“…These results were in agreement with those reported by Pasqualotto et al (2015). The N rates or the interaction of N rates and dehydration conditions did not significantly affect ADF; however, a decreasing trend was observed with the N rate, which was in accordance with the results reported by Sohm et al (2014).…”

“…Sohm et al (2014) suggested that DM and CP of forages are directly related to the N rate and harvest frequency. It was found that the DM of the first crop (dry period; average daily precipitation, 9.3 mm) was lower than that of the second crop (wet period; average daily precipitation, 17.1 mm), because the increased moisture in combination with N fertilization improved the forage yield.…”

“…In tropical areas, Cynodon species is recognized as a valuable forage resource with great versatility that responds to the continuous increase in N applied to the soil, increasing the production of DM per hectare and the percentage of crude protein (CP) (Sohm et al, 2014).…”

“…Both NDF and ADF usually decrease with increasing N rate, but increase during the summer because of the relatively high temperature that promotes cellular aging, and thus, the formation of fibrous tissues (Sohm et al, 2014;Sanches et al, 2017). The nutritional potential of forage is determined by ADF that is composed of lignin (LIG) and modifies the DM digestibility as well as by the nutritional value.…”

The objective of this study was to evaluate Cynodon species 'Tifton 85' at different hay production phases (harvest, baling, and storage) and different (N) rates. Dehydration of the first crop was carried out in the field, while the second crop was in the shed. Dry matter and protein content increased linearly with the N rates. Dehydration in the shed was not effective for hay production, since dry matter did not reach the desired level of 850 g kg -1. During the hay production period (harvest, baling, and storage), the content of acid detergent fiber of the first crop and the second crop increased by 25.32 and 7.38%, respectively, and that of lignin increased by 21.33 and 32.27%, respectively. Forage digestibility decreased by 4.55%, when dehydration occurred in the field, whereas it decreased by 14.68% when dehydration occurred in the shed, a difference higher than 300% due to the loss of soluble carbohydrates. Overall, the findings of this study indicate that forage dehydration for hay production needs to be carried out in the field under appropriate environmental conditions to prevent nutritional losses. Additionally, dry matter of Tifton 85 increased by 20.40% and protein content increased by 18.65%, which equals 514.27 kg of soybean meal at 100 kg ha -1 of N.

Teff grass increases summer forage availability in the Rolling Plains of Texas

Teff [Eragrostis tef (Zucc.) Trotter] grass has gained popularity in the United States as an emergency summer forage for livestock due to its drought tolerance and rapid growth habit. An alternative forage would benefit Texas Rolling Plains growers due to the summer forage shortage caused by drought conditions. However, among the teff research conducted in the United States, there is great variability in the forage yields and nutritive values depending on the amount of nitrogen and available water. The objective of the study was to evaluate forage productivity and nutritive value of teff in the Texas Rolling Plains under irrigated and dryland conditions with two nitrogen rates and application timings. Nitrogen fertilizer treatments included single applications of either 50 or 100 lb a−1 applied at planting and a split application of either 50 or 100 lb a−1 applied both at planting and after the first harvest. No differences were observed among nitrogen rates and application methods in the irrigated trial (5286 lb a−1). The split application of 100 lb a−1 produced the greatest total yield in the dryland trial (3096 lb a−1) with no yield advantage of 100 lb N a−1 over 50 lb N a−1 at the first cutting. Forage nutritive values were similar to the warm‐season forage species utilized in the region. This study showed that teff can be an alternative forage species in the region. Future research will include planting dates, nitrogen application timing, cutting height, and the interaction of these factors on yield and nutritive values of teff.

Enhanced efficiency nitrogen formulations for bermudagrass–white clover pastures

Nitrogen fertilizer use is generally restricted in bermudagrass [Cynodon dactylon (L.) Pers.]–white clover (Trifolium repens L.) forage systems because it stimulates grass growth and increases competition with the clover, compromising forage nutritive value and prospective forage accumulation. Enhanced efficiency fertilizer nitrogen (N) products hold potential to improve white clover persistence in bermudagrass–clover pastures while providing supplemental N required by the grass. This study evaluated the effect of different enhanced efficiency N formulations (Environmentally Smart Nitrogen [ESN]; methylene urea; SuperU; and 75% ESN, 25% urea blend) and untreated urea on forage accumulation, nutritive value, and legume persistence in a ‘Wrangler’ bermudagrass and ‘Durana’ white clover mixture. Nitrogen was applied at four rates (0, 112, 224, and 448 kg N ha−1) in two equal applications each year. By the second year, white clover stands were lesser at the greatest N rates. All enhanced efficiency N sources maintained white clover similar to the unfertilized grass–clover control, but only ESN improved white clover persistence over urea. Total season forage accumulation increased linearly with increasing N rates within all three growing seasons, but dry weather conditions in the last 2 yr resulted in less forage accumulation. Nutritive value decreased with maturity throughout the growing season, but ESN maintained clover in the pasture resulted in overall less fiber components and greater digestibility. Although there was no effect of N source on forage accumulation, the ability of ESN to maintain clover could make it a viable option for fertilization in bermudagrass–white clover mixtures.
