Best Fertiliser For Yam

Yam is a staple crop in many countries around the world. It has been cultivated for thousands of years and is still widely used today. Yams are a great source of nutrients, including B vitamins, fiber, potassium, and vitamin C.

They grow best in warm climates with plenty of sunlight. They can be grown in pots indoors or outdoors. They can also be grown in raised beds if you live in an area where they may not do well outside due to cold weather or other factors.

Yams are best planted in spring or summer when temperatures are consistently above 60 degrees F (16 degrees C). The ideal soil temperature for yams is between 70-80 degrees F (21-27 degrees C).

The best fertilizer for yam is composted manure mixed with soil at a ratio of 3 parts composted manure to 1 part soil by volume. This will provide your yams with all the nutrients needed to thrive during their growing season.

Best Fertiliser For Yam

You can grow yams in a variety of ways. You can choose to use the traditional NPK fertilizers, a Biofertiliser that contains NPK, or you can also use a mix of all three. NPK fertilizers are best for yams because they provide the right balance of nutrients for the plant to grow healthy and strong. However, it is important to remember that you should also consider using manure or biofertilizer if possible.


The optimum fertilizer rate for yam depends on the soil type and its pH level. For intensive crops, a soil study should be conducted to determine the existing nutrients in the soil. In addition, an appropriate proportion of NPK Fertiliser can be applied prior to planting to ensure the proper development of the plant. In general, the recommended amount of NPK Fertiliser for yam is 200 kg ha-1.

Soil samples should be analyzed to determine the level of nitrogen in the soil. If nitrogen is insufficient, alternative fertilizers should be applied. However, this may not be sustainable. Applying only half of the NPK Fertiliser recommended for yam may be necessary. To get the most out of your yam crop, consider using legume residues instead of nitrogen fertilizer. In this way, you can reap the benefits of legume residues and reduce costs.

Yams need a balanced ratio of nitrogen, phosphorus, and potassium for optimal growth. Nitrogen promotes leafy growth while phosphorus and potassium support root development. Potassium helps in water retention, disease resistance, and flowering. To apply the NPK Fertiliser, simply spread it on the soil with a spray bottle or band. It is recommended to use at least four to five kilograms of inorganic NPK Fertiliser per hectare of yam land.

The composition of the soil is an important factor when choosing an NPK Fertiliser for yam. A low N content and a low K content will negatively affect yam yield. Similarly, an inefficient fertilizer may have insufficient potassium and cause low yields. Insufficient K content in the soil will reduce nutrient K absorption. High potassium content in the soil will encourage the yam plant to use nitrogen in the soil.

Biofertilizers with NPK

Fertilizers are substances that help plants grow strong. Some fertilizers only contain one type of nutrient, while others may contain a mixture of different types. It is important to know the types of nutrients your yam needs and what their functions are before applying fertilizers. You can read about some of the important nutrients below. This article will explain how these nutrients work to improve yam growth and yield.

In addition to NPK fertilizer, yams benefit from organic manure to maximize nutrient availability. One hectare of yam land requires approximately four to five kilograms of NPK fertilizer. Depending on the soil, this amount may be increased or decreased. The application rate of NPK fertilizer should be determined by soil tests. A rate of 400 to 500 kilograms per hectare may be used for maximum tuber yield.

The biofertilizers with NPK are non-bulky, environment friendly, and low in cost. They may play an important role in plant nutrition. They are a type of free-living bacterium that can fix atmospheric nitrogen. During the long rain season, biofertilizers with NPK significantly outperformed NK treatments. Both types of fertilizers increased the total bacterial number and increased tuber yield.

These fertilizers can be used in a variety of soil conditions and will increase yield by 30 percent. NPF and NPK fertilizers work by providing the nutrients that plants need for photosynthesis. In addition to this, they can be used in poor soil conditions. These fertilizers contain nitrogen, phosphorus, and potassium, which each play different roles in photosynthesis. These nutrients work together to make up a balanced diet for the plants and can be beneficial even without rich soil.


