Growth Promoting

Vegetable cultivation is a promising economic activity, and vegetable consumption is important for human health due to the high nutritional content of vegetables. Vegetables are rich in vitamins, minerals, dietary fiber, and several phytochemical compounds. However, the production of vegetables is insufficient to meet the demand of the ever-increasing population. Plant-growth-promoting rhizobacteria (PGPR) facilitate the growth and production of vegetable crops by acquiring nutrients, producing phytohormones, and protecting them from various detrimental effects. In this review, we highlight well-developed and cutting-edge findings focusing on the role of a PGPR-based bioinoculant formulation in enhancing vegetable crop production. We also discuss the role of PGPR in promoting vegetable crop growth and resisting the adverse effects arising from various abiotic (drought, salinity, heat, heavy metals) and biotic (fungi, bacteria, nematodes, and insect pests) stresses.

Delayed Flowering

Plants undergo profound physiological changes when transitioning from vegetative to reproductive growth. These changes affect crop production, as in the case of leafy vegetables. Lettuce is one of the most valuable leafy vegetable crops in the world. Past genetic studies have identified multiple quantitative trait loci (QTLs) that affect the timing of the floral transition in lettuce. Extensive functional molecular studies in the model organism Arabidopsis provide the opportunity to transfer knowledge to lettuce to explore the mechanisms through which genetic variations translate into changes in flowering time. In this review, we integrated results from past genetic and molecular studies for flowering time in lettuce with orthology and functional inference from Arabidopsis. This summarizes the basis for all known genetic variation underlying the phenotypic diversity of flowering time in lettuce and how the genetics of flowering time in lettuce projects onto the established pathways controlling flowering time in plants. This comprehensive overview reveals patterns across experiments as well as areas in need of further study. Our review also represents a resource for developing cultivars with delayed flowering time.

The paper defines the structural distribution of sown area of crops. The dynamics of production of cereals and legumes, sugar beets, sunflowers, potatoes, vegetables, fruits and berries. The clustering of regions of Ukraine under similar conditions of development of the enterprises of the agricultural sector specializing in crop production is carried out. According to the results of the analysis, 3 clusters were identified, which gave rise to the possibility of forming (developing) joint effective organizational and economic mechanisms to enhance the development of crop enterprises, favorable for implementation within the cluster. In the course of this study, we focus on the development trends of enterprises specializing in crop products. The lion's share (54.7 %) of sown areas falls on cereals and legumes. Technical crops occupy, which is 32.6 %, and potatoes, vegetables and melons – 6.5 %. It is important to note the long-term positive dynamics of production of cereals and legumes and the growth of production can be traced to all categories of farms – in farms and households. The production of sunflower and vegetable crops was also marked by positive dynamics. The decrease was observed in the production of sugar beets, potatoes, fruit and berry crops. In the context of the study, it is important to identify similar conditions (environment, resources, etc.) for the development of agricultural enterprises between the regions of Ukraine. For this purpose, multifactor statistical analysis (cluster analysis) of key factors of their development was used on the basis of a matrix of 25 selected indicators of development of enterprises specializing in crop production in all regions (600 indicators). To enhance the objectivity of the results, the analysis was conducted in 2010, 2015 and 2019. According to the results of the analysis, taxonomic groups (clusters) were singled out, which made it possible to single out similar regional conditions within each group. Since 2010, there have been significant changes in the regional distribution of Ukraine's agricultural potential. However, during 2015–2019 there is a relative stability in terms of resource provision and use within specific clusters. According to the results of the analysis, three clusters are distinguished: I. Volyn, Zakarpattia, Ivano-Frankivsk, Lviv, Rivne, Chernivtsi, as well as Donetsk and Luhansk regions. II. Dnipropetrovsk, Zhytomyr, Zaporizhia, Kyiv, Mykolaiv, Odesa, Ternopil, Kharkiv, Kherson, Khmelnytsky regions. III. Vinnytsia, Kirovohrad, Poltava, Sumy, Cherkasy and Chernihiv regions.

Background: The present world population is about 7.9 billion and it is increasing continuously. Thus, there is an urgent requirement to enhance the agricultural output sustainably. Agricultural approaches such as the use of advanced agriculture methods, high productivity varieties, and enhanced application of fertilizers and pesticides have significantly increased food grain production but in an unsustainable way. Chemical-based conventional fertilizers and pesticides have been found associated with environmental pollution and other unwanted effects on the ecosystem, soil quality, and soil microflora, etc. Nanomaterials may be used to replace conventional fertilizers and pesticides in agriculture. Objective: The aim of this review is to provide information about the harmful effects of chemical fertilizers and pesticides, and the use of nanomaterials in agriculture. Including this, the health risks of nanomaterials are discussed. Method: This review article includes a survey of literature from different online sources (for example, Web of Science, PubMed, and Google Scholar, etc.). Results: The improvement in agricultural output using chemical fertilizers and pesticides is considered unsustainable as it is increasing the cost of production, affecting the soil quality, disturbing nutrient availability in crops, and causing environmental pollution. Nanotechnology is a potent innovative practice and nanomaterials may be used in agriculture as nanofertilizers, nanopesticides, and nanosensors. Although these approaches have the potential to enhance agricultural productivity in a sustainable way, nanomaterials are also assumed to exhibit potential health risks to humans. Reports have indicated that nanomaterials have been found associated with many systematic diseases such as cardiovascular diseases, neurotoxicity, and toxicity to the reproductive system, etc. Conclution: It is well accepted that chemical fertilizers and pesticides in agriculture cause environmental toxicity and affect ecosystem activity. Nanomaterials have the potential to enhance agricultural output, but these are also associated with health risks. Thus, detailed scientific studies must be conducted about the potential health risk of nanomaterials before their commercial applications in agriculture.

Ecological Criteria

This chapter is concerned with a set of optimization problems associated to crop rotation scheduling in the context of vegetable crop production according to some ecological criteria: no crop of the same botanic family is planted in sequence, green manure and fallow periods must be present in any schedule. A core mathematical model called the crop rotation scheduling model is proposed to represent these ecological criteria together with specific technical constraints associated to the growing of vegetable crops. Three optimization problems based on crop rotation schedules are written in detail in this chapter. For each problem, the authors present a general modeling framework and a solution methodology based on a technique known as column generation, which iteratively builds crop rotation plans for a number of plots. Some extensions are also presented, with the aim of incorporating additional characteristics found in production field conditions. This chapter ends with a brief discussion on a set of computational experiments and some suggestions for future research.
