In arable cropping systems, reduced or conservation tillage practices are linked with improved soil quality, C retention and higher microbial biomass, but most long-term studies rarely focus on depths greater than 15 cm nor allow comparison of microbial community responses to agricultural practices. We investigated microbial community structure in a long-term field trial (12-years, Lincoln, New...

abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...

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‐...

Universities as the places of training the experts play an essential role in social, economic and cultural structure of the nations. The quality of education and the educational space are two major effective factors on the quality of training the students. Since the educational places are of the most important land-uses in the cities, the compatibility of them with other surrounded land-uses is...

Many sustainable agronomical practices can be adopted to contain environmental risks of crop production and, at the same time, sustain yield and quality. In this framework, the aim of this research was to study the effects of continuous cropping (CC) and crop rotation, tillage and fertilization strategies on durum wheat (Triticum durum Desf.) production. The responses of soil properties we...

What is it like doing science in India? Let me make the operating rules clear before I answer. Every question about India has two ‘correct’ answers which say exactly opposite things. Furthermore, each of the one billion Indians will disagree with one another and with what any outsider has to say about India. Being a scientist in India is wonderful. Really. Every good grant proposal gets funded....

introduction phosphorus (p) is an essential element in crop nutrition, which can be growth limiting or an environmental contaminant, if present in excess. on the other hand, tillage practices have a direct effect on behavior and availability of soil p. since, application of different tillage methods lead to different patterns of soil phosphorus distribution, hence p fertilizer needs and p avail...

Limited time for crop residue decomposition and complete seedbed preparation in double-cropping necessitates reduced tillage which is associated with its shortcomings. Information about seedbed preparation aspects in double-cropping of wheat and mungbean in Isfahan is lacking. For this reason, the effects of various seedbed preparation methods on growth, seed yield and yield components of mungb...

Tillage systems and organic manures could affect soil physical and mechanical properties. This study was conducted to investigate the impacts of two tillage systems including conventional tillage by moldboard plowing (plowing depth, 30 cm) and reduced tillage by disk plow (plowing depth, 15 cm) and three rates (0, 30 and 60 ton ha-1) of farmyard manure (FYM) on the soil penetration resistance u...

The effects of tillage methods and residual management on yield and yield components of rapeseed (Brassica napus L. CV. Hyola308) were evaluated after rice harvest. The experiment was carried out during 2004-2005 cropping season in a factorical arrangement of treatments at Rice Research Institute of Iran (RRII) in Rasht, in a Complete Randomized Block Design with three replications. Treatments ...