The best fertilizer for yam is manure, a composted agricultural waste. This fertilizer has the highest nitrogen content of all known plant nutrients. It also contains a high percentage of phosphorus, potassium, and sulphur, which is important for the growth of yam crops. However, the best fertilizer for yam depends on the location of the planting plot. A ridge or mound will provide more space for the yam plants to grow, and this will provide optimal soil conditions for fertilizer absorption. Mounds are ideal for seeding since they are higher than the rest of the plots and will receive fertilizer at the end of the growing season.

Fertilizers are used to provide the necessary nutrients for plants to grow strong and healthy. Some fertilizers contain one type of nutrient, while others are made from a mixture of several types. You need to know what each nutrient is for and how they work together to ensure that your yam plant grows well. Once you know which nutrients are required by your yam plants, you can decide what type of fertilizer to use.

Aside from using manure, there are other methods of applying fertilizer to yams. One of them is banding, spreading, or manually applying it. In general, four to five kilograms of inorganic NPK fertilizer per hectare of land will provide adequate nitrogen and phosphorous levels for the yam crop. A combination of plant residues and NPK fertilizer is considered the best fertilizer for yam.

Combination of all three

It’s essential to use the right type of fertilizer for yam to maximize yields. Fertilizers are made of different materials, some of which contain one type of nutrient, while others are combinations of two or more. It’s important to understand which type of fertilizer you need and what their functions are before choosing the right fertilizer for yam. Listed below are the most important nutrients for yam.

Yam plants can benefit from nitrogen, phosphorus, and potassium. Researchers at the University of California, Davis, examined the effects of nitrogen and phosphorus on yam growth. They found that nitrogen and potassium had no effect on dry matter accumulation and starch content. In contrast, potassium and legume residues were beneficial to yam growth. Combined with manure or organic matter, these fertilizers may be beneficial.

The amount of nutrients released by soils largely depends on the properties of the soil. While nitrogen and potassium are essential for yam growth, a low level of fertility can cause the crop to fail to yield. Hence, farmers must use a combination of three types of fertilizer to boost yam yields. But, if these methods don’t produce the desired yield, they will be inefficient.

For optimum yield, a balanced combination of N, P, and organic matter is required. Nitrogen is essential for the development of photosynthetic apparatus, dry matter accumulation, and tuber yield. Consequently, fertilizing yams with nitrogen is imperative. However, it is important to harvest and process yams as early as possible to avoid nutrient deficiencies. In addition, a balanced mixture of nutrients is needed to maximize yield and minimize the risk of nematode infestation.

Low nitrogen fertilizers

To understand the benefits of low nitrogen fertilizers for yam, let us first look at how these nutrient levels affect the crop. The nutrient recovery is mainly explained by the amount of N that the crop can absorb. For instance, adding nitrogen to a crop’s soil can increase the yield by 12%. In one study, nitrogen fertilization increased the yield by 12%. Moreover, added nitrogen induced an increase in tuber and shoot growth. But adding potassium did not enhance yields. Adding potassium to the soil reduced dry matter production. Consequently, higher levels of potassium and magnesium in the soil reduced N and P accumulation.

To increase yam productivity, NPK fertilizer is essential for the crop. It increased vine length, leafiness, and tuber bulking. Generally, a 300 kg NPK rate per hectare of land is enough for maximum tuber yield. However, the recommended rate of NPK fertilizer varies depending on the soil test response. When applied at a 400 kg NPK rate per hectare, the plant showed increased vegetative growth, internodes, LAI, and girth. However, this fertilizer increased LAI but reduced tuberization.

To choose the best nutrient mixture for yam, you should first determine the location of your yam plants. If possible, plant them on mounds or ridges. Mounds range from 30 cm to 100 cm high. The higher position will allow for increased seeding rates and optimal conditions for the plant to absorb the fertilizer. The yams will grow to a higher position when fertilizer is applied towards the end of the growing season.

Genetic variation in yam genotypes can help farmers increase yields by enhancing tolerance to low soil fertility. A recent study assessed 21 white Guinea yam genotypes under low soil fertility conditions. The resulting tuber yields were compared to a local variety. While the results were not statistically significant, the researchers noted that some genotypes were more resistant to low soil fertility than others. Breeding and genetic studies of yam should include physiological studies.
