Abstract:

The mixed crop–livestock farming systems of semiarid tropical Kenya are characterised by low livestock feed supply. The contribution of lablab and velvet bean to fodder production in a maize production system was investigated in the eastern region of Kenya. The experiment was run in three cycles, where each cycle consisted of a short legume fallow phase of ~6 months, followed by a maize-cropping phase. At the end of the fallow phase, the legume herbage was incorporated in soil at three levels; 0, 50 and 100% of total DM yield and maize planted. Maize yield from the legume fallow plots was comp

Direct-drilled wheat after long and short herbicide fallows yielded as well as wheat after cultivated fallow, and differed only in terms of small reductions (averaging 12%) in early plant growth. Non-fallow direct-drill crops had, compared with fallow crops, significantly less soil water (34 mm) and mineral nitrogen (30 kg/ha) at sowing in the first season, but not in later ones.

A study was conducted from 1993 to 1997 in a grey, self-mulching Vertosol in the central-west of New South Wales to characterise soil properties under long-fallow cotton with a view to identifying soil factors other than AM that could contribute to cotton growth

AbstractDicamba-resistant (DR) kochia is an increasing concern for growers in the US Great Plains, including Kansas. Greenhouse and field experiments (Garden City and Tribune, KS, in the 2014 to 2015 growing season) were conducted to characterize the dicamba resistance levels in two recently evolved DR kochia accessions collected from fallow fields (wheat–sorghum–fallow rotation) near Hays, KS, and to determine the effectiveness of various PRE herbicide tank mixtures applied in fall or spring prior to the fallow year. Dicamba dose–response studies indicated that the KS-110 and KS-113 accession

Abstract:

Increasing atmospheric CO2 concentrations, largely due to burning of fossil fuels, may accentuate the risk of global warming. Scientists are optimistic that with appropriate management soils can function as sinks for C and contribute to CO2 abatement strategies. The objective of this study was to determine if soil C can be increased using an annual legume green manure (GM) as partial fallow replacement in a fallow-wheat (Triticum aestivum L.)-wheat (F-W-W) rotation in the Brown soil zone of Saskatchewan. In 1995 and 1996 we measured soil C fluxes in all phases of F-W-W and GM-W-W rotations, wh

Our objective was to determine if cultivar ranking for grain yield, grain protein concentration, and kernel weight changed for hard red spring wheat in WF compared with continuous wheat (WW) systems. Ten cultivars were seeded on a Dark Brown Chernozem loam following fallow and wheat over 3 consecutive years at Dick

Traps were left in the field for 12 months and then transported to a greenhouse where they were kept for 12 additional months. Seed content was determined by field and greenhouse emergence of seedlings. The pasture was dominated by grasses, the most abundant being Poa pratensis, S
