The experiment was conducted on farmer’s field at District Lakki Marwat (NWFP) during Rabi (spring) 2007-08, in order to study the response of wheat to different soil treatments irrigated with poor quality irrigation water. The treatments including control, tillage, gypsum and sulphuric acid were applied before sowing of the wheat crop. The treatments were arranged in a randomized complete bloc...

Rapeseed as one the most crops is the basic needs of human feeding in order to produce oil. A field experiment was conducted to study the effects of different tillage system, seeding method and rates on yield and its components, as well as, seed oil percentage of rapeseed (Brassica napus L. cv. Hyola-401) during 2011-12 growing season at Rice Research Institute of Iran-Department of Ma...

The effects of dwarfing alleles (reduced height, Rht) in near isogenic lines on wheat grain quality are characterised in field experiments and related to effects on crop height, grain yield and GA-sensitivity. Alleles included those that conferred GA-insensitivity (Rht-B1b, Rht-B1c, Rht-D1b, Rht-D1c) as well as those that retained GA-sensitivity (rht(tall), Rht8, Rht8 + Ppd-D1a, Rht12). Full ch...

high intensity evaporation from the soil surface due to low air humidity and poor soil structure and organic matter are constraints of agriculture in arid and semi-arid regions of iran. regionally, maintaining plant residue with tillage management is one method to improve these conditions. in this study, for a barley-corn rotation, four barley residue management methods for standing stubble (bu...

in order to study of no-tillage, reduced tillage and conventional tillage systems on some soil physical properties, yield and some traits of wheat and chickpea, experiments were perfumed across two years in sarpolezahab’s dryland region.results of combined analysis of variance indicated that different tillage systems had significant effects (p≥0.01) on seed yield, volumetric soil moisture, bulk...

Tillage influences N fate and transport by changing soil structure, aeration, macropore continuity, plantresidue placement, and organic-matter mineralization rates. Our objective was to use 15-year N budgets to compare four primary tillage treatments for continuous corn (Zea mays L.) production on tile-drained Aquic Hapludolls (FAO: Haplic Phaeozems) in northeastern Iowa, USA. A carbon-based N ...

In order to harvest higher yield of wheat, selection of suitable sowing technologies are of great importance. The objective of the present study included evaluation of profitability of innovative sowing technologies for wheat cultivation with limited water application by partial budgeting. Different sowing technologies i.e. Bed planting, Conventional tillage and Zero tillage were evaluated with...

Bed planted wheat systems offer a new alternative for the traditional wheat producer to provide opportunities for crop rotation, more efficient use of water, and new techniques of nutrient management. This study was conducted to determine if planting winter wheat (Triticum aestivum L.) in Oklahoma on raised beds can maintain grain yields while providing more options in the cropping system. Expe...

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...
