Influence Of Seeding Rate On Growth Performance And Yield Of Early Maturing Sorghum, Ismail S. Selemani, O. B. Ngonyani Oct 2021

Influence Of Seeding Rate On Growth Performance And Yield Of Early Maturing Sorghum, Ismail S. Selemani, O. B. Ngonyani

IGC Proceedings (1977-2023)

Heavy grazing pressure in Tanzanian semi-arid rangelands coupled with climate change and variability has resulted into severe decline in forage production and changes in vegetation composition. To increase forage biomass production in the face of climate change and variability, climate resilient fodder crops such as early maturing sorghum have been recommended in arid and semi-arid regions. However, paucity of information on the best agronomic practices especially the optimal seeding rate and row spacing fostered the need to carry out research on growth performance and yield of early maturing sorghum. The experiment was conducted at Magadu Dairy Farm to assess the …

Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair Oct 2021

Comparison Of Four Maize Cultivars (Zea Mays L.) As Winter Forage In Sudan, Rihab El Zubair

IGC Proceedings (1977-2023)

Winter forage availability in Sudan is constrained by lack of a suitable annual winter forage crop. The main forage crop grown is Abu70 (Sorghum bicolor) which is a summer crop that yields 7.6-8.4 t/ha in summer but much less in winter. There is, therefore, need for a winter high yielding forage crop that exceeds Abu70 in productivity and quality. This study was aimed to evaluate four forage maize cultivars as potential winter crops in central Sudan in terms of productivity and quality. An experiment was conducted using four maize forage cultivars. The experiment lasted for two consecutive seasons …

Moving Warm-Season Forage Bermudagrass (Cynodon Sp.) Into Temperate Regions Of North America, W. F. Anderson, L. Baxter, D. Hancock, R. N. Gates, Esteban F. Rios

IGC Proceedings (1977-2023)

Warm-season (C4) perennial grasses are grown over millions of hectares in the Southeastern United States. These grasses produce optimal growth at 30 to 38°C diurnal temperature. Bermudagrass (Cynodon sp.) has been adopted as the preferred forage for many livestock and hay producers. Compared to other native and introduced warm-season perennial grass species, improved bermudagrass varieties produce high biomass with enhanced digestibility for ruminant grazing or feed. Until the 1930’s pastures in the region consisted of unimproved ‘common’ bermudagrass (Cynodon dactylon (L.) Pers.) that had been introduced earlier. However, in the early 20th century, new germplasm, including stargrass …

Epigenetic clocks based on DNA methylation (DNAm) can accurately predict chronological age and are thought to capture biological aging. A variety of epigenetic clocks have been developed for different tissue types and age ranges, but none have focused on postnatal age prediction for preterm infants. Epigenetic estimators of biological age might be especially informative in epidemiologic studies of neonates since DNAm is highly dynamic during the neonatal period and this is a key developmental window. Additionally, markers of biological aging could be particularly important for those born preterm since they are at heightened risk of developmental impairments. We aimed to …
