In Morocco, cereal production is below the expected potential. The adoption of best agricultural practices that reduce vulnerability to climate a major requirement. No-tillage (NT) agriculture system could improve by enhancing soil fertility. Some factors, in combination with no-tillage, can further yields, especially choice variety adequate fertilization. objective our study investigate effect...

This study examines the effects of tillage, residue management and cropping system intensification through the inclusion of green gram on the performance of the rice-wheat (RW) system in NW India. We hypothesized that zero tillage (ZT) with residue retention provides a means of sustainably intensifying the RW system through lower production costs and higher economic profitability, whilst at the...

The soil degradation caused by conventional tillage in rain-fed areas of northwest China is known to reduce the water-use efficiency and crop yield because of reduced soil porosity and the decreased availability of soil water and nutrients. Thus, we investigated the effects of straw incorporation on soil aggregates with different straw incorporation rates in semiarid areas of southern Ningxia f...

Wilhelm, W.W., Schepers, J.S., Mielke, L.N., Doran, J.W., Ellis, J.R. and Stroup, W.W., 1987. Dryland maize development and yield resulting from tillage and nitrogen fertilization practices. Soil Tillage Res., 10: 167-179. Conservation tillage ( 7 30% residue cover) has proven to be very effective in reducing runoff and erosion and in increasing soil water storage. In dryland cropping situation...

Comprehensive assessment of the total greenhouse gas (GHG) budget of reduced tillage agricultural systems must consider emissions of nitrous oxide (N2O) and methane (CH4), each of which have higher global warming potentials than carbon dioxide (CO2). Tillage intensity may also impact nitric oxide (NO) emissions, which can have various environmental and agronomic impacts. In 2003 and 2004, we us...

A field experiment was conducted to evaluate the effect of cotton residue incorporation with conservation tillage and integrated nutrient management practices on Bt (Gossypium hirsutum L.) at AICRP Dryland Agriculture farm, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during kharif 2021-22. Fifteen treatment combinations consisting three (conventional tillage, reduced zero tillage) fiv...

In line with sustainable agriculture development, an experiment was conducted including tillage as the main factor in two conventional systems (plowing and mixing fertilizer with soil) and no tillage (leaving residuals of green manure and direct corn sowing). The fertilizer resources were T0: control, T1: barley green manure without chemical and manure fertilizers, T2: barley green manure with ...

Background: The loss of carbon (C) from agricultural soils has been, in part, attributed to tillage, a common prac‐ tice providing a number of benefits to farmers. The promotion of less intensive tillage practices and no tillage (NT) (the absence of mechanical soil disturbance) aims to mitigate negative impacts on soil quality and to preserve soil organic carbon (SOC). Several reviews and meta‐...
