A field experiment was conducted during rainy (kharif) seasons of 2020 and 2021 at the research farm ICAR-Indian Agricultural Research Institute, New Delhi to study effect nutrient weed management on crop productivity soil microbial properties in aerobic rice (Oryza sativa L.). Experiment factorial randomized complete block design replicated thrice. Nutrient factor comprised 3 levels, viz. Cont...

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 ...

in order to examine of the weed damage on corn and determination of the most suitable index for corn (zea mays l.) yield reduction in field condition and multi-species weed competition, an experiment as an interval mapping was carried out in the researching field of mashhad university during 2008-2009. treatments were complete control (pre-planting treflan and hand weeding), no control (no herb...

The study was carried out at Lamahi-8, Satbariya, Dang to evaluate the effect of different weed management practices on production spring maize. experiment in a Randomized Complete Block Design using three replications and seven treatments. Rampur hybrid 10 variety early post emergence (EPoE) herbicide were used experiment. treatment consisted single as well combined methods T1: Broadcasting-On...

Even when considered a modern cultivation system, silvopastoral systems can be rapidly degraded if some cares, mainly related to weed control, are not observed at the early stages of establishment this system. The present work had objective evaluating use forage legumes on suppression and initial development Teak (Tectona grandis) implementing Four legume species were used, namely: pinto peanut...

In Europe, Rumex obtusifolius L. is the most problematic grassland weed species, especially under the conditions of organic farming. The aims of this study were (1) to investigate the effectiveness of repeated mechanical weeding of R. obtusifolius from the permanent sward, cut two or three times per year, by digging the plants out from 5 cm below the soil surface, and (2) to test the effect of ...

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 ...
