The objective of this review was to report on advances in environmental, cultural, and physiological aspects of fleshy fruit cracking to reduce or avoid this disorder, which affects many fruit species. Cracking is a physiological disorder that limits the production and quality of fleshy fruits because it affects the exocarp and mesocarp, especially with climate change and variability. Fruit cracking is generated by external factors (agronomic and environmental) and internal factors, several of which require exhaustive study. The incidence of cracking varies widely according to climatic characteristics during fruit development, different fruit species and varieties, growth sites, and crop management. This physiological disorder is aggravated by increases in rain intensity, especially after a dry season or in areas with increased temperatures. Knowledge on causes of cracking has generated management strategies that involve genetic improvement, ecophysiological conditions, agronomic practices such as pruning, irrigation, and fertilization (mainly with Ca, Mg, B, and K), applications of plant growth regulators, and use of plastic covers, etc. For several fruit trees, these strategies are effective, but in species such as the cape gooseberry, cracking remains without a full explanation or effective management.

In Colombia, potato cultivation has significant social and economic importance for the population; however, rising input costs and low yields have led to a decline in the areas planted in the country. Biostimulants are substances or microorganisms that can enhance yield by improving the physiological processes of the plants. In Colombia, there are few studies evaluating their efficiency on potato productivity. Therefore, the aim of this research was to assess the effect of biostimulant applications on the growth and productivity of potato (Solanum tuberosum L.) variety ‘CIP 39’ under the conditions of the municipality of Paipa, Boyacá department. A completely randomized design was used, with four treatments corresponding to commercially registered biostimulants with an active hormonal ingredient, seaweed extract (SWE), or carboxylic acids, and a control. Variables such as fresh and dry weight of roots, shoots, and total biomass, leaf area index (LAI), yield by quality, and total yield were evaluated. The application of biostimulants resulted in improved physiological response of the plants. The SWE-based biostimulant exhibited a better balance in terms of fresh and dry biomass, as well as in LAI, leading to a significant increase in quality and yield. This indicates that the application of biostimulants can be an alternative to increase productivity in this production system.

Commercially grown fruit crops in the high tropical Andes zones from 1,600 to 3,200 m a.s.l. are increasingly important in the world market, mainly because they are exotic fruits, and also because they are produced by hundreds of small growers. Photosynthesis is one of the most important physiological processes involved in the production and quality of fruit crops. However, many aspects of this process are unknown in fruit species grown in the Andean highlands. This systematic review presents the main themes and advances in research on photosynthesis of Andean fruit crops. A systematic literature search was carried out in the Scopus and Web of Science databases using the RStudio Bibliometrix package tool and VOSviewer version 1.6.16 software. Research on this topic has focused on high tropical Andean countries with climatic conditions for the growth of fruit species. Notably, the research addresses themes related to the photosynthesis of Andean highland fruit crops in Brazil and Colombia. The authors cover research topics from horticulture and plant physiology to photosynthesis and leaf anatomy and acclimation, where most research literature currently focuses. In most of the analyzed fruit crops, photosynthetic parameters such as maximum photosynthesis (Amax), light compensation point, light saturation point, and apparent quantum yield are known. These are important advances in the knowledge of the fluorescence of chlorophyll a, which is mainly used as a tool to characterize the eco-physiological response of these fruit species to different environments.

The aim of the research was to evaluate the influence of agronomic biofortification of BRSMG Caravera rice on grain processing by analyzing processing yield (PY) and grain yield (GY), in addition to defining the grain classification for each treatment. The analyzed plants received treatments with NPK + foliar and/or soil fertilization from different fertilizer sources. Some treatments had higher PY values compared to the control plants. For the GY parameter, only treatments with soil fertilization using ZnSO4·7H2O and two foliar fertilizations using a Bayer Antracol-Zn® product showed higher values. There may be an influence of biofortification on rice processing depending on the treatment. The grains of the BRSMG Caravera variety did not achieve a good classification, as only the grains with the treatment of soil fertilization with ZnSO4·7H2O were classified as type 4, while the grains in other treatments were classified out of type.

In plant-plant interactions, the emission of secondary metabolites can have significant effects, potentially serving as a tool for weed management. The study of plant-derived substances offers an environmental alternative to traditional production processes. The aim of the research was to evaluate the allelopathic potential of the aqueous extract of Artemisia absinthium L. on the germination of seeds of five species: Calendula officinalis L., Taraxacum officinale L., Bidens pilosa L., Senecio vulgaris L., and Brassica juncea L. The experiment involved a factorial design with five species, five extract concentrations and five replicates, for a total of 125 experimental units (EU). The aqueous extract of A. absinthium was prepared from dried foliage at a concentration of 1/50 (w/v) and applied in varying proportions (0, 25, 50, 75, and 100%) according to the respective treatments. In each EU, 20 seeds of the corresponding species were placed and grown under controlled conditions for 21 d, during which germination was monitored. The results indicate that A. absinthium has significant potential as an inhibitor of seed germination and seedling growth in T. officinale and B. pilosa. In S. vulgaris and B. juncea, the response was highly dose-dependent. In C. officinalis, no inhibition was observed in the evaluated parameters. The results indicate that A. absinthium extract offers a sustainable alternative to weed management.

The composition of the substrates in the vegetable seedbed phase is important for subsequent transplanting. The aim of this study was to evaluate the use of dry mass of the invasive aquatic plants Pistia stratiotes L. and Eichhornia crassipes (Mart.) Solms as a substrate mixed with Red Ferralitic soil for seedbeds of tomato and pepper. To plant tomato and pepper seeds, 300 alveoli were prepared with a mixture of Red Ferralitic soil with different proportions of dry mass of P. stratiotes (0.5% and 1.0%) and E. crassipes (2.0% and 4.0%). At 28 and 40 d after sowing, 30 seedlings per treatment were selected and the average length and diameter of the stem and primary root (cm) were measured. The Dickson quality index was determined in order to select the best treatment. The average stem length was greater in seedlings treated with P. stratiotes (0.5%) and E. crassipes (2.0%) and the diameter was greater in tomato seedlings treated with P. stratiotes (1.0%) and pepper seedlings with P. stratiotes (0.5%); this showed significant differences from the rest of the treatments. The maximum length and diameter of the primary root varied between treatments for both vegetables. The best treatments for the initial growth of tomato and pepper were those when Red Ferralitic soil and dry mass of P. stratiotes (0.5% and 1.0%) and E. crassipes (2.0%) were used as a mixed substrate.

One of the most aggressive bacterial diseases in tomato crops is bacterial wilt and canker caused by Clavibacter michiganensis subsp. michiganensis (Cmm). Chemical control is questioned due to its negative effects on health and the environment. Within integrated disease management, one alternative is biocontrol with Trichoderma species. Another technique is biofumigation, which releases volatile compounds into the soil that inhibit soil-borne fungi and stimulate plant health. The aim of this study was to evaluate the potential of biofumigation and the use of Trichoderma harzianum for the control of bacterial wilt and tomato canker caused by Cmm in vitro and their effect on yields in a commercial tomato crop. The inhibition of phytopathogenic bacteria of the in vitro test and the number and weight of fruits per plant in a greenhouse were evaluated. The treatments were: tomato plants inoculated with Cmm with or without two strains of T. harzianum, alone and in combination with biofumigation. The in vitro test results showed, with both strains, no significant differences between the treatments, although the growth of Cmm was lower in the combination biofumigation and T. harzianum. One of the strains of T. harzianum (Th118) performed better than the other for yield (weight and number of fruits). However, the results do not show a synergistic effect between T. harzianum and biofumigation in the observed yield values.
