Abstract

Silicon is the second most abundant in the soil and Silicon could be considered as an essential element in many crops to enhancing growth and alleviating biotic and abiotic stresses. Silicon present exclusively in the form of silicic acid (H4SiO4). It is absorbed by plants in the form of silicic acid. The aim of research is knowing the content of Chlorophyll and Abscisic Acid of soybean under drought stress by silicon application. The different levels of Silicon were tested in a pot experiment to assess their effects on chlorophyll content and Abscisic acyd on several cultivar of soybeans under drought stress. The results show that there is no interaction between each treatment cultivar and silicon. The absorbance value of chlorophyll leaf using spectrophotometer shows that chlorophyll content differs significantly on each cultivar of soybeans. The increasing application of silicon concentration tends to increase chlorophyll content but decreases the levels of Abscisic Acid (ABA) in leaves.

Abstract

Drought stress becomes a serious threat to the cultivation of soybean because it could affect the whole processes of soybean plants that may ultimately result in a significant reduction in yield. To obtain high production in drought stress conditions, one needs such efforts as including the use of utilizing high yielding varieties resistant to drought and/or designing environmental alteration engineering by using compounds or substances which can set osmolitic regulation. This study aims to determine the effect of the use of silicon (silica) on the four morpho-agronomic characters of soybean varieties tested. The study is designed by using a Factorial Randomized Block Design basis and implemented at the Faculty of Agriculture experiment station UPN “Veteran” Jawa Timur. The results showed that there were are significant interactions between treatment varieties and silica concentration for of the variables; the number of branches, number of pods per plant, and seed weight per plant. Character of each variety show varied responses to the application of silicon. Silicon concentration of 20 cc / l increased the weight of seed weight per plant and seed yield potential per hectare.
