to evaluate the effect of combined use of weeds control an different mechanical methods on weeds number and dry weight in cotton , a split plot experiment based on randomized complete block design was conducted at the region of boshruyeh in 2012. experimentals factors were tillage methods as main-plots with three levels, including conventional tillage, no-till system and minimum tillage; and di...

A field experiment was carried out in 2017–2019 as a split-plot design with four replicates at the Agricultural Experimental Station Grabów, Poland. The aim of study to compare gas exchange parameters pea depending on use different soil tillage systems. Physiological plant as: net photosynthetic rate (PN), transpiration (E), stomatal conductance (gs), intercellular CO2 concentration (Ci) and re...

Best nitrogen management practices are the pre-requisite to warrant high maize yield. Thus, experiments were conducted to study the “effect of tillage and split application of nitrogen on hybrid maize” under semi-arid conditions of Pakistan, during fall 2008 and 2009. The experiments were laid out in randomized complete block design with split-plot arrangement, replicated three times in a net p...

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...
