00:00:00 - 00:45:00

This video discusses how to improve the genetic and productive yield of yuca. The presenter explains that it is important to select the right cultivar for the desired objective, and to plant in the appropriate season. They also talk about the importance of irrigation and maintaining the crop, in order to achieve high yields.

• 00:00:00 In this video, producers and technicians apologize for a recent inconvenience, and continue discussing practices that help to improve productivity. They present another tool that is very useful, allowing for guaranteed production of yuca seeds or multiplications thereof in the use of water- or thermal-heated chambers. The importance of these tools is that they ensure each seedling receives the same amount of stimulation, resulting in higher production levels. In terms of yuca, this means that, on average, up to 30% of the seeds germinate, and those that do produce 10 or more vibrant plants on average. So far, this technique has yielded an average of 200 Cordobas (5x the value of a standard cut) per farmer, compared to the 3-4 Cordobas that would be expected without it.
• 00:05:00 This video covers how to improve the genetic and productive growth of yuca, part 2. The video explains the percentages of dry matter, starch, and sugar in yuca, and how to determine the percentage of water by using a gravity meter. After the yuca has been cleaned, the next step is to measure the dry weight of the plant's three or four fresh roots. This will give you an estimate of the total weight of the plant, including the dry weight of the roots. Next, you remove any remaining organs from the roots, such as the peduncle. The final step is to weigh the roots and calculate the percentage of water content.
• 00:10:00 In this video, a farmer explains how to measure the weight of fresh yuca roots and calculate the percentage of water content. Then, they discuss how to calculate the percentage of almidon in the roots. Finally, they explain how to measure the dry weight of the yuca and compare it to the expected yield.
• 00:15:00 The video discusses how to improve the genetic and productive yield of yuca. One example is the weight of the dry fruit in this case was 3190 kilograms (9,200 pounds). It started out in water. I weighed 0.44 kilograms (1.8 pounds) and then added 400 grams (14.7 ounces) of fish food. We then divided the weight of the fish food by the weight of the yuca in water and got 1.16. We multiplied this number by 100 to get a percentage, and then we subtracted 142 points, or 5 percent, to get the percentage of dry matter. In this case, we got 41 percent. We then calculated the same percentage for the almidón. The final number was 41.5 percent. The video then goes on to talk about another method for determining the percentage of dry matter, which is using a scale to measure the weight of dry matter at different points in the growing season. The video recommends using this method to determine the percentage of dry matter at least 7 and 10 months before the harvest. The video also talks about a tool that can be used to displace eucalyptus in areas where it is not desired, which is a navarra with a heavy support system. The
• 00:20:00 This video discusses the benefits of genetic improvement and productivity in yuca cultivation, focusing on reducing costs associated with manual harvesting. There have been studies inviting farmers to compare the productivity of yuca crops harvested by hand versus using an automatic harvester. However, results of this study showed that manual harvesting with a harvester is more efficient and produces superior yields compared to traditional harvesting methods. The blue line in the graph shows the amount of plants harvested per minute by the two methods, while the red line shows the amount of plants harvested per minute using traditional methods in comparison to the manual method using an automatic harvester. The blue line is taller indicating that manual harvesting method yields more plants per minute. The study found that the manual method using an automatic harvester yields more than traditional methods, even when taking into account the increased labor costs. This video provides an overview of the benefits of genetic improvement and productivity in yuca cultivation.
