Abstract:

The possibility of sweet sorghum cultivation with different inter-row distances (20, 50, 75 cm) was verified in small scale plots with 3 cultivars (Bovital, Goliath, Sucrosorgho). The maize cv. Atletico (rows 75 cm) was used as a control. The influence of row width and cultivar on fresh and dry biomass, methane and biogas production per area was statistically significant. The methane and biogas production was evaluated in laboratory, via fermentation in Oxi Top Control Merck bottles. Generally, sorghum was more productive than maize. The highest biogas production per hectare was found in case

Abstract:

Crop wet biomass measuring with dielectric spectroscopy is a non-destructive method to quickly and accurately estimate plant biomass in situ. It optimizes the management of agronomists. An electrostatic free-space system was designed and tested to estimate crop wet biomass in situ. It acts as a parallel plate capacitor. The appropriate size of plate of the system is determined through Finite element analysis (FEA). Water is used to make the exclusion of interference at the earlier stage of the experiment, and Wheat is the experiment material. Results from the measuring system showed The Suscep

Abstract:

Organic farming relies heavily on tillage for weed management, however, intensive soil disturbance can have detrimental impacts on soil quality. Cover crop-based rotational tillage (CCBRT), a practice that reduces the need for tillage and cultivation through the creation of cover crop mulches, has emerged as an alternative weed management practice in organic cropping systems. In this study, CCBRT systems using cereal rye and triticale grain species are evaluated with organic soybean directly seeded into a rolled cover crop. Cover crop biomass, weed biomass, and soybean yields were evaluated to

AbstractCover crop residue can act as a mulch that will suppress weeds, but as the residue degrades, weed suppression diminishes. Biomass of cover crop residue is positively correlated to weed suppression, but little research is available regarding the composition of cover crop residue and its effect on weed suppression. Field experiments were conducted to determine the impact of cover crop residue properties (i.e., total carbon, total nitrogen, lignin, cellulose, and hemicellulose) on summer annual weed suppression and cash crop yield.

This research quantifies the partitioning between vegetative and reproductive (including ear quality) components for field-grown sweet corn crops, with a range of total biomass yield resulting from different rates of P fertiliser.

Hence, this study evaluated the ability of multispectral, hyperspectral, 3D point cloud, and machine learning techniques to improve estimation of biomass and grain yield of wheat genotypes grown on a moderately sodic (MS) and highly sodic (HS) soil

Abstract:

<div>Important climatic factor affecting growth of potato crop other than temperature is the availability of solar energi. Growth of the crop can be predicted from the amount of intercepted solar radiation by crop canopy, however, climatological station only measures incoming solar radiation above crop canopy (Qo). This experiment aims to derive parameter of canopy extinction coefficient (k) that is required to calculate intercepted radiation based on Qo; and parameter of radiation-use efficiency (ε) to calculate crop biomass based on that intercepted radiation.

Abstract:

Growing a cover crop living mulch between plastic-mulched beds may reduce soil erosion while providing other agroecosystem services. However, information regarding the relative differences among living mulch species to maximize services and minimize competition for nutrients and water in adjacent plastic-mulched beds is limited. A 2-year experiment in Michigan evaluated nine living mulch species for biomass production, in-season weed suppression, and potential for cash crop competition. Species included three warm season grasses {Italian ryegrass [Lolium perenne L. ssp. multiflorum (Lam.) Husn

Cover crops are gaining in popularity as an eco-friendly tool for weed control in organic and low-input agricultural systems. A 5-year study was carried out in a Mediterranean environment (Sicily, south Italy) to (1) quantify cover crop biomass production and (2) evaluate the effects on weed soil seed bank, aboveground biomass, species richness, species composition and associations between communities. Cover crop treatments included subterranean clover (Trifolium subterraneum L.) and spontaneous flora, both with and without burying dead mulch into the soil, compared to a conventional managemen

Abstract:

Production of biomass feedstock crops could produce substantial environmental benefits, but these will be sharply reduced if these crops become invasive. Switchgrass (Panicum virgatum L.) is being bred for biomass production; these selective efforts may enhance invasive traits. To inform the assessment of invasive risk, undomesticated switchgrass strains were used as a baseline for comparison with strains bred for biomass production. In a three-year field experiment, we compared juvenile plant densities and survival, persistence of established plants, and aboveground biomass between selectivel

Abstract:

Accurate information about the amount of standing biomass is important in pasture management for monitoring forage growth patterns, minimizing the risk of overgrazing, and ensuring the necessary feed requirements of livestock. The morphological features of plants, like crop height and density, have been proven to be prominent predictors of crop yield. The objective of this study was to evaluate the effectiveness of stereovision-based crop height and vegetation coverage measurements in predicting the aboveground biomass yield of bermudagrass (Cynodon dactylon) in a pasture.

Intercropping with functionally diverse crops can reduce the availability of resources that could otherwise be used by weeds. An experiment was conducted across 6 site-years in New York and Maryland in 2013 and 2014 to examine the effects of functional diversity and crop species richness on weed suppression. We compared four annual crop species that differed in stature and nitrogen acquisition traits: (1) pearl millet, (2) sorghum sudangrass, (3) cowpea, and (4) sunn hemp. Crops were seeded in monoculture and in three- and four-species mixtures using a replacement design in which monoculture s

Abstract:

Crop biomass is an important attribute to consider in relation to site-specific nitrogen (N) management as critical N levels in plants vary depending on crop biomass. Whilst LiDAR technology has been used extensively in small plot-based phenomics studies, large-scale crop scanning has not yet been reported for cereal crops. A LiDAR sensing system was implemented to map a commercial 64-ha wheat paddock to assess the spatial variability of crop biomass. A proximal active reflectance sensor providing spectral indices and estimates of crop height was used as a comparison for the LiDAR system. Plan

An experiment was conducted in free air carbon dioxide enrichment facility (FACE) ring to study the impact of increased CO2 level on growth and biomass partitioning in mungbean crop. The crop was grown under ambient (400 μmol mol-1) and elevated CO2 concentration (550 μmol mol-1) with 5 doses of P with and without cyanobacterial inoculation. Elevated CO2 significantly increased biomass accumulation in mungbean crop which was further increased by P and cyanobacteria application.
