Special Issue Information

Dear Colleagues,

In the agricultural sector, and more specifically in crop production systems, there is a huge potential for bioenergy production by green and/or yellow biomass sources. In the past, productivity was the only factor regarding crop yield evaluation. More recently, it has become obvious that crops should be assessed not only under the scope of crop productivity but also from a sustainability point of view.

Biomass energy crops and other yellow-based biomass sources (e.g., corn stover, wheat straw) have become of high interest in recent years around the globe based on their high potential as possible bioenergy production resources. The promotion of the use of biomass crop sources for bioenergy and bioproducts can be an important step to increase the sustainability of their production chain.

This Special Issue will focus on “Challenges and Advances in Sustainable Biomass Crop Production”. We invite authors to contribute to this Special Issue with novel research articles and reviews covering all topics in crop biomass production. Topics of particular interest for this issue concern the sustainable use of natural resources, environmentally friendly fertilization, water-saving methods, sustainable agronomic practices and modeling, crop physiology, energy consumption evaluation, life cycle analysis, climatic adaptation, biomass for energy, and bioproduct quality. Articles concerning all aspects of agronomic management, field operations management, and the adoption of new technologies applied to biomass crop production are welcome. We also welcome any potential article that is related to advances(i.e. information and communications technologies, automation systems and contol, agricultural robotics, UAVs, etc.) in any type of biomass crop-based production toward a more sustainable future.

Papers submitted to this Special Issue will be subject to peer review to allow a rapid dissemination of results.

Biotechnological methods prevent the destruction of natural populations of medicinal plants due to climate change and developing agriculture. This study evaluates the effects of in vitro pretreatment with two types of silver-containing amino acid nanofibers (NF-1%Ag and NF1-Ag salt) on the drought tolerance of ex vitro soil-adapted Steviia rebaudiana Bertoni. The duration of the drought was five days. The data suggested that the pretreatment with the studied nanofibers during plant propagation enhanced the plant tolerance to drought stress manifested in a smaller decrease in plant biomass accumulation and a smaller increase in sugar content. The pretreatment with the two tested nanoparticles of well-watered plants increased the leaf fresh biomass accumulation of the ex vitro-adapted S. rebaudiana compared to the untreated WW control plants. The highest values were reported at 10 mg L−1 NF1-Ag salt. Five days of drought led to a decrease in the leaf fresh biomass compared to the WW plants, with the recorded lowest reduction again at 10 mg L−1 NF1-Ag salt. These observations correlate with antioxidant activity improvement. The results show that adding 10 mg L−1 NF1-Ag salt to the MS medium led to higher ex vitro-adapted S. rebaudiana resistance to water deficit than 100 mg L−1. This paper discusses the impact of the selected nanofibers on parameters characterizing plant growth and antioxidant activity of drought-stressed ex vitro-adapted Stevia rebaudiana plants.

The objective was to evaluate the agronomic and production characteristics and the quality of forage sorghum for silage production, using a moisture-retaining polymer (MRP) in the soil during the agricultural off-season. To assess the agronomic characteristics of the forage sorghum, four treatments were used, represented by the MRP hydration intervals (Control, 0, 5, and 10 days) and four replications. The qualitative characteristics of the silage were evaluated in a 4 × 2 factorial scheme, and the same MRP hydration intervals were used for the agronomic assessment, with and without the concentrate mixture at the time of ensiling, both in a randomized block design. There were differences (p < 0.05) for all morphological variables, agronomic variables, and weight constituents of forage sorghum. There was an interaction effect (p < 0.05) between the MRP hydration intervals and the concentrate mixture at the time of ensiling for gas losses, silage dry matter recovery, and ether extract. There was an effect (p < 0.05) due to the addition of the concentrate mixture at the time of ensiling for in vitro dry matter digestibility and total digestible nutrients. When using MRP at planting and the concentrate mixture at the time of forage sorghum ensiling, a hydration interval of every 5 days is recommended. Full article

Agriculture has historically relied on fossil fuels as the primary source of energy, leading to significant greenhouse gas (GHG) emissions and exacerbating climate change. Brazil, as the third-largest producer and exporter of agricultural goods globally, plays a pivotal role in the transformation towards more sustainable practices. To this end, we propose a methodology to estimate CO2 equivalent (CO2-eq) emissions in agriculture, leveraging previous research on energy use in 23 crops in Brazil. The methodology aims to facilitate the comparison of emissions across different crops and production systems. Indirect emissions account for 36% of the total, while direct emissions account for 64%. Most direct emissions are due to the consumption of fertilizers and pesticides. The average emission per mass of product was 749.53 kg CO2-eq Mg−1, with cotton having the highest emissions and eucalyptus having the lowest emissions per product. The results highlight the importance of assessing GHG emissions from crops to identify emission reduction opportunities and promoting more sustainable agricultural practices. The study’s findings can inform policy recommendations and contribute to the development of sustainable agriculture practices globally, ultimately leading to a more environmentally friendly and economically viable agricultural sector.

Olive oil production is among the most significant pillars of crop production, especially in the Mediterranean region. The management risks undertaken throughout the olive oil production chain can be minimized using smart tools and applications. This review addressed the influence of the fruit fly of Bactrocera oleae (B. oleae) or Dacus oleae on the quality and antioxidant activity of the olives and their products based on the most recent literature data. Furthermore, in this review, we focused on the latest research achievements in remote sensor systems, features, and monitoring algorithms applied to remotely monitor plant diseases and pests, which are summarized here. Thus, this paper illustrates how precision agriculture technologies can be used to help agricultural decision-makers and to monitor problems associated with integrated pest management for crops and livestock, achieving agricultural sustainability. Moreover, challenges and potential future perspectives for the widespread adoption of these innovative technologies are discussed. Full article
