Nebraska, US, is projected to face increased winter and spring precipitation, drier summers as the climate changes over next 20 30 years. Agricultural adaptations adjustments would be critical mitigate adverse impact of change achieve global food security. Focusing on climatic projections for our objective analyze data from a long-term (31 years; 1986–2016) rainfed agriculture experiment determ...

Beneficial effects of leaving residue at the soil surface are well documented for steep lands, but not for flat lands that are drained with surface inlets and tile lines. This study quantified the effects of tillage and nutrient source on tile line and surface inlet water quality under continuous corn (Zea mays L.) from relatively flat lands (<3%). Tillage treatments were either fall chisel or ...

Prefix 10.18034 This performance evaluation was conducted to pave the way for making use of Draught Animal Power Cultivator and cosequently possibilities of adaptation in our local condition between 2010 and 2011 in the Jimma zone two districts of southwestern Ethiopia on the farmers’ field to evaluate energy requirement. To improve weed management at the small holder farmers level, animal-draw...

INTRODUCTION In an extensive review of organic mulches applied on conventionally tilled (plow-disk) fields, Dutton (1957) concluded: 1) that organic mulches such ashay and straw often increasedboth yield and quality of Irish potato (Solanum tuberosum L.) and 2 ) that improved soil physical properties under the mulch, particularly lower soil temperatures and conservation of soil moisture, were r...

Dryland farming in the Mediterranean climate of the Pacific Northwest, USA supports extremely low earthworm populations under conventional tillage. Increases in earthworm populations are being observed in fields under no-till cropping systems. A 30+ year experiment with four tillage levels in a pea (Pisum sativum L.)-winter wheat (Triticum aestivum L.) rotation was evaluated for earthworm popul...

one of the basic adjustments in application of agricultural implements, particularly tillage tools, is their work in a leveled state while in operation. throughout the ongoing research, and by application of electronic and hydraulic circuits, an intelligent system was designed, developed and evaluated. the device is expected to perform the plow longitudinal as well as lateral adjustments at the...

background and importance: disk sequestration can be defined as a herniated disk with perforation of the fibrous ring (or outermost annulus fibrosus) and posterior longitudinal ligament with migration of the disk fragment to the epidural space. even after the introduction of high-resolution magnetic resonance imaging (mri), it is still frequently misinterpreted as neoplastic masses. unfortunate...
