Crop Residue Management for Sustenance of Natural Resources and Agriculture Productivity

Pacific Agriculture and Natural Resources

Coffee can be cultivated under various management schemes from heavy shade to full sun. Higher yields are generally achieved in full sun but often at the expense of smaller beans and greater requirements for water and nutrients. We compared growth, yield, bean size, and total value in a coffee agroecosystem in Hawaii grown in full sun or at two shade levels (30 and 50%) under Leucaena variety K...

There is a need to select high quality forage legumes that are acid soil-tolerant, drought resistant, and persistent under the close defoliation associated with intensive pasture systems in the humid tropics. A greenhouse pot study was conducted to determine forage legume seedling growth (10 week-old) and regrowth (5 weeks after clipping to an 8-cm residual stubble) responses of ‘Amarillo’ pere...

Tradeoffs in Crop Residue Utilization in Mixed Crop-Livestock Systems and Implications for Conservation Agriculture and Sustainable Land Management

Evaluation of Tillage, Nitrogen Fertilizer and Crop Residue Management on some Agronomic Traits of Soybean

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Unmanned aerial systems for agriculture and natural resources

remote sensing tool for scientific research in the late 1970s. However, due to a variety of limitations (the weight and limited functionality of available sensors and cameras, the lack of GPS-guided autopilots and so on) these platforms had few practical applications (Przybilla and Wester-Ebbinghaus 1979; WesterEbbinghaus 1980; cited by Colomina and Molina 2014). For years, UAS technology was l...
