Studies related to tomato productivity regarding the relationship between the elimination of flower clusters and their economic sustainability are scarce. The present study was conducted in order to evaluate the effect of the number of bunches on the yield, quality and profitability of the Torrano® hybrid tomato crop under semi-controlled conditions in greenhouses of 12m x 40m (480 m2) for a total area of 960 m2. This was carried out in the Tesorito farm, property of the University of Caldas, Manizales under a design of complete blocks at random with four cut: 6; 8 and 10 bunches / plant and without cut with indeterminate growth, each treatment had six repetitions and the experimental unit was five plants. The quality of the fruit and the yield per plant and per hectare were evaluated. The plants without pruning with indeterminate growth showed the highest values in the different qualities of the fruit like first, second, third and the total yield with values of 2236, 1666, 750 and 6883 g / plant respectively. Equally, genre higher net income with $ 27,241 has / cycle, however in percentage terms quality increases as the number of bunches per plant is reduced. Therefore, it is concluded that clusters should not be pruned in Torrano® hybrid tomato under semicontrolled conditions in the study area. [ABSTRACT FROM AUTHOR]

Strawberry production is predominantly carried out in open fields, rendering it vulnerable to pest attacks, which can lead to reductions in yield. This susceptibility is further exacerbated by adverse climatic conditions. Another challenge is the high cost of inputs like fertilizers. Consequently, the aim of this study was to evaluate both technically and economically the impact of applying bacterial bio-fertilizers to strawberry crops under two production systems. The experimental design employed was a subdivided-plot arrangement in a randomized complete block, with the main plot focusing on the production system (either open field or macrotunnel), the subplot on plastic mulch (either with or without), and the sub-subplot on bacterial consortia treatments. These were as follows: (a) control, which corresponded to traditional farmer management; (b) Bacillus subtilis, (c) consortium 1, comprising a mixture of humic acids and Rhodopseudomonas palustris, Bacillus subtilis, Bacillus amyloliquefaciens, Bacillus licheniformis; and (d) consortium 2, composed of Azospirillum brasilense, Azotobacter chroococcum, Lactobacillus acidophillus, Saccharomyces cerevisiae. The combination of macrotunnel production and plastic mulch, along with the application of bacterial consortium 2, yielded the best results in the second year, producing gross and net yields of 25.041 kg ha-1 and 17.330 kg ha-1, respectively. This was associated with the most favorable benefit-cost ratio of 1.41 in the second year. [ABSTRACT FROM AUTHOR]

The cultivation of papaya is mainly managed based on the traditional knowledge of the farmers, because the research in physiological aspects is scarce and there is no scientific information about the effect of the early pruning in the flowering. Pruning of lateral shoots usually takes place between 55 and 70 days after transplantation, when the first floral bud emerges, losing photoasimilates in the shoots in the first few days after the transplant. The aim of the study was to evaluate the effect of early pruning at the beginning of flowering of the Tainung 1 papaya. The study was carried out in the municipality of Caicedonia (Valle del Cauca). Planting distances were 2.5 m between furrows and 2 m between plants, treatments were with and without stripping. The experimental design was completely randomized. The experimental unit consisted of 20 plants, with four replicates. The variables evaluated were the height of the first floral bud, stem diameter, plant height, number of leaves and time of appearance of the first floral bud. The variables height of the appearance of the first floral bud, the time elapsed for the appearance of the first bud and height of the plant presented highly significant differences (p<0.05) when the pruning was performed early. Obtaining a better behavior of the papaya with pruning, with reduction of the variables in the time of appearance of the flower buds (precocity), and height of the plant, which favors the process of production of the crop.

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 the controls. The cleft grafting method, reached a success rate of 98.3%. The commercial scion Torrano stood out for achieving the highest yields. [ABSTRACT FROM AUTHOR]
