Fertilizers are used to help plants grow strong and healthy. They are made from a variety of different materials, such as manure or compost. Some fertilizers contain only one type of nutrient, while others may include several different types in varying amounts. In order to know how much fertilizer you should use for your yams, it’s important that you understand what types of nutrients are needed and their functions.

NPK fertilizers are some of the most popular fertilizers and are known for their ability to increase production by as much as 30%. These fertilizers work by supplying nutrients that plants need, but that may not be present in the soil. This can be especially beneficial when soil conditions are poor. The basic ingredients of NPK fertilizer are nitrogen, phosphorus, and potassium. Each of these nutrients is essential for plant health and growth, and each plays a different role in the process of photosynthesis.

Yams require nitrogen (N), phosphorus (P) and potassium (K). Nitrogen promotes leafy growth; phosphorus encourages root development; potassium helps with water retention and disease resistance. Potash also encourages flowering in certain varieties of yams like the sweet potato vine (Ipomoea batatas). All three of these nutrients are essential to a yam’s health and development.

Method of Fertilizer Application

There are several ways of applying NPK fertilizer to yam. The most common methods are spreading and banding. Per hectare of yam land, 400 to 500 kg of inorganic NPK fertilizer should be applied. Both methods are effective. Read on to find out how to apply NPK fertilizer to yam. In addition, learn about the different benefits of fertilizer to yam.

For the maximum yam yield, you should know how to apply NPK fertilizer to your crop. It will enhance the nutrient uptake and utilization of the plant. In addition, supplementary application of organic manures to fertilize the yam soil will maximize the tuber yield response. It is recommended that you apply 300 kg NPK fertilizer per hectare. The rate of NPK fertilizer depends on the soil nutrient reserves.

Nitrogen, phosphorus, and potassium (NPK) are macronutrients plants need to grow. Fertilizers supply plants with these nutrients, increasing the plants’ ability to grow and survive. This is important because a plant growing too little or too much will not produce well. Your objective is to supply your yam with macronutrients in quantities that promote growth without being excessive. In this article, we’ll go over how to apply NPK fertilizer to yam recommendations, as well as what types of fertilizer you can use as you strive toward achieving healthy plants of your own

There are several ways on how to apply NPK fertilizer to yam. One of the most popular methods involves banding and using a spreader. It can also be applied manually. In a nutshell, you need to apply 400 to 500 kg of inorganic NPK fertilizer per hectare of yam land to produce a good yield. Here are the best methods.

Before you start applying nitrogen-based fertilizer to yam, it is important to analyze soil samples to determine whether they contain adequate nitrogen levels. If they do not, then you should consider using other fertilizers instead. However, this may not be the best option for your yam. In addition, applying half of the recommended amount of NPK fertilizer may not be a sustainable solution for yam.

Moreover, adding Pueraria residues to yam plots before applying the fertilizer increased tuber yield by 15.8%. AM colonization on yam roots was enhanced when fertilizer was added to the soil. Both methods improved the organic carbon and total N content of the soil. They also increased the exchangeable Ca and Mg content of the soil. This combined application of plant residues and fertilizer improved the yield of yam. Ultimately, the use of half of the recommended NPK fertilizer may be a sustainable solution for yam production.

In a field experiment, we grew 20 advanced yam genotypes and a landrace cultivar. The experimental plots were grown under uniform conditions. The plants were harvested at 33 WAP. Weighing between one and two kilograms, tubers were visually assessed and cut horizontally to remove the head and tail components. We measured the number of tubers per plant and the corresponding relative yield to the control.

Fertilizers are applied by banding, spreading, or manually. Generally, four to five kilograms of inorganic NPK fertilizer per hectare of yam land should be applied per year. However, some growers may choose to use a combination of plant residues and NPK fertilizer for better yam yield. A combination of these two fertilizers may be the most sustainable method for your yam crop.

An experiment in southern Nigeria evaluated the effects of applying manure, mineral fertilizer, and a combination of the three. The researchers planted white Guinea yam on soil with varying mound sizes, and then applied NPK fertilizer. The results indicated that mound size was more important than fertilizer in increasing yam tuber yields. In addition, the study demonstrated that manure application had no significant effect on the amount of tuber yield, even on land that was in its second and third year of bush fallow.

Dry matter accumulation

In a field trial conducted by the University of California, Davis, researchers investigated the effect of nitrogen, phosphorus, and potassium (NPK) on starch, dry matter, and yield. They found that nitrogen had no significant effect on dry matter accumulation and starch content. However, phosphorus decreased dry matter accumulation. These results indicate that legume residues are beneficial to yam crops.

For improved yam productivity, NPK fertilizer application is important. Fertilized yam plants showed greater vine length and leafiness, which are indicators of increased tuber yield. Furthermore, NPK fertilizer increased tuber bulking. A 300 kg NPK rate per hectare of yam appears sufficient for maximum tuber yield. However, it is important to know how much NPK fertilizer to apply to your field based on the soil test response.

Using 400 kg NPK per ha-1 resulted in increased vegetative growth, shorter internodes, and longer vines. It also increased LAI and decreased tuberization. Both treatments correlated with an increase in leaf number. The results also suggest that NPK may enhance the plant’s nutrient status. The researchers concluded that higher fertilizer doses enhance plant growth and yield.

