in order to evaluate the effects of intercropping of maize- peanut, weeding and their planting design on weed population dynamics, an experiment was conducted as a factorial experiment in the form of rcbd with three replications at the research farm of agriculture center of zabol university (iran) in 2012. the treatments including sowing system in four levels as first factor (sole maize, sole ...
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 ...
The Formosan red-bellied tree squirrel (Callosciurus erythraeus.) is a pest animal that causes serious damage to many conifer plantations in Taiwan. Poisoning has been the major means to control the damage. The feasibility of forestry control through habitat manipulation has been evaluated during the past 5 years. The objective of this study was to investigate the effects of forest-tending oper...
the actual mechanics of performing this activity vary widely and is the cause of much concern in libraries. Furthermore, the actual decision process for selecting an item to be culled from the primary collection is not fixed, and varies according to the type of library under study and/or to the mandate of the library. Thus, the approach to weeding taken by a small public library has an outcome ...
Till now, herbicide seems to be a cost effective tool from an agronomic view point to control weeds. But long term efficacy and sustainability issues are the driving forces behind the reconsideration of herbicide dependent weed management strategy in rice. This demands reappearance of physical and cultural management options combined with judicious herbicide application in a more comprehensive ...
An assessment of the oil palm plantation management and fruit supply, under the Indian contract-growers scheme was conducted in this study. Data was collected from about 96 plantations on the age of plantation, size of plantation, cost of establishment, maintenance practices and cost , yield of fresh fruit bunches, profitability of the scheme for the farmers and so on. It was observed that most...
Tradescantia fluminensis, commonly referred to as ‘tradescantia’, is an invasive weed of canopydepleted forest remnants. Previous research suggests that a reduction of tradescantia biomass to ~80 gm-2 (~40% cover) is compatible with native forest regeneration. I assessed herbicide application, hand weeding and artificial shading as methods for the control of tradescantia in two lowland podocarp...
One of the most important agriculture operations is to properly manage weeds. Weed management a tedious task. If weeds aren't effectively controlled, it will negatively affect crop output, quality, and harvest costs. To grow successful crop, weed frequently requires significant resource inputs. Review discussion inter-row intra-row mechanical weeding, two different control techniques. In partic...
in order to compare different weed management methods in sugar beet, an experiment was conducted at the agricultural research station, ferdowsi university of mashhad, iran, during 2006-2007 and 2007-2008. the experiment designed as a complete randomized block with three replications. the treatments including: metamitron + fenmedifam, metamitron + fenmedifam + rotation, metamitron + cultivation,...
