Abstract Weeds occurred during the fallow season can well perform the function of carbon (C) capture due to receiving little human disturbance. This study aimed to evaluate the C capture potential of fallow weeds in rice (Oryza sativa L.) cropping systems. A six-region, two-year on-farm investigation and a three-year tillage experiment were conducted to estimate C capture in fallow weeds in rice cropping systems. The on-farm investigation showed that the average mean C capture by fallow weeds across six regions and two years reached 112 g m^–2. The tillage experiment indicated that no-tillage practices increased C capture by fallow weeds by… More >

Abstract Parthenium poses serious threat to modern crop production system and necessitate evaluating control practices for its effective management. Efficacy of different weed control practices for controlling parthenium was explored in conventional and deep tillage systems in the field conditions. Hand hoeing (20 and 35 days after emergence), S-Metolachlor (pre-emergence herbicide), sorghum straw mulch @ 5 tons ha^-1 and combination of hand hoeing and sorghum straw mulch (hand hoeing at 20 and straw mulch at 35 days after emergence) were used as weed control practice. Weedy check where no weed control measure was applied was also included in this experiment for… More >

Abstract Public demand for healthier foods and more sustainable food systems in the U.S. has triggered market prices and production of organic alternatives of major crops such as corn (Zea mays L.). Two cover crops and their interactions with tillage systems, N sources and N rates were studied to evaluate the possibility of using these agronomic practices to facilitate growing corn under organic management in Kentucky. A split-split plot design in a RCBD with four replications was evaluated in three environments (SP08, UKR08, UKR09). The main plot treatments were cover crops [hairy vetch, HV (Vicia villosa Roth) and rye (Secale cereale… More >

Abstract In the present study the effects of three tillage systems: conventional (CT), vertical (VT) and direct drilling (DD) on three bread wheat varieties of different cycle length, were studied, for yield and yield components. Their influence on grain quality, expressed through thousand kernel weight (TKW, g), test weight (TW, kg/hL), grain protein content (GPC, %) and yellowberry percentage (YBP, %) were also studied. The highest average yield was under CT and DD, while the lowest was under VT. The lowest dry matter accumulation and one third fewer spikes per unit area were determined under VT. Concerning grain quality, a comparatively… More >

Abstract Plant yield and oil content determine sunflower production. Those plant production determinants depend in turn on the plant–environment interaction. In the South West of France, there have been recent advances in soil tillage. To date, 35% of the soil surface dedicated to sunflower is cropped under a reduced tillage system. Major constraints to sunflower cropping are water stress and cryptogamic diseases. The second most important sunflower disease in the South West of France is premature ripening caused by Phoma macdonaldii. Aims of this work were to: 1) understand how these factors influence sunflower yield, and 2) quantify the fatty acid… More >

Abstract Tillage system is an important management decision that has to be taken in the central, semiarid, temperate region of Argentina for dryland wheat production. A 2-year study was conducted on an Entic Haplustoll soil with a sandy loam texture to determine the effects of three tillage systems (conventional, vertical and notillage) on leaf water status and chlorophyll content. Measurements were made at the Z65 growth stage with a SPAD-502; leaf water potential measurements were simultaneously taken. There was a positive relationship between leaf water potential and leaf greenness in both years. Tillage systems were significantly different in 2007; both variables… More >

Abstract About 15% of the world surface is subjected to the effect of man activities. The main causes of land surface degradation are livestock production, deforestation and inadequate agricultural practices. In Mexico, little attention has been given to soil conservation as a non-renewable natural resource. This has been mainly degraded by excessive use of agricultural machinery. As a result, 64% of the national territory suffers some degree of deterioration. Comarca Lagunera, located between Coahuila and Durango states in Mexico, is the main milk production region. In this region, 900000 t of cow manure are produced annually. This amount of cow manure… More >

Abstract Soil compaction represents an important issue in the actual context of agricultural system sustainability. Research on the various developments of root systems under tillage has been explored for many crops, whether for the biomass area or the underground, but very little concerns Sunflower (Helianthus annuus L.). The objectives of the study were to understand the impact of soil tillage and of the induced mechanically compacted soil on: i) sunflower’s root system architecture, ii) biomass area iii) production. Two complementary experiments were realized in the south of France (France’s main sunflower production area). In both experiments, increased resistance of the soil… More >
