since wheat-rice cropping system is down in about 50000 hectare of khoozestan province and also necessity of optimum land and water utilization, this study was condulted during one year (2008-2009) in shawoor agricultural research station to compare different conservation tillage system with traditional system for wheat cultivation in paddy residue. experiment conducted in randomized complete b...

in order to evaluate the effects of foliar application of methanol and irrigation intervals on yield and yield components of chickpea cultivars a factorial experiment as split plots based on randomized complete block design with three replications was conducted in spring 2008 at the agricultural research station of ferdowsi university of mashhad. the treatments were 10 and 20 irrigation interva...

Blowing dust from summer fallow is a major soil loss and air quality concern in winter wheat (Triricum aesrivum L.) production areas of the inland Pacific Northwest (PNW). The objective of our 3-yr onfarm study in a 286-mm precipitation zone in eastern Washington was to determine the effects of tillage mulch depth during fallow on surface soil roughness, residue retention, seed-zone water stora...

in order to study the effects of conventional and conservation tillage with management residue on wheat physiological properties, a field experiment was conducted in 2013-2014 at mashhad agricultural and natural resources research center of razavi khorasan province. this experiment was carried out as split plot design based on a randomized complete block design with three replications. main plo...

The combination of isotope trace technique and SOC fractionation allows a better understanding of SOC dynamics. A five-year tillage experiment consisting of no-tillage (NT) and mouldboard plough (MP) was used to study the changes in particle-size SOC fractions and corresponding δ (13)C natural abundance to assess SOC turnover in the 0-20 cm layer of black soils under tillage practices. Compared...

The New Crops Program of Virginia State University, established in 1991, has evaluated the production feasibility of a wide array of leguminous crops including chickpea, faba bean, mungbean, and pigeonpea under Virginia’s agro-climatic conditions (Bhardwaj et al. 1996). Such crops could provide alternatives to farmers in Virginia and adjoining Mid-Atlantic States. These farmers, in general, rel...

A field experiment was conducted to evaluate the yield and chemical composition of triticalegrain in different crop rotation and tillage systems. The first experimental factor was thecropping system – a) crop rotation and b) monoculture and the second factor was the tillagesystem – 1) conventional (CT), 2) reduced (RT) and 3) no-tillage (NT). The spring triticale yieldwas found to be 15.4% high...

Objective: Drought stress is most important factor which reduce root and shoot growth in crops. This study was performed in order to evaluate the effects of drought stress and Zn fertilizer on root traits of four cultivars of chickpea. Methods: Experiment was laid out in a split plot-factorial using randomized complete block design with three replications. Drought stress treatment stand in main...
