Study on the growth of marigold seedling in pots made from sunflower’s stem

Abstract

This article aims to study the growth of marigold sprouts which grew in seeding pots from sunflower stem which invented from after harvested sunflower stem mixed with starch and formed to be seedling container in compression molding machine. This research process consists of 3 main processes.  The first process was designing and produced seedling pots. The second process was study on the growth of marigold seedling in pots made from sunflower’s stem. And the final process was observed pot after use. The results of testing pots by planting marigolds were as follows:  1) The result of the growth of marigold grown in pots with the appropriate ratio of material between scraps of sunflower stem and starch are 90:160 100:200 110:120 และ 110:200 showed the growth of marigold sprouts better than other material ratio. 2) The results of the study on the transformation of pots by observing various characteristics, including stabilization pots, settlement pots and breakage of pots. The result was found that the material with all ratios showed abnormalities observed after 2nd week until the end of the experiment (31 days after transplanting) and the appropriate ratio of material (scraps of sunflower stem and starch) that were 90:160 and 90:180. From the results of the study, farmers can use the waste material to increase their income. and is also environmentally friendly.
