Adaptation of diffused light storage system for potato under mid-elevated condition
2000
Anon.
The study aimed to determine the efficiency of the DLS [diffused light storage] technology in comparison to the existing farmers storage practices in the mid-elevated areas which is generally a makeshift dark storage (DS) usually attached to or part of the farmers' houses. The first storage trial was conducted for 6 months during the period January to June 2000. Both the DLS and DS were loaded each with 750 kgs, Granola variety seed materials, which is the predominant variety in the area. Sprouting was observed to be faster inside the DLS wherein the seeds are ready for planting after 4 months of storage compared to the 6 months storage period in the DS. Sprouting percentage is also higher at 63 percent as compared to the 49 percent of the seeds in DS, this means increased planting materials for the farmers. As per the physical characteristics of the sprouts, DLS yields shorter (with an average of 1.1 cm length) and thicker (ave. of 0.63 cm) and dark green sprouts, which according to the cooperator makes them sturdier and easier to transplant as compared to the quality of the seeds stored in DS. Rotting incidence begins to be visible after 2 months of storage for both set-ups. Final estimate of the percentage of rotten tubers before it was planted is at 16 percent and 28 percent for DLS and DS, respectively. However, there was no significant observation of disease and pest infestation for both storages but the cooperator found it easy to monitor these parameters for seeds stored in DLS. Also, emergence of plants is faster by two weeks for seeds stored in DLS as compared to those stored in DS. With these initial findings, the technology supports the significant findings, experiences and viewpoints of its user in the highland
