well as decrease ADF and ADL than the 704 variety. Article Highlights We submit an original research article entitled Effect of water stress on forage yield and quality and water and energy productivity in Maize (Zea mays L.). In this paper, we indicated regarding to impacts of climate change phenomenon throughout the world on crop production, especially in arid regions such as Iran, choosing proper variety can be one of the best candidates to provide for forage. The results of present paper have shown that the drought stress had no effect on water productivity of two maize varieties. The superiority of some forage quality traits in drought stress compared to the control in maize means that in drought conditions, maize forage can be used and increase the profitability of livestock products.
