Effect of organic crop rotations on long-term development of the weed seedbank [PDF]
, 2002 Changes in the weed seedbank were monitored between 1991 and 1998 in two experiments that were established to compare organic crop rotations at two sites in NE Scotland.

Irrigation and Drainage, EarlyView.ABSTRACT Soybean growth, yield, crop evapotranspiration (ETc) and crop water use efficiency (CWUE or crop water productivity, CWP) under different irrigation levels in three different soil types in the same field were investigated concurrently. Treatments in each soil type were: (i) variable rate irrigation (VRI), (ii) fixed rate full irrigation (FR‐1″)

Allelopathic effects and weed suppressive ability of cover crops
Plant, Soil and Environment, 2016 Field and laboratory experiments were conducted to investigate the weed suppressing effects of cover crops in single and mixed cultivation. Weed densities in the field experiments ranged from 0 to 267 plants/m2 with Chenopodium album L., Matricaria ...

EDIS, 1969 Beets can be found as red beets, table beets or garden beets. Both the tops (greens) and the bottoms (swollen hypocotyle) may be eaten. Always check the label on beet greens because residue establishment varies. Clopyralid (Stinger) has just received labeling for use postermergence, over-the-top of beets. At the present time however, Stinger may not be

Irrigation and Drainage, EarlyView.ABSTRACT This research investigated soybean soil water dynamics under different irrigation levels in three different soil types in the same field concurrently. Treatments imposed in each soil type were: (i) variable‐rate irrigation (VRI), (ii) fixed‐rate full irrigation (FRI‐1″ or FRI‐25.4 mm) and (iii) fixed‐rate limited irrigation (FRI‐0.75″ or FRI ...

Development of weeds in organic crop rotation experiments [PDF]
, 2005 Weeds are a major problem in organic farming. Preventive as well as curative measures must be utilised to manage the weeds and avoid proliferation. Besides direct weed control measures, many different aspects of planning and management in the cropping ...

Development and Testing of a Low‐Cost Soil Moisture Sensor for Real‐Time Irrigation Scheduling
Irrigation and Drainage, EarlyView.ABSTRACT Effective irrigation scheduling is essential for improved water management in irrigated areas, with soil moisture monitoring recognized as one of the most effective methods. However, challenges such as the high cost of sensors and the difficulties in monitoring large areas hinder their practical application, particularly for smallholder ...
