Abstract


These researches have aimed to know about the concentration and giving of blocked essence in mepiquat chloride toward growth and the result of potatoes (Solanum tuberosum L.). In addition, its have influence toward growth of the result potatoes.
The hypothesis from this study is there are interaction between given of concentration with giving of blocked essence mepiquat chloride to potatoes. Moreover, the concentration and giving of blocked essence mepiquat chloride will give growth and the result well.
Farmer?s field in Junggo - Malang, had done this study from January up to May 2002. Which is use split plot design in frame of group random. The concentration of blocked essence can be placed as particular partition and giving of blocked essence that has placed as sub-partition.
The observation toward the growth parameter can start 25 HST for age, with 6 of plant samples. In addition, the next observation will be done with time interval 10 days once. While the observation to the result, parameter would be done for the guest period with 8 samples plant. The growth parameters can involve such as plant high (cm), amount of leaves, stem diameter (cm) and wide of leaves to each plant (cm2). While to the result parameter can included amount of tuber each plant, weight of tuber each plant (g), weight of each tuber 9g), the result of guest (t/ha) and class percentage of tuber (%).
The processing and data analysis that have use is frame of group random split plot. The data processing can included, like data construction, raw data (primer data) and statistics. After the data have obtained of each parameter and observation interval, so its will continued with account of variety analysis with BNJ test ( Tukey test). This test has based on the value group that have different from size and it depends on the distances of two middle values that have compared. If there is interaction between both of factors, it will continue with regression.
The result of this analysis can shown that vegetative phase to plant high, amount of leaves, wide of leaves is not influence, but for the diameter stem to concentration of blocked essence mepiquat chloride 4ml/1 each of partition that given 40 hst, give high value. For the generative phase to tuber per plant, weight per tuber, the result of guest is not influence. While weight of tuber per plant have influence to concentration of concentration of blocked essence mepiquat chloride 10mlo/1, class percentage of tuber 30g ? 60g have influence for 6 ml/1 and percentage tuber class 30g have influence at giving blocked essence mepiquat chloride 60 hst. By using blocked essence, mepiquat chloride is well, because it can increase the result of potatoes if it is compared from the research previously.
