The influence of agronomical and chemical weed control on weeds of corn

Journal of Plant Protection Research, 2022
Weeds in sweet corn reduce the yield and are economically more harmful than other pests. The aim of this study was to evaluate the effects of mechanical weed control and efficacy of pre- and postemergence applied herbicides in sweet corn, and their ...

Efficacy of Various Mechanical Weeding Methods—Single and in Combination—In Terms of Different Field Conditions and Weed Densities

Agronomy, 2021
Public awareness and environmental policies have increased interest in applying non-herbicide weed control methods in conventional farming systems. Even though mechanical weed control has been used for centuries in agricultural practice, continuous ...

Effects of Weed Control and Fertilization on Wood and Chemi-mechanical Pulp Properties of a Populus deltoides Clone

BioResources, 2013
Weed control and fertilization usually lead to an increase in the growth rate of trees and, consequently, to a possible modification of the quality of the wood and its end products.

Effects of Tertill^® Weeding Robot on Weed Abundance and Diversity

Agronomy, 2022
Robotic weed control may reduce labor requirements, soil disturbance, and amount of herbicide applied relative to non-robotic methods. Tertill® is among the first weeding robots to become commercially available. This solar-powered robot moves in a random

Parasitic Plant–Host Interactions: Molecular Mechanisms and Agricultural Resistance Strategies

Advanced Science, EarlyView.
Parasitic plants devastate global agriculture through sophisticated molecular interactions with host crops. This review synthesizes current understanding of parasitic plant‐host interactions, from strigolactone‐mediated germination and haustorium formation to host defense mechanisms.

The influence of mechanical weed control and manual hoeing on plot weed infestation and maize yield

Glasnik Zaštite Bilja, 2023
An experiment with different variants of weed control in the maize crop was carried out in 2021 at a location next to the Markovo Polje settlement on silty loam soil. Three variants of weed control were applied: 1.

Temperature and Farm Labor in Nigeria

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Weed management and its relation to yield and seed physiological potential in common bean cultivars

Pesquisa Agropecuária Tropical, 2013
Common bean is an important crop in Brazil primarily because of its nutritional characteristics. Some agronomic practices, such as weed management, are fundamental to cultivation, as a means of obtaining a high crop yield.
