Uncontrolled weeds cause considerable losses in the grain yield of pigeonpea. Field experiments were conducted for seven years from 1998 to 2004 on a loamy sand soil to study the effect of weed management on weeds, growth and grain yield of pigeonpea. In some years, weed dry matter was higher than in others, due to variation in rainfall received. Two hand weedings, pendimethalin in integration ...

this experiment was carried out at the research farm of faculty of agriculture, university of zanjan in spring of 2012 to introduce an integrated weed management method in fennel. treatments were type of herbicide (trifluralin and pendimethalin), application dose (recommend dose in other crop (r), 75 percent r, 50 percent r, and 0 percent r) and supplemental control (none, one hand-weeding at 5...

The present study was conducted at Collage of Agricultural Engineering Sciences University Duhok (Sumel) and Zakho Research Center (Zakho), Kurdistan Region, Iraq, during the growing season 2021-2022 to investigate effect different factors includes broad bean cultivars (Aguadulce & Lunga Delle Cascine), herbicide treatments (Control, Basagran 300mL.100L-1, Gallant super 375mL.100L-1, + Hand...

to assess the effect of non chemical management of weed control on forage sorghum (sorghum bicolor) a field study was conducted in varamin, iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (w1= one time cultivation at 3-leaf stage using a duck foot cultivator, w2= two times cultivation at 3 and 5-...

In Bangladesh during 2017-2018 was conducted in a farmer's field of the Chattogram hill districts to determine effectiveness different weed control strategies for transplanted chilli. The dry weight weeds, efficiency, index, and yield components like number fruits per plant, fruit length, weight, marketable yield, had been significantly affected by using measures. act treatment chilli fields, h...

BACKGROUND The prevalence of different biotic processes (limiting similarity, weaker competitor exclusion) and historical contingency due to priority effects are in the focus of ongoing discussions about community assembly and non-random functional trait distributions. METHODOLOGY/PRINCIPAL FINDINGS We experimentally manipulated assembly history in a grassland biodiversity experiment (Jena Ex...

1.17 The drudgery of weeding is so ingrained into the lives of farmers in developing countries that weeds are taken for granted and often overlooked in pest surveys. And yet weeding by hand, typically carried out by women and children, accounts for 50% of the total labour inputs needed to produce a crop, deprives millions of children the joys of playtime – and often schooling – and adds to the ...

the present study evaluated the effects of different dosages herbicides oxyfluorfen and trifluralin on crop properties of garlic, including plant height, number of cloves per bulbs as well as economical and biological yield of garlic. in this research, a randomized complete block design, with seven treatments and three replications, along with a control sample (weeding and no weed control), was...
