Results & Conclusion

Warm season forages can provide favourable forage yields and have similar mineral/nutritional value as cool season forages. The inclusion of warm season forages into pasture can be beneficial as it can extend the grazing season without sacrificing pastures. From the data available it is fair to say while warm season forages didn’t greatly increase Ca, Mg, P and K levels, it did however remain within the same level as cool season forages. This maybe be due to the fact temperature was becoming milder and rainfall was increasing, warm season crops didn’t improve mineral content as one may have expected. Fluctuations in minerals were statistical significant difference mixture and mixture*month which could be due to environmental conditions, season, maturity or forage specie. The pastures tested had almost adequate levels of minerals for grazing ruminants.

The above scatter plot indicates the relationship between temperature and potassium. In the range between 17.5 and 20 degrees highest levels of K are found, however below 12 degrees and above 22.5 degrees, K levels drop greatly.

Potassium levels from April (4) to August (8) and over each of the 3 years, Blue (2017), Orange (2018), Grey (2019).
As stated there little fluctuation between each year and month

10 year temperature data. General overview the temperature follows a cyclical pattern, reaching lowest temperature in 2013, highest in 2016 and low again in 2019.

How the CCAFS legacy lives on December 16, 2021
Ambitious CGIAR reforms put climate action at the heart of its new strategy and initiatives Our global food 'system'—that is, the production, processing, transportation, consumption and (too often) the waste and loss of all food—accounts for a quarter of all greenhouse gas emissions. These emissions are second only to heavy industry in terms of their […]

AgLEDx: A new CCAFS resource for understanding low-emissions development in agriculture December 14, 2021
So what is low-emissions development? And what does it have to do with agriculture? New AgLED Resource Platform has the answers Global food systems contribute about one-third of global greenhouse gas (GHG) emissions, and agriculture accounts for over half of these emissions and is expected to nearly double by 2050. Research has shown emissions reductions […]

Evaluating bean crop management through the Olopa TeSAC December 13, 2021
A participatory research experience with farmers in the dry corridor of Guatemala Guatemala is one of the most susceptible countries in Central America to climate variation. Seven of its twenty-two departments are located in Central America’s dry corridor, where heat waves have behaved irregularly in recent years; either going on for longer than usual or […]

Nigeria to industrialize frugal tech innovation December 9, 2021
Variability in climate makes agriculture risky. In the tropics, this mostly relates to variability in rainfall. To address this, the World Meteorological Organization (WMO) recommends a minimum of 1 precipitation recording station per 5,750 km2. Nigeria, which is home to 220 million people, meets this recommendation with 176 functioning weather stations. Yet, with interest rates […]
