Meeting the future food security challenge without further sacrificing environmental integrity requires transformative changes in managing the key biophysical determinants of increasing agronomic productivity and reducing the environmental footprint. Here, we focus on Chinese rice production and quantitatively address this concern by conducting 403 on-farm trials across diverse rice farming sys...

The New Zealand deer industry is growing rapidly and the development of sustainable management practices for deer farming is becoming increasingly important. The main environmental issues facing the deer industry are the effects on soil and water quality, exacerba ted by the behaviour responses of deer to confinement (in particular fence pacing and wallowing). In addition, the projected increas...

Rainfed lowland rice production in lower Northeast Thailand is a complex and adaptive farming activity. Complexity arises from interconnections between multiple and intertwined processes, affected by harsh climatic and soil conditions, cropping practices and labor migrations. Having faced a spatially heterogeneous and dynamic environment for centuries, local rice farmers are very adaptive and a...

One of the major goals of the Sustainable Agriculture Farming initiatives at UC Davis is to provide information about the feasibility of adopting conservation tillage and cover cropping at the farm level. The project includes two tillage schemes: standard tillage (ST) and conservation tillage (CT), and three farming methods: conventional, organic, and winter legume cover crop. All three product...

This paper examines common factors that constrain wheat yields: insufficient nutrients (using nitrogen as an example); problems of late planting and poor crop establishment; suboptimal water management; lodging; and weeds. The authors suggest agronomic practices, including tillage practices, rotations, and input management options that can ameliorate important constraints and sustainably improv...

The phenolic and antioxidant activity of ethanolic extract of two Japonica rice cultivars, Taikeng no. 16 (medium and slender grain) and Kaohsiung no. 139 (short and round grain), grown under organic and conventional farming were examined. Analyses shows that Kaohsiung no. 139 contains the highest amount of secondary metabolites and continuous farming can increase its production. Results also s...
