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.

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.

Abstract Choy sum (Brassica chinensis var. parachinensis) is one of the important green leafy vegetable crops widely produced and consumed in Cambodia. Most of the farmers practically use chemical inputs to increase their choy sum’s yield, yet negatively affecting consumers’ health. Accordingly, assuring food safety and higher yield of choy sum are essential for sustainable economic growth and development in Cambodia. In this study, we aimed to investigate the quality and benefits of choy sum cultivation using good agricultural practice (GAP) over the organic farming systems in northern Cambodia; where growth rate, yield and economic efficiency of choy sum crop were assessed. Completely randomized design was employed on three treatments (non-treated control, organic method, and GAP), while classical statistical tests were used to examine the difference of quality and benefits between the treatments. As a result, cultivation technique-GAP method provided a better growth rate, yield, and economic profitability than other treatments. Thus, GAP method’s application is recommended for choy sum crop production and other potential green leafy crops. These findings provided more concrete evidence on financial benefits and quality of production of the GAP method on leafy plant growth (choy sum). Therefore, agricultural extension using GAP method would be a good technique to promote agricultural value chain, while improving food safety and livelihoods of Cambodian farmers.

Competition for limited water supplies is increasing world wide. Especially hard hit are the irrigated crop production regions, such as the Lower Rio Grande Valley and the Winter Garden areas of south Texas. To develop production techniques for reducing supplemental water needs of vegetable crops, an ancient water harvesting technique called rainfall capture was adapted to contemporary, large scale irrigated muskmelon (Cucumis melo var. reticulatus L.) production systems. The rainfall capture system developed consisted of plastic mulched miniature water catchments located on raised seed beds. This system was compared with conventional dry land and irrigated melon production. Rainfall capture resulted in 108% average yield increase over the conventional dry land technique. When compared with conventional furrow irrigation, rainfall capture increased marketable muskmelon yield as much as 5355 lb/acre (6000 kg·ha-1). As anticipated,the drip irrigation/plastic mulch system exceeded rainfall capture in total and marketable fruit yield. The results of this study suggest that rainfall capture can reduce total supplemental water use in muskmelon production. The major benefit of the rainfall capture system is believed to be in its ability to eliminate or decrease irrigation water needed to fill the soil profile before planting.