• 00:25:00 The video discusses how genetic improvement and productivity can be improved in yuca cultivation, with data from field trials. According to the presenter, 100-180 quintales per manzana is achievable with the variety variety, but this significantly changes with productivity levels. The presenter also discussed service aspects, such as disease and quality control. A key factor in productivity is a favorable condition - a very important law to consider. It depends a lot on the yuca cultivar's objective. Before defining the objective of yuca culture, cultivators ask themselves what they want the yuca to achieve. This is an important question to ask, as it determines the cultivar's potential. Once cultivars have been selected based on their objective, the next step is to determine the season for sowing. This is based on a cultivar's maturity, fertility, and climate. Once the season has been determined, the cultivar's genetic potential needs to be known in order to make the appropriate seed selections. There are three main steps to yuca cultivation: selecting a planting site, seeding, and watering. After seeding, the next step is to provide irrigation to the yuca. Maintaining a yuca crop is important in order to achieve high yields, and the presenter
• 00:30:00 According to the video, the relationship between a girl and her plants is directly related to the plant's feelings of growth. We defined earlier, in Part 1, the segments where growth takes place and how to cut the wood to produce our people here is the most trivial part. It is necessary to select and classify the plants by size of the load, because observed in the diagram, titled "Parts of the stem that is the base, the middle, and the terminal," this generates more action in relation to the yields and, if we are multiplying seeds and are sowing in the terminal part, what we are doing is contributing to the regeneration of our variety emotion of our variety consists of turning it by each cycle that is carried out this variety will be unproductive, even if we do many practices that we do many fertilizers, many pesticides, cross with many inputs, etc. This is very important. To select and classify the parts according to studies, it is observed that, with the parts, it is enough to obtain the highest yields. The middle part stands out as it is a thinner part, what is done is contribute to lowering the yields. Seleccionar y destacar que provienen del aporte basal y de la parte
• 00:35:00 In this video, the effectiveness of different activities is explained, and the cost of each is mentioned. The cost of improved yields goes towards better tree trunk development, which will lead to increased production. There are a series of herbicides that are both pre- and post-plant, and have been registered here. The water continues to be efficiently used, and can control any type of blight. This example is of Asiatic cotton, and thanks to the politone product, it is very effective. There are other products that are more specific to certain crops, such as Coyolito and children, and intermediate crops. This product, called Lujo Sin Gato de Amonio, is specific for intermediate crops. It has a broad spectrum, and is contact-selective, meaning that care must be taken when using these products. Considering what needs to be taken into account when using these products- such as weed density, color, and depth of soil- it is important to note that effective use of these products requires good judgement. There are also specific products for certain types of action, such as for planting and seeding, that are not general-purpose. This is a summary of specific products that are available in Nicaragua, and is not
• 00:40:00 In the second part of this video, the importance of genetic improvement and productivity in yuca cultivation is discussed. It is strongly rooted to the ground and has greater strength. It is strongly recommended that {legalization of greater effort} be decriminalized. In terms of inclined plants should be reintegrated into the final stage whenever possible, depending on the type of soil. Especially, it is important to say that depending on the type of soil, setting stakes at a semi-inclined position that is 20 degrees above the ground and 45 degrees will result in greater yield. Genetic improvement in yuca production also faciliates harvesting of the crop in those soils where they are more scattered, suggesting this type of descent as the best method for planting straight canoes in those surroundings. Sowing methods should be discussed in detail in another video, but for now, we will look at spacing between plants and surf. Spacing between plants is typically 2 meters, but when spaced at 1.2 meters, yield is much higher. Water availability is also an important factor when it comes
• 00:45:00 In this video, the effects of genetic improvement and productivity in yuca are discussed. 45-65 days after planting, this is the period during which the plant's material dryness takes place. At this point, if we have the opportunity, we can use nitrogen again, in the form of urea, or a product formulated with potassium without its component, potassium. In this case, immediate use of potassium or double 060 is recommended. After six months, especially, fertilizer has a significant effect on the percentage of starch in the plant. For example, when we see that thousands of fertilizations are low for in vitro culture and potassium, yields are close to 200 quintals per manzana, but when fertilizations are high, the term "tonnage" translated to "300-400 quintals per manzana," the nutritional content means that when there are so many yields in tons, at around 30 tons around 400-600 quintals per form. More than all, this is what made this video. I here finished the presentation. Now it is your turn to ask questions and someone has a strong suggestion or question, we could address it now.
