Atualmente, o tomate é uma das culturas mais cultivadas no mundo, com o maior valor econômico, aumentando sua demanda e, assim, sua expansão, produção e comercialização. A cultura do tomate é suscetível ao ataque de patógenos com consequências devastadoras no declínio da produtividade de 50 para 100%. Por esta razão, novos métodos de produção são propostos, como o uso de porta-enxertos selvagens, que possuem alta variabilidade genética e genes responsáveis pela resistência a fungos, bactérias, vírus e nematoides. O objetivo deste trabalho foi avaliar o efeito do enxerto de cultivares comerciais de tomateiro sobre genótipos de tomateiro em produtividade e qualidade de frutos. O experimento foi organizado em delineamento inteiramente casualizado com quatro repetições. A unidade experimental consistiu em quatro plantas, espaçadas a 0,9 m entre linhas (canais), 0,30 m entre linhas duplas e 0,4 m entre plantas. Os tratamentos consistiram da combinação dos seguintes fatores: três porta-enxertos promissores (IAC391, IAC426 e LA2076), dois enxertos comerciais (Calima e Torrano), dois métodos de enxertia (fenda e inglês simples) e dois controles comerciais não enxertados. Os componentes de rendimento, teor de sólidos solúveis, porcentagem de qualidade dos frutos e peso médio dos frutos foram avaliados. O IAC391 foi o porta-enxerto mais promissor, alcançando produções semelhantes às dos controles. O método de enxertia de fenda atingiu uma taxa de sucesso de 98,3%. O enxerto comercial Torrano se destacou por alcançar os maiores rendimentos.Palavras-chave: fenda; inglês simples; Torrano; Calima; porta enxerto. ABSTRACT RESUMODevelopment, production, and quality of 'Chonto' type tomato grafted on cherry tomato introductions 1 Currently, tomato is one of the most cultivated crops worldwide, with the highest economic value, increasing its demand and, thus, its expansion, production, and trade. The tomato crop is susceptible to attack of pathogens with devastating consequences on the decline in yields from 50 to 100%. For this reason, new production methods are proposed such as grafting in wild rootstocks, which have high genetic variability and genes responsible for resistance to fungi, bacteria, viruses, and nematodes. The aim of this study was to evaluate the effect of grafting commercial tomato cultivars onto cherry tomato genotypes on yield and fruit quality. The experiment was arranged in a completely randomized design with four replications. The experimental unit consisted of four plants. spaced at 0.9 m between rows (channels), 0.30 m between double rows, and 0.4 m between plants. The treatments consisted of the combination of the following factors: three promising rootstocks (IAC391, IAC426, and LA2076), two commercial scions (Calima and Torrano), two grafting methods (cleft and splice), and two ungrafted commercial controls. Yield components, soluble solids content, percentage of fruit quality, and average fruit weight were evaluated. IAC391 was the most promising rootstock, reaching productions similar to those of th...

“…In this same study, the efficiency of conventional fertilization was evaluated versus complete fertilization with boron in 'Blue Lake Pole' green beans, carried out in the department of Valle del Cauca, reporting 8,067 kg ha -1 . According to Arbeláez et al (2016), the boron element plays an important role in the fertility of the plant at the time of leaf growth, flowering, fruit set and the seed formation process; in addition, it affects many physiological processes of the plant such as transport of sugars, synthesis and structure of the cell wall, lignification, metabolism of carbohydrates, metabolism of RNA, phenols and ascorbates, respiration and integrity of the plasmatic membrane (Kabir et al, 2015). Meanwhile, Calero et al (2020) doubled the production of the variety Blue Lake with 17,974 kg ha -1 with 3 t ha -1 of chicken manure and 1 t ha -1 of vermicompost and 16,132 kg ha -1 with 1.5 t ha -1 of chicken manure and 1 t ha -1 of vermicompost.…”

Green beans are consumed worldwide due to their healthy nutritional properties. These are an important part of the modern “Grab-and-Go” diet, along with the traditional diet. Green beans are rich in protein, vitamins, fiber, folic acid and numerous minerals. In Colombia, the production of green beans is concentrated in the eastern mountain range, where there are currently low yields due to the phytosanitary problems associated with the traditional Blue Lake variety, added to the little implementation of production strategies such as plastic mulches. Thus, four varieties of green beans with plastic mulch were technically and economically evaluated. The experimental design used was complete randomized blocks with eight treatments, resulted of factors combination of the varieties (UNAPAL Milenio, Blue Lake Pole, Blue Lake National and Blue Lake S-7) and with and without plastic mulch, with four repetitions and an experimental unit of 25 plants. Planting distances were 0.25 m between plants and 1.2 m between rows for a population density of 33,333 plants/ha. The variables evaluated were: yield components, production per plant (g) and crop yield (t ha-1). The plastic mulch (black-black) had no differential effect on the agronomic behavior of the green bean varieties in the study area. The UNAPAL Milenio variety, with 9,134 kg ha-1, reached an agronomic behavior similar to the conventional Blue Lake variety with 9,717 kg ha-1. The Blue Lake variety presented the best economic behavior with a cost-benefit ratio of 1.15 and a rate of return of 14.85%.

“…The average commercial value was US$ 0.34/kg, discriminated as follows: extra US$ 0.49/kg, first US$ 0.43/ kg, second US$ 0.26/kg, and third US$ 0.20/kg (Corabastos, 2020). Finally, the following financial indicators were calculated according to Arbelaez et al (2016): Gross and net income, direct, indirect and total production costs, unit production margin (UPM), and benefit/cost ratio (B/C R). Analysis of variance and Duncan's test were performed considering a p-value < 0.05.…”

The inclusion of more sustainable alternatives such as bacterial inoculants is a viable option for the competitiveness of vegetable crops in tropical countries such as Colombia. The economic feasibility of a bacterial suspension of G. diazotrophicus applied to the carrot crop was determined. The native isolate G. diazotrophicus GIBI029 was evaluated and the strain ATCC 49037 was used as a control. The experiment was installed in a subdivided plot design, where the plot was the bacterium G. diazotrophicus (ATCC49037 and GIBI029. The subplot was the concentration of G. diazotrophicus (88×10 6 CFU/mL and 18×10 7 CFU/mL) and, in it, the levels of nitrogen and phosphorus (0% and 100% nitrogen and phosphorus) were assorted. The average weight of the carrot (g) and the yield by quality of the consuming organ (kg/ ha) were evaluated. Through the production cycle, fixed, variable, and total costs were calculated. Benefit / cost ratios higher than 1.46 and net income up to US$ 10,817/ha were achieved. It is possible to efficiently and economically use the native isolate G. diazotrophicus GIBI029 in the search for more sustainable and competitive cultural practices.
