Belowground microorganisms are known to influence plants' performance by altering the soil environment. Plant pathogens such as cyanide-producing strains of the rhizobacterium Pseudomonas may show strong host-plant selectivity. We analyzed interactions between different host plants and Pseudomonas strains and tested if these can be linked to the cyanide sensitivity of host plants, the cyanide p...

Field experiments were conducted during 2017 and 2018 to evaluate the efficacy of herbicides NICOSULFURON and EPTC alone or in combination with seed priming on weed control and corn yield. NICOSULFURON (80 g a.i. ha‒1) was applied at four- to six-leaf stage of corn as post-emergence and EPTC (4920 g a.i. ha‒1) applied as pre-plant incorporation (PPI). Among the herbicide treatments, the lowest ...

in this study, the performance of different cultivation methods on sugar beet fields was evaluated. eight treatments were considered: a) use of a rolling cultivator twice during the growing season; b) use of a rolling cultivator three times during the growing season; c) use of a crescent cultivator twice during the growing season; d) use of a crescent cultivator three times during the growing s...

abstract recent interest in describing the spatial distribution patterns of weeds through using interpolation methods has increased to estimate weed seedling density from spatially refferenced data and evaluation of applicable to site-specific weed management. in this research, a multi layer perceptron neural network (mlpnn) model was developed to predict the spatial distribution of h. glaucum ...

Good management models for postemergence weed control require good estimates of which weed density produces an economic threshold yield. Because intraweed competition increases if weeds are aggregated, weed spatial pattern may be an important factor for inclusion in management models. Mathematical models of weed–crop competition have demonstrated that this may be the case, but the small number ...

Background: The EU-project Flourish intends to establish an autonomously operating precision farming system based on the interaction between unmanned ground vehicles (UGVs) and unmanned aerial vehicles (UAVs). For effective mission planning and site-specific ground intervention by the UGV, the growth, mineral nutrition, weed, and health status of the crop field must be evaluated efficiently. In...

sowing date is the most important factor in physiological and morphological characteristics with positive effects on plants. to evaluate the effect of sowing date and weed interference on yield and yield components of red beans cultivars a factorial split plot experiment in randomized complete block design with three replications was carried out in the research field of zanjan university. main ...

This paper describes a dynamic simulation model that allows for comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli complex) in Philippine rice farming systems. The main outputs of the model include weed seed and plant densities and seasonal and annualised profit over the simulated planning horizon. Results broadly in...