The results of this study are limited by the lack of detailed meteorological data. The researchers did not measure the extent of leaching or surface runoff of nutrient compounds from the yam tubers. They also did not quantify the amount of N and K that was returned to the soil in yam tubers. The researchers concluded that the reduced nitrogen use of the crop may be sustainable for yam production.

Starch content

To find out the relationship between NPK Fertilizer and yam starch content, we first had to understand how each component affects the starch content of yam. In this research, we used a field trial to explore the effects of NPK fertilizer on starch and dry matter content. It was found that the optimum nitrogen level was 35 kg ha-1 for forest Alfisol that had been cultivated for two years. The nitrogen level had no effect on the starch content, but decreased the dry matter accumulation.

We used three different methods of starch extraction, adapted from the Food and Agriculture Organization of the United Nations. The first method involved washing, peeling, and cutting sweet cassava into small pieces. We used distilled water for a minimum of 2 min to extract starch from the cassava. Then, we filtered the starch extract with an 80-mm mesh sieve and left it for 20 h at 25 degC.

A higher concentration of fertilizer increased urea absorption and decreased NH4NO3 adsorption. These differences were found across the three fertilizers. However, starch in cassava and potato showed the highest absorption capacity for all fertilizers studied. Furthermore, they retained more urea during the water release. The nutrient content of yam and potato also decreased with increasing crop mass, so higher concentrations of NPK fertilizer in cassava were more effective.

Similarly, a combination of NPF and NPK fertilizer increased the starch content of yam. Biofertilizers with NPK were more effective in improving sweet potato tuber yield. Biofertilizers with NPK also improved the water storage capacity of sweet potato cells. This in turn increased the sweet potato’s yield. The results are encouraging, and suggest the use of biofertilizers in fertilization and crop production.

Potassium

Potassium is an essential element for yam growth. Its level is directly related to the soil pH. Moreover, yams are sensitive to nitrogen and potassium. A balanced fertilizer for yams contains these nutrients. Potassium is the main component in fertilizer. It should be applied in the proper amounts to get the desired crop yield and growth. Using too much fertilizer may also damage the yam plant.

The results of the study showed that the agronomic efficiency of yam is influenced by its soil composition. Fertilizers with low nitrogen content have a negative impact on yam yields. Insufficient K content may also be caused by the use of inefficient fertilizers. For instance, the nutrient K is used up faster in nonfertile soils than in fertile ones. A high potassium content in soil can help the plant absorb more nitrogen.

Fertilization has been recommended as an important management strategy for yams, particularly those grown in degraded soils. A field experiment in central Cote d’Ivoire in 2006 and 2007 found that fertilization with 15N labeled fertilizer increased yields by 12%. The added N promoted the growth of tubers and shoots. However, potassium level did not enhance yields.

The optimum potassium fertilizer levels in yam were obtained at 64 kg ha-1. However, higher levels of K2O:MgO resulted in less dry matter production. On the other hand, high levels of potassium and magnesium in the soil reduced the accumulation of total N and P. The study also showed that the yam bean responded well to fertilizer levels lower than the recommended amount.

Nitrogen

Fertilizer is necessary for yam plants, and the correct amount depends on the variety. Fertilizer should contain a balance of nutrients, including nitrogen and potassium, and should not contain excessive amounts of either. Ideally, the amount of fertilizer should be 400 to 500 kilograms per hectare of yam land. Fertilizer should be applied by spreading or banding the fertilizer.

The correct fertilizer mixture will increase the yield of yam crops. In tropical areas, yams are commonly grown. Without fertilizers, the peasant environment lacks the skills to properly care for these crops. In low temperatures, the yam tubers and bad seeds dehydrate and rot. This creates a big problem in the food industry, as it results in less nutritious and attractive crops.

The optimal time to apply fertilizer to yam plants depends on their location. It is recommended that yams be planted on ridges or mounds. Mounds can range from 30 cm to 100 cm in height, providing more space to grow and optimal conditions for fertilizer absorption. Ridges, on the other hand, allow for increased seeding rates. In this way, the yams will be planted in a higher position and receive fertilizer at the end of the growing season.

Aomori Prefecture, Japan, is home to an extensive yam industry. However, the underlying soil type is poor and is prone to nitrogen leaching. Furthermore, increasing localized torrential rain caused by global warming increases the risk of nitrogen leaching. In a recent study, we investigated the behavior of nitrogen components in fast-acting and delayed-release fertilizers and compared them to the level of nitrogen leaching in the groundwater environment.

In conclusion,

Fertilizer is that thing that helps apply nutrients to land and trigger growth of yam. Many yam gardeners have been using NPK fertilizers in their gardens as it has been proven to showcase fast results and growth of beautiful yams. When you apply a fertilizer, let say NPK fertilizer, to the yam, it feeds the plant with the needed nitrogen, phosphorus and potassium (NPK) which triggers growth.

Applying NPK fertilizer to yam is what plant scientists and science students need to be able to do towards the end of the yam’s growing season and also for a continuous production of healthy yams. For this purpose, it is necessary that you first understand how NPK works as well as how to apply them properly. Most commercial yam farmers use NPK in producing yam at most times of the year and normally mix it with water using a watering can or drip at intervals of two weeks.
