“…Specifically, when the rate of nutrient uptake is affected by root density, the role of phosphate in the soil becomes vital in the absorption of other essential nutrients. Moreover, phosphorus also plays a key role in plant physiological processes, including photosynthesis [35,45,46].…”

Walnut anthracnose caused by Colletotrichum gloeosporioides is a deleterious disease that severely affects the production of walnut (Juglans regia L.). The aim of this study was to assess the antifungal and growth promotion activities of Bacillus velezensis CE 100 as an alternative to chemical use in walnut production. The crude enzyme from B. velezensis CE 100 exhibited chitinase, protease, and β-l,3-glucanase activity and degraded the cell wall of C. gloeosporioides, causing the inhibition of spore germination and mycelial growth by 99.3% and 33.6% at 100 µL/mL, respectively. The field application of B. velezensis CE 100 culture broth resulted in a 1.3-fold and 6.9-fold decrease in anthracnose disease severity compared to the conventional and control groups, respectively. Moreover, B. velezensis CE 100 produced indole-3-acetic acid (up to 1.4 µg/mL) and exhibited the potential for ammonium production and phosphate solubilization to enhance the availability of essential nutrients. Thus, field inoculation of B. velezensis CE 100 improved walnut root development, increased nutrient uptake, enhanced chlorophyll content, and consequently improved total biomass by 1.5-fold and 2.0-fold compared to the conventional and control groups, respectively. These results demonstrate that B. velezensis CE 100 is an effective biocontrol agent against anthracnose disease and a potential plant growth-promoting bacteria in walnut tree production.

“…Management of pests: In managed and unmanaged ecosystems, most weeds are C4 plants and respond directly to CO2 levels. The increase in CO2 levels under the future climate (now 380 ppm, Vu, 2005) may stimulate the growth of these plants and would require different management systems (Sage and Kubien, 2003). This will become common under high temperatures and reduced soil moisture conditions (Patterson, 1993).…”

Climate change is a global concern arising from spatial or temporal changes in precipitation, temperature and greenhouse gases. The impacts of this on critical climate-sensitive areas are largely on land, marine resources, forestry and agriculture, and their biodiversity and ecosystems. In Papua New Guinea (PNG), the mainstay (85%) of the rural people is on land and agriculture, compared to resources obtained from the marine areas and forest. Productivity on land depends on climatic factors and a compromised climate affects land, which in turn affects forestry, agriculture and the marine environment (resources and ecosystems). Because of this, a lot of resources have been invested in climate change to understand the impacts; however, much is yet to be achieved, especially in the developing nations. In PNG, understanding the types of changes in climate that will be experienced is important to be resilient, to mitigate and to adapt. In this review, the potential impact of global climate change on climate of PNG and the impact of the new (future) climate on land, marine and forest resources and their biodiversity and ecosystems are analyzed. Moreover, the impacts on crop agriculture are discussed. Analysis of available data shows that the temporal and spatial changes in precipitation and temperature projections of the future climate are within current optimum crop production ranges, at least up to 2090. Since most staple and plantation crops in PNG are C3 plants, an increase in CO2 levels will have a fertilizing effect on productivity. The plastic effects on certain crops may benefit some farmers as temperature, precipitation and CO2 levels change.
