Soil populations of plant-parasitic nematodes were monitored bimonthly for 18 months in irrigated and nonirrigated corn plantings using four production systems: conventional and minimum tillage with crop residue returned and minimum tillage with 60% or 90% of previous corn crop residue removed. Populations of Meloidogyne incognita, Scutellonema brachyurum, Pratylenchus scribneri, and Paratricho...

Long-term tillage negatively affects soil aggregation, but little is known about the short-term effects of tillage. We investigated the effects of intensive tillage (moldboard plowing) and conservation tillage (chisel plowing) on aggregate breakage during tillage in a long-term study located in the semiarid Ebro river valley (NE Spain). The type of tillage resulted in different soil aggregate d...

applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...

Wilhelm, W.W., Hinze, M.R. and Gardner, C.O., 1991. Maize hybrid response to tillage under irrigated and dryland conditions. Field Crops Res., 26: 57-66. The popularity of reduced-tillage cropping systems has emphasized the need to determine if maize (Zea mays L.) developed under conventional tillage systems (moldboard plow, disk, and harrow) is readily adaptable to conservation production syst...

A simple model is developed in which the density of weed seedlings emerging in a field is related to (1) the ability of seedlings to emerge from various depths in the soil, (2) the survival of seeds at different depths, and (3) the depth of seed burial in no tillage, rotary tillage, and plow tillage. Other tillage regimes are considered by analogy. Literature is reviewed to determine biological...

Agriculture is the single biggest user of land and water in Morocco; however its performances are still low due to high rainfall variation and rates of soil productivity depletion. Increasing concerns about soil and environment quality degradation have raised the need to review existing tillage management systems and develop new systems for seed-bed preparation. Consequently, No-tillage is foun...

A series of field experiments was conducted at BARI central farm to observe the changes in soil densities, moisture retentive properties, and crop productivity as influenced by different tillage depths and cropping patterns. The tillage depth showed significant effect on wheat yield. Grain yield of wheat significantly increased from 2.86 t/ha (minimum tillage depth) to 5.33 t/ha (tillage depth ...

Adoption of sustainable tillage can protect soils from biological degradation and maintain soil quality, as compared with conventional management. This paper presents findings from a long-term tillage experiment carried out in Endocalcari-Endohypogleyic Cambisols on a sandy loam soil in Lithuania. The tillage systems were: conventional (CT), moderate (MT), and no tillage (NT). Tillage intensity...

The paper presents the results of comparative field studies tillage quality commercial and combined (for primary layer-by-layer tillage) plow bottoms in terms plowing parameters, particular, completeness crop residue incorporation density tilled soil layers. study are directed to a wider introduction technical means intoproduction that provide conditions for resource saving when performing with...

This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...
