Yam farming is considered as one of the most beneficial food in different parts of the world. This plant prefer upland and require well drained soil to grow. Most quality yam production is by silt loam and sandy loam soil, although other soil such as clay loam can also be used for yam farming.
Ideal place for growing is near forests because climate and temperature is suitable for Yam to grow. Factors such as soil condition, climate, irrigation system, and temperature play important role in yam farming.
Preparing for Yam Farming
First clear all the weed and grass so that it won’taffect the farming. The best month for planting is between February and April when there is rainy season. Once the weed is cut, loose soil one meter apart and one meter in height. You have to start pre-sprouting process three weeks before plantation.
The distance between Yam should be 1 by 1 meter at 10 Cm dept. Up to 27,778 setts are required for one hectare land. You have to plant setts before rain if field don’t need irrigation. Same distance is used for non pre sprouted setts. When you are planting setts, they should be oriented, cut surface has to face ground.
If you want to reduce soil temperature, make sure there is enough moisture and weed is cut out. Before planting, make sure to mulch the field properly, it will produce high quality final product. You can use corn stalks, coconut fronds, and other similar type of materials for mulching.
Make sure that you are not using any material that will rot easily, even if you are using, make it up to 10 cm thick so that it won’t rot in coming four months. Mulching is extremely important so that soil don’t lose moisture and there are enough nutrient for the soil. Avoid using material that decay easily, it can cause problems for you in next harvest.
A single hectare of water yam can consume as much as 17 kg phosphorous, 168 kg potassium, and 128 of nitrogen from your soil. You can judge by these characteristics that it require quite good amount of fertilizer. If it is white yam, there is not much information available nutritional needs of the soil, in most cases both type of yam has similar fertilizer requirement.
