Once a food crop, Tapioca has now transformed into raw material for industries, in the form of starch, livestock feed, and sago. Since Tapioca’s root system constitutes its commercial importance, soil-water management is critical to the yield of the tapioca crop.
Precision irrigation helps in several ways. The foremost is through the maintenance of the right moisture levels at the desired depth. As a result, soil compaction/ harness could be nullified. This leads to improved root development in the soil and eventually results in an increment in the tuber yield as well. Secondly, precision irrigation is fundamentally based on supplying precise or the right quantities of nutrients and water to the crop root zone. This leads to minimized crop duration, and also in an improvement in the quality of the tuber. Moreover, precision irrigation can curb the number of pest and disease attacks, coupled up with reduced labour costs, and therefore investments.
Why drip irrigation is better alternative for tapioca cultivation, despite the other cheaper methods available around?
Drip irrigation helps maintain the required moisture levels to the desired depth, in accordance with the daily water requirements of the crop. This results in minimized soil compaction and hardness. All these factors are critical to the crop root, as they determine the commercial value of the crop. Alongside these factors, as opposed to the other conventional irrigation systems, drip irrigation supplies nutrients and water directly to the crop root zone throughout their life cycle. This technique has got multiple positive impacts on the crop. It reduces weed and labour costs, improves the quality of the crop, minimizes crop deficiency and also prevents various harmful diseases that affect crop growth and quality.
Could fertilizers be applied through drip system?
Drip irrigation is a modern irrigation system that simplifies farming, and also improves the quality of the crop yield. It works as a tool for the effective application of nutrients to the plants through fertigation. Drip irrigation is designed in a way that it allows the supply of fertilizers to the plant and that too in the required quantities. However, with the only condition that the fertilizers must be completely soluble in water!
What kind of a dripper discharge is suitable for tapioca?
Low volume drip irrigation is a better alternative when it comes to offering a better wetting front in the soil, as compared to high drip irrigation. Tapioca tube yield is dependent on the wetting pattern of the soil. Low volume drippers refer to less than 2 liters per hour. This is lesser as compared to the high volume drippers which mean more than 3 liters per hour.
